B2-2.3 Charging
-
-
-
-
-
When charging, only DC can be used. Con-
nect the battery with proper charger for
specification and size to avoid overload of
circuit and interface, and to avoid electrolyte
foaming, leading to swollen battery;
The charger purchased separately must be
checked by the after-sales service depart-
ment of our company before it can be used;
When connecting the battery with the charg-
er, the circuit switch should be at “OFF”
position, make sure the connection is correct.
It is prohibited to connect the battery with live
charger.
Before charging the battery, the charging spa-
ce should be ensured with good ventilation
without open flames and combustibles;
when the temperature of electrolyte exceeds
40 degrees during charging, reduce the
current or take physical cooling measures,
the charging must be stopped when the
temperature reaches 45 degrees;
When the battery voltage remains constant
(for more than 2 hours), and the load voltage
of the battery is within the specified range
between 20.8V~24.4V, it indicates that the
charging is completed.
Daily Maintenance
-
Compared to lead-acid batteries, mainten-
ance-free battery eliminates the maintenance
to electrolyte.
B2-3 Maintenance & Care
-
-
Charge the discharged battery;
Visual inspection for excessive dirtiness and
mechanical damage after the charging.
Supplementary Charging
-
-
If the vehicle is not used for more than two
months, supplementary charging must be car-
ried out to the battery to prevent permanent
battery damage;
Charging method is in accordance with the
requirements of normal charging.
How to tell if the battery is normal?
General diagnostic method for the quality of
battery is to fully charge the battery with good
charger, and then measure the load voltage with
a multimeter to check if the voltage is between
20.8V~24.4V.
