A battery is consist of the anode, the cathode, the electrolyte, the diaphragm and the container. It converts energy by oxidation - reduction reaction. View>>

Battery is a device used to converse and store chemical energy. It can convert chemical energy into electrical energy. View>>

Battery quality problems and improper use can make its actual capacity decrease and its internal resistance increase, and even may cause serious accidents, endangering the normal operation of UPS and the normal functions of uninterrupted power. View>>

Although maintenance-free batteries don't need special maintenance work, there are still some requirements. View>>

1. Batteries should be placed upright, and using batteries upside down is prohibited; 2. Do not give the battery abnormal vibration and impact; 3. Do not let the battery contact with organic solvents; 4. Do not mixed-use the batteries of different type View>>
