Can I use batteries underwater or in other vacuum conditions?

No, Duracell batteries are not designed to be used underwater or in vacuum conditions. The cells are designed to be used under normal atmospheric conditions and in fairly constant temperatures (approximately 21 °C/70 °F).


Are batteries affected by temperature?

We recommend storing batteries at room temperature in a dry environment. Extreme heat or cold reduces battery performance. You’ll want to avoid putting battery-powered devices in very warm places. In addition, refrigeration is not necessary or recommended.


Which way does the + and – go?

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.


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


Which battery type should I use in extreme temperatures?

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.


When should I remove batteries from my device?

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.


Does it matter what type of batteries I use in my device?

You can only recharge a battery if it’s specifically marked “rechargeable.” Recharging a non-rechargeable battery may cause it to rupture or leak and may cause personal injury.


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.


Can I mix old and new batteries?

Do not mix old and new batteries. Doing so will reduce overall performance and may cause battery leakage or rupture. We recommend replacing all batteries within a device.
