Hello,
For a week or so I have been having problems with my Macbook's battery.
Instead of usual 3-4 hours it only lasts 40-70 minutes. I immediately checked battery properties and it says that it only has 1769mAh...

You can see it on a screenshot here:

Sorry it is on Polish, but I am sure you can figure everything out

The macbook is from 2009:

Any suggestions will be appreciated.

Thanks!
