Battery Issue

[High_Noon]

A few years ago, I purchased six LS 16340s made by a company called GTL to use in my modded Surefire G2. I think they may have been charged twice in that time since the G2 has been relegated to 3rd or 4th backup.

I just put 2 of these 16340s in my XTAR VP2 charger and one of them refuses to charge. I think it's just a cheaply made, bad battery that failed. Both banks of my XTAR charges other cells just fine.

What say you, should I just toss it?

Chuck it in a bucket of salt water for a day or two (in a safe place outside, away from children and pets) to discharge the battery. After that dry it off, wrap it end to end with electrical tape to cover the contacts and recycle it (lowes and home depot have places to drop off batteries).

ok, thanks.

Just curious - During initialization, after it displays the charge voltage setting, it indicates the open-circuit voltage of the cell in each bay before charging begins (or should normally begin). What voltage is it indicating for the suspect cell? That aside, it's probably like they say about suspect food: 'when in doubt throw it out'.

Lol is that what your really supposed to do with them?

aznsx: It's been consistently showing 0.79.

Thanks. Just my opinion, but for me the risk:reward ratio wouldn't justify trying to use that cell. I suspect that the charger has a minimum voltage threshold below which it will not go into a normal charge cycle. In a zero volt case due to protection circuit it will 'reset' the condition and charge those, barring other issues, but I suspect it doesn't like this very low voltage in this range, and probably with good reason. I'd write it off.

you could always toss 'em in the trash and maybe set the garbage truck on fire.

Thanks.

you can jump charge it with another same battery for a few minutes then your charger can charge it.
