For what it’s worth, I’ve jump started many batteries in the past. I notice that 30% of the time they simply won’t hold a charge. 50% of the time the capacity is less than half, and the last 20% they seem totally fine. Haven’t had a battery ever do much more than leak under extreme discharging and charging conditions. Had to light an Ultrafire battery on literal fire before it went off like a firecracker. (Disclaimer: I don’t recommend doing any of this at home :P)
Recycle them. It’s not worth the risk. Not at all.
i would be careful with the light these were run down in.it may have a short.thats a possible explanation for this event.
is this an original srk or a more recent one?
originals had a buck converter or 3.
newer have simple fet switch and resistors.hard to get a serious short in these.buck converter can get a shorted fet and draw a bunch till the fet or inductor burns up.
time to autopsy the light.
