Turn Off Battery Charging to Extend Laptop Battery Lifespan : Dell Quickset

For your information, this is not how to save battery so that you can run your laptop or notebook for longer periods, but by doing this you can extend your battery lifespan, keeping the battery healthy for few years. A normal characteristic of a rechargeable battery is that its operating duration decrease over time. Keeping best battery charging practice would increase its life a little more.

Two things we want consider that greatly affect a rechargeable battery:

  1. Heat from the running computer can shorten battery lifespan
  2. Frequent Draining and re-charging makes battery health further weak.

Laptop’s that are used by most people today hold Li-ion batteries. Its life also depend upon how long the battery spends plugged in. these batteries has a finite number of charge cycles say, 300 times or more. Charge cycle of a battery is counted neither  if the battery is drained completely in one session nor one charge cycle for every instance the device is unplugged and plugged in again. Charge cycles for Li-ion batteries counts based on a 100 percent discharge even when it’s summed over multiple sessions. this means that if you discharge you laptop battery to 50%  and charge it back to 100% then discharge again to 50%, then it is counted as one charging cycle. So small discharging period never kills a Li-ion battery.

But in the other hand, keeping the Li-ion battery fully charged is not good. There’s a fair chance of overcharging the battery if it stayed plugged in. Another problem arise when you’re in a place where very frequent power outages occur since very shallow discharges also affect the battery in a negative way.
