Just FYI when charging two batteries you should use slots 1 and 3 or 2 and 4 as stated in the instructions. The circuit board can get hot when you have two cells charging at .750 mA next to each other.
Yes, accept it will only charge at .750 if the 2 cells have slot separation. Next to each other they'll be at 350mA.
Ahh, that's why they want you to do it that way. Thanks for the info.
+Syrbuff hey my digi d4 charger charges both batterys at 750mah when in slots 1 and 2 yes it does get warm but not hot
+Jay Hughes okay, good to hear.
Mine run fine with all slots filled, they don't get hot or even warm if I just use slots 1 + 2, that's using 9A EFest IMR's and 7.5A Torchy IMR's.
I don't use it for anything but rechargeable AA's, AAA's and 1650 or 14500 IMR's.
Just picked one up. Thanks for the review. Anthony.
Looks good Grace. Just make sure you get a good charger for your batteries. Take care.
Quick, no BS, and covered most of the important features and traits. So much better than that Mr Baz guy.
Thank you.
Thank you.
Mr Baz Guy chats crap and waffles on
Foxnovo F4S does turn off the backlight after a few seconds, but the foxnovo has a very loud buzzer.
Does the D-4 tell you if you have a weak or battery that should be disposed of ?
No it doesn't.
Thank you for using a TRIPOD (or other support) for your video. Nice steady camera work. Nothing much worse than fu$@!&g camera shake while trying to watch a video. Spread the word to others!
Steve Wayne Thanks. You're welcome!
I own Maha C-9000. It is only for AA/AAA, but... can deliver up to 2A per each channel even 4 slots are set! This 375 mA limit is a bit ridiculous...
+Krzysztof Skibicki Also twice the price. Apples and oranges, but yes, good charger
Teapartyla True. I use D4 only for 18650. They are Li-ion so you can just charge them. But AA must be discharged before charging... So only in Maha.
Personally, I have 4 sets of 4x 14500 IMR's, the charge time isn't that long at all, 375mAh may sound a little low, but if you just charge 2 at a time, the 750mAh charge is just perfect, you don't want to be dumping massive amounts of current into a single cell.
When the battery is at almost full capacity, it slowly reduces the recharge rate to below 350mAh, which is great as it doesn't overstress your batteries and keeps them cool, making the lifespan of the cells longer, plus batteries charged at a cooler ambient temperature, for example by an open window (as long as it's not raining!) or fan last longer in general, both during use and when recharging them repeatedly over time, I'd rather take the "safe" option and charge at a more "comfortable" rate for the cells than just shoving in as much charge as fast as possible, and what's 20-30 minutes in the grand scheme of things? That's why I have 4 sets of 4, I can always have some ready to use and the rest in a safe, plastic camera-battery boxes.
My LiPo Charger (a Turnigy S60) charges a 132 Amp (2200mAh 60C 2S (8.4v)) in about 30 minutes from storage charge, at 2.2 Amps, which isn't that long a time at all.
great review! I just recently purchased one online! Thank you!
3:18 torch nerd status confirmed. ;)
4:13 mA not mAh :) I've just ordered my D2 and can't wait to play around with it :)
+Brian Su You are correct. mA = rate of charge. mAh = capacity of a cell.
Do you know Hyman Roth from The Godfather II? You sound like him.
Thanks for the efforts you putting in to make these Videos for others. Will the D4 allows you to check the true capacity of these 18650 batteries?
No it does not.
So sad. I was really wanting this feature. Sales ppl either dont know the true capacity or they do and wont always tell you if youre being sold a sub-par item.
my display brightness too low even cancel nocturnal mode. is lamp of display is weak.
okay you're in love with this D4 but you also think the opus BTC 3100 the guy said power focus what price should I get these at are these the ones that have I'm just starting out in this battery pack repair start me off correctly.... I have heard that some of these charges burn up and start smoking....
