Recommend long-term storage temperature is 15 C -25 C. During storage, please recharge the battery in accordance with the following table: Storage Temperature Recharge Frequency Charging Duration -20 C - 40 C Every 3 months Do a charge and discharge cycle, the battery charge storage 5.2. Maintenance The battery system operates with hazardous voltages. Only qualified maintenance personnel may carry out repairs. Even after the unit is disconnected from the mains, components inside are still connected to the battery cells, which are potentially dangerous. Before carrying out any kind of service and/or maintenance, disconnect the batteries and verify that no current is present and no hazardous voltage exists at the terminals. Only persons who are adequately familiar with batteries and with the required precautionary measures may replace batteries and supervise operations. Unauthorized persons must be kept well away from the batteries. Verify that no voltage between the battery terminals and the ground is present before maintenance or repair. In this product, the battery circuit is not isolated from the input voltage. Hazardous voltages may occur between the battery terminals and the ground. Batteries may cause electric shock and have a high short-circuit current. Please remove all wristwatches, rings and other metal personal objects before maintenance or repair, and only use tools with insulated grips and handles for maintaining or repairing. When replace the batteries, install the same number and same type of batteries. When replace the parallel batteries, make sure the new battery is full charged. Do not open or destroy batteries. Escaping electrolyte can cause injury to the skin and eyes. It may be toxic. Please replace the fuse only with the same type and amperage in order to avoid fire hazards. Do not disassemble the battery system. 6
