Dead Li-Ion Battery?

[benyosh]

Okay, i tried the search function and also Google. Is my Pila 168a a goner? It was powering my WE Sniper and all of a sudden, nothing. Open circuit voltage reads 0.7 volts. Do i scrap it or is there a way to revive the battery? The Pila and charger is the old version.

thanks,
ben

Sounds like it needs emergency care - maybe Silverfox will have an idea but my guess is it's a goner. Did you try charging it?

I'd be safe and scrap it. Seal it up in a plastic bag and take it to RadioShack, they recycle them..

Put it in the Pila charger several times and no luck. Also tried it on my ICE smart charger...no dice. Sounds like a bagging and a trip to Radio Shack is in order. Oh well, AW has pretty good prices on protected li-ions. Thanks for the replies.

I'm puzzled. LV protection should have prevented this - or is it a very old cell?

How did it happen? Did the light go out while you were using it? Could you have run it down and then forgotten to switch it off, or could there be a short? 0.7v is NOT good.

I've had several similar failures following storage at cold (-14C) temperature, with AW protected cells.

Are pila cells not protected? If they are protected cells then putting them in the cahrger should enable the protection circuit to close the circuit, if they aren't protected dump em.

I have 21 Pila 600s cells that I have bought over the last 18 months, and I noticed one of my FiveMega 700L WA-1331 bulb maglites would not turn on. Same exact thing. One of the 3 cells was reading like 0.6V and had no response to Pila charger or single slot DSD charger (they would not charge it). The other two from same purchase and in the same light were fine. I figured this may have been an older stock, or just a defective cell, but I got it just after Pila switched to the new cell naming convention.

I have not known what to do with it, so that's great news about dropping off at Radio Shack.

Oops, sorry guys but i actually have a Wolf-Eyes LRB-168A li-ion cell

. DM51, i was using the light when it lost power. The battery was freshly charged and i tested it before leaving for work. These batts have short-circuit as well as over-current protection. I bought this battery and charger from PT-S about 4 months ago.

I may totally way off, but I thought I remembered a post that if the Voltage protection activates, it has to be reset by "bumping" the cell with with a momentary voltage increase. This may have been a dream, I thought I read that information someplace.

Yes - I remember reading something like that too. Might be worth a try.
