Battery Failure/Health Disappointment - What should we do?

[ddk121]

After the 5 hours, does it matter if the sleep light hasn't gone off, and is still flashing?

Hmmm, that I don't know about. I might wait a little longer just so you get as much power out of the battery as possible.

Didn't affect mine.

Keep using it and let us know in a week.

Guys in need of some help. Macbook is on 82% charge, and is saying '1:40 until full". Surely it can't take that long! Is there anything I can do?

That's about right ddk121. These batteries charge pretty rapidly to about 80% capacity and then do a trickle charge for the last 20 % that could last several hours.

probably has a bit to do with the 45watt adapter...

anyone try hanging their mba off the side of a desk and plug in a mb pro adapter? I'd be willing to bet it'd charge a bit quicker, anyone able to try?

Pheww, I thought it was just me So does everyone's MBA take around this long to go from 80% > 100%?

Sorry to be a pain, but is it ok to leave my MBA charging overnight?
Also, I am albeit worried about my MBA. The battery health is at 94% already, and I fear about the charging times it is taking to charge...

Just keep using it and cycle through standard charge cycles. I think that resetting PMU is being done way too much. Mines on 21 cycles now and I went crazy resetting, conditioning, obsessing for about 13 cycles. Finally just gave up and used it like normal and battery has been up to 97% for past 3 cycles and seems to keep getting a wee bit better as I use it.

Woohoo! 98% cycle 22. BTW, it didn't start getting better until after 10.5.2 update. I'm lovin' the extra 4-5%.

Mine's at 89% right now with 57 minutes to charge.

Yes it is fine to leave it plugged in overnight. It will not hurt the battery or computer to leave it plugged in.

I got my mba yesterday and it charges in just a few hours. However, there is something going on with the battery. From being fully charged at 100% it drops amazingly quickly to 90-95% in just a minute of use. It starts by showing around 3.45 of time left, then drops to just over an hour, then jumps up again to around 3.30. There's something wrong, but what I don't know. Let's hope Apple releases a software/firmware update for these battery issues.

This thread is so full of utterly misconceived and wrong statements about LiIon batteries that I will let this link explain the true nature of how to use your battery properly:

MY BATTERY IS FIXED!!!

Sorted itself out eventually after a few conditionings. Now takes around 3 hours to charge from empty.

That was my only disappointment with the MBA. Now it's seemingly ok I'm delighted again.

Very quiet, no fan noise, no HDD click, more than enough power for my laptop needs, great even screen with no dead pixels, cool as a cucumber temperature wise..

I'm in laptop heaven at last
