What is the best choice for laptop battery ?
I Usually work with my laptop at home so I usually have external power source , and I dont need to use battery , what should I do to increase battery life? take it off once it is fully charged ? take it off around 10% charged ? or dont take it off?
When using a laptop as a desktop replacement the battery should not be left in for long periods of time. The laptop will over time discharge the battery. Remove the battery – making sure that it is charged to 40% and store it in a dry, warm place. Ensure that it is wrapped protectively and nothing will be dropped on it.
The battery should be re-installed every 3-4 weeks and allowed to fully discharge. Leaving a battery in storage for longer than this without using could cause the battery to fully discharge as the circuitry of the battery itself consumes power.
Leaving a battery in a laptop while using an electrical outlet for long periods of time will keep the battery in a constant state of charging up and that will reduce the life cycle of the battery.
The other is to keep the battery in and fully discharge it once a month. Then recharge it. If your battery is in your laptop, think of it being like a backup power device. If your power goes off or glitches you could lose what you were working on if your battery is out. You should get 2 to 3 years out of a battery and maybe 300 recharges before it starts going bad. To me the security of not losing files I am working on is worth it keeping the battery in. My wife's laptop has a 4-5 year old battery in it, she keeps it in all the time and still gets about 85% battery strength.
