Frequently Asked Questions

Show / hide

Can I mix different battery types?

No, different batteries are designed for different purposes. Mixing a lithium battery with an alkaline battery will not improve device performance. In fact, it will reduce performance and may even damage your device or cause battery leakage or rupture. As well, do not mix different battery brands within a device. Doing so will reduce overall performance and may also cause battery leakage or rupture. We recommend using the same type of batteries within a device.
Show / hide

Can I charge other brands’ rechargeable batteries in a Duracell charger?

Yes, Duracell chargers will charge other NiMH AA or AAA batteries. However, Duracell cannot guarantee the quality, safety, or performance of other battery brands, so using Duracell rechargeable batteries is recommended.
Show / hide

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.
