The Truth is that most people don't understand unless you are in a hobby with batteries like RCs, that each Lithium Ion cell is 3.7v nominal up to 4.2v fully charged. Those tool batteries usually use the 18650 cells and if its advertising 18v or 20v its usually 5 cells. Higher amps just mean more in parallel to make the run time longer.
If you multiply 3.7v x 5 its 18.5v but fully charged they will be around 20-21v. So that's why manufacturers call their batteries 18v or 20v which is really the same thing..
Chase023 yeah, my 18v batteries show over 20v on lith. Ion
Each battery cell has a nominal voltage of 3.6 volts and a maximum voltage of just over 4 volts.
3.6 volts (nominal) x 5 cells = 18 volts
4 volts (maximum) x 5 cells = 20 volts
That’s it. That’s the entire difference in 18V vs 20V Max batteries. It’s only a matter of whether the company is using nominal voltage or maximum voltage as their rating.
Thanks for the video guys. This now solidifies my choice in the new tools I need to buy after being robbed of all my work tools. 👍
I learn something new everyday! THANKS for pointing this out....I wouldnt have thought that this was a marketing ploy. Good info!
had this SAME conversation with a co-worker, now I can rub this video in his face, thank you Tools In Action !
Hahah I like how you guys used the green screen for the garage background your getting good at using the new equipment.
Hello there, I have a question for you. I have just purchased a Stanley Fatmax drill set here in Australia. It is rated at 18v. I have noticed it is an EXACT copy of the US available 20v Porter Cable drill(which isn't sold in Aus).
Do you agree, apart from colours, they should be the exact same? Considering price, I should be able to use either yellow Stanley 18v batteries or 20v Porter Cable batteries interchangeably. Am I correct in assuming this?
Thanks for setting the record straight! One more thing please... How would you go about pulling this long ass knife out of that big rock at the end of my driveway? Its been driving my family nuts for generations
Nice video. The green screens are looking much better. I am glad you used the garage as the background.
I'm getting my first drill what do you recommend ill be using it for hvac work
Good video guys! Thanks for the heads up! Now I feel better in my new investments I've made in the Milwaukee fuel line! I waited forever to start buying cause I was waiting for a deal and when the buy tools get free battery and charger came out I jumped on it! Got the the big impact wrench and circular saw! Love em!
Thanks man!
You guys moved the desk in the garage nice touch!! .... :)
Please advise if any of the similar looking 20 v (such as black&decker and dewalt) batteries are interchangeable.
Helps me decide which tools to get for my husband thanks guys!
Good explanation of 18v vs 20v. My first day of Tool School and I actually learned something. Good job guys.
Ha, nice green screen you guys. Love it. its great to know for somebody dont know 18v and 20v are actually the same starting volt is over 20V. And all the lithium battey pack has a circuit board to control the discharge when the battery is below 18V. Fancy stuff like some kind of cell safety feature that protects the tool during charging and also prevents over discharging. And most 18v or 20v pack are using 5x high drain18650cells in the small pack and 10 in the big pack. In some country they name their 12v line to 10.8v line as well. Same thing all about how they brand it;) even on the old 18v Ni-cd pack they are usually starting over 20V after fully charged as well. I have been doing some learning to reseach on power tools batteries. It just seems to interest me a lot;) hope TIA will share more about power tools batteries soon. I would like to heard from everyone idea and thoughts.
im buying a bunch of tools for my shop right now im glad i watched this video!!!! thank you guys
YW
Wow. Thanks for this video. I have wondered about this for a bit.
Thanks guys, my new favorite channel
if you take any 18 or 20V lithium pack apart you'll find 5x '18650' lithium cells in series - which is to say that from a technical//power standpoint all brands' 18/20V batteries are identical (about 21V when fully charged). I've been 3D printing adapters so you can use 20V batteries in older '18V' tools for years. curious which brands folks would like to adapt between most (e.g. makita -> milwaukee). right now I just have porter cable + dewalt done
Thanks for making this video. This is something that has been making me chuckle for a while.
yw
I consider myself informed on gadgets and battery technology. I was completely ignorant about the 18 vs 20 volt deal though. Thanks and upon charging my 18v xrp and regular batteries, they do go to slightly above 20v for a few minutes.
