If you have a replacable battery why do you care? Use your shit and replace when/if needed, stop the autism

Keep it in but let it run down to about 30% every now and then. Remove for long term storage, making sure it is 50% to 70% charged.

I have an 18 year old Toshiba 460CDT that spent 8 years in storage, that still holds two hours of charge thanks to this method.

Your old laptop has NiMH batteries, not lithium based batteries. You treat them differently. Lithium batteries have a 30 month half-life, regardless of charge cycles, from the moment the components are mixed. Charge cycles further reduce their capacity.

>in order for your battery to last you a long time, should you take it out of the notebook when you're at home or should you just keep the battery in the notebook forever?

Don't leave the battery plugged in when it's 100% full, especially if the laptop is going to get hot. Functional capacity is reduced as lithium batteries get hotter which can cause them to be effectively overcharged and cause damage.

No matter what you're going to have a shit lithium battery in 3 years and you should expect to replace it or relegate the machine to desktop work only.

The thing I understand about keeping a laptop in storage for a long time is to keep that shit around 50%, or what >>54958585 said.

But what about Lithion-Ion battery laptops that you use 24/7? Should you let it cycle between 10% - 90% (since fully charging and then discharging makes battery kill), or is it okay to always keep it plugged in and topped-off?

And when the laptop is not in use, let's say for a few hours, do you still want to keep it plugged in?

Thanks anons.

in use
>plugged in or battery but never let the battery go down to 0%

storage
>charge it between 50~70% and turn it off

suspend
>leave it unplugged (additionally I turn wireless/wifi off, seems that even in suspend it helps draining the battery faster when not plugged in, macbooks do that for example)

charging
>leave it plugged in and just disconnect it when it seems fully charged (I never leave it plugged in all night, if I need it for the day I make sure charging it the night before)

what if you're a poorfag who skipped dinner for a year to get a laptop?

my 1997 Toshiba Libretto (19 years old) has Li-Ion batteries so stop making assumptions without knowing for sure.

Thanks anon!

Another quick question: Does having your battery get stupidly close to being completely discharged -- say 1% away -- have an impact on the lifespan? And how does it compare to say, 3%, or 8%? Or does the threshold not matter as long as it's not *completely* discharged?

Curious, because I shat myself earlier today when I managed to get my battery down to 1% earlier today. (Battery indicator in the taskbar stopped updating properly, and I only noticed it by complete chance in a desktop application that showed the remaining battery life.)

Then you're full of shit. You have a new battery or different chemistry. You do not have a lithium battery that old that holds any appreciable charge.
