Customer ServiceA Li-ion battery with a voltage of 3.5 V may be 3.6 V when full and 3.3 V when almost empty (i.e., 92-98% of its total capacity has been used). Note that a Li-ion battery can be discharged to 3V and lower, but the battery shows 0% or ''fully discharged'' at 3.3V to ensure maximum useful capacity of the battery.
Customer ServiceIn this Science 101: How Does a Battery Work? video, scientist Lei Cheng explains how the electrochemistry inside of batteries powers our daily lives. Whether a traditional disposable battery (e.g., AA) or a rechargeable lithium-ion battery (used in cell phones, laptops and cars), a battery stores chemical energy and releases electrical energy
Customer ServiceWhat to Do if Your Rechargeable Battery Dies. It is obvious that if a rechargeable battery dies, it needs to be replaced, as a battery that no longer holds a charge is of no use and needs to be recycled or properly disposed of.

Look for a Protection Circuit: A protection circuit helps to prevent overcharging or other damage to the battery by monitoring its temperature and voltage. If the device is equipped with this feature, it should be clearly marked on the charger.
To create a battery charge indicator, you will need the following components: The microcontroller serves as the brain of the battery charge indicator. It reads the battery voltage, processes the data, and controls the display. Arduino is a popular choice due to its ease of use and wide range of compatible libraries.
Make sure that your battery is compatible with the voltage of your device by checking this information before connecting it to the charger. Read the Amperage Rating: The amperage rating, or “A” on the charger, tells you how much current should be flowing through your battery as it charges.
A: Yes, battery charge indicators are commonly used with rechargeable batteries, such as lithium-ion batteries. However, it’s essential to ensure that the voltage thresholds in the code are adjusted to match the characteristics of the rechargeable battery.
Some chargers will have a green light that indicates when the battery is fully charged, while others may have an LED display to show charge levels. Once your battery is fully charged, disconnect it from the charger and store it in a cool, dry place. Do not leave your battery connected to the charger for too long, as this can cause damage.
