Why does Deep Discharge Shorten the Life of Lithium Batteries?

As an Emergency Lighting Battery Supplier, share with you. Lead-acid batteries have a memory effect. Part of the power is often used and then fully charged. The battery memory effect will cause part of the battery to be unable to discharge and reduce the power. Some car riders who have forgotten to turn off the lights, etc., use all the battery power and then fully charge it, and they will find that the battery life is reduced, but this behavior is precisely to discharge and charge the lead-acid battery deeply. It should be normal. Maintenance means. According to the current situation provided by car friends, it seems that car batteries are somewhat similar to lithium batteries, and the battery life is drastically reduced after deep discharge.

A regular deep discharge of a lithium battery is beneficial to "activating" the lithium battery and can slightly increase the capacity of the lithium battery. Perform a full discharge of the lithium battery on a regular basis. The full discharge is the first under-voltage protection after cycling under normal load on a flat road. After the first undervoltage protection of the lithium battery, the voltage of the lithium battery will rise after a period of time and return to the non-undervoltage state. At this time, if the battery is used again, the lithium battery will be seriously damaged. Fully charging the lithium battery after the complete discharge will feel that the capacity of the lithium battery has increased.

The effect of the depth of discharge on the lithium battery is: the deeper the depth of discharge, the easier the life of the lithium battery is to shorten; the other aspect is the performance on the discharge curve, the deeper the discharge, the more unstable the voltage and current. The depth of discharge is closely related to voltage and current, and it can be said to be expressed in voltage and acting on current. Under the same discharge system, the smaller the voltage value, the deeper the discharge depth.

If the battery is not fully charged frequently, the battery will produce a kind of "memory", which will affect its continuous mileage and also consume the battery life. Lithium batteries are rarely fully charged when they are just bought. Long storage time will reduce the capacity of lithium batteries. In addition, you need to pay attention to choosing a better quality protection board. Pay attention to these points, your lithium battery will be no problem for five or six years.

How to extend the life of lithium batteries?

①Charge in time: Because the lithium battery will enter the vulcanization process after being discharged, if it is charged in time, the less serious vulcanization can be removed. Therefore, the lithium battery should be charged as soon as possible after use, and the battery should be fully charged as much as possible.

②Cooling and charging: Do not charge immediately after each long-term use. You should wait for the lithium battery to cool for 10 to 30 minutes before charging, which can extend the life of the lithium battery.

③Regular inspection: When the capacity of the lithium battery decreases, you should go to the local outlets with lithium battery repair and repair technology to check to determine whether the lithium battery is declining normally, and maintain the lithium battery regularly to improve the working condition of the battery.
