(1) Battery pack storage

The storage temperature is 0°C~40°C (the best storage temperature is 15°C~25°C, dry storage). The performance of the battery pack is affected by the temperature. The most intuitive performance is the change of the battery pack capacity, which is a normal phenomenon.

Avoid condensation caused by temperature changes during storage, otherwise it will cause rusting of batteries or metal parts.

(2) Check the battery pack before use

● After receiving the battery pack, first carefully check the packaging for any abnormality, and avoid impact during transportation.

● Check whether the battery pack casing and accessories are damaged, leaking or missing. If there is any damage or missing, please contact our company.

● Check whether the charging and discharging terminals of the battery pack are correct, whether the positive and negative poles are reversed, and whether the voltage is within the normal working voltage range of the device. If there is dirt or rust on the terminals, wipe them with a dry cloth before use, otherwise it may cause poor contact of the electrode terminals.

(3) Precautions for battery pack installation

● Clean the installation location of the battery pack to ensure that there is no dust, metal foreign matter or other foreign matter. Fireworks are strictly prohibited during the installation process to avoid short circuit of the battery pack and prevent equipment damage or personal injury.

● The battery pack is in place, and the battery pack is placed at the installation location. The battery pack should be installed in a well-ventilated, dry and clean environment. The battery pack should not be installed in a place that may be immersed in water. The battery pack should be used and stored away from close proximity. Flammable and explosive items.

● The battery pack and the compartment should be damped and fixed to avoid mechanical damage to the battery pack.

● Tighten the terminal of the electric wire on the terminal of the battery pack. Do not use excessive force or exceed the specified torque when tightening, otherwise the terminal may be damaged.

● After the installation is complete, check whether the terminals are fastened in place and whether there is any debris on the surface of the battery pack. Use a dry cloth to clean the outer packaging of the battery pack.

Use tools that are prone to static electricity to clean the outer packaging of the battery pack. Do not use organic solvents such as volatile oil, otherwise it will damage the outer packaging of the battery pack.

Packing even cracks the outer packaging of the battery pack.

● Take care to ensure that the positive (+) and negative (-) polarities of the terminals are connected correctly. Otherwise, it may cause fire or damage to the battery pack and electrical appliances.

damage.

● Test the equipment and observe whether the equipment and battery pack are abnormal.

(4) Daily maintenance of battery pack

● The battery may be over-discharged due to its self-discharge characteristics if it is not used for a long time. In order to prevent the occurrence of overdischarge, the battery should be regularly charged and discharged to maintain its voltage within a certain range (13.2V). The battery pack shall be charged and discharged at least once within 3 months (the battery pack with communication function shall be charged and discharged at least once within a month, and the SOC/capacity calibration needs to be calibrated. The calibration method is to use the charger to fully charge the battery pack and discharge it until the battery pack is protected. .

● Do not use organic solvents to clean the battery pack case.

● The battery pack is a consumable item with a limited lifespan. When the capacity of the battery pack is lower than the usage requirements, please replace the battery pack in time to avoid losses due to insufficient capacity.

● In order to prevent the safety problems caused by the failure of the overcharge protection function of the protection board, do not charge for a long time. Take out the battery after it is fully charged. In addition, you must use the original charger or the charger attached to the battery when charging, and operate and use according to the instructions. , otherwise the battery may be damaged or even dangerous.

● Shallow charging and shallow discharging of the battery can ensure the economical use of the battery pack. Overcharging and over-discharging may cause the battery pack to overheat, catch fire or fail to function, shorten its life, or even be dangerous.

● The switch of the battery pack, the power display board, and the input/output interface are lossy parts, and paid after-sales service can be provided. Lithium batteries at the end of their life should be recycled and disposed of in accordance with local laws.
