Old Macbook Battery...welcome back, old friend!

My Problem

My black macbook battery was swollen and not keeping charge.

My Fix

"Out and In" (the old battery, the new one).

My Advice

If you have an old laptop, chances are you can still use most of its applications in the present. Parts are cheaper and you can leave your new "precious" at home and take the renewed one to work...or just outside with less risks.
