Dying Mac battery?

Message #1 - Posted 2012/12/20 - Brian Gordon

I'm on a MacBook Pro, late 2011 15", so it's not quite a year old. I don't run on battery very much, but when I do, surfing the net, I get about 3-4 hours of connect (WiFi) time before it peters put. Is this the best I should expect, or is my battery dying?

You should be getting at least twice that. If it's still under warranty, take it in for a check-up. If it's not under warranty, you might consider it anyway but you'll pay.

I bought a new battery that gets about that much time...but it was a cheap "after-market" variety. I suppose that's what I get for trying to save money.

I've rarely been happy with aftermarket specialized device batteries in cameras, phones, laptops, etc. I've tried a variety of brands from different vendors/manufacturers. Most had limited run time in the device, limited shelf life for a fully charged battery, and they got worse after only a few months. Definitely sucker good purchases!

Now I buy only OEM branded device batteries-- but from online vendors who discount them.

I was willing to take the chance because there are few times I really would need to run on battery power only. The original battery was 100% dead and I really just needed to have something in there that would hold up in case of a power failure.

An Apple Store Genius Bar appointment is the best bet for a checkup. They will not charge you for a diagnostic test even if it is not under warranty.

If it needs a new battery, you may have to pay for that.

Is the battery user-replaceable? It is not on the later MacBook Pro (at least not easily). If it is that way and it is not under warranty, the Apple store may need to send it out for repair. However, they should be able to do the diagnostic in the store while you wait.
