Battery Coming Back To Life-But For How Long.

[Annie Bynnol 612]

A 5 year old laptop has been out of use for two years partly due to a dead (not charging) battery.

 

Today I re connected the charger and as before its working fine.

I am currently updating the software.

I appears to be recharging the battery-currently at 15%.

 

Is there anything I can do to help the battery recover? Or is it a lost cause?

 

Edit: Microsoft Surface API-Compliant Method Battery is updating has just started.

Even new batteries often only have a 6 month warranty, due to the chemical composition of batteries, they can degrade, and if not treat right they can fail after only a few months...

it might work after a rest, might charge - but it will discharge fast, and wont last too long....

So can you advise on the best way to treat a Laptop battery right please. ?  Thanks.

Don't leave it plugged in and charging while using it, once it's hit 100%, unplug it and discharge to around 30% before charging again.

If you need to run it on power for extended periods, remove the battery (if possible)

don't over-charge/leave 'full' and still charging (batteries do have protection against this, but it's still good practice regardless)

don't let the battery totally drain to 0% before charging again.

don't expose to sudden temperature changes.

 

don't shock/hit/bend etc the battery (common sense, but you know, even accidents can happen...) - picking up your laptop wrong (especially if is very thin) can cause a slight flex - and can some times cause problems for the battery or it's connection(s)

Anything else is your general common sense stuff (don't get it wet, don't use wrong chargers etc)
