Battery issues

[CNG]

It seems I have recently been having problems with my macbooks battery so I thought it might be a good idea to try and get some advice on the matter. So hi my name is Chris

The problem I am having is that my aluminium macbook will randomly cut out even when the battery will have a good 50mins left on the counter. It will not give me any warning and once plugged in it tends to start up without problem. Sometimes I will know it's fully charged (the battery indicator on the side backs this up) and it won't start up without being plugged in. The current readings from istat are...

Health: 41%
Cycles: 361
Charge: 99%

The warranty on it was a 1 year standard which has now ended with it being nearly 2 years old.

Thanks for reading, any advice?

Chris

Have you calibrated properly?

Yes, I tend to calibrate it whenever I get the chance which is usually every 3-4 weeks (and the initial calibrate on purchase). So it would seem that I am best to call apple and see what they say, as I thought the battery would last longer than this

I don't know that they can help you with it. The probably can if you make a scene in the apple store, but that may be the only way. The batteries they used before the 1000 discharge cycles were only rated to 400 (I believe?) If this is the case, 361 may be too close for their comfort, and they may reject your claim. But give it a shot man, it gives you a good excuse to look at all the beauty in the apple store

While you may get someone to make an exception, it's not likely that they will do anything out of warranty and without AppleCare.

For Apple notebooks with removable batteries — such as previous generation MacBook and MacBook Pro computers — a properly maintained battery is designed to retain up to 80% of its original capacity at 300 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs.

The built-in battery in the new 13-, 15-, and 17-inch MacBook Pro is designed to retain up to 80% of its original capacity at up to 1000 full charge and discharge cycles.
