All rechargeable batteries are consumables. With the increase of the chemical life of the battery, the amount of electricity that the battery can store will decrease, which will shorten the time that the equipment can be used before it needs to be charged. The performance of the battery will also be degraded.
According to the official description, the cycle life of the battery is about 500 times. This refers to the life statement that can maintain the peak performance of the battery. According to the daily charging rhythm, the battery will become very durable after about one and a half years.
Lithium batteries have no memory, so we can charge them while using them, and it is best to keep them within the range of 45%-75%. We shouldn't charge the battery when it is too low, 20% of the time, or all night. These conditions will cause some damage to the battery, although there is overcharge protection.
