I’ve come across a few good links on rechargable batteries recently. Not all rechargables are created equally, and it definitely pays to get high capacity ones and a good charger. Considering how many times I’ve re-used the batteries in my digital camera and shower radio, I’ve definitely saved quite a bit of money even though the rechargables cost more up front.Here are a few sites I’ve come across (mostly dealing with AA batteries) that I’ve found helpful in making some educated decisions:The Great Battery Shootout is fairly up to date and focuses mostly on using rechargable AA batteries in digital cameras.Performance comparisons of some NiMH battery chargers is a little older, but shows that not all chargers charge batteries the same way.Battery University has a three part tutorial describing all types of rechargable batteries including the best charge and discharge patterns for extending long battery life for each type.
