I've got a typical wally battery that charges fine, and displays the 4 lights when the button is pressed. However, it will no longer power my UA-5 or my jb3 (through a voltage regulator contraption). I've got two identical other batteries that are giving me no problems.
This particular battery was actually the first one I bought last summer, and hasn't given me any problems until now.
Thanks for the help in advance.
I'm not fully understanding what you are saying. have you tried it on another device?

I've tried it, unsuccessfully, on:
1: My Ua-5
2: A voltage regulator that is used for external power for the Jb3.
So it is not sending power, but it charges and shows a charge (the 4 level lights illuminate).
Does that help?
do you have a volt meter?
did you get it figured out?

Yes, I do have a volt meter, how do I test the output without blowing myself up :P

should be able to just stick it in the output. test a good battery first
this will not hurt anything...not even you :P
well, as expected, it is putting out nothing. while the other batteries are putting out about 9.21 volts.
Any way to "reset" these things or do I have a paperweight?

I'll take a look at mine when I get home, but I think you might have a paperweight
Patrick.......I did't see any way to reset this thing. before you decide to dump it, give it a good smack on a hard surface (concrete floor maybe). I have done this to a different type of battery that was giving me a similar problem. It made it work for a little while.

These Li-ion batteries have built-in protection circuits that will essentially shut them down if they have been shorted. And there is a reset if this happens -- you need to plug them back in to their wall-wart charger. This should reset them and allow them to act normally.
I'm not sure if this is the problem you're having, but I'd try this first before giving them a good smack.

I've done that before, but it hasn't seemed to fix it. How long should I leave it on charge?
Thanks. If that doesn't work, I'm going to smack the hell out of it :smash:

Looks like it's time to go ahead and smack it. :D The one or two times I've had it happen, plugging the battery into the charger reset it immediately. Too bad the shut-off protection didn't turn out to be the problem, looks like the battery may have gone bad.
Dropping a car battery is a common technique to dislodge deposits that may be shorting cells. I've done it and had it work..
I don't think I'd do anything like that with a battery type that is prone to explode..
My Wal-Mart battery also crapped out.

Great info. I was at a show last night and was double checking my wires before the opener came on. I must have done something weird as the battery would not work at all after I replugged the wires back in after checking a few things. I was so pissed. Luckily, I was still able to run mics > batt box > jb3. But, I was really surprised when I got home last night and plugged in to find it would work fine. Not sure why the ua-5 shorted it out though...
