i have always been intrigued about this, right from when i purchased my first laptop. since a laptop's battery has a particular limited number of charging-discharging cycles, (however big might be the number), what is the best way to use the laptop when i am AT HOME, so as to conserve the cycles of the battery?

 

possibilities:

 

a. remove the battery and plug-in the AC adapter directly and use the laptop (like i use a desktop).

 

b. use the laptop at home the same way when i am outside. ie., use the laptop when it is being charged; once it reaches 100% unplug the AC adapter and continue using the laptop.

 

c. without removing the battery, plug-in the AC adapter directly and use the laptop as long as i need, assuming that the laptop has some internal mechanism to automatically cut off the supply to the battery once it reaches 100% so as to prevent the battery from over-heating due to over-charging, therby protecting the battery's life.

 

my main concern is to conserve the number of cycles of the battery. i am so much concerned because the 9-cell-battery of my laptop (hp pavilion dv6t quad edition) lasted for a short time only. i am using the 2nd method. am i wrong in doing so? EXPERT KNOWLEDGE is most welcome. thanks in advance to everyone :)

Batteries function best and last longest if you charge and discharge fully.

sorry about the late response.

@Captain_Chicken: i completely agree with your statement, when i am using it on the move. wouldn't doing the same even when i using it at home, consume battery charge-discharge cycles unnecessarily? i don't know if i am right. please enlighten me.

 

@bc0306: even i think the same.

 

expert opinions with sufficient backing are most welcome, please. :)

I have a Lenovo unit that has been run mostly on the adapter but once a week I unplug the adapter and let the unit run until it shuts off, usually around 5%.  It recharges normally.  The battery run time has not diminished from 6 hours  when I bought it, three years ago.  The newer Li-ion cells are superior  with more power in a smaller package but this also creates more heat during charge and discharge cycles.

pardon my ignorance, but since i am not a native English speaker i could not understand what you meant by

 

"run mostly on the adapter but once a week I unplug the adapter and let the unit run until it shuts off, usually around 5%"

 

you mean the option C mentioned in my original question?

I've always used method C, just leave the battery in and connect to power for my work laptops and have never had issues with a battery, but then again I rarely use a laptop without power.  I have given my battery to a user who had a failed battery so that they could work until a replacement arrived.  Laptops will stop charging the battery before it gets to 100%, normally 95% to 97%.

 

I'd recommend against A as a power loss will result in loss of work.  Method B isn't much bette
