Frequently Asked Questions
Why use a rechargeable Nickel-Metal Hydride (NiMH) battery?
Many of today’s high-drain devices like digital cameras require replacing your batteries more often than you’re used to—why not choose Duracell NiMH batteries? They can be recharged hundreds of times.
The Duracell Rechargeable AA battery is ideally suited for powering digital cameras and other devices that require a lot of power. Also available are AAA batteries, useful in small electronic devices such as MP3 players and handheld games. Duracell Rechargeable NiMH batteries and chargers offer you the quality and dependability you’ve come to trust from Duracell in a long-lasting, cost-effective power option.
Is it normal for Duracell NiMH Rechargeable batteries to become warm while charging?
Yes, it is normal for both the cells and charger to become warm while charging.
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.
Do all batteries last the same amount of time?
No, different batteries provide different lengths of life and power output depending on the type and amount of chemicals used to compose them. Think of it like cooking a meal: Using different ingredients and amounts makes the meal taste different.
Can alkaline batteries be recharged?
Only batteries that are specifically labeled “rechargeable” should be recharged. Any attempt to recharge a nonrechargeable 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.
How do Duracell batteries affect the environment?
In 1993, we voluntarily eliminated added mercury from our batteries. Our alkaline batteries are composed of primarily common materials—steel, zinc, and manganese—and do not pose a health or environmental risk in normal use or disposal. What’s more, we are going green by eliminating PVC clamshells and replacing them with high-fiber content cards and RPET (Recycled PET) blisters. This is a complete, sustainable packaging solution, one of the best PVC alternatives available today.
As the world’s leading manufacturer of high-performance alkaline batteries, we recognize our responsibility to help protect the environment. We’re committed to designing, manufacturing and distributing batteries in a way that minimizes impact to the environment. We also participate in the Call2Recycle program to ensure the safe and proper recycling or disposing of batteries.
