Frequently Asked Questions

Is my battery fully charged right out of the box?

No. You should charge the battery for at least the recommended charge time in user’s manual before you use your new cordless tool.

How can I improve the total life battery?

If no permanent damage has been done to your battery, you may be able to optimize its total life by following these steps:

  • Discharge the battery under normal use, and remove the battery when you feel a loss of power from the tool.

  • Let the battery sit out of the battery charger for at least two hours until the battery is at room temperature.

  • Place the battery in the charger for the recommended charge time in user’s manual to allow for a full charge.


Recycle Your Batteries

Collecting and recycling rechargeable batteries is an important part of responsible tool ownership – and in some states, it’s the law.

  Different Technologies For Different Tools

Nicad Battery Nickel Cadmium

The approximate run time on a fully charged Nickel Cadmium (NiCd) battery is 15-20 minutes and actual performance may vary based on usage.

  • Under normal household use, the useful life of an 18V NiCd battery is 150-200 full charge cycles before the user will feel that the battery should be replaced.
lithium BatteryLithium Ion

A Lithium Ion battery that is not being used will hold a charge for up to 500 days between use, but will need to be recharged before use after that time. Battery life may vary depending upon factors included but not limited to charging conditions, battery maintenance, storage and environmental conditions.

  • Holds a charge up to 500 days between use.

  • 25% lighter than NiCd.

  • 34% smaller than NiCd.
Lead SealedSealed Lead Acid

Sealed lead acid batteries are used with a product that consumes a lot of energy and weight is not a major factor. Recharging is somewhat slow and takes several hours for a full charge. Battery life is around 150 recharges and needs to be charged after every use.

  • Heavy-duty power & performance.

  • Increased run-time as compared to other battery types.

  • The battery is completely sealed and can be stored or charged in any position.

  • Stop using your battery as soon as you feel or hear a substantial decrease in power from the tool. Completely draining a battery may damage it.

  • Charge and store your battery in a cool, dry location – ideally 40°F-70°F (see your user’s manual)

  • Avoid using batteries below 32°F and above 105°F

  • The optimum temperature range for charging batteries is 40°F- 85°F.

  • Recharge for at least the recommended charge time in user’s manual after an extended period off the charger.
