I have a few dead rechargeables that I would like to rebuild and am in the process of doing that to one pack with 1/3AAA NiMH cells. I found a link on ***** for rebuilding with 2/3AAA cells and using a DC adapter to charge the pack. Any one have experience rebuilding packs in any fashion? and if so what were the results? Any other setups used? I have some rechargeable N cells that I can get charged in a charger but I can't seem to get to work in the 41. The button is very small on the positive side. Outside of that, I'm just using Energizer alkalines. Is there any chance there is a "rebuilding batteries" chapter or appendix in the upcoming book Geoff? -Kevin

I use alkaline 'N' size - overpriced, but (still) readily available. Calculator only (no peripherals) gets more than a year life out of them. In my experience rechargeables are waste of time and money.
