I appreciate NiMH for their economy and being less toxic, but of the packs I've made up replacing NiCDs, I have to admit that NiCD had better shelf charge life. Any new-style low self-discharge NiMH yet in the oddball sizes sometimes encountered (e.g. can you readily get NiMH in 1/3A and 4/3A)? Too, if a device originally came with a constant trickle charger for NiCads, this won't be very healthful for cycling NiMH. Any thoughts about charging solutions, splicing proprietary plugs into an adapter for Universal Smart chargers?
