If equipment must be used periodically in extreme temperatures, premium alkaline batteries are recommended. These types perform much better than zinc carbon batteries under such 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).

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.

Carefully follow instructions on your equipment regarding proper insertion of batteries, ensuring that the + (plus) and – (minus) terminals are aligned correctly. CAUTION: Some equipment using three or more batteries may appear to work properly even if one battery is inserted incorrectly; such usage may lead to battery leakage or rupture that could result in equipment damage.

Yes, it is normal for both the cells and charger to become warm while charging.

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.

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.

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

If equipment must be used periodically in extreme temperatures, premium alkaline batteries are recommended because they perform much better than zinc carbon batteries under such conditions.

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.

Batteries should be removed from devices/equipment when:

• The device is not expected to be in use for several months
• The batteries are worn out (to prevent possible damage from battery leakage)
• The device is being powered by household (AC) current

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.

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.

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

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.

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 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.
