No more than 2 years. Mercury released into nature in batteries will slowly overflow from the batteries, enter the soil or water sources, and then enter the human body through crops, damaging human kidneys. A battery refers to a cup, tank or other container or part of a composite container containing an electrolyte solution and metal electrodes to generate electric current. It is a device capable of converting chemical energy into electrical energy. It has positive and negative poles.
Ordinary lithium batteries generally cannot be made into power batteries. For power batteries, the consistency, discharge rate, maximum output continuous current and maximum instantaneous output current of the lithium battery should be considered if series and parallel. There are not many power battery connectionss, the maximum continuous output current and the maximum instantaneous output current are not important. It can also be made from ordinary lithium batteries, but it is better not to do this. causing the battery core to swell or even explode.
