With assistant battery
Caution:
Avoid pushing or pulling the car to start, which may cause the damage of exhaust gas
purification system and/or other parts.
When the jumper cable is applied, carefully handle the assistant battery and the
discharged battery. Avoid spark, and observe the following steps.
Warning:
※
Any breach of the following conditions or steps may cause the following situations:
(1) Serious damage to person (especially the eyes) or materials, which result from
the explosion of battery, combustion of acid liquor of battery and the electrified body.
(2) Damage to the electronic parts of car.
Never place the battery in the place with electric spark, for the gas generated by
※
battery is inflammable and explosive.
Remove the jewelry, watch and other valuable goods, and wear protective glasses.
※
※
Prevent the liquid of battery from directly touching eye, skin, fiber and varnish,
because it is corrosive acid liquor. In case that it touches any parts, rinse them
immediately.
Take care that the metallic tools or jumper cable don't touch the positive t

erminal of
battery (or the metals connecting with it) and other metals in the car, for it may
cause short circuit.
Keep the little children away from the battery.
※
1. Pull up the parking brake and put the gear shifter to the neutral position, switch off
the igniter, lights and all other electric loads.
2. Connect one end of a jumper cable to the positive terminal of assistant battery, and
the other end to the positive terminal of the discharged battery (jump-start the engine
with 12v battery only).
3. Connect one end of the negative cable to the negative terminal of assistant battery,
and the other end to the firm engine ground cable (e.g. in the exhaust manifold),
which is at least 45cm(18in) away from the battery which starts the car.
Warning: avoid directly connecting the negative cable to the positive terminal of the

discharged battery.
4. Start the engine of the car preparing to jump-start, and switch off other electrical
equipments. And then start the engine of the car with low-battery battery.
5. The step of disconnecting jumper cable must be exactly contrary to that of
connecting. The first step is to disconnect the negative cable from the jump-started
engine.
With charging equipment
Note: As to the jump-started engine with charging equipment, the applied equipment
should be 12v, and the negative electrode should be connected to ground. Never adopt
the 24v charging equipment, for use of such equipment may cause serious damage to
the electrical system or electronic parts.

Removal and Installation
1. Disconnect the negative cable.
2. Disconnect the positive cable.
3. Remove the clamper nut and clamper.
4. Remove the battery.
5. When installing, the sequence is the reverse procedure of removal,
6. Tight the fixing nut of the battery cable according to the set torque.
Note: Check and ensure an enough distance between grounding cable and engine
cover beside terminal post.
Tightening torque: 6~10N·m
Charging the battery which voltage decrease greatly or which is fully discharged.
1. Measure the voltage of battery terminal post with the prepared voltmeter. If the
voltage is less than 10v, the charging current is very low. So there is a certain time
before the battery can accept the several-milliampere current. Such a low current
won’t be detected by the amperometer used on the spot.
2. Put the battery charger in a high pre-set place.

Charging System
3. With the polar protective circuits, some chargers won’t charge until the lead is
appropriately connected to the terminal post of the battery. The fully discharged
battery has not enough voltage to activate the whole circuit. Even though the lead is
correctly connected, the battery can’t accept charging current. So this circuit should be
bypassed according to the special regulations of the charger manufacturer so as to
switch on the charger and charge the low-voltage battery.
4. The voltages and current values provided by battery charger differ from each other.
With each voltage, the measurable charging current that can be accepted by battery
needs the following time:
Voltage: A:over 16. . . 4 hours
B:14-15.9. . . 8 hours
C:less than 13.9. 16 hours
After the above-mentioned charging time ends, if the charging current can’t be
detected yet, the battery should be replaced; if the charging current can be detected,
the battery is good, which can be charged in the normal way.
5. Always remember that only when the fully discharged battery is charged to enough
ampere hour (AH) can it be used again. According to experience, the charging ampere
hours basically equals the nominal AH plus an additional 30% of it, which is usually
used to charge the normal battery. For example, the required AH for the 45AH battery
fully charged is 45×1.3=58.5. So, you are recommended to charge with a low ampere
but for a long time. For example:
3 ampere×20 hours. . . 60AH or
5 ampere×12 hour. . . 60AH etc.
You are recommended to conduct load test to the battery recharged in this way so as
to check its operational capability.
