That is very good. My MacBook 4,1 was in the 80% range at around 400 cycles.

I wonder why battery lifespan fluctuates so wildly. My battery has gone through only 8 cycles and are at 97% already ...

It's normal for it to fluctuate.

This should answer most, if not all, of your battery questions: Apple Notebook Battery FAQ.

Yes it is a very helpful article and it quashed some of my other doubts on the battery. But I actually meant 'battery quality' rather than 'battery status'. Even if the 97% reading is slightly inaccurate, my battery stands no chance to keep to 99% after 500 cycles as this guy's did. (I've been babying the MacBook ever since I got it and fiercely avoiding flash and intensive activities)

It is normal for your battery health to fluctuate, as stated in that article. There is no "battery quality" reading. Also, you don't need to avoid using your battery. It's fine to use your MacBook the way it was intended. Batteries last longer if they're used on a regular basis.

My battery is over 2 years old now (replacement Apple battery) and don't have near the load cycles you have. Weird.

Your battery qualifies for replacement as defective, but you no longer have AppleCare, so you're probably out of luck.

How would it qualify? This is the second battery it's ever had. it performs well as far as I can tell.

It's below 80% health before 300 cycles.

It's below 80% health before 300 cycles.

Oh ok. I'll try and remember that for my next battery.

Read the BATTERY LIFESPAN section of the FAQ link I posted.
