Have you ever heard of cleaning your laptop battery to make it last longer? I never have. The only thing I have done, is take out the battery and clean the dust around it. But there is a way to really clean it, to make your battery more efficient.  In order to do this, take out the battery and find the metal contacts. Grab rubbing alcohol and use a swab to clean the metal contacts.  It's that simple. Make sure you do this every month and also allow it to dry before re-inserting. PicBy[jadijadi]
