This doesn't have much to do with the RC Hobby, but I thought since there
are lot of battery experts here somebody might know. A while ago, I bought
the Renewal battery system from Rayovak. I never had much luck with them, a
lot of the batteries wouldn't recharge only after a couple of uses. I think
it's because their intelligent charger is stupid. Quite often cells would
reverse in polarity and I would have to use a 9v battery to zap them back.
Is it possible to use a Nicad charger like the Triton, to charge these
renewal batteries, or will it blow up because they are alkaline?

Basically the RAM cells (Rechargeable Alkaline Manganese) offered by
Ray-O-Vac require a current limited constant potential charge, much like
lithium. The Triton is set up for lithium so the voltages are wrong for the
RAM cells. Energizer offered a similar product some years back, but
recharging alkaline cells just wasn't that successful so they discontinued
it. With the right marketing hype I suppose Ray-O-Vac can realize some
profit, but considering they have had these in the market for at least 10
years your answer kind of lays in the success they haven't realized to any
extent.
