Battery service life

The battery is a chemical substance and therefore has a certain service life. For example, a battery such as a dry battery (including an ordinary alkaline battery) cannot be charged, and the service life is of course only once. For rechargeable batteries, we generally measure the length of service life by the number of times of charging. The cycle life of nickel-cadmium batteries is about 300~700 times, the number of rechargeable nickel-hydrogen batteries is generally 400~1000 times, and the number of lithium-ion batteries is 500~800 times. The service life of rechargeable batteries is not only affected by factors such as raw materials used in the production of batteries, manufacturing processes, etc., but also closely related to the battery charging and discharging methods and actual use. For example, the six HITACHI nickel-cadmium batteries that someone started using in 1985 have continued to use until now, but the battery capacity has somewhat decreased. It seems that as long as the method of use is reasonable, the rechargeable battery can fully meet or even exceed the nominal service life.
