2009 MBP Expected Battery Life Cycle

[Woodbags]

Can anyone shed any light on how many cycles I can expect out of my battery? The machine still works like a dream but I checked the other day and realised I'm on 450+ cycles.

I have an ipad which I can/should use for browsing in front of the tv but I still prefer my MBP. If I knew that my battery was 75% through it's expected life I'd probably favour the ipad for the minor stuff and save the MBP for when it was really needed.

It's unofficially rated to keep an 80% charge over 3 years or 1000 cycles.

All unibody is suppose to be 80% charge with 1000 cycles as stated above.
And 2009 model is unibody so you can see about 1000 cycles.

Thanks guys. Good to know I'm well within lifespan.

It's not like I have to rely on the battery but on my old MB the battery died and it couldn't survive without being plugged in.