Cara,apesar de não entender bufunfa nenhuma da lingua, eu acompanhei o comentário pelos gestos, movimentos e modo de funcionamento do aparelho, valeu!!!
Thanks for the review. :) I'm buying this one next year :)
You didn’t get into if you hold down the mode button. It changes to LifePO4. Since I just picked this up I have no idea what that is. It makes the lithium ion batteries I’m charging now look like they have a higher charge somehow. Should I not even bother with that mode? If I am charging 18 650s?
You're correct. I wouldn't recommend charging 18650's as LifePO4's.
hi. no one shows AA or AAA or C type batteries
Nitecore D4 or Xtar VC4 ? can decide between these 2
in this video i saw 1 bug. when you added red battery charger showed 4.08v and full charge, after 2 mins it shows 3.58v and minimum charge.
Got this, love the d4
watched all your reviews, going with the Opus - easy choice, thanks
Great! I think you'll be pleased.
got mine a few months ago and everything was going smoothly
but now i put a battery in there CC lith ion and it goes to 5 bars then back to one and it continues to blink at one bar
google has no answeres for this
i tried wiping the silver connectors with a cotton swap but no luck
does anyone have any idea what is going on??
They don’t charge at 2amps anymore? I have a old charger that I choose in between 0.5 1 and 2 amp.
In the charge mode what does the CV mean? On your screen its showing CC. How can I tell what the mAh is of the battery when fully charged? Does this charger have that facility?
Lots of questions very sorry.
Sorry for the late reply!! CC= constant current. CV=constant voltage. Since the D4 came out a few years ago, it doesn't have some of the more advanced features of current-day chargers, therefore it can't monitor mAh... only battery voltage.
Hope that answers your questions!
Perfect thanks for clarifying that for it is much appreciated.
Hmm a very useful charger for Li-Ion battery owners and AA owners! I wish my AA charger had a backlight but it can supply more current than this so I guess no need to upgrade.
I have keep power 18650,s that are probably 10 years old and have probably never really been used , do you think there still good and how would I know if there not ? I recently ordered a nitecore SC4 because I was told they tell you if a battery needs to be replaced , Iam hoping ........... its obvious that Iam no electronic guru .....lol
The only way to know for sure is to put them in a charger and see what happens. If they're 10 years old and haven't been used they might be completely dead but many chargers can revive dead batteries. Keep power is a good brand.
Thank you for responding , I did what you said actually yesyerday with four of the batterys thus far and all for still had 80% of their power still , so I just topped them off , I still have others to do , Iam sure most if not all will come out the same ........ Iam waiting on my SC4 I just ordered to try it out.@@Lightsngear
@@donjenkins1636 that's terrific!! Lithiums are great 😃
Hi does this one have a refresh option, it has something called(Foreknow the battery life) can you please explain what that means?
Thanks
Looking for the same
Who's here for Vaping?!
me lol
+Agumwicak Cahyo lol the charger is awesome buy it
+Maxx S. im planning on my budget :)
+Agumwicak Cahyo hahah hey I feel ya man.. I saw this video before I bought it. I've been using it for a month now and man it charges quickly and efficiently!
+Maxx S. im going to buy it this month
when charging 2 batterys in this charger should i have them both in the middle or does it matter
you forgot to say , when you press and hold the slot button it says "low" , on the bottom right , on the screen , and what it does ?
Okay thanks. I'll check that out when I get a moment. You may do the honors yourself if you'd like!
I got the same, but mine is the model with 2 battery slots only, but i think i got a faulty nitecore. The reason is because for me it charges the AA batteries too fast..less than 1 hour. And the next day without using the batteries , if i place them in the charger again one is not fully charged and the other one starts to charge and shows half charged. can you tell me much time does it take to charge 2 AA batteries????
hello! can this charge an eneloop pro with 2550mh capacity? can this fully charge it at 2550? thanks!
pol divina Yes it can.
Yep, it'll charge anything it says on the box (plus probably some others) to their full, true capacity, it's an "intelligent" charger so it knows exactly how much power is required to fully charge a cell of virtually any mAh or Current value safely.
