I used it to charge a dead scooter battery. If all lights are solid, check connection to terminals. Seems like it needs to get a good grip to the battery terminals to charge.
Bought this charger for a lawn tractor battery. It charged the battery from 12.5v to 14.7v, which I understand is the correct voltage to preserve a lead acid battery from sulfation. I used my multimeter to know when to disconnect because the charger wasn't giving me a clue to the voltage, was still charging, and was plenty warm. The flashing bar charge state light flashed 100% the whole time. I wished the charger had a volt meter and a detailed description of the three charging stages touted on the packaging. I have learned to not boil a battery unnecessarily.
I bought one of these and there are no instructions. Are all red lights a full charge and is it working right? I have another model and the lights turn green when fully charged.
I noticed that the box advertises this product as having reverse polarity protection. I’d say I am beyond tempted to try this out just to see if the protection actually works. For reasons I will not go into I had two inverters over the period of 12 months and fried them both because of a reverse polarity mishap, perhaps I had a senior Moment but that doesn’t need to be discussed any further. But anyway without taking this thing apart and examining it would anybody happen to know what type of device or circuit within this product creates the actual reverse polarity protection. I’m sure this product is fantastic but what I am looking for is a circuit or some type of device that would allow for protection of an inverter in the event I have another reverse polarity issue?! Yes I’d like to say after two mishaps at work my lesson but sometimes things happen and let’s just say I would be absolutely beyond pissed if I had yet a third mishap and fried get a third inverter because of a reverse polarity issue. It would be nice to find a device or something that would provide my inverter some sort of protection
Thanks for the reply. Mine is hooked up to my car battery for 5 hours. It is still on standby, only. I assume I need to leave it overnight to see it go up in %, right? Thanks again
Unplug the positive lead from the post until centec unit lights disappear then reconnect. Lights should start moving from left to right. I held down the mode button and it started doing stuff not sure if that did but all lights stayed on . I realized this after leaving plugged in all night for nothing
I had a lawnmower battery votage was so low that it didn't know it was hooked up. I jumped it with my car for 5 min and put it back on and it charged just fine.
Depending if it has a BMS that mimics a lead acid battery maybe. I would consult the battery’s manual. This charger is not compatible with naked lithium cells without a BMS
When I plug my charger onto my battery it stays solid red at 10% charge (no blinking red lights going up the power levels) and the green standby light stays on. Is this normal charging or am I missing something?
@@SuperFastRc could possibly be a bad battery, it worked fine but sat for a few weeks in the winter and drained. I jumped it for a few minutes off my car to get the charger to read it now this is all it does. Standby mode should not be lighting up until it's fully charged correct?
@@SuperFastRc Still nothing said about it.. but I did have a dead AGM battery in which this charger didn't light up at all when connected to the battery.. Now that I have some charge in it, my charge level looks just like your's vs all the other videos on here where it will flash at 10% or 20% and now increase from 10% to 100% every 4 seconds. I have noticed now I've left it connected to the battery now and I'm hearing a relay clicking inside. I feel the manual could of been a bit clearer on here.

@@bentonbrowder yeah, definitely not enough information on operation included.
Thanks for sharing! I brought one one yesterday. I’m using it now. ❤
Lights will all come on if fully charged. standby just stays on all the time on mine and it works.
Just bought one of these today alone with a new motorcycle battery 🔋
I bought one of these and there are no instructions. Are all red lights a full charge and is it working right? I have another model and the lights turn green when fully charged.
I notice that the lights remain constant on when totally charged.
Thanks for the post. I also noticed that. Had me worried.
@@stephendanderson5313 Same here.
The other guy said it stays solid when it doesn’t have good connection?
Do i gotta keep it plugged in?
The guy who made the video seemed to have his charger hooked up for some time and he has all lights blinking and I assume his battery is ok.

Thanks for the Video
My standby light is on, all leds blinking left to right. Is it charging? Is that float charge mode? Is there a way to get it out of standby mode?
That is float mode, its reached its full charge voltage. Now that doesn’t mean that your battery is good.
Are all the lights suppose to stay on when the battery is fully charged? Mine keeps blinking left to right.
That means the battery is full
Can I leave attached and forget about it in a hot rod I hardly use
Yes
Will it charge a dead car battery?
Yes it can!
Thanks for the reply. Mine is hooked up to my car battery for 5 hours.

Your battery might be too dead for it to recognize. Usually standby means its not connected or its finished charging
Remember it's only 2 amp charger it's just made to keep the battery topped off it can charge battery but it will take a long time
@@pauljanssen2624 Thanks, jumped it. Then on the charger, yep took awhile to get it up to par.
My lights don’t even turn on 😂

What do you suggest regarding 6v battery?
I would consult the manual probably set to 6v volt mode.
@SuperFastRc nevermind, turns out the battery wasn't attended to enough, it's bad.
Is it safe for agm batteries
I have used it to charge them, no ill effects
Will this work with a lithium battery?

Is the battery any good or could it possibly have a bad cell?

@@williamlittle8428 Yeah at least thats the way mine works
@@SuperFastRc I appreciate it, can't find a whole lot of info on them. I'll get the battery checked out.
My atv battery is at 80% and stuck on stand by mode. What do i need to do??
I think once it hits standby mode it wont go any further. Might be the condition of the battery?
How do you tell when it’s in trickle mode? Book doesn’t t say anything
I think after it reaches 100% it goes into float charge mode.
I’m thinking when the red leds go from left to right AND the green standby light is on simultaneously
Would it be good to charge deep cycle marine batterys
I don’t see why not
not good for deep cycle marine battery.
It doesn't have enough power for marine battery you need a floater charger has to be marine certified
No. Says not to use it for this in the manual.
At best a maintenance charger.
great
Mine worked for a week now can't get it to float charge my 6v battery
Take it to HF they will swap it out
how do you know its a 100%?
When the last light on the right lights up
@@SuperFastRc thank you!!
Thanks
Why doesn't the manual say anything about what the blinking lights mean, so stupid.
Thats a good point, Good question!

It does show what the LED Indicators mean. In my manual on page 11 it shows "fully charged: All LEDs light up constantly...
@@woodycarter7224 yea, but does it tell you what blinking light (all of them) mean?
