A rechargeable electric appliance battery can expand the memory if not used frequently or fully charged. After the battery develops memory, the battery seems to be fully charged, but when you use this tool, the battery will die within a few minutes.
1. Check your battery charger to make sure the battery can be charged properly. Check for bent branches or anything that can prevent the charger from making contact with the power outlet. Replace the charger if you determine that it is the cause of not charging the battery.
2. Use a multimeter or battery tester to "zap" a rechargeable battery. Hold the black end of the multimeter to the negative or flat battery end. Keep the handle on the negative end when you tap the red end of the multimeter to the positive or raised battery.

3. Repeat Step 2 for each rechargeable battery that you want to turn on again.
4. Insert the rechargeable battery into the charger until it is fully charged. Use in power tools or other electronic devices as usual.
5. Repeat the charging and drying process several times, and the battery will be better at holding back charging and charging fully.
6. Touch the red wire clamp to the anode battery positive drill and the black to the negative anode. Hold the clamp in place for no more than 10 seconds. After 10 seconds, drop the cable 1 foot from the battery.
7. Disconnect the cable from the car battery, roll it, and store it. Never leave jumper cables inside the element. Cover the hood of the car.
8. Insert the drill battery into your drill. It has to hold costs and start working again. This might not work for very long batteries.
