6.1.2 Boost Charging

Principles
Boost charging helps to rapidly restore battery capacity after the AC power supply is restored.
After long-time float charging, batteries suffer great loss caused by self-discharge and their
activity deteriorates. Boost charging is required to restore the battery activity and capacity.
The boost charging voltage is higher than the float voltage.
