The life of carbon electrodes is short, easy to wear, and unsafe. According to the usage conditions, the service life will not exceed 8 years, and the limit service life is 4-5 years. If the contact is not good, oil leakage will easily occur, which will intensify wear and tear. It will cause the electrode to sink, and if it is serious, the service life will be reduced. So this is also the reason why battery life is becoming more and more important in the current lithium battery market.
Just looking at the logo is useless, you have to take it apart and take a look.
The battery will be useless after 1-2 years of use.
Lithium batteries will decay very slowly. The life expectancy depends on the size of the battery capacity. Generally, the battery life is 1-2 years, and generally, the life span is longer.
It is related to the battery capacity, the higher the capacity, the longer the service life, and the smaller the capacity, the shorter the battery life
If the battery cell is new enough, the voltage is high enough, and the number of charge and discharge cycles is enough, there is no service life. From 100 to 90 times, don't discharge them all at once. Generally, 2 or 3 times of discharge are enough. If you discharge them all, it will last for 3 to 4 years. If it is a rechargeable Ni-MH battery, generally speaking, the service life will be shortened if the rechargeable capacity is below, and the battery will lose less than 90% of its capacity in 2 or 3 years.
Generally speaking, the service life of the battery is related to the capacity of its rechargeable battery.
It's not a problem to use it for a year or two, but you have to make sure that you don't want to recharge it after it's completely broken.
The impact of lithium battery cycle times on battery life is not as great as imagined. This involves the use and specification matching between batteries. There is no saying that the more cycles, the greater the damage to the battery, but the damage caused by over-discharge and over-charge can be said to be very large. Therefore, the setting of the number of cycles is particular.
