When to replace good Macbook battery?

post #1 of 5
Thread Starter 
I have a late 2007 Santa Rosa 2.0 GHz Macbook. It's still on its first and only battery and that battery is still working just fine, after 3+ years.

I have noticed, though, that the battery is swelling: the outer side is definitely convex, such that it grounds on a flat surface and the little bumper foot nearest the battery cover is lifted off the surface.

Time to replace that battery? Again, I emphasize that the battery is still performing fine.

If the slight swelling doesn't bother you, why replace it if it works fine?
Now, eventually it's ability to hold a charge will drop off sharply...
From out there on the moon, international politics look so petty. You want to grab a politician by the scruff of the neck and drag him a quarter of a million miles out and say, "Look at that!" -...

Replace it before the swelling cracks the case, as it did in my own case. Once the case is cracked, you've lost a lot of resell value.

I've never seen an official cycle count for when you should replace one. Mine jut hit 1100 and has started showing signs of needing replacement. (It just started shutting off/dropping all power once it hits about 20% gone).

Bad luck.

I have called Apple, which says that a swelling battery is not a recall issue -- i.e. they won't give me a free replacement -- but they say that yes, a swelling battery should be replaced before it damages the macbook. And of course they offered to sell me one.

I see that third-party batteries are a fraction of the $129.99 price Apple wants for its own A1185 MA561LL/A battery. Do we think it is worth paying up for the Apple battery?
