7. Maintenance
(1) Maintenance of the Battery
a. The temperature of the battery shouldn't be higher than 50
℃
whenever it is.
b. Keep the terminal of the battery and the environment clean and dry. Be sure to mop the
dust or liquid on the battery whenever there is any. (Note: it's necessary to keep the top
of the battery clean and dry because dust or humidity could be electric conduction).
c. Be sure to check the connection between the charger and the battery before charging.
Check the condition of the poles and the wires. Make sure the terminal brackets at the
battery side are installed correctly.
d. Fully charge (charge battery over 12 Hours) the battery when battery isn't used exceed 3
months.
e. Note whether the battery is too old (can not charge the single battery over 13.5 Voltage)
or dead (the capacity of the battery drop dramatically). It will be dangerous if doing the
charging process on an old/dead battery because the temperature of the battery will rise
while charging.
f. When the battery is dead, both batteries need to be changed at the same time.
g. How to replace the battery:
Note: Take care about the procedure when changing battery or will caused short
circuit easily.
(i) Connect the Battery wire connection. The longer wire (with black and red wires),
connect the black wire to the negative pole of the battery, and the red wire to the
positive pole of other battery. Make sure each part is connected correctly and
firmly. (refer to the illustration). As to the shorter wire is to connect the positive
and negative pole of the battery (when loosing the wire from battery should be
reverse-loose short wire before longer wire).
(ii) Put grease on each and every pole to avoid pitting. The pitting will influence the
charging/discharging efficiency, and also dangerous.
