Things Not To Do

Battery Care and Safety

Battery Life

Don't forget to check that the batteries you are throwing away are really dead! Undischarged batteries may cause damage when placed in waste. 

To take full advantage of your batteries, please go through the following steps:  

  • Have you followed the instructions for battery installation on the device?
  • Have you made sure the batteries are correctly aligned?  Make sure the + and - terminals are in line with the instructions.
  • Have you checked that the batteries connections are clean?  Clean the terminals if in doubt.
  • Have you checked that your batteries aren't too cold?  They don't work well in the cold.
  • Don't mix the battery types.  You'll lose the charge on the better ones.
  • Once your old batteries are dead, remove them immediately.  This helps prevent corrosion.

Preventing Leakage
Battery leakage is the in-built safety device to prevent something worse from happening.  Here's how to help avoid it:

  • Promptly remove dead or weak batteries from devices
  • Never mix old and new batteries in a device. Battery leakage may occur.
  • Replace all batteries in a device at the same time.
  • Never mix battery types in a device. Battery leakage may occur. Examples of battery types are alkaline, carbon zinc, rechargeable NiMH, zinc-air, lithium metal and lithium-ion.
  • Remove batteries from any device that will be stored for long periods of time.
  • Do not leave battery powered devices switched "on" after the batteries are exhausted; battery leakage may occur.


  • Store batteries in a cool, dry location. Avoid direct sunlight exposure.
  • Remember, batteries are like any other chemical system. Heat will accelerate the chemical reaction and shorten cell life. Avoid storing batteries or battery-operated devices in extremely warm places or other temperature extremes.
  • Keep batteries in their original package until you are ready to use them.
