The main batteries on the market are rechargeable batteries NiMH batteries and lithium-ion batteries, but sometimes you will find that the charge is not charged because of the internal reasons of the battery itself and the external reasons when the battery is charged. Here we mainly talk about lithium-ion batteries.
The battery does not charge the internal cause is mainly the battery factory is substandard products so that the battery zero voltage or because of long-term shelving so that the battery is discharged to zero voltage. In addition, the battery pack connection error may also occur in the case of battery charging, but the likelihood of this situation is relatively small, because the factory generally requires all batteries to be inspected. Finally, it is because the battery is used for a long time after the aging of electronic components and off the impact of circuit protection function, which will lead to charging into the power.
The charger does not match the battery, which causes too much instantaneous current when charging, which is the main external cause of the battery not charging. Second, the failure to charge will also result from the charging device’s inability to output voltage. Finally, the environment around the charger and rechargeable batteries has an impact on charging; if the temperature is too high or low, the battery cannot be charged.
Finding the cause of the battery’s failure to charge and selecting a workable solution are the remedies for the issue. Determine whether the battery is not charging for internal or external reasons, then identify the exterior causes before identifying the internal causes. If the charging procedure causes a problem, you can try a different charging procedure. If the issue is internal, however, professional battery knowledge and battery testing equipment are needed to resolve it.
