Your best bet for charging alkalines is get one of the $10 rayovac NiMH chargers (the black one, not the grey one or the fast charger).

Works like a charm, does AA and AAA and only costs $10

All the usual warnings apply if the cell leaks and you eat the fluid and that sets your house on fire, don't blame me. but i do this all the time.

Most alkaline cells are primary cells. That is, they are not designed to be recharged. In fact, the only rechargeable alkaline cells of which I'm aware are the Rayovac Renewal cells, which as Comatose suggests come with their own dedicated Rayovac Renewal charger that also charges NiMH. A few people have tried recharging primary alkaline cells. But if anyone recommends to you that it is safe to do so, be sure to get their attorney's name in advance.

I am asking about the Rechargable version. We have about 30 of them (Rayovac) and they are now worthless using the Black Rayovac charger. Most have only been cycled 4 times over 6 months in our fleet of Lego Mindstorm robots.

A lot of money for 4 charges.

Victor,

Unfortunately, everything I've seen and heard says that what you're seeing in the rechargeable alkaline performance is about typical. If you want something that's reliably rechargeable for more than a few cycles, rechargeable alkalines are not a good choice.

The rechargeable alkalines are apparently very fragile. If you read the fine print, it says that they work best when topped off frequently. As I understand it, these cells will not last long if discharged even to ~50% capacity before recharging. Under optimum conditions, I believe they are only rated for ~25 charges. NiMH is vastly superior.

I will warn everyone I know NOT to buy them. NiCads are much better also.
