From what I read, they use 1300mAh NiMH for batteries and of course USB for charging...
I think that's for AA, but consider that you can get 2700mAh AA NiMH batteries, nowadays....
And as told before, global warming is just a myth, a capitalistic consumerism myth...
The only thing environmentalists here in my region did, was to close a racing track...
Cause they though that the birds nearby will be disturbed......
ha.... F@ckers....
GOOD FOR NOTHING, both these batteries and environmentalism...
They are good only if you don't have a charger nearby and you desperately need power...
But STILL not so good...
