How do I know if my battery is fully charged?

One way is simply to look at the charging indicator light on your device. Your battery is probably fully charged if the light is green or blue. Another way to tell is by looking at the voltage reading on your charger. Most chargers will have a display that shows the battery’s current voltage as it charges.

Why does a 'fully charged' cell not stay at 4.2 V?

Don't sweat it. There are three main reasons why a 'fully charged' cell does not stay at 4.2 V after charging. Firstly the cell has internal resistance, so any current going into it will raise the terminal voltage, while any current drawn from it will lower the voltage. Secondly, most chargers do not put in a full charge.

What happens if a battery is not fully charged?

Then the current (green line) must be reduced to prevent the voltage rising any further (the 'constant voltage' phase). When current drops to ~10% of the 'constant current' rate, the charger shuts off (yellow line). At this point the battery is not quite fully charged (had the charger not cut off it could have pushed a few more mA into the cell).

How do you know if a lithium-ion battery is fully charged?

Signs that a lithium-ion battery is fully charged can vary depending on the device and manufacturer. However, there are some common indicators to look for. One of the most obvious signs is when the charging icon or LED indicator on your device changes from red or orange to green.

Why is my lithium ion battery not fully charged?

Unfortunately, when your Lithium-ion battery can not be fully charged, there could be a variety of reasons behind the problem.
