Smart chip with memory function

The charger is equipped with a smart chip with memory function. After plug in the charger is in the mode that has been set previously.

Detection of batery damage

After plug in the charger is capable to detect battery damage or incorrect pole connection. In such cases it doesn‘t start to charge and LED indicator lights up.

Automatic recovery

The mode is designed to recover deeply discharged battery and cannot be set separately. After plug in charger automatically detects deeply discharged battery and starts to charge by using a lower current. Once the battery pack reaches the normal voltage charger continues in standard charging manner. The maximum duration of the recovery mode is 20 minutes. If the proper voltage is not reached within this time charging is automatically interrupted and the battery is treated as damaged. Warning LED indicator lights up imminently.


Při procesu automatické desulfatace nabíječka nejprve zjistí stav akumulátoru. Pokud akumulátor vykazuje vlastnosti, které jsou typické pro sulfataci, spustí proces rychlých změn napětí tzv. "pulzování". Nabíječka tím z elektrod odstraňuje krystaly síranu olovnatého.
