Getting another New Battery for my MBP

January 27, 2009 by debbie T | Computers • Mac Corner

Well, I spoke too soon. I was bragging about the increase in battery capacity after I received my Macbook Pro back from Applecare after my logic board repair.

When it was sent out, the battery capacity was @ approximately 63%; when I received it back (Jan 9) it was raised to 89% capacity. hmm, very curious. I thought maybe I got a (different) new / refurb battery back by mistake. I was happy to gain the extra capacity, so I wasn’t complaining!!!

Well, by Jan 23, it was back down to 64% capacity, and down to 50% this morning. I even tried calibrating twice with no luck, it actually got worse.

So, I figured I better phone Applecare before I ran out of time. I received my current battery as a replacement in April, so I didn’t want to wait too long.

What a pleasant experience. I am getting a new battery sent to me! Yay! The Applecare rep talked to a tech specialist, and they seem to think it might have drained due to the problematic logic board which was replaced (or maybe the bad Nvidia card). I don’t care what the reason is, I will have a happy Mac with a new battery.

UPDATE Sunday, Feb 1: Got my new Macbook Pro battery on Friday. I installed it this morning, making sure to shut down my MBP first, and unplugging from the charger. After I installed the new battery, I plugged it in, then rebooted.

Once I booted into OS X, I saw that the charge was @ 59% I launched Coconut Battery to check the data. 100% capacity @ 5563 mAh.

I will not remove the power cord until it’s fully charged at 100%. I will probably calibrate it tonight or tomorrow.
