Can RAYOVAC RECHARGEABLE ALKALINE batteries be charged with a Radio
Shack NICKEL CADIUM battery charger? Instructions on package says to
use only a RAYOVAC charger or dammage can occur. True or Not?? Please
help.

Thanks

I think they need to be charged with the appropriate charger, because it
monitors the battery
and they can explode in a normal charger.

They are a different voltage and a completely different chemistry. I
see no reason why a NiCad charger would work properly on them.

You MUST use the rayovac charger. I have one even though I don't use
renewal batteries because they are also excellent Ni-Cd and Ni-MH
chargers that will charge an odd number of batteries and tell you when
each one is done.

NiCd, like lead acid, can be recharged with a constant voltage and will
not overcharge. But the newer battery technologies have different
recharging curves. IOW these other technologies can be overcharged.
Lithium Ion rechargeables are even dangerous because if overcharged, then
they can explode.

These newer chargers monitor how the battery is accepting a charge to
determine when to cutoff the recharge power. This complexity was never
required by a NiCd or Lead Acid battery which is why older chargers
cannot be used on newer battery technologies.

NiCd at constant voltage? Maybe at a voltage too low to be useful. NiCds
are normally charged at constant (or at least controlled) current possibly
with voltage sensing to determine end-of-charge.

NO... Different charging currents and times.
