How to Keep Batteries from Leaking in a Flashlight


You grab your flashlight and turn it on, but all you see is darkness. When you open up the battery compartment, you immediately see the problem--the batteries have leaked. Batteries that leak in a flashlight make a mess. If the leak is small and caught right away, it can probably be cleaned up, and the flashlight can be saved. Larger leaks can easily ruin the flashlight. This is a common problem you can avoid by using some smart tactics.

Things You'll Need

  • Battery tester
  • Remove the batteries from a flashlight that is rarely used. You can store the batteries along with the light, but don't install them until you are ready to use it.

  • Leave the batteries in a flashlight that you have placed in a glove compartment or other place to use in case of an emergency. Remove, inspect, and test the batteries at least every 6 months. If the batteries are run down, immediately replace them. Depleted batteries are more likely to leak.

  • Replace depleted batteries in a flashlight with fresh, new ones. Don't mix old and new batteries. Use batteries that are the same type, made by the same manufacturer.

Tips & Warnings

  • All flashlight batteries can leak if they are not taken care of. However, name brand batteries have a better track record when it comes to holding up better than cheap batteries.
  • Store batteries in a cool, dry place.
  • Read the manufacturer's instructions that came with the flashlight. Use the batteries that are recommended by the manufacturer.