I've used mine to charge all manner of batteries and it does so quite quickly, just leave them to "rest" for 10 minutes or so after charging before using them, just to make sure they don't get worn and thereby increasing the batteries internal resistance, causing them to under-perform.
Does it measure battery capacity?
No it doesn't.
@@Lightsngear Thank you!
*Does it discharge Ni-MH / Ni-Cd batteries before charging them?*
Igor Igor no it doesn't
Have you tried the 12v DC input with slightly higher/lower voltages for extended loads and times to see if it had wiggle room?
No I haven't.
why does the 3rd battery at first show 4,08V and almost full but after a while drops to 3,58V practically fully drained?
PI37U When you say, "after a while" how long do you mean? Is it a li-ion or an NiMH? What make of battery is it? I must say I've never had that happen, except for when a battery is first placed in a slot, the 'bars' will show it full for a few seconds...then it'll stabilize to where it's showing the correct current charge.
Syrbuff Was referring to this video.@4:17 you put in the 3rd battery wich shows at 4,08V until @5:21 it finally drops to 3,58V. So it took the charger over a minute to determine that the 3rd battery wasn't full but actually fully drained. Would like to know if that particular battery was an old/faulty one and if it wasn't, why it took so long for the charger to start showing real values.
PI37U Thanks for pointing that out! I hadn't noticed that before. It's a valid question! The battery is an IMR 18350...and neither old or faulty. I'll need to test the battery further though. Thanks for noticing.
Syrbuff Ok. Report back if you come up with something. Just curious since I just ordered my very own D4
Nicely done.
I don't know if you can answer this, but I recently got one of these on Ebay. When my batteries (mainly 18650) are almost charged the mA output from the charger gets really low, between 10 and 60mA. Is this normal for the D4? I haven't been able to get a straight answer from anyone. Thank you!!!
Hi. This is normal. All good chargers do that. I believe it's a safety precaution...so the charger doesn't overcharge the battery.
This is because it switches from CC constant current to CV constant voltage at 4.2 volts.
Yes, that's completely normal in order to safely charge your batteries without overheating or just dumping charge into the cells as this can radically reduce the overall lifespan of your IMR's. It's just a safety feature and a welcome one at that!
Now I have to decide between this one and the Thrunite MCC-4. They're both about the same price and have the same features; only this one has the charging display light "off" switch. That feature is unimportant to me though, so again.... which one?
I would only need this for 18650's. I already own a PowerEx MH-C9000 for my AAA & AA Eneloops.
Any suggestions?
btw: thank you for your video!
posting id I'm not familiar with the MCC-4. There seems to be a lot of new chargers out these days. It all comes down to personal preference, and choice of features I think. The PowerEx is good for NiMH's. At least with these newer units, they handle both NiMH and Lithiums equally as well.
I'd go with the Nitecore, I've had mine over a year and it charges all kinds of rechargeable cells, I prefer the feel, the build quality and finish of the Nitecore, I'm not using it for vaping, I use mine for Nerf blasters where I can't fit a LiPo in the battery tray and just use stock motors.
The Nitecore also has an ability to "resurrect" as best it can within reason, a fully drained and left for a while discharged 14500 or 18650 that would ordinarily be completely useless and only worth recycling (or binning), I'm sure it does the same with other rechargeable batteries too.
Thanks for the review. I am considering to buy this charger but I have 2 doubts that maybe you can clarify.
1. Is the Nitecore Digicharger D4 noisily?
I have a Z4 charger that is very noisily, making a permanent whistle while charging.
2. Is Nitecore Digicharger D4 compatible with NiZn 1.6 volts AA and AAAbatteries?
The factory says it is compatible with ALL batteries, but NiZn is not quoted. I sent an e-mail to the factory, but got no answer.
Many thanks for your time preparing the video and answering the people!
