I have been using the Pure Energy rechargeable alcaline batteries, unlike most rechargeables they give a full 1.5 volts. The batteries themselves generally cost the same as your major name brand batteries (I've found them for around $5 CAD/4 pack of AAs), although recently they have been harder to find. Lifetime between recharges is pretty good, I get about 2 months of use per recharge on my cordless optical mouse. According to the manufacturer you can recharge the batteries up to 100 times, havent run into one yet that wouldn't hold a charge, been using them for at least 4 years if not more. Another nice thing compared to most rechargeable batteries Ive seen is that they come fully charged right out of the package.

When I saw this I immediately thought of a BOFH article I read recently.
