An interesting thing is that in most applications,
NiMH cells can directly replace NiCd cells. They're the same
voltage but NiMH has a higher energy density so it'll run things
longer. A NiCd charger will work just fine on NiMH cells, it
just takes longer than a higher rate charger designed for
NiMH cells. Some "smart" chargers for NiCd may have problems
where they'll shut down before NiMH cells are fully charged.
<snippage of useful stuff>
Do NiMH batteries have the same memory phenomenon if not fully
discharged as NiCd batteries do? I might like to look at a NiMH
replacement for my Outbound Laptop battery, but the thing keeps its
RAM active even when off (Silicon Disk feature), so one generally
needs to keep it plugged in, and that means recharging after partial
discharges, which is great for lead acid, but death for NiCd. But
NiMH...?
