Laptop Battery

[Maydup]

I have used my laptop for hours on end with it plugged in to the mains, thinking this is the best solution to maintaining power and not having to rely on the battery charge.

Now the laptop is tending to get hot quickly and the battery life is short.

Have I likely ruined the battery by using the laptop with it plugged into the mains?

I did the same thing - when my battery was fully charged, I kept forgetting to unplug it.
Eventually I ended up with a battery that wouldn't hold its charge and ended up needing a new battery :(

It might be nothing to do with having it plugged in. Laptop batteries don't last long anyway in my experience.

Laptop batteries should be charged to a maximum of 80%. In fact, most modern laptops feature what is known as "Battery Life Extender" mode which allows you to keep it plugged into the mains but not to overcharge it:

I definitely don't have a battery life extender as mine charges up to 100%. The battery life is annoying but the overheating feels a bit alarming so I best look at replacing the battery I suppose.

Any tips? Its a Dell Inspiron 2 in 1. About 2 years old.

Yep the battery is definitely overheating and not holding charge for very long.

Any tips on where to buy a new one? Prices seem to vary so much. Nervous of the very cheapest online but would feel a fool if I paid too whack unless I need to.

Hi Maydup
I had to replace the battery in my chromeback last year and following the usual great advice from Buenchico bought a new battery from :
laptop-battery.org.uk
Very reasonably priced and very helpful. Good luck.

[Maydup]

Perfect thank you so much FBG40 just what needed.

[Maydup]

Oh no .... that website doesn't seem to exist.

Could it be .co.uk? There are so many sites with very similar names.

I just tested and was able to access it at laptop-battery.org.uk
Copy and paste it in just to be sure its typed correctly

[Maydup]

Thanks it works now!

Can I ask how long your batteries are lasting. Mine is 5 years old. Is that good?

[Maydup]

My laptop is about 2 years old Ladybirder. But I have probably killed the battery this week as we watched Golf on it for three days solid with it plugged into the mains.

[aelmpvw]

i thought the battery stopped charging once it was 100%?

[Maydup]

Well its bu33ered whatever has happened to it!

I'm struggling to find a new battery for my laptop. Anyone feel like searching on laptop-battery.org with me?

I need one for a Dell Inspiron 7931 2in1 laptop.

[barry1010]

Is that the right model number?

[elliemay1]

Did you mean 7391?

[Maydup]

7391 its the heat!

[youngmafbog]

No, leaving it plugged into the mains is not a problem, otherwise the millions of laptops used by business would have a problem.

And they dont.

I've found this one on Amazon

which I think is the same as this one on the other site for £30 less