Formigo Atômico Thanks for your questions. The D4 makes NO noise whatsoever! There's no internal fan, or anything else to cause any sounds. The D4 can charge 1.2 volt NiMH (AA & AAA) batteries as well as 3.6 & 3.7 lithium-ion batteries. If you'd like to read more, and see additional pictures, (as well as buy it) you can click lightsngear.com/?p=1408 where you'll also find a purchase link.
Formigo Atômico Sorry, I didn't address the 1.6v. Do you own many NiZN batteries? Tests and reports from users have shown that they don't perform or last as long as 1.3 volt NiMH's. From what I've seen, an NiMH/Li-ion charger won't charge NiZN batteries. If you don't have any 1.6v batteries at the moment and are trying to decide whether to get them...I would seriously suggest only getting NiMH. You can do so much more with an NiMH charger than you can with one that only charges NiZN cells.
Syrbuff
Thanks for your useful answer.
I have a number of NiZn batteries that are reaching the end of the service life. The good is that they have a higher voltage (1.8 volts when full charged), but they loose power fast. Now they last just 2 weeks in my wireless mouse that requires a single AA.
Seems that the users are having a good experience with NiMH batteries and is likely that I will adopt them. I am considering the Rayovac Platinum that has a reasonable cost and good reviews.
Glad to speak with you!
Formigo Atômico Thank you! As my final comment... (for what it's worth). I won't badmouth the Ray-o-Vac...BUT, Eneloops are STILL the "gold standard" among NiMH users, as far as power retention and lasting quality are concerned.
Great for the price, but I don't like how current drops if you put in more batteries. Also don't like that it charges at 750, that's gonna get my eneloops super hot. I guess this would be good for a spare charger to charge my 18650's
+bigflytrap Yes, 750 is the top current. But I've never known Eneloops to get anything more than warm on that setting. I charged some at 1A the other day and they were fine. However if you put 3 or 4 in it, it drops to 350.
I charge my AA eneloops with the lacrosse charger at 500mah, they get almost burning hot. I don't dare try it at anything higher.
bigflytrap
Wow! I have a Lacrosse too. I always charged them at the maximum...700, and never noticed them getting hot.
+Syrbuff It may depend on the generation of eneloop, there quality is still good but the chemistry between generations is a bit different. also the amount of wear could change internal resistance. I have the second to newest generation ones and they'll take almost any amount of current my charger will give them and they only get fairly warm.
connly33
That makes sense. Thanks for the comment!
Does it measures battery capacity?
Isn't there enough power coming from the 110-120v outlets to power all 4 little batteries at maximum rates?
RedRider1600 Yes there's enough power, but the charger dictates how much current it feeds the batteries.
thanks for the review
***** My pleasure! Thanks for watching :-)
Does this come with a wall charger by default ?
Yes.
I bought the same one a few days ago an the first two slots keep on blinking at 1 for like thirty mins.your second slot started blinking at two bars within 1min should I tell them to give me another one and return this one.thats y I don't like buying stuff online😢
Nice job Ben
+Matthew Mutchler Thank you sir.
So there is no way to display current total mah of the battery being charged? Do you know of a good 4 bay charger that can do so?
No not on the D4. Of those that I've tested, none come close to the Opus bt-c3100 for getting that kind of info. Shortly, I'll be reviewing the new ESYB 4-bay Bluetooth charger that I believe gives mAh totals. My Opus review is already on my channel. ESYB in a few days.
Awesome I'll sub. I assume the opus bt-c 3400 is a newer/better version of the 3100
JAY LEE
It was an update, yes. But what differences there were are quite minor.
Xtar vc2 or vc4 brother do that and they are really cheap
+foox2k I got an Opus BT-C3400 3.1 so I could charge/analyze
That is really to bad that the total charge current is dropped down when more batteries are added. My charger doesn't do that. I can set the charge current up to two amps on two slots and 1 amp on the rest. It is similar but has more current so that I can fast charge a cell if needed quickly. Fast charging shouldn't be done very often though as it is bad for the cell.