Thanks for the knowledge. and you will get your 197th thumbs up.
Good thingi came across this discussion. I steered away from 18 volts power tools because i thought they have less power
Thanks for the clarification!
Glad you guys did this video to clear up the "confusion." Lol. Thanks.
So can I use the 18v charger to charge the 20v battery....cheers
hi, I was thinking of buying an xr 20v dewalt cordless multi tool on eBay US. Would my 4ah 18v European spec xr batterys be ok with this? the tool is sold with no battery or charger.
thanks
The battery and charger are the same and compatible but if you buy USA manufactured dewalt tools in Europe the USA Warrenty on the tool will not work in Europe as its region specific.
The same applies to European manufactured dewalt tools, the European Warrenty will not work in USA. Could be expensive if the tool needs repair or replacement under Warrenty as you would have to pay for it yourself instead or ship it back to the country it was manufactured to get it fixed under Warrenty.
Buying USA manufactured dewalt tools in Europe is cheaper but it doesn't include a any kind of valid Warrenty on it even bought brand new so be careful if you take the risk.
That green screen got me, I was wondering why you guys looked like you were sitting at a nice table. Also good video I was always curious how much power those batteries actually put out.
Cool never knew my 20vmax was a 18v,is thT good or bad?
Hey Guys, great vid again answering a question I was googling for month about 18v XR Li-Ion and 20v Max Li-Ion battery interchangeability as I have few 18v XR batteries and every single time I wanted to take advantage of a great 20v tool deal on eBay USA, I had second thoughts about compatibility.Thanks.
BTW, what is that DeWalt nailer on the wall? Is it the DeWalt Brushless Framing gun or a new Brad Nailer which I have seen nowhere else?!?
YW :} It is the DCN692
In Europe we just call them 18v post and 18v slide instead of 18v 20v as that's the fitting type and there is less confusion than 18v and 20v.
Dewalt 18v slide could be a trade mark if dewalt wanted to do it.
Hi I have dewalt 18v drill can I use 20v battery ??
Knew this before I purchased my 20v stuff. I still went 20v for the designs and compact feature. Btw, green screen?
Amazing... I know a guy that had the huge 18v dewalt combo set, which he sold for almost nothing to replace with a new expensive 20v dewalt combo set...
J Banst 20V is lithium so it will be better than the 18V unless he had nano packs
@@Toolsinaction I agree. 20v vs 18v DaWalt tool power is a world of difference. Also, I like how the lithium stuff doesn't slow down as much towards the end of the battery usage. A caveat there is you don't get much of a warning that you'll need a charge soon, but most of their larger batteries have the push button remaining power indicator. Now you can purchase the adaptor that allows you to put 20v dewalt lithium ion batteries on the older 18v tools. So if you have an old saws all or something and don't want to replace it, you can go this route and maintain one battery standard.
Great Show! Thanks! Let me ask about the Craftsman C3 19.2 volt system. Where does it fit in. Is it also a 20 volt system?
Very Good call Frank. I am almost positive that is an 12/20V why they went 19.2 I am not sure.
can you do a video on dewalt ac adapter dca120 , i wante to noq if it will run my flexvolt tools , drill , grinder and sow .
Does the Dewalt 18V xrp DC9099 batter have the same power and run time as the smaller Dewalt 18V xrp DC 9096 battery.
See you guys are getting good use of the MM500!
At first I was like wow they have a pretty nice table in the garage, then I realized it was a green screen haha.
Soooo can I charge my 20v max with a 18v charger? Or I can out a 18v battery in my 20v max drill?
I was gonna spend the extra 50-100 for the 20 MAX lol thanks for saving me some change
I have a lot of 18v non lithium ion battery dewalt tools I still use and don't want to lug around the batteries any more since I've basically switched to 20v but if i just buy the 18-20v battery adapter are the 18v tools that much less powerful? or are the specs basically the same besides brushless motors
All 18V Li-Ion batteries will settle at 20V when fully charged, and the moment you power your tool that voltage drops to just over 18V, then crawls back up to 20 when you leave them.
This is similar to how all batteries work.
Only difference in power will be come from the tools themselves. But a word of warning, Li-Ion powered tools come with a voltage limit which cuts you off when batteries go too low which wasn't put in older tools so you need to keep an eye on power drops yourself.
