2.11.2 Description and operation 

2.11.2.1 Battery Description and Operation 

Warning: Refer to "Explosive Gas Generated by Battery" in "Warning and Precautions". 

Warning 

This vehicle uses a maintenance-free battery, which is different from a conventional battery. There 
is no vent plug in this battery. Apart from a small vent on both sides of batteries, the battery is 
completely sealed. Vent holes can discharge a small amount of gas generated by the battery. The 
electrolyte inside the battery generates a small amount of gas after chemical reactions. If there is 
no exhaust vent, battery internal pressure increases as the gas pressure increases. When the 
pressure is over limit that the battery shell can withstand, the battery shell will break. 

Compared with a conventional battery, this battery has the following advantages: 

– 

No need to fill water during the life of the battery. 

– Overcharge 

protection. 

– 

Electricity leakage is less likely to happen as compared with a conventional battery. 

– 

Lighter, smaller and capacity is larger. 

In the entire electrical system, battery has main functions: 

– 

Provide energy to the starter for starting the vehicle. 

– 

Play a role as the electrical system voltage regulator. 

–  When the generator electrical system capacity can not meet the demand, the battery can 

provide power in a certain period of time. 

Explanation of battery technical parameters: 

1.  Capability: Indicating the minimum time for the battery to provide the vehicle load working 

when the charging system is inactivated at night or atrocious weather. Namely, the battery 
discharging at 25 A under 27  (80.6 

℃

°F) until the final voltage of 10.5 V lasts 145 min. 

2.  Cold-start current: Indicating the startup current that the battery is able to provide under low 

temperature. The battery with 660 A current can discharge over 30 s at the voltage above 7.2 
V under the ambient temperature of -18  (

℃

-0.4 °F). If the battery test is normal, but the 

battery voltage often appears inadequate, the vehicle can not start at night etc., consider the 
reasons from the following aspects: 

– 

Electrical equipment in the vehicle remain turned on all night. 

– 

Driving speed is low, stop and start frequently. 

– 

Electric load of vehicle exceeds output of generator, especially when the vehicle is equipped 
with after-sales optional device. 

–  Charging system fault, such as electrical short circuit, generators belt slipping, generator 

malfunction or voltage regulator malfunction. 

– 

Improper use of the battery, including failing to maintain battery cable terminals clean and 
tighten, or the battery bracket is loose. 

– 

Mechanical failure in the electrical system, such as short circuit or circuit damage. 

2.11.2.2 Start System Description and Operation 

Start system includes the battery, ignition switch, starter, start relay and related circuits, and all of 
these components are connected by circuits. When the ignition switch is turned to "ST" position,
