Overheating protection 

If the BatteryCharge4 becomes overheated during charging, the power output is automatically reduced. This protects against damaging both your battery and the charger.


Trickle charging 

Once the battery has been fully charged, the BatteryCharge4 automatically changes to trickle charging. Depending on the measured voltage, the charging is interrupted or the battery is maintained in a fully charged condition with low voltage currents. 


Note: A battery can remain permanently connected to the charger without damage or adverse effect on its performance. The trickle charge can be used to maintain a battery.
