Frequently Asked Questions about Power Tool Batteries

How long should I charge my battery?
How long you charge your power tool battery depends on many factors such as how discharged the battery is. Typically an overnight charge is sufficient to charge a battery, but in some cases it can take longer. Often, most chargers have an indicator light telling you when your battery is fully charged and ready to be used.

Can I use a NiCD or NiMH battery?
If your tool currently has a NiCD battery, you can upgrade to a NiMH battery as long as your charger will accept a NiMH battery. The same goes for if you have a NiMH battery and want to switch to a NiCD battery. One of the biggest differences between these two rechargeable chemistry's is that NiMH batteries generally have a larger capacity.

How do I properly dispose of my old battery?
You can usually take your batteries to a local battery store or scrap yard to be properly disposed of.
