+900 MacBook Battery Load Cycles



Just wondering, but how rare is it to have a battery that lasts 3 times longer than the "rated cycle amount"? Apparently this battery should have been dead 600 cycles ago... I am finally now noticing a slight loss in overall battery life.



I have used this MacBook 100% of the time since the day I have gotten it over two years ago. Is this why it has lived so long?


Edit: The battery life just went up to 80%.

Its not rare and its not too uncommon. Most batteries die way before yours but it doesn't mean you have some super battery. It basically means you took good care of your battery and it's lasting a long time. Cycles are just a rating. Its not a must thing that happens.

Hmmm.
That is pretty darn amazing.
Mine died after 280 Cycles.
My MacBook wouldn't even recognize it anymore.
Fortunately, I had AppleCare.

Geez, you sure took care of that battery. And used the hell out of it! My original iBook G4 battery is nearing 400 cycles, and it only lasts about half an hour on minimum brightness.

I think what matters more with Li-Ions is age since production, as opposed to number of uses. Since your battery is only two years old, the battery shouldn't have died yet. Regardless, 900+ charges with that much power still left in the battery is an impressive feat. You must be taking care of it extremely well.

Care to share with us your usage habits? Do you calibrate it monthly?

With 900+ cycles, that battery must have been calibrated daily!

I don't think that's a correct reading though.... Coconut Battery can give some misleading information sometimes. Like the 51,000mAh battery.

Nice battery! I'm almost nearing 450 and got my MacBook last Christmas. Health is 91% (iStat) and it lasts me about 4 hours, depends what I'm doing But of course, I have it with me in school every day, so the battery is used nonstop

I calibrated it once about a year ago after reading the article on it...

Really, I just use this laptop nonstop, and have for the past two years. It never turns off (besides reboots). I am constantly cycling the battery; I will go right back to the charger when it gets low. Complete cycles is a very common thing.

I still get two hours out of it, although I am now finally taking the charger to classes with me even though I used to get away without it before. Just as a backup because it can get used up quickly...


Also in response to Coconut Battery reading it wrong: I have checked a few times a month and I have gotten a consistent reading. It was at 100% battery life up until the past few months...

Here is a screen from right now...

I believe that I have everybody here beat on load cycles... 5080, in 28 months. The capacity isn't so great though.

EDIT: I do not know if this is right... because last month, before my latest calibration, I had 2 load cycles... and I have not used my computer that much. Also, I had 37% battery when I took that screen shot... so I think it is wrong.

16 Months, 353 cycles, 91% health and it has hovered around the 90/92% mark for the past 70 cycles or so since dropping from 98% from the first 300.

If you keep it running from full to near dead and then charging it right back up they last longer than if you discharge slightly now and again and keep it plugged in. I have the Apple Battery Reminder set up (see their Battery page on the Support Site) and always do one proper 100-0-100 deep cycle per month. The recent drop to 90-92% I reckon could be because in the past month the MacBook hasn't spent more than three hours turned off per day.

Wow that's amazing! Who'd have thought the more you used the battery the better it was for it... Here I am trying to baby the battery and throwing it back on the charger when it hit 50%

I've got 964 cycles with a 95% battery. I just re-calibrated it since I did not believe the 98% I had 6 cycles ago. The battery still lasts 3-4 hours to a charge

Haha, I'm gonna say something's a little off there - there are around 840 days in 28 months, so unless you went through at least 6 cycles a day, every day, for the last 28 months, well, that seems a little high :P

I have the same problem. Oh well my battery lasted 600+ cycles. According to system profiler I am only 99 cycles into my new battery with 5469 mah. I replaced the old battery when I was unable to get more than 2 hours out of it.

Unhappy Advice

I'd like to know what am I doing wrong, since my battery healthy feels low adter just 19 weeks of usage

I usually try to fully drain the battery after charging it to full capacity. I've never calibrated it, I've just found out about it today.

I am currently facing battery problems because of the Lion upgrade. But I was already annoyed by battery life before installing the new OS. I barely could get 4 hours of a full charge. Maybe I should have my battery checked on an Apple Authorized?

From what I have read, the opposite is true of Lithium-Ion batteries. Optimal usage is to drain to 50% at most, then charge to full. At the very least, these batteries do not benefit from the full discharge like older rechargeable technologies.

My (second-hand) MacBook must have seriously been taken care of by a technology lover. She gave me every accessory I could have ever wanted when I bought it, and I praise her for being the nicest and most personable seller on eBay I've ever dealt with. We even caught up well after the sale, and I told her how happy I was with the computer.

Anyhow, my MacBook is 32 months old and hit 850 charge cycles. I think this screen-cap speaks for itself. All I do is charge it up to 100%, and use it, letting it drain until it shuts itself off. Then I'll charge it and repeat. I rarely charge it from a point where the battery is mid-cycle, or anywhere near.
