Battery charge lasting less than 8 hours.
Very straight forward. Took about 30 minutes. Instructions were clear.
Phillips screwdriver and spudger were included with the battery, so unnecessary expense buying separately. Getting battery out took patience to get adhesive to release. Cable #5 was tricky to reattach. Unfortunately did not solve problem. Still happy I have new battery and changing myself empowering.
