Victron Automotive IP65 Charger 12V/4A-12V/0.8A

Victron automotive battery chargers are designed to be able to leave connected to the battery all the time. The charger will drop its voltage to a storage mode (13.2V) whenever the battery has not been subjected to a discharge during a 24 hour period. Once a week the charger will raise the voltage to absorption level to equalize the battery. This feature prevents stratification of the electrolyte and sulphation major causes of early battery failure.
