Nicads have been eclipsed by NiMH batteries.

Both have suffered from loss of charge issues but recent NiMH technology from
certain manufacturers has improved that. Sorry but I forget which brands
offhand.

I primarily use Energizer, but have some Duracell AAA's as well. The odd
thing is that the D cells have 2500mah, just like the AA's. They are no
heavier, and have no more power...

That is because they are just the AAs in an adapter sleeve to make them fit
in the place of a D. They have them in a C size adapter also. When I first
saw these faux C and D size rechargeables at wal-mart I wanted to slap
sombody. You can buy the sleeves here
