An electronic PC-board measures the battery temperature. The rectifier/charger uses this information to adjust the battery
charge current to the temperature in view of:
optimizing battery recharge;
obtaining maximum battery time;
ensuring maximum battery life.
Cubicles may be supplied empty, thus enabling users to make up their own auxiliary cubicles (battery cubicles or other) or
panels and meet the particular demands of each installation. In this way, the entire electrical installation will have a uniform
appearance.