The D4, although a good charger, has been around for awhile and doesn't have the larger currents that are available on some of the newer models.
Is it hackable? I've got D4 and am wondering if 750mA could be increased to an amp or two by replacing some components inside.
I don't know... but I wish I did!
is it correct that this only charges batteries? It can not discharge and refresh batteries like the BT-C3400?
+lifehackertips Correct. Not all chargers are analyzers too.
Ok, now I'm not sure which one to get, the NITECORE D4 Digi-charger or the Fenix ARE-C2 Advanced Multi-Charger?.....both are about the same price.
Josef AcGuire That's an interesting charger. Looks to be a bit more expensive than the Nitecore. They probably operate similarly.
Yes, I think both of them, Nitecore & Fenix, operate similar but I like the Nitecore better. Anyhow, and since you mention "expensive", here is the the latest OPUS BT-C3100-V2.1 which in my opinion, easily can be one of the best chargers this year!! Selling on Gearbest.com for $42.26
www.gearbest.com/chargers-batteries/pp_71596.html
Josef AcGuire The Opus is a pretty cool-looking charger ... although a tad pricey. Good features though.
Great overview. Thanks for taking the time to put this together. Helped a lot to cement my decision to buy this unit.
Chris topher You're welcome.
can i charge Lithium Manganese Dioxide (LiMnO2) with this charger?
how do you tell if a battery can no longer sustain a charge (dead) using the D4?
It'll show ERR on the slot selection of the dead cell.
Lo malo es que cada vez que se añade una bateria baja la potencia de carga de todas las anteriores.
so far so good..would it be safe to leave them charging overnight?.
Do you mean actually "charging" or having completed a charge and letting them sit in the unit? If you put them on a charge and then went to bed...I would see no harm in that. If they finished the charge at 3 or 4 in the morning and sat until 6, 7 or 8... again...if not done repeatedly, then that should be relatively safe.
Syrbuff yea i meant lettin them charge while i sleep thanks for the reply :)
Nice review. I got some 8800 mah 18650 batteries do you think i can fully charge them?
diettelo 8800? Huh? What brand of battery is THAT? If it says 8800mAh on the label...that's the biggest capacity exaggeration I've ever seen! Yes, you can charge ANY 18650 on this...but please check your typing and let me know if that's what it says.
Exactly...this is what i need.
I have GP Recyko+ Pro batteries with GP U411 charger. They overheats so much while charging. Can I limit the current for slow charging with this charger?
Murat Yılmaz If I understand correctly what you're asking, the D4 can charge at a lower current; 350mA, so maybe that will help.
That helps thank you
I know my i4 doesnt do well w aaa battery's but i mostly do 18650 li-on and nimh aa but it would be nice to have a single charger for all my batteries. i guess im wondering if this charger would detect aaa nimh and charge at lower mah?
Kurtist justice Hi there! I haven't had issues with anything I've tried in the D4. I don't use AAA's that much, so I hardly ever need to charge them. The D4's output can't be selected, so depending on number of batteries being charged, it'll be either 350 or 750 mah that the cells receive.
Try vc4 you can turn off the light on display
I have a Digicharger D4 and there are many options for charging my 18650's.
For charge mode there are cc, cv,-dv/dt and low. What do they mean?
+Frank Sblends I don't have the charger in front of me, but I'm not sure that those are charging options. "CC & "CV" usually refer to "constant current" and "constant voltage" which are the algorithms that the unit uses to charge.
Fenix ARE-C2 will charge 4 batteries at 1amp each
Nice review. Thanks. Have you had a look at this one? Powerfocus BT-C3100 V2.1I think it is even better than the one you are showing.
Thanks! I already reviewed Opus' bt-c3100. Great charger!
hi, can i ask why does it say full but when i remove the batteries and put it back again it's still charging with the slots not fully charged.
Brian Check Most of the time, when batteries come off the charger, they'll drop back in voltage after they've sat for a few minutes. Chances are when it's on the charger again, it should be just a hair below FULL, and shouldn't need any additional charge.
