How to increase battery life of a new replacement battery?

[terryvalencia]

I'm buying a new replacement battery for dell laptop and I want to make it live till it is built to live. Except stuffs like turning brightness down etc what else can I do? Specially while charging? Should I use it plugged on 24*7? Or should I let it discharge(Use without plugged on)? How should I use the battery for it to last as long as possible?
The battery is LION, 42Wh, 3 cell battery.

That can be 1 day from now or maybe a couple of years from now, there's no guarantee of it's lifespan. Buying a genuine battery ensures that you're backed by a part that's meant for your laptop. Buying something cheap from a store on Ebay or Aliepress can and will result in the battery either swelling or sending too much power while malfunctioning.

You charge the battery to 1000% and then discharge to 10% before you reconnect the wall adapter to the laptop to recharge the battery.

You can undervolt your CPU and it's iGPU to reduce the amount of power draw and that helps make sure your battery has more power to deliver to the laptop when your wall adapter is disconnected.

You could also try and remove unnecessary background app's to help reduce the amount of CPU/resource usage an essentially power usage. This goes hand in hand with allowing the battery to provide power to your laptop for longer when taxed with productive apps.

A few things:

• Keep the battery in a human comfortable temperature as much as possible
• Don't keep it charged to 100% all the time if you can help it.
• Avoid discharging to 0% as much as possible

If anything, just avoid subjecting the battery to high-ish temperatures.

My Dell G5 has a battery care app (can also be controlled in the BIOS) that allows you to stop it charging at a set %. This is for when the laptop is used mainly plugged into the mains. I have mine set to stop charging at 80%.

Do not buy a "compatible" replacement battery.
Buy only a genuine dell replacement with the same part number as the original.

Batteries may have chips to control charging and not all compatible units will work properly.

Yes, you may have to pay more.
