Automatic charging can prevent the battery from overcharging. So you can let the charger connect to the battery indefinitely.

Better performance: Level 5 charging is a very comprehensive and accurate charging process. Compared with using traditional chargers, it enables longer battery life and better performance.

Compatible: The 5-level charger is suitable for most battery types such as calcium, gel, AGM, and wet batteries. They can also help restore exhausted and sulfated batteries.

1. Desulphation
The Desulphation stage may break down sulphation that occurs in batteries that have been left flat for extended periods of time, returning them back to full charge. sulphation occurs when lead-sulphate hardens and clogs up the battery cells.
2. Bulk (Constant Current)
Bulk mode charges the battery at the maximum rate (constant current) putting a large amount of power into the battery in a short amount of time. This stage will charge the battery to approximately 60%, until the voltage reaches 14.7 volts for 12V charger
3. Absorption (Constant Voltage)
The charge rate slows down so the battery can absorb more power and reach 80% charge. The voltage remains at a constant 14.7 volts for 12V charger while the current is gradually reduced until no more power can be added without over-charging the battery.
4. Float
The Float stage maintains the battery at 100% charge without overcharging or damaging the battery. This means the charger can be left connected to the battery indefinitely.
5. Stop-The Charger stop charging and cut-off output.
