can your laptop battery be overcharged?

Most laptops today use lithium ion (Li-ion)batteries.
Li-
The ion battery is not a problem and does not affect the battery life.
These batteries can be charged 300 to 500 times, and they have an internal circuit that can be fully charged to stop the charging process.
The control system can prevent overcharging, which can cause the lithium ion battery to overheat and possibly burn down.
That\'s why Li-
More expensive ion batteries.
The only way for Li
If the charging system fails, the ion battery will overcharge and then the battery will heat up in the charger.
If you are not planning to use your laptop for a long time, you can extend the battery life by storing the lithium ion laptop battery with 50% of the power.
A fully discharged battery remaining for a long time will lose its charging capacity.
When the battery is idle, the fully charged battery discharges and loses its effectiveness.
This is why it is recommended to discharge Li-
The ion battery was almost dead before it was turned off. Running a Li-
The complete shutdown of the ion battery will reduce the capacity.
Keep the battery in a cool place and don\'t store it for a long time when the computer is fully charged.
Used laptop with nickelcadmium (Ni-Cd)
And nickel metal hydrogen (Ni-MH)batteries.
They require more maintenance than lithium-ion batteries.
They must be fully discharged and then fully charged so that they do not lose battery life.
Only when these batteries go through excessive charging and discharge cycles can they be overcharged, which reduces their effectiveness and capacity.
It is best to fully charge all batteries before use;
Then use the battery power supply before charging until it reaches the best level for each battery type.
