Reviews for Rechargeable Battery - 17-inch MacBook Pro

It wouldn't be so bad that these batteries don't last half as long as they should if they aren't twice as expensive as they need to be. I did buy a desktop model for my new computer, but I have to overpay for another battery to sell my MacBook

Battery bulged... not much more to say. The computer is useless when I have the battery in because it's bulging so much that it is effecting the track pad. When I rest my wrists to type all of a sudden the computer randomly clicks on things. I believe this is actually a hazard to the user.

The Apple Store just replaced my second battery at no charge. Thanks to Apple for the great service, but this shouldn't be happening. I've have had several Apple laptops beginning with the PowerBook 100, this is the first one to have so many problems. Hopefully, the newer MBPs are more reliable.

I have to type this on someone else's PC because my battery dies when it hits 94% charge. This started happening a handful of days ago, and now the battery is physically expanding at a rapid rate. Basically my laptop just became a desktop, which is especially great for someone who works on the go. This is the second battery I will replace in less than two years. As I mentioned in the title of this review... I LOVE my MacBook Pro, but COME ON APPLE - make batteries that support your machines!!!

I love my mac, but the battery ---very poor----this is the third one i have purchased

Always have loved my macs but have had to replace this battery several times. at $130 a pop, it really strikes as gauging us. Man, gonna have to consider something else. Can't just keep afford to throw money at problems.

Battery bulged and now won't hold a charge. Again.

Our company has purchased over a half dozen of these batteries to replace those that bulged. One expanded so quickly, the user reported that her laptop had "jumped" on its stand. Our company's IT department views this battery as a safety hazard, and we're glad we finally phased the last of them out.

My 17" Macbook Pro battery was working fine, however it has always gotten hot enough to burn me. ---All of the sudden, one week ago, the bottom of the battery started bulging out (which I assume is due to the severe heat)---Only the SHARP, ALUMINUM bottom-panel, corner edge of the battery is sticking out. This happened literally overnight and I discovered it when I placed it on my lap, and IT SLICED ME OPEN!!! It is as sharp as a razor blade!!! Dangerous! I need to talk to someone about this ASAP.

I discovered this morning that the battery for my 17'' MacBookPro4,1, had bulged significantly, a good 10mm (on the power chord end), and while still functioning the laptop no longer sits even on the table but rocks. Guess I'll have to replace it.
Battery Health Information:
Cycle count: 166
Condition: Normal (? ... really!)
From reading other info I gather the battery life should cycle to 300 before loosing stamina. And of course warranty is way beyond claim unless it goes on the cycle count.
So, what's happening here Apple, the computer didn't eat that much over Christmas? Is it safe to continue using the battery?
If anyone has any further advice, I'd like to hear from you.
I've been an Apple fan and user all my computing/work life nearly 20 years now ... this is, however, a concern, as I do rely on my Mac for work.
