are really fantastic for my digital cameras. NiMH batteries are easy to recharge, and
extremely long lasting.
For the AA-equipped cameras, it's well established that standard alkaline batteries are
almost completely worthless in most cases. A few shots with your camera, and you throw
the alkaline batteries away.
I bought my NiMH batteries at WalMart. The brand that I use is "Digital Concepts" manufactured
by Sakar International. I bought
my first NiMH batteries with a charger that accepts either two or four NiMH batteries and
included four of the batteries as well. WalMart also sells the batteries separately.
I bought my first Digital Concepts NiMH batteries in May, 2004. I am still using these original
batteries in March, 2006! These first batteries had a capacity of 2000 MAh.
In September, 2005, I bought four additional batteries with a 2200 MAh capacity.
I found that after a year of use, the original 2000 MAh batteries were discharging too
fast in my camera, but worked great in my little flashlight.
Recharging NiMH batteries.
A nickel metal hydride battery is a type of rechargeable battery similar to a nickel-cadmium
(NiCad) battery but does not contain expensive (and environmentally risky) cadmium.
This is why they are sometimes called the most environmentally friendly battery type. NiMH
batteries tend to have a higher capacity than NiCads.
NiMH batteries do not suffer quite as much from the "memory effect" as do nickel
cadmium batteries, but still require complete discharges in order to obtain the most
efficiency and longest life.
