Attaining Battery longevity on a laptop.

Is it wise to keep a laptop always plugged in when not in use or when in use, in order to keep battery life/longevity or not?
I am believing to think this is not a smart idea me having done so.
Thank you

When using at home, if the battery is fully charged, remove it leaving the machine plugged in...

Leaving laptops connected to the mains power to keep the battery charged is not a good idea. Although most battery chargers will shut off when the battery gets fully charged, they do maintain some power to the battery & this generally heats the battery unnecessarily.
Batteries are generally designed to be cycled, which is discharging through use & then recharging when it get discharged to a certain point.

But then the MacBook Pro Notebooks of the last few years, especially those with the aluminum case, don't have user-easily-removable batteries, have to remove the screws holding the back panel on just to get to it. Haven't seen a late-model plastic case version.

Sadly, you did not tell us what notebook you are using, so any advice you get is just a guess! And it is second guessing highly qualified and educated electrical engineers using highly sophisticated computer-aided design computers to design YOUR notebook and select THAT battery for YOUR notebook.

There are relatively low-tech, cheap notebooks and batteries and there are highly sophisticated, high-tech notebooks and batteries! No way the same advice applies to all. Not all notebooks are created equal. Not all batteries are the same. Not all charging circuits are the same either. Especially compared to years ago. Today's charging circuits, even in entry-level notebooks are highly intelligent, fully capable of detecting when a battery needs charging, and when it is fully charged. And when fully charged, many chargers stop charging - so no need to remove the battery - or even unplug the charger with many notebooks.

Some notebooks require the battery in circuit for the notebook to work. Some notebooks don't care if you remove the battery. I NEVER remove the battery from my 4 year old Toshiba. Why? Because my manual doesn't say to!!!! I don't even have to unplug the charger when fully charged. What I do need to do with my specific notebook and battery is periodically allow the battery to fully discharge, then charge again. But this is NOT for extended battery life - but to ensure the battery status monitoring program is in proper sync with the actual battery status.

It is critical for EVERYONE to RTFM for YOUR specific notebook and see what YOUR manual says is best for YOUR notebook and YOUR battery. What may be best for mine, may not be for yours, or anyone else's.

So look in your manual! If it does not say to remove the battery, don't. It is the only expert source for proper advice concerning YOUR specific notebook and YOUR battery. Not me, or anyone else!

Itaregid you are so right. I feel like an idiot and, in theory at least, I'm supposed to me smart :-)
Anyhow, can't for the life of me find the manual and the online one one seems to be a generic one with no details regarding the battery.
However, I did find the specs for it and it says: ''37 Wh 2500 mAh 4-cell Li-ion battery pack''
Of course this detail refers to battery and not the 'battery charger' which may be of help as well.
Oh yeah the actual laptop is: Acer Aspire
E1-532P-2883
Thanks to all of you

Itaregid -thanks. When I had tried that same link you gave me B4 you gave it to me, something must have been going on with the Asus servers for it did not produce any positive results. So I am glad to have tried it again. The manual I had looked at did not have as much info as the one I was able to get now seems to have.
All info needed has been provided.
Once again thanks to all.

Considering you have an Acer and not Asus, no surprise!

Thanks :-) The day has been grim and grey so you making me laugh was a good thing. I had been trying to solve an ASUS problem for the last few days hence, my brain having written 'asus' instead of 'acer' but rest assured it was Acer I meant since I was on the phone with them shortly after, when I was doing all of this, and it is they who sent me the generic manual. But nevertheless, well done buddy for the observation.
Some people (who aren't Asian) say all Asians look alike, since both of the companies are from Taiwan, do you suppose something similar happened--they all look alike? Just joking. As to those of you who may be reading this who happen to be Asian--I lived there for over 10 years, so no, you do not all look alike to me.
