    Boost charging starts when the switch-on threshold is reached. Boost charging can also be started manually. Boost charging stops after the charge duration has expired or when the charge completion voltage has been reached, whichever happens first. With boost charging the charging voltage is higher than with float charging. After boost charging the controller automatically switches to float charging.
