1、With 7‑phase charging function, 7‑phase charging, desulfurization, trick current charging, constant current charging, constant voltage charging, battery power detection. 2、Only the voltage and temperature are displayed in the detection of the phase, and the power grid effect is consistent with the recovery mode), also can charge compensation and floating charging. (There is no lithium battery in this phase). 3、With overcharge protection function, it can prevent the battery life from being reduced due to overcharge and improve reliability. Therefore, you can connect the charger to the battery indefinitely. 4、If it detects that the temperature is too high, it will automatically start the overheating protection program. When the temperature returns to normal, the initial charging state will be restored. 5、7‑level charger is suitable for most battery types and with Microprocessor Control (CPU). They can also help recycle used and sulfated batteries. Suitable for Calcium, Gel and AGM, Wet, EFB 12V 24V Ternary Lithium Iron 12V 24V Lithium Iron Battery, etc.
