Laptop and Battery Life

  lulubelle 17:44 26 Dec 2007

Hi All,
I have recently become the proud owner of a Toshiba Laptop.(A Desktop replacement)
Someone told me that if I am mostly going to use it connected to the mains, then I should remove the battery to conserve it's life. Is this true?
Thanks in advance.

Hmm, I don't think so. Many people use their laptops as desktop but leave the battery in, does not appear to do any harm either to laptop or battery. On the other hand, many people take their batteries out - just personal choice I guess.

I leave mine in incase of a power-cut.

My laptop is 2 years old and like yours is a desktop replacement gaming machine. I have left the battery in the unit for its entire life. If you leave it in the system will keep it charged up which is what lithium ion and lithium polymer batteries like. NiCd and NiMh batteries on older machines need to be discharged regularly and fully to keep them working their best but todays laptops use lithium which means they do not need to be removed.

Ideally run your laptop down till it shuts down about once a month, this will help keep the battery meter on the system running accurate. The story of batteries needing to be removed is an urban legend based upon old requirements to discharge nickel based batteries from 10 years ago. If there is anything else you want to know about batteries feel free to ask.

Longer lasting battery
When you’re using your laptop from a mains power supply you should always try to remove the laptop battery if you’re not charging it. If you do leave it in for long periods of time it will discharge. The battery will be in charging constantly which in turn will result in a reduction of its lifespan. It will be capable of a finite number of charging cycles so only connect it to your laptop when absolutely necessary.

In addition, remember that you should run the battery down as low as you can before charging it up each time. If you’re working with a new battery pack then it’ll need to be fully charged and discharged before it works to capacity.

Hi Guys,
Thanks to all of you for responding. The trouble is I seem to have two different views as to what is the best thing to do.
Anyone else with an opinion on this?

It depends on your priorities - if you just want the battery to tide you over for short periods (up to an hour or so) then relax and use the machine as you wish.
It is possible to improve battery performance (charge level) by taking the battery through full charge/discharge cycles but these also wear it out - catch 22.
The exception is that most battery manufacturers recommend a full charge/discharge for the first 2-3 uses.
BTW - many sellers have laptop batteries at around £50 - some have better capacity than the originals.

To your Post yes it's true, Charge it to about 60% put in plastic bag and put in fridge, NOT FREEZER
