All newer PowerLasers run on rechargeable Lithium Ion batteries. We use carefully selected battery cells from quality suppliers.


The lifetime of a battery, however, depends on a few factors. In our production department, we receive batteries for repair that are anywhere from 2 to 6 years old. Typical lifetime of a battery is 3-4 years.


The following are a few tips that can help prolong the lifetime of your Lithium Ion battery:

  • Use the batteries and rotate them
    Lithium Ion batteries work best when they get used regularly. Don’t set aside a battery as a ‘spare’ battery. If the battery doesn’t get used, the battery will lose its capacity more quickly.
  • Charging regularly
    It was previously said that a battery needed to be discharged completely before charging. This was true for Nickel Metal Hydride (NiMH) batteries. However, this is not true for Lithium Ion batteries that work better when they’re charged frequently.
  • Cool storage
    Cool storage prolongs the lifetime of your batteries. Avoid exposure to direct sunlight.
  • Change the battery as soon as your PowerLaser indicates low-battery
    The PowerLasers have a built-in function that signals when the battery is low. When this happens, charge the battery and use the second battery in your PowerLaser. Avoid ‘forcing’ your PowerLaser to keep going with a battery that’s low.
  • Don’t store a partially or completely discharged battery
    If you need to store a battery for a longer period of time, charge it first. Storing the battery in a partially or completely discharged state will reduce the lifetime of the battery.
