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?

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.

Which battery type should I use in extreme temperatures?

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.

When should I remove batteries from my device?

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

Does it matter what type of batteries 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

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.
