The Sigma battery charger features the most advanced pulse repair technology to improve the performance of your battery with a repair time of 4 hours and maximizes your battery's lifespan.
If you are not sure whether your battery needs to be repaired with the 12V Super Repair mode, you can try the following two ways to determine:
- Check the battery voltage.
If your battery voltage is significantly lower than the standard voltage, you may consider repairing the battery with the 12V Super Repair Mode. For example, the Sigma battery charger detects that the voltage of a 12V battery is 5V.
- Check the battery discharge rate.
If the battery is fully charged and the power drops rapidly under normal use, you may consider repairing the battery with the 12V Super Repair Mode.
Note: The voltage displayed on the screen indicates the voltage of the connected battery.