Awesome! Thanks for the reply. Can I ask one more question? Usually, how long does it take to charge AA battrries with the capacity of 2500?
As you probably know, battery charging time depends on a lot of factors. If you're question pertains to the D4, then maybe about 4 hours.
thanks!
I have rechargable alkalines that I love because of the 1.5 volt and when they die I'm thinking about Li Zin 1.6 volt will this charger handle those batteries? I also have a collection of Ni Mh's for items were the voltage doesn't matter as much and obviously this will handle those. Anyone know about the others? Or is there a good charger that will?
I would have to look into the others you mentioned because they don't sound familiar.
just got one not as happy as I thought I would be ,.. seems to charge longer than it should meaning it seems to hang for a long time before saying done while doing so the charger it self gets hot, my luc v4 don't have none of these problems but it's only for my vape gear
Most chargers "hang" for awhile as the charge completes, due to the drop in current that occurs. A rise in unit temperature should only be on the bottom.
What is our argument when you say bt-c3100 is better then Nitecore Digicharger D4 ? I am planning to buy one.
Also What is about BT-C3400 ?
BT-C3100 simply has more features and charges with higher current options. I really don't think there's much difference between the 3100 and 3400. If someone needs to correct me, that's fine.
9V batteries are missing... also, I found that it doesn't like when batteries have dropped below ~0.75V, it gives error and you have to manually re-try(sometimes many many times!) to give it enough voltage so it starts charging normally. Otherwise, a solid charger!
+Sandw0rm 9v batteries are missing? They're not rechargeable? And 0.75 volts??? What type of battery are you referring to? NiMH or Lithium? NO lithium battery should ever be drained below 2.8 volts. And if it was...the XTAR chargers are about the only ones I know that can "revive" batteries taken down too far. NiMH can of course be drained much farther.
+Syrbuff I have rechargeable 9V batteries(Ni-MH). Got them pretty cheap from eBay(I think less than 2€/pcs). I'm using them in smoke detectors and other 9V devices I have. I'm referring to NiMH batteries, very old and poor ones, too. I read from batteryuniversity.com(batteryuniversity.com/learn/article/how_to_restore_nickel_based_batteries) that to restore NiMH batteries, you have to drain them to 0.4V very slowly(~20mA) and then charge them.
I'm looking for a device that can do this battery reviving or draining atleast, I found some very expensive battery chargers(~+60€), maybe I have to DIY with some led to drain them to 0.4V...
Sandw0rm
Okay... now I understand.
+Lightsngear I'm pretty sure my Nitecore Digi D4 can "revive" batteries that have dropped below 2.8v, I know you should keep them at a minimum of 3V, but sometimes you don't notice immediately and they get over-drained, but my Nitecore might be a newer revision that has that feature.
Can this work with 21700 batteries?
i bought it, when it gets 80% of battery it says complete. do you know how to charge 100% ? or my charger is damaged ?
suckNWO So.... You're saying that the charge indicators stop flashing (indicating 100%) but the battery is only at 80%? Have you verified battery voltage with a multimeter following the charge?
You forgot to talk about the low charge option.. Press mode button 3 seconds.
Thanks for mentioning.
does it squeal?
Which is better the Xtar VC4 or the Nitecore D4? I am going to use the charger to recharge 18650 li-ion batteries. About 3 to 4 at a time.
Both chargers will do the job. However if charging time is an issue for you, then I might suggest the XTAR, since for more than 2 cells at a time, it will use a slightly higher current. The D4 will charge at 350mA if more than 2 cells are charging at once. The XTAR will use a full 1A current when charging up to 2 cells at once.
With 3 or 4 cells charging, the VC 4 will use 500mA, and the D4 will use 350mA.
+Syrbuff Thank you! I was a bit concerned by the issue of dominant charging bays. I figured both the VC4 and D4 would have this issue. But I was trying to figure out which would offer the best balanced charge for 3 or 4 batteries at a time.
