Is it correct to remove battery from New Laptop

xxxdarlingxxx

Hi there

I have just ordered a new laptop and was wondering if it is correct that in order to "protect" the battery I should remove it from the laptop when I am on mains power.

The laptop I have has always had the battery attached and is lucky to hold more that a 10 min charge after 3 years.

Any advice would be great.

When i brought my first laptop a few years back nobody told me about battery problems if left plugged in all the time but i soon learnt after about 9 months when my battery died and would'nt charge. Since then i charge my battery and when its charged remove it from the laptop some people say you should'nt leave a laptop battery charged but as i use mine on mains and so i can go portable i dont really feel that appies to me. Basically if you leave the battery in all the time its plugged into the mains , you'll need to replace it in about 7 months but i'm no expert just personal experience.

Thank you sei1925 that's exactly what I was told.

If your`e using the laptop on mains most of the time it`s best to take out the battery and leave a 40 - 50 % charge in it.

Put it back in every 3 weeks or so , run it and then charge it fully, use till it hits 40% and take it out again.

I must admit that I've hardly ever removed the batteries in the three laptops I've owned (Toshiba, Acer and HP). I also admit that I rarely run on battery power. However when I do I haven't noticed any particular change in battery performance.

I've never seen that "store it at 40%" theory before, and I don't think it's right - or at least I can't think of a reason why it could be.

From a bit of internet research, the answer depends on several factors, including what type the battery is and how "intelligent" the charging circuit in the laptop is.

Assuming it's Li-Ion (most are these days), there seems to be reasonable agreement about the following:

1. If it's a "dumb" charger which tries to charge the battery all the time, do as suggested and remove it when on the mains.
2. If it's an "intelligent" charger which only tries to charge the battery when it's part-discharged, leave it in when on mains.
3. Try to avoid fully discharging it too often.
4. Store it fully charged, and remember to top it up every couple of months.
5. Keep it cool in use and when stored - in general, the higher the temperature, the shorter the life.

[Edit: If you choose to do 2. the battery will probably not last quite as long as 1. - but you do have the advantage that if you get a power cut you won't lose what you've been working on!)

Aha yes I`ve had that a few times, Nightmare. I`m using a ups now, only get about 10 miniutes but worth it for the sake of £30 or so.
