Durecell AA

I purchase Durecell batteries for the longer charge life and as cheaper Battieries they leak causing damage to the appliance. Recently I have had a number of AA which haven't been in the appliance for long and stopped working due to discharge of the acid. Very disappointed with the product.

Can alkaline batteries be recharged?

Only batteries that are specifically labeled “rechargeable” should be recharged. Any attempt to recharge a non-rechargeable battery could result in rupture or leakage. We recommend that you use NiMH Duracell rechargeables. Paired with one of our different chargers, they can be recharged hundreds of times.