Though admittedly one workaround could be to alternate each battery through the charging bays. I'll be using 2 sets of 3 LG 18650 batteries which I'll be "marrying" to my device. Which is why I'll be labeling them and alternating them among the battery bays of said device. So I guess I should do the same when charging them.
Thank you again for the advice. I'll go with the VC4 in that case.
Please keep these informative videos coming!
GeoD F
You're welcome. Sounds good! And yes...there's lots of competition out there today, and trying to keep on top of new technology is a challenge!
GeoD F the xtar vc4 is a much better charger in my opinion I just bought the night or did you fall out of your convenience 35 bucks at my local vape shop, kind of got ripped off too but all in all I was happy for the convenience for my 3 LG hg2 18650 as well as a Digi 4 charger for $65 out the door.
Does this charger hold and charge flatop batteries like efest 3100mAh flatop?Thanks
MORDANEUS SA Yes it does.
Yes, it charges my EFest Flat-Top 3.7v 9A IMR cells and my Torchy 3.7v 7.5A IMR's without any issue, just make sure you seat the battery properly, I suggest pulling down the spring-loaded "tab" then carefully dropping the battery into the slot then gently letting the metal "tab" slide back into place holding the battery securely.
Does it have a discharge capacity feature?
No it doesn't.
Thanx
never said anything about holding down the mode button!??? what does it do I know it changes from regular to Low and one other setting anyone know?
+ekreed69 While the unit is charging, the display automatically toggles back & forth between elapsed charging time, mA current, and battery voltage. When the mode button is pressed, it toggles the display the exact same way. It simply allows you to view each one a bit quicker than waiting for the display to toggle by itself.
@@Lightsngear nah, he's talking about holding it in not just pressing it. It goes in to low charge mode if you hold the mode button down for 1 sec.
Thats why im here, im just about to buy a new set of 18650's and im wondering if charging on low mode really does help with battery longevity as ive seen suggested.
when I hold down the MODE button, it goes into LOW? What does the LOW do?
I'm not near the charger right now but doesn't that simply dim the display?
Syrbuff MODE button, not SLOT.
+Kascaded I'm sure the manual explains it.
Hi if you put all 4 battery how long that take to fully charge then if you put 4 3100 mha
So, if I'm understanding your question...you're asking how long it takes to charge 4 - 3100mAh 18650 batteries? Naturally it would depend on what voltage they were when the charge began. But, seeing as the D4 only charges at 375mA when ALL four slots are being used, it would take awhile. I'm only guessing....but even if all 4 cells were at 50%, I'd say 7-9 hours.
Thank so much so the s know big deal for me to buy one my nitecore tm charges the batteries I thought that charge take between 1and tree ours so if hat take more then 4 is know that good deal thanks for answering my questions
MrTarzan150 You're welcome. I hope it helped!
+MrTarzan150 Do You Speak English?
Does it support discharging?
no it doesn't
will it automatically stop charging when the battery is fully charged to prevent over charging? Let's say you put in your battery to charge before you go to bed and not worry about it
+GIN BULAG You can certainly charge overnight without too much worry. To my knowledge though, it will provide a low-grade trickle-charge. Again, overnight isn't a problem.
thanks
Nice vid. Thanks for the info.😀
I got this yesterday in the mail, everytime i turn on it it makes a rattle sound, like something is loose and falling around in the device.. I'm kind of frightened..
Return it using the return policy
There are two connectors can I use them both at the same time?
What do you mean by "connectors"?
Lightsngear on the back there is two options to connect the charger
You would never need to use both at once, because they're both for power sources. When using at home, the "yellow" connector is for a standard plug. The other single connector (if I remember correctly) is for "DC" input, such as in a car, where a 12v socket is present.
does this have a discharge function?
No it doesn't.
Are there any 4 bay chargers that can discharge all 4 bays?
