\nLead acid batteries: In general application scenarios, their theoretical charge and discharge cycle life is approximately 300 times. If used improperly, the lifespan may be shortened. Special types of lead-acid batteries, such as gel batteries and maintenance free batteries, can theoretically achieve a charge and discharge life of 1000 times, but in practical applications, it is usually about 500 times.
\nNickel hydrogen battery: Under normal usage conditions, the charging and discharging life of nickel hydrogen batteries is about 500 times, which is equivalent to charging and discharging once a day and can be used for about a year and a half. If users stop charging when the battery is at 30% capacity, the lifespan of nickel hydrogen batteries can be extended to approximately three years.
\nLithium ion batteries (including polymer lithium batteries and 18650 lithium batteries) have a theoretical charge and discharge life of approximately 500 cycles. High rate lithium batteries are sensitive to high current discharge and typically have a lifespan of less than 300 charge discharge cycles. However, due to its excellent durability, lithium iron phosphate batteries have a theoretical lifespan of up to 2000 charge and discharge cycles, which means they can maintain a usage time of 6 to 8 years under normal conditions.
\nLithium polymer batteries: Under normal use and maintenance conditions, the average lifespan is approximately 2 to 4 years, but high-quality batteries and optimized usage conditions can extend the lifespan to 5 years or even longer.
\nFactors affecting battery life
\nCharging habits: Frequent shallow charging and discharging can extend the battery’s lifespan, while deep discharging and overcharging can shorten the battery’s lifespan.
\nEnvironment of use: High temperature environments can accelerate the aging process of batteries, so prolonged use of batteries in high temperature environments should be avoided.
\nStorage conditions: Batteries that are not used for a long time should be stored in a dry and cool place, avoiding storage after complete discharge to extend the battery’s shelf life.
