If they're the ones I recommended, then I think so Spud. But let's not panic. I've only lost 1 out of 14 over the course of a year. And it may have been partially my own fault by neglecting to charge them consistently.

Which brings me to helpful hint #9 - store your IMRs fully charged. If they drop below 2.5 volts they will probably be permanently damaged. So if you play all afternoon with your voltage modded blaster, throw the batteries in the charger at the end of the day.

I think that's what happened to my IMR cell. I left it in a blaster and after a month the internal voltage dropped and the cell is unrecoverable. My bad.
