I have very good luck with NiMH. I don't even own any alkaline batteries anymore except for the ones that came with remote controls or something. I get the low self discharge ones like Eneloops, and I can run them right down flat and charge them just fine. I haven't yet had to replace an Eneloop, even after several years they're still going strong. Even the ad copy for the chargers generally only promise 10 charges on alkalines, versus 500 to 1000 for NiMH.

Some of the reviews indicate that the charger is not smart at all - it charges the same amount of time regardless of the charge level or chemistry. That worries me. Proper battery management requires an intelligent charger.

There are several other alkaline rechargers on Newegg and Amazon that are still for sale.
