STARTING AND CHARGING( - BATTERY 20-9

BATTERY

USE AND MAINTENANCE

1 . Charging device
WARNING

DC power supply must be used for battery charging. But power plant generates AC,
which should be transformed into DC before charging.

(a) Rectifier.
(b) Controllable silicone voltage regulation charger.
2 . Charge precautions
(a) Battery should be charged in a dry and ventilated room with indoor temperature at 5
to 40 degree Celsius.
(b) Battery can not be placed on another one. Neither should it be placed on the ground
directly. It should be put on the wooden support, and cannot be placed with alkaline
20
battery or other chemicals.
(c) Charging field should be far away from fire and heat.
(d) Liquid temperature should not exceed 45 degree Celsius. Otherwise cooling measures
should be taken (by reducing filling current or stopping charge or being cooled down
in water tank).

3 . Charge connection.
(a) The positive pole of charger is to be connected with the positive pole of battery, while
the negative pole of charger should be connected with the negative pole of battery.
Never connect them reversely.
(b) Charge of most batteries may be determined based on the size of motor power.
Connection for charge must be firm.

4 . Charging modes
(a) Constant current charge, constant voltage charge and quick charge.

5 . After charging, check whether the battery capacity is restored to standard with
the voltage mode display state.

(a) Voltage method

Voltage Determination Treatment
Above 12.5V Normal Go on using

11.5V - 12.5V Undercharge Additional charge
Below 11.5V Over-discharge or internal failure To be further checked after charging

6 . Using and maintenance of battery in winter.
(a) Keep the battery fully charged to avoid the electrolyte from being frozen arising from
drop in density, which may give rise to breakage of container, curve of pole plats, as
well as smash and dropout of active substances, and other failures.
(b) Because the battery capacity is reduced in winter, when starting the engine in cold

status, preheat the it. And each time starting the engine should not more than 15
seconds. Interval of two startings should be 2 to 3 minutes. If engine could not be
started in three times, troubleshoot it and then restart it.
