Hi OM Doug,
Your'e right, I'll have to open the pack!
A couple of years ago, when the pack did not accept charge, I could revive it by momentarily applying 12V DC directly across its terminals using a 1A regulated power supply.
No luck this time, so I thought I'd open the pack and 'shock' the cells individually.
Before that, a voltage check on individual cells would perhaps reveal the defective ones.
I suppose I'll end up replacing the lot with the new 2100 mAH NiMH type. However I am wary of soldering the jumpers, lest the cells be damaged due to heat.
Many thanks for your tips.
