How to use lead-acid batteries

1. Do not short-circuit the battery. When the positive and negative electrodes of the battery are in electrical contact through external materials, the battery is short-circuited. For example, an unpackaged battery placed in a pocket will be short-circuited due to contact with metal materials such as keys or coins. 2. Install the battery correctly so that the polarity marks ('+' and '-') of the battery correspond to the marks of the electrical appliance correctly. If the battery is incorrectly installed in the reverse direction of the electrical appliance, a short circuit or charging may occur, resulting in a rapid increase in the temperature of the battery. 3. Don't try to charge the battery. Charging an unrechargeable primary battery will generate gas and heat inside the battery. 4. Do not forcibly discharge the battery. When the battery is forced to discharge, its voltage will be lower than the design performance and generate gas inside the battery. 5. Do not heat or solder the battery directly. When the battery is heated or soldered, the heat will cause a short circuit inside the battery. 6. Do not disassemble the battery. When the battery is disassembled or separated, there may be contact between the battery components, resulting in a short circuit. 7. Do not mix old and new batteries or batteries of different models and brands. When the batteries need to be replaced, all batteries should be replaced with new batteries of the same brand, model, and batch at the same time. When batteries of different brands and models or different old and new batteries are used together, some batteries may over-discharge due to the difference in voltage or capacity between different batteries. 12V4AH lead-acid battery 8. Do not deform the battery. Do not squeeze, puncture or damage the battery in other forms. These abuses will often cause a short circuit in the battery. 9. Do not put the battery in the fire. When the battery is put into a fire, the gathering of heat may cause explosion and personal injury. Except for suitable and controllable incineration treatment methods, do not try to burn the battery. 10. Do not let children touch the battery or replace the battery without adult supervision. Those batteries that are likely to be swallowed should be kept out of the reach of children, especially those that can fit into the food gauge shown in the figure. Once someone has ingested the battery, they should seek medical help immediately. 11. Do not seal or change the battery. Sealing the battery or changing the battery in other forms will block the safety valve of the battery, so that when gas is generated inside the battery, it cannot be discharged in time. If it is deemed necessary to change the battery, the manufacturer’s recommendations should be obtained as much as possible. 12. For batteries that are not in use, they should be stored in their original packaging and kept away from metal materials as much as possible. If the packaging has been opened, they should be discharged in an orderly manner and not stacked in disorder. When unpackaged batteries and metal materials are mixed together, it may short-circuit the battery. The best way to avoid this situation is to use their original packaging to store unused batteries. 13. Unless it is used in emergency situations, batteries that have not been used for a long time should be removed from the electrical device as much as possible. When a battery does not achieve satisfactory results or can be expected to be unused for a long time, it is beneficial to remove it from the device, although the batteries currently on the market are equipped with protective casings or other methods to control leakage. But a partially or completely used battery will still leak more easily than an unused battery.
