5 years in, 5 years to go
Well, I did not have an actual problem it was just that the battery that I have had has already passed the 1000 cycles mark which means it can no longer hold the same charge as it previously could. I was still getting a decent usage time of 3+ hours. But I just decided that it is about time to change the battery and at the same time save money while doing so - I live in Dubai, UAE where it would cost around double the amount of buying it from iFixit and take around 5 working days to do it, which is just ridiculous.
The replacement of the battery went very smoothly as you can see from the video attached, no challenges whatsoever. It took me around 8 minutes to carry out the repair I just used time-lapse footage to compress it for the viewers pleasure as well as the site's restrictions.
Since I have already given my Mac some hardware upgrades along the way 1. 16GB (2x8) Corsair DDR3 1600MHz RAM 2. 500GB Samsung SSD 840 EVO. I thought that it would be worth it to replace the battery to further extend the life of my laptop. So in other words only replace the battery if it is actually damaged or you already have invested in valuable upgrades and you would like to keep the laptop. I bought my Mac in March of 2011 and just replaced the battery in hope for another 5 years!
