How to Know When the Battery is Fully Charged?
1 Answers
If the battery is removed for charging, you can determine whether it is fully charged by observing the ammeter value on the charger or the indicator light on the charging device. The smaller the current displayed on the charger, the higher the battery's stored energy. When the current drops to tens of milliamperes, the battery is essentially fully charged. More details are as follows: 1. Some chargers display a red light during the charging process. When the battery is fully charged, the light turns green, indicating a full charge. 2. Some chargers will display "Fully Charged" on the screen once charging is complete. Generally, it takes about 5 hours to fully charge a battery.
