Battery replacement for mid-2010 15" MBP

My Problem

The original battery lasted almost four years, so I can't complain! However, it was obvious several months ago it would need replacing soon.

My Fix

It was a piece of cake to replace this, thanks to the original replacement battery you offered, and the tri-Y screwdriver you suggested. (No thanks to Apple for making this harder than it needed to be!)

My Advice

The new battery has been through a couple of charge cycles and seems to be doing quite well. I am hoping it will last me another few years or more, giving me more time to get my usefulness out of a great MacBook product.
