How to use lead-acid batteries?

(1) Do not short circuit the battery. Batteries can short-circuit when their positive and negative terminals come into electrical contact with external materials. For example, an unwrapped battery in a pocket can short-circuit by coming into contact with a metal material such as a key or coin.

(2) Install the battery properly so that the battery polarity marks (" + "and" - ") correspond correctly to the markings of the appliance. If the battery is installed back into the appliance incorrectly, a short circuit or charge may occur, causing the temperature of the battery to rise rapidly.

(3) Don't try to charge the battery. Charging a non-rechargeable battery creates gas and heat inside the battery.

(4) Do not force the battery to discharge. When a battery is forced to discharge, its voltage will be lower than the designed performance and create gas inside the battery.

(5) Do not directly heat or weld the battery.  When the battery is heated or welded, the heat can cause a short circuit inside the battery.

(6) Do not remove the battery. When the battery is removed or separated, there is a possibility of contact between the battery components, resulting in a short circuit.

(7) The mixing of old and new batteries or batteries of different models and brands is prohibited. When replacing batteries, replace all batteries with new ones of the same brand, model, and batch. When different brands and models of batteries are used with different old and new batteries, some may overdischarge due to differences in voltage or capacity between the different batteries.

(8) Do not deform the battery. Do not crush, puncture, or otherwise damage the battery. These abuses often lead to a short circuit in the battery.

(9) Do not put the battery in the fire. When a battery is placed in a fire, the accumulated heat can cause an explosion and personal injury. Do not attempt to burn batteries unless appropriate controlled incineration methods are used.

(10) Do not allow children to touch or change batteries without adult supervision. Batteries that are easily swallowed should be kept out of the reach of children, especially those that can be placed in a food gauge like the one shown in the picture. If someone takes the battery, seek medical help immediately.

(11) Do not seal or replace the battery. Sealing the battery or replacing the battery in other ways will block the safety valve of the battery and prevent timely discharge when gas is generated inside the battery. If you think you have to replace the battery, you should try to get the manufacturer's advice.

(12) For unused batteries, keep them in their original packaging, away from metal materials. If the package is opened, it should be discharged in an orderly manner. When unpacked batteries are mixed with metal materials, it is possible to short-circuit the batteries. The best way to avoid this is to use original packaging to hold unused batteries.

(13) Batteries that have not been used for a long time should be removed from electrical equipment as much as possible, unless used in an emergency. It is beneficial to remove the battery from the device when its performance is unsatisfactory or when it is likely to be expected to be out of use for an extended period of time, although batteries currently on the market have a protective housing or other means of controlling leaks. But partially or completely used batteries are still more likely to leak than unused ones.
