Customer Reviews

Not an "Apple-to-Apple" replacement
This battery definitely did not meet my criteria as a suitable replacement.

On the plus side: as near as I can tell, it did actually store electricity and allow that electricity to be used to power my laptop. And after all, that's pretty much the bare minimum a battery ought to be able to do and still be called a battery.

On the negative side: the fit-and-finish of this battery was awful. Something minor like the slightly-different LED status lights (no diffuser to reduce glare, simple on/off rather than Apple's industrial-engineered "fill-up" animation) can easily be overlooked. After all, that has no effect whatsoever on the actual performance of the battery.

But other issues did. The first battery that was delivered to me, the status button wasn't even operable; it was stuck in the "on" position. A replacement battery shipped to me, the button fell off upon opening the package and had to be re-glued. Even after that, the button didn't rest flush with the battery case, causing it to scrape on surfaces (my lap, the table, etc.) that the computer was sitting on.

Operationally, there were also problems with the compatibility with my laptop. The computer never would recognize that the battery had reached a full charge; instead, once the battery got to 100%, the charging would cycle every few seconds between "Charging", "Calculating", and "Charged", with the green/orange power cable light toggling back and forth as the status changed.

Note: I did perform the recommended battery calibration _and_ reset of power management for the computer. The above behavior happened in spite of that.

Also, it appears that the battery doesn't support the Mac OS X Battery Updater, as inspecting the battery status in the System Profiler showed null ("0000") values for the various firmware revision fields. I suspect that may be related to the inability of the charging system to recognize that the battery was fully charged.

After the second dud, I sent the battery back for a refund. For those on a really tight budget, you might find the various annoyances acceptable. But frankly, I'd say those on a really tight budget ought to be buying a computer that doesn't chew up batteries after just 12 months, and doesn't have a battery so expensive that at $75 the replacement seems dirt cheap. Conversely, if you feel an Apple fits in your budget, you might as well accept that you have to spend another $130/year on batteries.

Not perfect but inexpensive and works fine
I bought this to replace the aging battery in my MacBook Pro. As other reviewers have noted this is not an EXACT replacement of the original and some discrepancies do exist. However, it does work just fine. I've had no issues with battery life which seems if anything superior to the old battery's performance. If you don't care about a perfect fit and seamless seams, this is a great battery.

fits loose but works
I have a MacBook Pro. This battery works great & was much cheaper than one from Apple. This one clicks in just fine but fits just a tiny bit loose. I have been using for months & it does not seem to be a problem. Not worth the savings if it damages the laptop, but so far so good. Will report back if I develop issues.
