If you want laptop battery longevity,there must be a good start.A new laptop battery at the first boot with 3% of the general power,then you should not use external power but exhausted all the power in the remainder until the shutdown.After the exhaustion of the battery,you could charge again.Charging time must be within 14 hours, repeated three times, in order to fully activate the battery, in order to lay a good foundation for future usage.

The measure of a Notebook computer’s battery life is how many times of charging.Do not make your battery work if not neccessary.If you would not use the laptop battery for long time,When your battery is 50% power,you should save it in a cool place.If you have make it work,you’d bettery exhaust it then charge it.Do not plug in the AC power when your battery is not exhausted.When your battery is 100% power,you should cut down the input of AC power.Because over charging would make the laptop battery hot so that reduce the life of a battery.

Generally,the notebook contains the battery protectiong function,which means battery would not be damaged for the common operation.But there will be likely to be damage for lifespan limited or other reasons.

If you want to take a try to check whether these theory are correct.How about take a Thinkpad X6 battery or Acer TravelMate Battery
