Original battery discharged quickly and needed replacement.
No issues, followed the instructions. Back to normal battery life.
I used a strip of 3M blue painter's tape sticky side up secured to a piece of cardboard to place each screw as it was removed as well as the bracket/connector in the same orientation as it was on the bracket/connector. The tape holds everything in place, but it's easy to remove the parts. This way, no screws get mixed up.
