How to use lead-acid batteries
(1) Do not short the battery. When the positive and negative electrodes of the battery are electrically contacted by an external substance, the battery is short-circuited, for example, an unpackaged battery placed in a pocket may be short-circuited by contact with a metal material such as a key or a coin.
(2) Install the battery correctly so that the polarity mark ("+" and "-") of the battery correctly corresponds to the mark of the electric appliance. If the battery is incorrectly mounted back into the appliance, a short circuit or charge may occur, causing a rapid rise in battery temperature.
(3) Do not attempt to charge the battery. Charging a non-rechargeable primary battery produces gas and heat inside the battery.
(4) Do not force the battery to discharge. 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, heat can cause a short circuit inside the battery.
(6) Do not disassemble the battery. When the battery is disassembled or separated, there is a possibility of 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 you need to replace the battery, you should replace all the batteries with new batteries of the same brand, same model, and same batch. When batteries of different brands and models are used together with different old and new batteries, some batteries may be over-discharged due to the difference in voltage or capacity between different batteries.
(8) Do not deform the battery. Do not crush, puncture, or otherwise damage the battery. These abuses can often cause a short circuit in the battery.
(9) Do not put the battery in a fire. When the battery is placed in a fire, the gathering of heat causes an explosion and personal injury. Do not attempt to burn the battery except for a suitable controlled incineration method.
(10) Do not allow children to touch the battery or replace the battery without adult supervision. Batteries that are likely to be swallowed should be kept out of reach of children, especially those that can be placed in the food gauge shown in the figure. Once someone has taken the battery, seek medical help immediately.
(11) Do not seal or change the battery. Sealing the battery or other forms of changing the battery will cause the safety valve of the battery to be blocked, so that it cannot be discharged in time when gas is generated inside the battery. If you think you have to change the battery, you should try to get the manufacturer's advice.
(12) For unused batteries, they should be stored in their original packaging and kept away from metal materials. If the package is opened, it should be discharged in an orderly manner. When unpackaged batteries and metal materials are mixed together, it is possible to short-circuit the battery. The best way to avoid this is to use their original packaging to hold unused batteries.
(13) Unless it is used in an emergency, 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 perform satisfactorily or can be expected to be unused for a long period of time, it is beneficial to remove it from the device, although the batteries currently on the market have a protective casing or other means to control leakage. But a partially or completely used battery will still leak more easily than an unused battery.
