Doesn’t look good. What did I do wrong?

Will buying a new battery even solve my problem?

I think your battery support less than 235 charge cycles and now its done You should replace your battery.

If you are not traveller and stay on the desk then you can keep this battery and plug the AC adapter.

Thanks. I’ll replace it. That’s funny that Apple would have replaced my battery with one that had such a short life span. Wait. Funny? No, tragic. It went kaputt as soon as the warranty was up. Figures.

Under Heath Information it states that my condition is Check Battery. What does that mean? Thanks.

There is something wrong with the Macbook battery. You should talk to Apple support for this, they may change your battery if its under warranty.

I charged my battery 100% on my macbook and then went travelling and left it at home for 6 months unattended- returning home my battery was dead- subsequently I’ve read I should have only charged to 50% – anyway I can salvage my battery??

nick June 8, 2012, 4:51 am

Is it good for my battery if I just keep it plugged in most of the time?

David June 14, 2012, 4:20 am

Nice article. One minor quibble: “mAH” stands for miliAmps times Hours (not per) and is a measure of power.

David June 14, 2012, 4:21 am

Sorry, that should have been energy.

Joe November 19, 2012, 3:20 am