Yes there are. Any charger that CAN discharge, usually has the option of performing the function in each bay. Check out my videos on the Opus, Zanflare, and Tenergy 4-bay chargers.
Wondering if it can charge four 26650 batteries simultaneously.
No it can't -- but this one from MiBoxer can; amzn.to/3pYdRJn
@@Lightsngear Thank you so much !
@@silenthill1035 You're welcome!
I got a question in charge mode
What does low setting do
V P It charges at a low of 350mA.
Would that be better for the battery life when charging and would it prolong use when I'm using the battery?
V P It won't prolong battery use, but some folks believe the lower current is better for the batteries in the long run.
Thanks for the info
mansour albaloushi You're welcome!
did you pay for it or was it provided to you for review ???
I bought it for myself.
nice review ,thanks
Very disappointed with the misleading specifications, despite it says in the box it is suitable for Ni-MH C batteries, but the true is Ni-MH C batteries do not fit into the slots of the NiteCore Digicharger D4
Although I don't own any of those, I can perhaps imagine that they might only work (or fit) in slots 1 & 4. Is that not the case?
no they want fit properly in any bay, not only don't fit in width but in height as well, the positive contact just touches it, a slight movement and they jump out and lose contact.
My Nitecore D4 EU charger gets warm is this normal for a charger?
EU? Where is it warm? On the bottom? Normally the charging batteries are the only things that get warm.
They can get a little warm, but not hot, behind the backlit screen.
My batteries hardly ever get warm.
opus c3100 is way better... more amp charging(1A for each... max is 2Amp for 2) and better price
As much as I don't like Efest I'd say the Luc V4 is pretty much the best deal. Cheaper then that suggestion too and also offers 1a charging for 4 and 2 amp for 2
Opus has a test mode also discharges and recharges battery.
I have one of these, I simply want to say that the one I have SUCKS. why? because I have to fiddle with the batteries until this device notices there are batteries in the bay waiting to be charged. it almost seems that the springs have gone bad after only 3 weeks of use ( I charge 4 batteries every night ) ( LGH2 18650's)
+Rompido Chased 4 batteries EVERY night? Are you sure it's not the batteries themselves?
+Syrbuff yes I'm sure. before I purchased this version I purchased the D2 version. that one still acknowledges the LGH2 18650'S immediately after placing the batteries in. while using the same batteries inn the D4 requires fiddling. I can post a reply video if you like
Rompido Chased
I believe you, and it's unfortunate. I guess what I was driving at was maybe the condition of the batteries, or the type of "button" on the top and how contact was being made in the slot. You might want to make sure the positive and negative ends in the charging bays are all the same, and clean too, of course. They're probably fine, but I'm just trying to think of possible issues.
+Syrbuff wow great timing I'm making the video now. should be up In less than 30 minutes
How do you do a trickle charge please?
Paul Basketcase Most chargers will enter trickle-charge mode automatically once the main charge has completed.
hold the mode button down for 1 sec, goes in to low charge mode. (meant to be better for battery longevity)
Does i have the battery capacity info?
***** has mAh info?? Where? I didn't see anywhere that info. only the bars.
romantashev Nitecore D4 can not test the internal resistance (ohm) and capacity (mah). Which is quite disappointing.
romantashev you should buy OPUS BT-C3100 for those features. Nitecore D4 is only handsome looking, but rather "dumb" and lack of battery information.
+romantashev i have the Xtar VC2 and it charges 2 battaries at 0.5a dunno if it charged 1 at 1a neve tried lol
Tien Cheng [...]Nitecore D4 can not test the internal resistance (ohm) and capacity (mah). OPUS BT-C 3100 is the best. Xtar VC4 can not test the internal resistance. Which is quite disappointing.[...] I agree !!!
No conditioning mode..scratch this one off the list..
This is now an "old" charger. Your best bet for additional features is to look at some of the newer ones I've reviewed. MiBoxer for instance.
hold the mode button for 5 plus secs
+ekreed69 holding slot button switches to LiFePO4 mode
