The old battery was OLD... and not holding a charge.
Easy. This model (2008 aluminum) is designed for having the user replace the battery.
This is an aftermarket replacement battery, NOT an Apple OEM part.
This part only works in the A1278 MacBook. It will not work in a A1278 MacBook Pro even though the model number is the same.

Old battery (original) had gotten swollen (interfered with trackpad) and it didn't hold a charge.
I opened the back (push on the simple lever/tab, pull off the panel) and inserted the new battery. I replaced the panel and it was done. Easy!
Battery was partly charged. I let it charge fully overnigh . . .
My cat walked on my Mac-book and it crashed on the floor.
The screen broke in the meddle and the Apple store didn't want to repair it because too old (for them).
I fixed it easily following the photo-sequence of iFixit web site,
However I suggest two improvements:
1. It's not necessary to use the Hea . . .
My battery was dying. After 6 years of loyal service.
So easy. The early MacBook made it easy for the battery to be replaced. Happy and I think this MacBook can last me one or two more years. Time to start saving up for the next one =)
Take care of your electronics equipment (name it!). It'll save you . . .
My Macbook unibody alu, late 2008, has a good 6 year on the back. A few years ago, i changes the HDD and screen unit, since it was going bad. Now the fan was started to sound like a jet engine and it was running slow, plus the battery only lasted an our.
I Ordered a new SSD, plus a dummy for my Supe . . .
Basically, because I was bored with the old system so I upgraded everything and I finally had the time - literally jumped from snow leopard to yosemite! It started with installing higher ram then figured out it was easy enough to install not just a new hard drive but a dual one. Thanks to you guys w . . .
Cracked screen of course
The repair went well all the way until I tried to use the home button on the new display assembly only to find that it wouldn't depress, which made me depressed.
So I opened it up and the button would depress. Clicked it back in and it would work with needing to be depressed . . .
