Batteries are a chemical substance and therefore have a certain service life. Primary batteries such as alkaline dry battery (including ordinary alkaline batteries) cannot be charged, and of course there is only one service life. For rechargeable batteries, we generally use the number of recharges to measure the length of their service life. The cycle life of nickel-cadmium batteries is about 300~700 times, the number of rechargeable times of nickel-hydrogen batteries is generally 400~1000 times, and that of lithium-ion batteries is 500~800 times. The service life of rechargeable batteries is not only affected by factors such as the raw materials and manufacturing processes used in the production of the battery, but also has a close relationship with the charging and discharging method of the battery and the actual usage. For example, someone started to use 6 nickel-cadmium batteries in 1985, and they have continued to use them, but the battery capacity has been somewhat reduced. It seems that as long as the method of use is reasonable, the rechargeable battery can reach or even greatly exceed the nominal service life.
