Frequently Asked Questions

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 make the meal taste different.
Do Duracell rechargeable battery chargers shut off when charging is complete?
Duracell chargers switch to a trickle charge when the normal charge is complete. You should
unplug your charger when charging is complete or when it is not in use.
Do I have to change all the batteries at the same time?
We do recommend changing all batteries in a unit at the same time. A partially used battery will
drain energy from a new one, reducing the total amount of battery power available.
Do your batteries contain mercury?
No, all versions of Duracell batteries are mercury-free. We are proud to have voluntarily stopped
using mercury in our general purpose batteries (AAA, AA, C, D, and 9V sizes) in 1993. Our
alkaline batteries are made mainly from common metals steel, zinc and manganese and do not
pose a risk to health or the environment if they are used and disposed of appropriately. All
hearing-aid batteries have been mercury-free since January 2011, in line with The Mercury-
Containing and Rechargeable Battery Act.
Does it matter what type of battery I use in my device?
Always replace the battery or batteries in your equipment with the size and type specified by the
manufacturer. Alkaline batteries are often recommended for best performance because zinc
carbon batteries have inferior life spans and equipment may not operate properly if zinc carbon
batteries are used.
How can I get a better life out of my batteries?
Here are a few tips to help extend the life of your batteries. – Turn off battery-operated radios
and appliances when they’re not in use – Remove batteries from devices that won’t be used for a
while – Store your batteries in a dry place at normal room temperature without the contacts
touching
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.”
