The lithium battery has a cycle life of only 500 times?

For power batteries, the most concerned issues are usually battery life, battery safety and battery endurance performance. These all play a pivotal role in the process of consumers choosing batteries!

It is often said: Lithium battery can only be charged and discharged 500 times?

We often hear such a saying: Lithium batteries have a longer life than traditional batteries, with a cycle life of up to 500 times.Usually, we will take the life of lithium batteries as 500 times. We take it for granted that it is the number of recharges. In fact, it refers to 500. One charge and discharge cycle: One charge cycle refers to the process in which the power of a lithium battery is used from full to empty, and then from empty to full. This is not equivalent to charging once. For example, a lithium battery is only used that day Half of the battery, and then fully charge it. If the next day is the same, use half of the charge, and charge it twice in total. This can only be counted as one charging cycle, not two. Therefore, it may usually take several times Charge only to complete a cycle

Recharge the battery after it is exhausted to extend the life of the lithium battery?

Many people may wonder, is it necessary to replace the lithium battery with a new lithium battery after charging and discharging for more than 500 cycles? Many friends, in order to prolong the life of the battery, charge it every time when the battery is completely exhausted. This is true. Can extend the life of lithium batteries?

In fact, every time a charging cycle is completed, the battery capacity will be relatively reduced. However, the reduction in battery capacity is very small and does not affect the normal performance of the battery. It is understood that high-quality lithium batteries are now charged and discharged after multiple cycles. The battery capacity can still reach more than 80%.

How to extend the life of lithium battery?

1 Do not completely use up the battery power. Long-term overdischarge will reduce the battery life by 3 times. Excessive discharge will cause irreversible capacity loss. If the battery is not used for a long time, the battery should be removed from the instrument and stored in a dry and cool place. Charge it once within 60~90 days to avoid long storage time, and the battery will be too low due to self-discharge, causing irreversible capacity loss, because the best storage state of lithium batteries is half-charged storage

2 Don't overcharge, when the charging completion indicator is on, stop charging

3 Try to use the original lithium battery charger to charge. The original charger has strong supporting performance and moderate charging rate to avoid damage to the internal structure of the battery due to excessive current charging.