MsSomeonenew The voltage cut off will be in the bms of the battery, not the actual tool
I think Dewalt is just trying to seperate the new 18v battery/tool style. Alot of us like being able to use old 18v post style tools with new batteries or vise versa.
Great video guys!
OK my question is this, cause I can't find an answer anywhere. I have an Evolv 18v Lithium Ion drill and I can't find a spare battery for it anywhere. I noticed Craftsman has a 20v Lithium Ion battery that looks about the same as my Evolv 18v battery and since Evolv is made by Craftsman will this battery work on my drill?
Vegas Blanchard Possibly, they sometimes look identical but they add a tab to prevent cross brand charging.
Now that is something that I didn't know! Thanks guys...really.
+David Handley yw
That's great to know thank you guys
Nice throw back Garth! Thanks for bringing that up guys, I've tried telling my pals that and it normally ends in tears. Mostly because I'm like God? Why did you make some people so stupid"? Okay gotta go, Eric told me to brush my teeth so....
The truth will set you free
I've been wondering that for a while now, just haven't got around to testing them.... off subject, in the future sometime could you'll do a review on the Ridgid pro pack shop vac?
Sure, I actually think I have one here. or maybe I gave to to my sister. Ill look
Is the black 20V lithium ion battery interchangeable with the red on porter cable cordless tools?
no
charging time for 18V DC New Design Two-speed selection Lithium battery
hello could you please tell me how long it would take to charge the battery as above - thanks
Hi guys ok I just ordered a 5 inch DeWalt band saw from the us.will my 18v batteries euro batteries fit l live in england
Thank you guys - here in Australia its all marketed as 18v but the prices compered to the states are friggin insane. I'm waiting until my buddy goes to the States and can bring back some high capacity "20v" DeWalt batteries for me at half the price.
+lazzo Outside of the USA tool prices get really expensive even in Europe they generally cost more. I was shocked to see how much Ryobi tools cost they are similar to what Milwaukee tools are here.
Well it depends on what company and what region, Festool for example costs about half as much in Germany then it does in the US.
If the slots match up can you but a 20v on a 18v charger and vice versa?
An 18XR in Europe and 20V MAX US yes
How many cells within the battery? Li is about 4.1-4.2v per cell fully charged. 5 cells?
Awesome thanks guys
Finally, I tell people this all the time, but some people just can't seem to grasp the truth.
Black and Decker did start doing this. I think another reason is to differentiate between old NiCd batteries if I'm not mistaken.
I think so
When are you guys going to do the cordless impact wrench comparison videos? I'm debating between tools and can't afford to buy all. So please make a video soon.
Couple weeks I hope
Is it only the newest battery packs that are like this?
Ben Kempa yes dewalt differentiated their older ni cd post battery tools from their newer slide pack lithium tools by marketing the no load voltage instead of the voltage under load. It's merely to make it clear what dewalt tool one is talking about.
That is interesting, thank you
Great video!
Dewalt cordless tools in Ireland are 18 volts on the drill but I think it is a way to tell the difference between the U.S. Tools and Europe tools because that cost a lot more for the same thing
i explain this to ppl at my work all the time :)
Good job boys
I can't stand when people say "yeah but mines 20volts" then I have to explain it 7 times.....
lol so true
What about older NiCad batteries ? Do they read 20v on full charge ? I could test it myself, but you guys are experts.
LOL We are far from Experts lol I don't think I have any NiCads left. Try it on a full one and see what you get. i would think no though.
Just wondering... if I have a 20v battery.... can I put it on a 18v tool? Dewalt specific.
Well if it is a European 18v and American 20v yes. if it is the old 18VXRP non lithium excluding the Nano then no because the connections are different.
I'm from the uk, I really like the dewalt 20v cordless mitre saw! But sadly it's not been released over here, would I be able to use the 18v XR batteries with this saw? Or are the ports totally different as ive not seen the 20v battery up close.
Luke B They are the same I believe
+Luke B The Dewalt 18 & 20 volt battery have different shapes. They are not interchangeable in the U.S.
I can confirm the 20v batteries work with uk 18v XR as I have the 20v MAX dewalt mitre saw and all my 18v XR batteries work with the saw.
