The MA series lead-acid battery charger is professional design according to the power battery of electric vehicles equipment. With short-circuited protection, low-voltage protection, over-heated protection. The long delay digital counter can ensure the battery from the constant voltage to the float charge reliably every time.


TYPE: AC to DC converter, Lead-acid battery charger
Adjustment of the charging current
Reverse battery pole + - protection
Visualized charging current by precise meter
FOUR-phase smart battery charger: pre-charge, constant current, constant voltage , Floating charge
Suitable for the water storage battery and battery without maintenance
Suitable for lead-acid battery

Protection: Overheat Protection, Short-circuit protection, Low Voltage Protection, Reverse Protection

Four charge Modes:
Pre-charge Mode: In order to protect the battery, extending battery life, when the battery due to excessive discharge or stored for a long time and cause internal resistance is too large, the voltage is too low automatic output small current to charge the battery. When the battery voltage rises to the set voltage, the charger automatically converted to constant current charging mode.
Constant Current Mode: When the battery voltage is lower than the charger voltage is set constant current charging mode, the battery charger provides constant charging current.
Constant Voltage Mode: Using pulse width modulation technology, precise control of the charger charging current and output voltages to ensure a fully charged battery is charged, to avoid overcharging.
Float Mode: When the battery voltage approaches the set voltage constant voltage charging mode, the charging current is reduced to set current time, battery power has been filled, the light turns green, the cooling fan stopped working. Charger automatically charging mode to trickle charge the float mode. The battery can be disconnected, or continue to float.
PS: The Charger is not suitable for US/Canada and so on which country is with 110V voltage! Pls note!
