Battery cycles

[Hazzarell]

Hey people.

Just a quick question. My Macbook's battery has done 902 cycles and is on 92% health. I was just wondering - even though I know it's impossible to predict the life-span of a computer battery - a) how accurate that reading is (I use the iStat Pro widget) and b) ignoring the health reading, is it time to buy a new battery when it hits 1000 cycles?

The health has gone down from 100% to 92% in the space of about 3 months? Maybe more. Is that a sign that I should change it?

Thanks in advance.

Honestly, I bet you get another good year out of your battery!

First, if you haven't calibrated properly, your readings may be off. Second, as long as your battery is working, there's no need to replace it, simply because it has a certain number of cycles on it. Your battery health will fluctuate over time. It's normal.

1000 cycles... you guys are spoiled.

My lowly 2008 model needs a new battery every 8-9 months.

Wow. That was quick!

Thanks guys. I'll have a read through of that FAQ.
