Subject: Re: Rayovac Rechargable Batteries
Our ~550 kids have had 82's. 83's and now 83+'s and I've been using a
RayoVac, renewal recharger for most of those years. I haven't run
into the leaking/exploding batteries (yet). The biggest problem I've
seen with the Renewals is not getting them recharged early enough in
the discharge cycle. If you let 'em go 'til the screen in on it's
last contrast setting, you WON'T get many successful recharges. Try
to get the batteries pumped back up when the screen contrast is at 6
or so and the batt's will last a LOT longer!
