Maintenance-free Lead Acid Battery

Maintenance-free Lead Acid Batterynormal AGM   

 Features:

lMaintenance-free: There is no need to replenish with water thanks to the unique gas recombination system which totally transforms the generated gas into water.

lNo free acid: The special electrolyte retentive separators firmly hold the acid and thus there is no free acid inside the battery, and therefore the battery can be mounted in any position.

lExplosion-proof: A safety valve and special filter prevent the chance of battery explosion and ensure complete safety in normal use.

lLong design life: float service for 5 years.

 Discharge Characteristic

 

Temperature has big influence for battery capacity. If temperature drops, the capacity drops too.

 Charge Characteristic:

Current limited and constant voltage charging method must be used in order to keep the water in the battery circularly used and prevent water loss. The beginning charging current is usually within 0.1C~0.3C (A), and ‘C’ is the nominal battery capacity. It charges with constant current at the first charging period, then the voltage goes up. When the charging voltage reaches the setted constant value, the charging current will drop, but the voltage will keep the same.
