take it to Apple, they will replace it
That's an excuse. My digital camera batteries have 8 years (lithium ion) and they still hold about 60% of the original charge.
Suddenly, yesterday, the battery health went from 96% to 54%
Yes I calibrated regularly
I really hope your not comparing your digital camera batteries to a laptop battery. Two different animals.
They are different for sure but the battery technology is the same.
It really isn't the same though. There is no way a digital camera can stress a battery the way a computer can. Do you use your digital camera all day, everyday? I would think not.
I would try calibrating again, and make sure you do it the way Apple recommends. Many people don't understand that simply draining the battery and recharging is NOT the same as calibrating. The specific steps for calibrating a notebook battery are here: Calibrating a portable computer battery
GGJ,
calibrated as prescribed, at least 2 hours held the thing at 100%, than drained the battery all the way down, and after at least 5 hours of no juice, connected the MagSafe.
For last 10 days I am calibrating daily, battery health went up all the way to 89%😛, on 5th day, but dropped yesterday (after calibration) to 44%😎
😕
That is exactly what I did for year and a half, asDon't calibrate every day. You should only calibrate once every 30-60 days.
said, now I am just trying to revive 160 🙂eek:EU) All reliable battery information IS common knowledge, since Apple posts such information publicly. If your battery health is really 44%, there's nothing you can do to improve that. There are no "hidden secrets" that will restore health to a dying battery; only recommended tips on how to minimize depletion though proper use. All batteries are consumables, wearing out over time and use. That's why they're not covered by warranty, except in the case of manufacturing defect. If yours has reached the end of its useful life, replace it.

Have any idea beside common knowledge, no offense.😀
I've had 3 batteries in 3 years with my non-unibody MBP. The 2nd one only lasted about 6 months. This is why I'm not exactly thrilled with Apple's choice to go with internal batteries on the current laptops. Seems like my older Apple laptops had better batteries than my newer ones.