20v max American Dewalt batteries are the exact same battery as the 18 V slide type battery in the UK they will work
Go to google images and look up Top of Dewalt 20v max battery
How about 12v compared to 18/20volts? Is it worth it paying the extra money for the 18/20 volts? Is 12 volts old technology, not as powerful? I’ve recently seen kits at my HD of 12 v drill & impact drivers for a much lower price. Including brands like Makita & Milwaukee still selling 12 v kits at a much lower price, I guess they are getting rid of old stock?
They actually done that to help with confusion when Customer leaves bought the new battery thinking it would fit the old post model. So they just made the decision to call them different volts
Yes, finally! I have given much thought to this.
Can I charger and use 18 and 20 Dawalt's machines and bat. with each other?
If I buy a machine or battery in the US. can I load or use my 18V batteries here in Scandinavia?
No one here at home have been able to answer Me this.
Thank's
Codey is right 18V XR in the UK is 20V Max in the states.
Well, I contacted Worx tool and told them what you said and they replied. 18 v is 1.3 amp and 20 v is 3.5 amp.
Ha! Green screen! Very nice.
I got a new cordless drill that a 20v max and in the owner man it stated that it's 20v no load 18 with a load
can I charge the dewalt 18v lithium battery on a regular dewalt nicad charger?
Frank C
no as the connection is different, new battery is a slide on type instead of the old post type because the new lithium ion batteries require special charging and safety circuitry to stop the battery's over charging and exploding and balances each individual lithium ion cell inside the battery pack to make sure they are all as equal as possible. NIMH and NiCd battery technology also uses a different type of charge method of constant voltage, constant current but lithium batterys use a different type specifically for lithium so even if you got it to charge from a nicad charger somehow with wires from the charger to battery, you would just be waiting for the explosion and fire and gas venting from the battery!!!
Lithium batterys are dangerous unless treated with care and respect and must only be used with the dedicated dewalt charger fully compatible for that battery pack (chemistry and voltage)
HELL no
Hi there.
Would i 'll be able to power an american 12/20 volts MAX XR Dewalt heated jacket with my 18 volts XR batteries from my brand new set of tools. I could just buy the only model of heated jacket dewalt is offering in Europe at the moment, but i'd like a hi-vis model that is been sold in USA.
+oscar amador The batteries are the same
This is craY cray 18v is less than 20v I want those extra 2v ! Where r they at?
Thanks. I always wondered what happened to Chevy Chase. I now know he does tool reviews. :)
What is the best cordless drill for under $60?
+Dominic Torres I like this www.blackanddecker.com/products/power-tools/portable-power-tools/20v-max-power-tools/20v-max-lithium-drilldriver-with-autosense-technology/bdcde120c
Thank you very much you’re you’re amazing
Dam it keep it up guys
I hope that dewalt calls them 20v to avoid confusion with the pod style 18v packs
That's one reason as far as I understand. yes.
Exactly. In my local Farm and Fleet they have the bare tools in the same area. I can easily see the 20 as opposed to the 18 without doing any further research. Grab the box I need and know for a fact my slide packs will be compatible. Why people get so worked up over this is amazing to me. It's common knowledge at this point. I'm mean really do people think 12v is really 12v? Yes Milwaukee defenders I'm talking to you, they do the exact same thing! To me it's not a big deal at all, do your homework and buy what you like.
I always believed that DeWalt made this change when they went to the Lithium Series batteries so that people didn't try to charge a lithium ion battery with a nicad/nimh charger. (Bad news to do this, bye bye battery and charger, most likely)
In addition, it signifies the change over to their brushless lines which are much more efficient. While it IS a marketing ploy used by SEVERAL manufacturers, keep in mind that you can buy replacement 18v Lithium Ion batteries that will run your 18v DeWalt tools. you just have to replace the charger. They have a new charger that will auto detect your battery type and will charge all 3 types (NiCad, NiMH, AND Lithium Ion). That way, you can mix and match your batteries, and only replace your packs as you need to. I personally think this is a fantastic idea, and one that should be pushed harder by tool reviewers such as yourself, and by the Manufacturers themselves. Some tools, new battery technology... best of both worlds!
