With the change in battery storage materials, lithium batteries have replaced older types of batteries. However, lithium batteries have a self-discharge characteristic. If a device uses a lithium battery as a power source, it will discharge itself if it is not used for a long time. Many people don't know how to restore it. This article will discuss how to restore a lithium battery that won't charge.
1. Replace the charger
Taking mobile phones as an example, mobile phones use single lithium batteries. When these lithium batteries fail to charge, it's not necessarily a problem with the battery itself; it's very likely a problem with the charger, charging port, or charging plug. It's important to know that lithium batteries are intelligent batteries and must be charged using the original charging equipment.
When the charging port, data cable, or charging plug is damaged, the battery cannot be charged normally. The damaged device or component must be replaced before it can be charged normally.
II. Replacing the lithium battery
Although lithium batteries are a replacement for older batteries, they, like older batteries, have a limited lifespan. When fully discharged, their lifespan is around 500 cycles. During daily use, the charging and discharging cycles of lithium batteries will also accelerate the wear and tear on their lifespan.
If the lithium battery we are using has reached the end of its lifespan, then it will no longer be able to charge properly. The only solution is to replace it with a new lithium battery; there is no other way.
III. Low-voltage charging method
If we are using a high-capacity lithium battery for vehicles, when the lithium battery is left unused for a long time, it will be in a low-voltage state due to its self-discharge characteristics. At this time, it will definitely not be able to be charged.
A low-voltage charger can be used to charge the lithium battery. Once the battery has gained some charge, it can be fully charged using the original charger. However, this method only works for some lithium batteries; it may not be effective for certain types.
