- Apply the high-voltage pulse to the battery, following the recommended settings and duration.
- Once the zapping cycle is complete, try charging the battery using a standard charger.
The Equalization Charge Method
The equalization charge method involves applying a controlled overcharge to the battery to balance the voltage across all cells. This method requires a charger with an equalization mode.
To try the equalization charge method:
- Connect the charger to the battery, following the manufacturer’s instructions.
- Set the charger to equalization mode and let it perform the equalization cycle, which can take several hours.
- Once the equalization cycle is complete, try charging the battery using a standard charger.
Safety Precautions When Reviving a Dead Drill Battery
When attempting to revive a dead drill battery, it’s essential to take safety precautions to avoid:
Risks of explosion or fire: Always follow the manufacturer’s instructions when charging or reviving a drill battery. Avoid overcharging or applying excessive voltage, as this can cause the battery to explode or catch fire.
Risks of electrical shock: When working with electrical devices, always ensure you’re well-insulated and avoid touching any metal parts.
Risks of physical injury: Be careful when handling batteries and electrical devices, as they can be heavy and may cause injury if dropped.
