Question about the battery

Hello


I just bought a new laptop.
I would like to know what is the best for the battery.
Should I use the laptop with the adapter always pluged inm or at least as much as possible?
Or is it better to use it only with the battery and when it's level becomes critical to plug in the adapter?

Only use the adapter when you need to charge the battery. This will prolong the life of the battery.
Use the adapter when you need it. But most important, use the battery. An unused battery will lose capacity, quick. To keep the battery in top shape, at least once a month drain it to 30% then charge it to full capacity. Note that draining that much isn't needed if you use the battery on a daily basis, only if the laptop if the power adapter is used most of the time.

Also check out the FAQ from laptop manufacturers, as they usually know best:

Hope this helps.
Best battery life:

Drain to 40%.
Remove.
Run laptop with battery removed.

Every 2-4 weeks, install battery.
Charge and run.
Deplete to 40%.

Repeat.

Keep these in mind:
Each drain/charge cycle reduces battery capacity.
Batteries store longest at 40% charge.
Batteries lose capacity and longevity when running at high temperatures.  Laptop temps are 120-130F.

So, using the method above, you:

Decrease charge cycles to 20-30 per year, 300/yr.
Avoid storing batteries at full charge.
Store batteries at room temperature, not 120+F prolonged exposure.

Just remember to carry your charger on trips, and top it off before you leave.
