3 to 5 years. The lifespan of lithium batteries is not calculated in years but in cycles. Fuante disposable lithium batteries can be used for 3-5 years. Wuhan Fuante Technology Co., Ltd. is a domestic enterprise specializing in the production, research and development of raw materials. Lithium batteries. As a domestic high-tech enterprise, the company has a group of senior experts and professional technical personnel engaged in lithium primary battery research for 30 years.
The lifespan of a lithium battery is not calculated in years, but in cycles.
The lifespan of a lithium battery is “500 times”, which does not refer to the number of charges, but to one cycle of charging and discharging.
Nowadays, cell phones use lithium batteries. The cycle count of most lithium batteries is typically aroundn 500 times, that is, 0 to 100 corresponds to one cycle (a cycle of 100 corresponds to one cycle). reached 500 times, the mobile phone battery has already weakened, the internal resistance of the battery has increased, the activity of chemical elements inside has decreased, and it has entered a rapid consumption stage.
Everyone has had this experience. A very old cell phone turns off after making a call after being fully charged. It is understandable that the battery is exhausted.
Detailed information:
A charge cycle means that all the battery power is used from full to empty, then loaded from empty to empty. The process to reach full capacity is not the same as charging it once. For example, a lithium battery only uses half its power the first day, then it is fully charged. If it's still the same the next dayain, that is, if you charge it half and charge it twice in total, it can only be counted as one charging cycle and not two.
Therefore, multiple charges may typically be required to complete a cycle. Each time a charge cycle is completed, the battery capacity decreases a little. However, this power reduction is very small. High quality batteries retain 80% of their original capacity after multiple charge cycles. Many lithium-ion powered products are still used as usual after two or three years.
