Visual checkIf any breakage, leakage or deformation, the battery pack should be isolated, photographed and replaced. By quartersVisual checkClean the exterior with cotton cloth. Be careful when cleaning because the voltage is very high. Connection statusCheck each terminal to see if the bolts are loose and tighten again. Complete charge/dischargeCar Perform a complete charge and discharge cycle Warranty Regulations We is not liable for any damage to the EnerSmart-Li battery caused by force majeure (such as earthquakes, volcanic eruptions, mudslides, lightning strikes, fire and wars). We will not be liable for any damage to the EnerSmart-Li battery caused by the following events: 鈼?The EnerSmart-Li battery is damaged, broken, or leaks due to misoperation or incorrect the EnerSmart-Li battery connection. 鈼?The customer does not recharge the EnerSmart-Li battery in time and the battery are stored more than six months longer than the storage term, which causes capacity loss or irreversible damage to the聽 battery. 鈼?After the EnerSmart-Li battery are installed and connected to the system, the customer does not power on the battery in time, which causes the battery to be over discharged and further causes damage to the battery. 鈼?Damage is caused to the battery because of timely acceptance failure due to customer reasons. 鈼?Damage is caused to the battery because the operating environment or external power parameters do not meet operating environment requirements. For example, the ambient temperature is poor, power outage frequently occurs in the power grid, the battery are frequently over discharged due to the customer's improper maintenance, the capacity of a customer site is expanded, and the battery are not fully charged for a long period. 鈼?The customer changes the battery use scenarios without notifying our company. 鈼?Damage to the battery is caused by the customer or a third party. For example, the customer relocates or reinstalls s without notifying our company. 鈼?The customer does not correctly set operating management parameters including but not limited to聽 capacity, number of the battery, equalized charging voltage, float charging voltage, charge current limit, and disconnection voltage. 鈼?The customer does not service the battery based on the appropriate operation guide. For example, the customer does not periodically check whether terminal screws are tightened. 鈼?The customer connects extra loads to the battery. 鈼?The battery are stolen. 鈼?The battery warranty expires.EnerSmart-Li Battery Pack made in China website:http://www.coslinkess.com/site-ess/enersmart-li-battery-pack/
