ACS battery chargers ensure automatic and safe charging of sealed lead acid batteries and comply with the general charging specifications indicated by all major producers. The charger operates in two steps: the first step of deep charge, the second of trickle charge. This method guarantees a deeper charge retention and consequently better performance of the battery. After connecting an ACS battery charger to a fairly low battery there are two distinct working phases:
- Deep charge -
During this first step, the unit supplies a constant flow of current while the voltage increases proportionally to the return of capacity in the battery. Once a voltage value of approximately 2.45V per cell (14.7V for a 12V battery) is reached, the deep charge mode automatically shifts to trickle.
- Trickle charge -
In this mode the charger supplies a constant voltage of about 2.3V per cell (13.8V for a 12V battery) and allows the battery to absorb only the minimum current needed to compensate its own self-discharge. During this phase it is important that the trickle voltage is stbilized and does not execeed 2.3V per cell to avoid premeture ageing of the battery. Charging mode on the unit is shown by two LEDs: the green LED indicates that the mains connected while the yellow LED is on during the deep charge and off in trickle mode. Various protection systems have been planned to improve safetely at high level:
- electronic max current limitation;
- continuous output reversal polarity protection;
- continuous short-circuit protection.
ACS chargers are made in conformity with EEC standard specifications.
