New battery for mid-2009 MacBook Pro
Back in May I upgraded my MacBook Pro with an SSD, vastly improving the performance. I've now replaced the battery, which was rapidly discharging under use. Fingers crossed that these two upgrades will now keep the computer going for a while.
I had previously replaced the battery in my wife's MacBook and I again went to The Bookyard for the new battery. I chose the Newertech battery, a new item, which is considerably more expensive, but I had read less than enthusiastic reviews for cheaper alternatives. Delivery was next day by UPS to a drop off point in town, this being the cheapest option. I have been very impressed with The Bookyard on the two occasions that I've shopped with them.
The battery was nicely boxed and came with the two screwdrivers necessary to remove the base of the MacBook and the battery. On this model there are only two screws securing the battery itself, so replacement is extremely straightforward. Following this you are advised to carry out a battery conditioning procedure, which involves fully charging the battery and then completely exhausting it. This calibrates the power management system, allowing:
- your new battery to achieve its fullest charge capacity.
- your new battery to reach its full lifespan.
- the system to accurately display the battery level.
This done, I now have a very capable mid-2009 MacBook Pro that I hope will provide a good few more years of stirling service.
