Charging laptop battery more efficiently for a longer life

What will happen to my laptop battery when it is not fully discharged before recharging it? Does this affect the efficiency of the battery in any way? Do I have to charge the battery to 100% before using it or it is alright to stop charging before it reaches the 100% mark? Is there a downside to keeping the charger on while my battery is fully charged? Does this affect the battery’s efficiency?

Hello,

Laptop is such a machine that enables enjoying the PC anywhere. When it’s not on direct connection, it uses the battery inside it to get the electricity supply to run the hardware. When it connects to direct connection, it recharges the battery and runs on the direct connection.

It’s recommended and safer to use battery after it is 100% charged. The chemicals inside the battery are totally prepared again to provide a long journey support. If you disconnect the charger before it’s 100% charged, it’s OK but will give a pressure on the battery that will slowly bring the battery down.

The best practice of using laptop is to use it on direct electricity supply. The more you run your laptop on battery, the life of the battery slowly keeps on going down. If you travel a lot, make sure that your laptop is charged full before going out and after returning home, give it a full charge.

Thus, you can ensure a long life for your laptop’s battery.

Hello, How are you? Older Ni-Cad batteries suffered from ‘memory effect’. The capacity of this type of battery decreases if it is not fully discharged. So charge the battery after fully discharging. But Lithium-ion battery has not this type of effect. So for this type of batteries fully discharging option is not mandatory. Because Lithium-PO batteries use a controller, which regulates internally. This has eliminated “memory effect” of the battery. That is exactly it. Learn more.

Like what Apple recommends to users with laptops running on OS X, they can leave their machines connected to the charger even for a month without disconnecting. But at least once a month, you have to disconnect the laptop from the charger maybe for 24 hours just to allow it to run on battery.

The total lifespan of a laptop’s battery or any other battery depends on how you use your device. The more often you charge, the faster its lifespan will decrease. All rechargeable batteries have limited lifespan and its average lifespan is determined by the cycle count which is then equivalent to charge and discharge.

In a laptop computer, the average lifespan of a Li-Ion battery is about 700 to 800 cycles and normally lasts around 2 to 3 years. According to Apple, you can allow your laptop to be connected to the charger even when the battery is full. This will not damage the battery. In this state, the laptop will run on AC power instead of battery.

But you need to let your laptop run on battery at least once a month to allow the battery to discharge normally. The idea here is simple. When the battery is charging and it reaches the full charge capacity, there is a mechanism in the laptop’s power supply that will stop the charging and shifts to AC power.

When the laptop is running on AC, the battery will remain at its level without discharging therefore preventing the cycle count from decreasing and prolonging its life.
