Haveing trouble charging batteries and I need some HELP!

[varalMCheelflip]

just posted this over in the technical issues forum but I thought maybe some of the modders here could help aswell

Ok so I was making this 5 volt box mod as some of you may know, I got it to work when I gave up on the 5 volts and switchhed it to run on a a single 3.6 14500 battery

Well now they wont ....ing charge...

I left them on charger for 4 hours... nothing

and aditional 3 hours got me .......

I think it might be this getto ... charger but im not sure
its one I got from mad vapes
AG-126 Lithium Ion Battery Charger


just noticed this but it doesnt look like this one that they sent me

As you can see its smaller and thinner than the one advertized online, output is different aswell

has anyone else had problems with this charger???

Also I dont think the batteries are fried, they seem to have a small charge left on them, just over 2 volts

Is there anything I can do? or is there any advice you guys can offer???

same charger I use... got a pair of 16340's on there now.. also use it on my 18650..

bay 1 on left, bay 2 on right... if charging a single battery put it in bay 1.. positive on the top, plug in.. LED red = charging, flashing red/green fast = almost done... green = done.. no problems for me

I do the same only when I put the batteries in the light just stays green, It worked fine for the first charge now it just wont charge them

 

[Guanu]

Mine only stays green when I put fully/mostly charged batteries on it when I plug it in. May be a problem in the protection circuit of the battery.. is that the only battery you have tried on it?

yeah, i dont have any others

Might I ask what switch you are using? If you have that round ball tact switch this could be bad. the regulator 4 pin saves the switch. Going to 3.7 without that protection may have taken out a under ratted switch. the battery is more then likely fine if that is the case and it sounds very possible to me.

 

[Connman]

You could use a small wire and attach it to one side of that switch and touch the other to see if the atty heats up bypassing the switch. And not to be stupid but don`t forget there is also a main on/off switch. Be sure you didn`t bump that.

its a horn style switch, im almost certain it has nothing to do with that, as it all worked fine when the batteries had a full charge on them, now that they wont charge in the charger im trying to find out if something is up with the batteries or if possibly the charger is at fault

Throw a multimeter on it, see if you're getting a charge.

How much is just over 2 volts? These batteries aren't supposed to be drained past around 2.95v or so. I've got that charger & it works great with everything from 10440 to 18650s for me. What batteries are you using & are they protected? How old are they?

 

[varalMCheelflip]

the batteries are only a week old and ive only charged them once, I wasnt aware you coulnt let them drain all the way down before charging, how can you tell when they are due for a charge?

The ones I use, when vapor drops off, I put them on the charger. Make sure it's not just an empty cart/carto first.
Every so often, I meter them just to see how low they are going. On a 3.7v mod, it's normally around 3.3v when I get a big drop in vapor. Using a Ti board, it will go down to around 3v before it's really noticeable. I haven't made but one mod with a regulator, so I can't really say when the vapor drops off & it's time to charge. I also check periodically to see what the fully charged(solid green light) voltage is. It should be 4.2v.

You batteries are the protected ones, right? What kind are they - 14500, 18650, etc.?

No legitimate Li-Ion charger will charge a battery that has dropped that low.

From Battery U.

[FONT=Verdana, Arial, Helvetica, sans-serif]The safety circuit is designed to cut off the current path if the battery is inadvertently discharged below 2.50V/cell. At this voltage, most circuits render the battery unserviceable and a recharge on a regular charger is not possible.[/FONT]
