[Greenbuilding] your favorite battery charger (AA, AAA, etc.)?

[Frank Tettemer]

Reuben,

I've been using an UltraLast charger, model number ULCC4H.
It has settings for NI-CD and NI-MH, and will charge AA, AAA, C, D, and 
9V batteries.

I can't compare it in quickness to other chargers, though four AAA can 
take between six and ten hours, while two 9V batteries seem to take 12 
to 24 hours.

I've had it about five years, and it replaced a ten year old Radio Shack 
charger at that time, when I switched to NI-MH batteries.
The charger doesn't feel like it gives off any heat while charging. 
This, to me, indicates a level of efficiency better than the old Radio 
Shack charger, which was noticeably warm while in use.  And efficiency 
is an issue for us, as we live off-grid.

I've "experimented" with a charger/solar PV combo.  Fine if you have 
duplicate sets of all batteries, so as to always have a set fully 
charged and waiting. I admit that I'm not that well organized. So 
it'sawkward, when your flashlight goes dead, just at dusk.

Here's a link. However, I don't see our model on that page.  What are 
listed on that page are chargers for AA and AAA.
