Low voltage battery maintenance

Checking low voltage battery

Frequently check the battery surface and the positive and negative terminals, ensuring that the positive and negative terminals of the battery are not loose or corroded.

Check the appearance of the battery for cracks, swelling, etc. If there is the above symptom, it is recommended to contact GAC Service Center for repair as soon as possible. For more inspection and maintenance items, please refer to the "Maintenance instructions - Regular maintenance" section in the Warranty Manual.

Replacing low voltage battery

Always use the battery of the same type and specification to replace the battery. It is recommended to contact the GAC Service Center to remove, replace or install the battery.

Environmental protection:

◆ The recycling of the battery must be carried out by a qualified unit to avoid pollution to the environment and damage to the operator.

Vehicle storage

Due to natural discharge and the wear- out effect of certain electrical consumers, the power stored in the battery is gradually depleted even when the vehicle is not in use. If the vehicle is not in use for a long time, the battery power may be exhausted and the vehicle may fail to be started. Therefore, the negative terminal of the battery should be disconnected, and the battery power should be checked regularly. If necessary, start the vehicle to charge the battery.

WARNING

◆ Do not attempt to start your vehicle by jumper cables and low voltage batteries from other vehicles. If the jumper cables are connected or disconnected in the wrong order, an electrical short circuit may occur, resulting in vehicle damage or injury, and the consequent repairs are not covered by the warranty. ◆ When removing the battery terminals, be sure to remove the negative terminal first. If the positive terminal is removed and it touches any metal in the surrounding area, it may spark and cause a fire, and possibly an electric shock, resulting in serious injury or even death.

◆ Before reconnecting the battery, turn off all electrical consumers on the vehicle. Connect the positive terminal first and then the negative terminal. Never install the terminals in the wrong order, as there will be a risk of fire.

◆ The battery shall be kept away from heat sources and open flames, and ventilation shall be maintained during charging and use, otherwise it may cause fire or personal injury.

◆ Always check whether the battery terminal clamps are firm and in good contact to avoid sparks and battery explosions.

◆ The hydrogen gas generated when the battery is charged is flammable and explosive, so when using a charger to charge the battery, be sure to remove the battery.

◆ Always wear safety goggles when working on the battery and be careful not to let any battery electrolyte come into contact with your skin, clothing or body.

◆ If the battery electrolyte comes into contact with your skin or eyes, rinse immediately with water and seek

WARNING (Cont’d)

medical attention. The contact area shall always be covered with a damp sponge or a piece of damp cloth until you see a doctor. ◆ Always wash your hands after working on the battery bracket, terminals, and other battery-related parts.

◆ Do not lean over the battery.

◆ Keep children away from the battery.

◆ Do not charge a battery with a bulging, cracked, or leaking acid casing. ◆ Do not charge a battery with a voltage lower than 10.5V when the temperature is below 0°C. If charging is necessary, move the battery to a room temperature (25°C) environment and let it sit for 24 hours before charging. ◆ If external charging is required, use a 12V lead-acid battery-specific charger and follow the operating instructions. Do not charge at high voltage for an extended period (AGM battery charging voltage must be ≤14.8V). ◆ Do not hit the terminals to avoid loosening, which could cause acid leakage or spillage.

CAUTION

◆ Avoid battery overcharging or long- term power loss.

◆ Avoid long-term high-current discharge of the battery. ◆ Avoid prolonged use of electrical equipment when the vehicle is not started, which may cause the battery to lose power. ◆ Firmly install the battery on the vehicle to avoid vibration. ◆ The oxides and sulfates produced by the battery terminal clamps must be cleaned up, and Vaseline shall be applied to avoid re-corrosion.

CAUTION (Cont’d)

◆ When the vehicle runs in a cold region, do not discharge the battery completely to avoid freezing of the battery electrolyte.

◆ When driving in cold regions, do not allow the battery to fully discharge to avoid the electrolytef freezing.

◆ Do not randomly install electrical devices to prevent long-term battery discharge and sulfurization, which shortens the battery's lifespan.

◆ The battery terminals and connections to the wiring harness must be tightly secured and have good contact, otherwise, charging speed will slow down, and battery aging will accelerate. ◆ It is recommended to regularly check that the exhaust holes on both sides of the battery cover are clear. Do not allow dust, ice, or water to block them to prevent poor ventilation. ◆ If the battery becomes discharged for

any reason during use, charge the battery promptly to prevent long-term discharge, which accelerates aging.

◆ When using metal tools for assembly or repair, do not connect them directly to the positive and negative terminals to avoid reverse connections, short circuits, or loose wiring that could damage the battery.

◆ Due to the decrease in temperature, the battery's discharge capacity and charging speed are reduced, so extra care should be taken to minimize battery discharge. If you are in an extremely cold area and have a warm storage facility, it is recommended to store the vehicle in a heated garage.

NOTE

◆ If the vehicle's power is on but the engine is not started, prolonged use of electrical devices in the car will cause the battery to discharge quickly. When leaving the vehicle, ensure the doors are closed and all electrical devices (such as lights) are turned off.

◆ If you have no plans to use the vehicle for more than 30 days, it is recommended to fully charge the battery and disconnect the negative terminal (except for 12V lithium batteries) to prevent over-discharge. If the vehicle has not been used for over 180 days, it is recommended to start the vehicle or use a dedicated charger according to the instructions to charge the battery. ◆ If the vehicle is used for long periods of short trips (less than 10 minutes), it is recommended to perform a vehicle start operation for at least 30 minutes once a month. ◆ If the 12V low-voltage power supply system fault indicator light is on after repairs or remote software upgrades, please start the vehicle or use a dedicated charger according to the instructions to charge the battery.

◆ Please follow the battery usage and maintenance precautions; otherwise, it may lead to early battery replacement and affect warranty coverage. If the battery appears in good condition and the usage and maintenance instructions have been followed, but product issues arise, please contact the GAC Service Center dealership for warranty service. If the battery issue is due to incorrect usage, it will not be covered under warranty, but GAC Brand will provide necessary technical support and services.

Maintenance of traction battery

Precautions for use and maintenance of traction battery

DANGER

◆ It is strictly forbidden to remove, disassemble or modify the traction battery, or use the traction battery for other purposes. ◆ The traction battery shall be placed out of the reach of children. ◆ The traction battery shall be kept away from fire sources to avoid fires or explosion. ◆ It is forbidden to spray, trample, hit or destroy the traction battery to avoid leakage, fires or explosion of corrosive chemicals. ◆ It is strictly forbidden to touch the positive and negative poles of the traction battery case with both hands at any time. ◆ It is strictly forbidden to perform operations such as squeezing, piercing or burning that damage the battery system for the traction battery. ◆ If the traction battery suffers severe mechanical damage, resulting in the exposure of internal high-voltage components, there is a risk of violent combustion and electric shock, which may cause serious casualties and environmental pollution. ◆ The traction battery damage or electrolyte leakage may cause a fire. If it happens, it is recommended to contact the GAC Service Center immediately. Do not touch the leaked electrolyte with hands. If the skin or eyes come into contact with the electrolyte accidentally, rinse the skin or eyes immediately with plenty of water, and seek medical attention immediately. ◆ Since the traction battery pack is a high-voltage component, it is strictly prohibited to open or repair the traction battery pack by non- profession.
