How to Recondition Power Tools Batteries

Power tools use batteries or electricity to function, and batteries can be rechargeable or for one-time use. Typically, they are rechargeable. Nickel cadmium, or NiCd batteries, are normally used in power tools. These can be charged up to around 1,000 times before they need replacing. Reconditioning, especially after months of no use, is very good for these batteries, and should be done about once a month throughout battery life to ensure proper functioning and optimal lifespan.

Price: AU $ 84.44

Instructions:

1. Run the battery in the power tool without any obstruction. For instance, if you have a power drill, run the drill by itself, do not try to drill in anything; just let the battery run until it's dead.

2. Plug the power tool battery charger into the electrical outlet.

3. Charge the battery back to full capacity.

4. Run the battery as before until it is dead again.

5. Recharge the battery again.

6. Repeat once a month, or if this process has not improved your battery's performance, throw that one away and purchase a new one.

Tips & Warnings:

There are other, more complicated, ways to recondition a battery. Check your owner's manual for proper care and maintenance. This may show how to recondition your battery, but more important, follow the instructions on care and maintenance to prolong its life.
If the casing is cracked and/or components of the battery are leaking/falling out, throw the battery away immediately.
