I just bought Nicads yesterday, I didnt feel 3.5x the price for LiIon
was worth it for occasional use. Also let the pack rest a day to cool
before recharging, cells work by a chemical reaction , letting packs
rest has gotten me 20 years on packs. Heat also kills cells, as in
overcharging and rapid discharge,
