I bought a new cell.
I never let the power go below 80%.
Now the cell(power) has become weak.
It can't even withstand for 5mins with full power.
What was the mistake i made ?
Did i overcharge my cell ?
I don't understand the chemistry behind that!
Can anybody explain ?

don't do that again. always let the battery empty itself before recharging

1. What is cell overcharging?

Cell overcharging is when a battery or cell is charged beyond its recommended capacity, causing damage and potential hazards.

2. What are the potential consequences of cell overcharging?

Cell overcharging can result in reduced battery life, overheating, and in extreme cases, explosion or fire.

3. How can I tell if I have overcharged my cell?

There are several signs of overcharging, including excessive heat, bulging or swelling of the battery, and reduced battery performance.

4. What are some common mistakes that lead to cell overcharging?

Some common mistakes include leaving the battery on the charger for too long, using the wrong charger or charging at too high of a voltage, and charging the battery too frequently.

5. How can I prevent cell overcharging?

To prevent cell overcharging, it is important to follow the manufacturer's recommendations for charging, use a charger specifically designed for the battery, and avoid leaving the battery on the charger for extended periods of time.
