Those are devices whose task is to charge the cell. The charging parameters are dependent on a type and capacity of the battery. The most important parameters which must be considered while selecting a charger:
- type of battery,
- capacity,
- maximum charging current,
- voltage,
- temperature.
Battery chargers are used to charge nickel-cadmium (NiCd), nickel-hydride (NiMH), gel, AGM and lead-acid batteries. Our chargers have systems for automatic adjustment of the charging current so that the  cells are protected against overload. After the charging process the charger system goes into standby state buffering the cell. In this state the charger makes up the energy losses due to self-discharge of the battery.