However, when you buy the new charger, it does come with a new battery also, but it's a NiCad XRP pack. (Stupid! Stupid! Stupid!) I mean, why would I buy a new triple duty charger, and want a NiCad battery to go with it? I'm sure they did this to keep cost down, but come on. What's the point of having a new Li charger if your brand new battery is a NiCad???
We had a 18V XRP lithium Nano. I gave to to the marina and they still use it with no issues. If I can track it down I will test the voltages on it. Great Comment!
Same to 10.8v vs 12v right
thank you guys. i picked up the 18v cause they were cheaper. salesman did mention that there is not much difference but i was skeptical. so if they are the same, would it be fare to say that the 18v would run out faster then 20v ? if your view, what the most commonly used powertool today. if possible could you provide brand and brand name just for us youtubers here.
ruben sharma well the DeWALT 18v and 20v is different. the Dewalt 18v in the US are still NIcad
Tools In Action ? What about these ones then? (DEWALT DC9182)
www.amazon.com/DEWALT-DC9182-18V-Lithium-Battery/dp/B00OKK87FG/ref=sr_1_1?ie=UTF8&qid=1440609726&sr=8-1&keywords=dewalt+18v+liion&pebp=1440609762095&perid=1XYGQVZ80HW34KCFT1VZ
+Tools In Action
Dewalt sells the 18 volt in both NiCad & Li-Ion version.
+Darrell Patton Yep, thats what I was hinting at with my comment/link above. They did not compare the other/older body style 18V LiIon with the newer 20V LiIon.
good info for anyone not sure on the marketing gimmicks companies use! cool use of the green screen, you should throw up random background images for reviews, make it look like you're up a mountain or something!
I was wondering, and this just now came to me, if i could use one of my 18v batteries on my 20v impact or drill (and I'm referring to my dewalt drills and batteries)
flaveNico No, different style
yea Nevermind, after i asked this i remember the 18 volt was totally diff. been a while since i used my 18volters
Thx for that branding information. Those tricky bastards in marketing^^
The usual Lithium-Ion cell delivers 3,6 volts ... so simple math later we know, that 5 cells add up to 18V and 6 cells would be at 21,6 volts.
Now when i take a usual 3.6 volt (btw open circuit voltage) cell and load it with a fast battery charger , that runs normally with 4,1 or 4,2 volts, my 5 cell battery pack ends up with 20,5 volts.
Someone made same research/experiences? Its the same with my drill batterys or single cells.
So i just can say those marketing bastards a pretty tricky ;)
Li ion will take 3.65 volts per cell max without long term damage & reduction in battery life.
Does this mean US ryobi 40v is also the same as European ryobi 36v? I do not see the word max on US's 40v
Taned Pattrawong hmmm good question
Tools In Action still waiting for answer tool master
what about kobalt's 24V?
Would tools that use 18V NiCd batteries be stronger than tools that use 20V Max Li-ion?
no
Green screen is sweet
Just a question I had, howcome they're not making these tools in 40v, wouldn't that make them more powerful, what is the reason for this? Thanks
+John Hansen Bigger batteries. They have 40V lawn equipment
Dewalt has a 40V Line
+Tools In Action technically not true on anything over 2.0 Amp hr. The 5 amp hr has 10 cells with 2s5p. They could just wire it as 10s and achieve 40v. Note s means series and p means parallel
Where do you plug in the air hose ?
lol
All i can say is all my coworkers use 20v dewault or milwaukee and they have to change 2-3 batteries a day... and im over here with an 18v makita getting the same job done with one 2 ah battery
What about from the same company 18 vs 20 volt
Marketing trick to give them an excuse for not making their new and old tools/batteries compatible.
hi guys,can i charge a 20v battery (dewalt) with 18v charger (dewalt)
+haris hap The battery formats are different 18v xrp is a stem pack while a 20v max is a slide. They physically wont work
Yes if the battery and charger are the same type (slide battery and slide charger)
I'm over the pond in the uk.. 20v peak charge then your down to 18v after that..would still favour the dewalt over a bosch,Panasonic or any other tool brand that have ever built Tv's haha
But then again I'm a self confessed Dewalt fanboy,so I would say that..
I see your slowly bringing the new camera gear out...(remote*)...
when is the green screen making an appearance again??
It did in this video. Im a dewalt fanboy too It sucks I want to break free but they just make awesome drills and drivers.
