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.
All rechargeable batteries should be recycled. Other batteries can and should be recycled as well. Refer to our Care and Disposal section to get all the details on this topic.
