Blues: July 2008 Archives

Personally I only use rechargeable batteries - nowadays of the NiMH-type, Nickel-Metal-Hydride - which mark the current optimum between capacity, price and other traits you want from batteries.
They have a high capacity, no memory (like the old NiCd cells had) and keep their charge fairly well, and can be "topped off " - boost charged right before use - with no loss of capacity in the long run. They are also more environmentally friendly than previous types due to a large number of recharge cycles and the lack of the poisonous cadmium and other nasty substances.
The available capacity per cell is increasing year by year, and while 1,800 and 2,000 mAh (milliampere hours) was the norm just a couple of years ago, today's AA-cells have capacities of 2,300, 2,600 and even 3,000 mAh.
