Battery Care

To prevent battery shorting, leakage or rupture:

  • Never dispose of batteries in fire, as they could explode.
  • Do not attempt to recharge a battery unless the battery specifically is marked "rechargeable."
  • Do not store batteries loosely or carry them loose in your pocket or purse – they can be shorted, leak or rupture due to contact with metal objects.
  • Remove worn-out batteries from equipment immediately.
  • Always keep batteries out of the reach of young children.
  • Always replace all batteries at the same time. Mixing old and new batteries or mixing types (such as alkaline with zinc carbon) will reduce overall performance and could cause leakage or rupture.

Follow the easy battery care tips below to get the most out of your DURACELL Batteries:

  • Use the correct size and type of battery specified by the manufacturer of your device.
  • Keep battery contact surfaces and battery compartment contacts clean by rubbing them with a clean pencil eraser or a rough cloth each time you replace batteries.
  • Remove batteries from a device when it is not expected to be in use for several months.
  • Remove batteries from equipment while it is being powered by household (AC) current.

Battery Disposal Instructions - Europe

The disposal of all types of single use and rechargeable batteries in Europe is regulated under EU law. Amongst other things this requires manufacturers and importers of batteries to pay for the collection and recycling of their batteries when they are spent. In all countries collection boxes, where consumers can dispose of their used batteries, are available in retail stores that sell batteries and also at municipal waste collection sites; in some countries collection boxes are also placed at schools and other public buildings.

In all countries Duracell has joined a battery collection and recycling organization that operates to a high professional standard to makes sure that all the collected batteries are transported, sorted and recycled in full accordance with the legal requirements.

Professional users of batteries are advised to set up in-house collections of used batteries in collaboration with a collection and recycling organization who will periodically take them, free of charge, for recycling.
