Repair Nicd Batteries.
Repairing the memory in a Nickel Cadmium (NICD) battery will revive dead rechargeable NICD batteries. As NICD rechargeable batteries are used and recharged, crystals build up within the battery blocking the ability of the battery to hold a charge. Resetting the memory in NICD batteries is a process in which NICD rechargeable batteries are "jumped" similar to that of a car battery to remove the crystal build up, allowing the battery to work like new.
Instructions
Repair Nicd Batteries.
1. Check the NICD rechargeable batteries using the battery tester to determine if they have been fully discharged. If there is some life in the NICD rechargeable battery, continue to use it until the charge has been fully depleted.
2. Determine the negative end and positive end of the NICD rechargeable battery. The positive end will be raised and the negative end is flat.
3. Connect the black alligator clamp on the 12 volt battery charger to the negative end of the dead NICD rechargeable battery.
4. Bring the red alligator clamp up to the positive end of the battery and tap it lightly two or three times. As the battery is repaired, it may emit some sparks.
5. Complete the repair by holding both the black and red alligator clamps on the negative and positive ends of the NICD battery for a maximum of 2 to 3 seconds.
6. Release the clamps and retest the NICD battery with the battery tester. If the battery memory has not been fully reset, repeat the repair process.
