How to Recharge AAA Batteries


Rechargeable batteries can save you time and money. By constantly having a "good" set of batteries on hand, you never have to worry about stopping what you are doing to go buy more. You can recharge AAA batteries easily with any standard charger. As long as you have a power source, rechargeable AAA batteries and a battery charger designed for AAA batteries, you will have a steady supply of power for your portable items without constantly having to buy more batteries.

Things You'll Need

  • AAA battery charger
  • AAA rechargeable batteries
  • Plug your battery charger power cord into an electrical outlet.

  • Load your rechargeable AAA batteries into the battery compartment of the charger. Make sure that the end of the battery marked positive (+) is placed in the end of the battery compartment also marked positive (+).

  • Check on the battery charge indicator light to see how the charge is progressing. The light will be a solid red while charging and turn a solid green when the charge is complete. Unless you have purchased a battery charger with an automatic shutoff when the correct voltage is reached, you should immediately unplug or remove the batteries from the charger when the light is green to prevent overcharging.

Tips & Warnings

  • Buy a battery charger with a setting for "discharge" or "recondition." This setting allows you to periodically remove all of the stored power from your batteries and recharge them (renew the battery), extending the batteries' lifespan.
  • If the charge indicator light does not come on or shows a flashing red light, one of your batteries is bad. Remove the batteries one by one until the red light is solid to determine which battery is dead.
