MacBook Pro 15" (Mid 07) Battery Not Lasting

[TheTosh]

Hi there.
Beginning of this Year my battery had not been lasting as long as i thought it should be. well now a few months ago, My battery will only last to 80% then my computer will die.
Health: 18%
Cycles: 62 (Yes 62 Cycles)

What can I do about it?
I live in New Zealand if thats any help.
Thanks TheTosh

its over 2 years old and only 62 charges? Sounds like you ruined your battery.
If you don't use it, it'll go bad.

Did you try calibrating your battery? search if you don't know how

edit: reread your post. (thought you said 80%, not to 80%) anyway, try calibrating it. also, check your battery's health information (apple->about this mac->more info->battery) and under health information, what does it say as condition?

If you’re covered under AppleCare, they may replace the battery for free.

If you’re not, then you’ll probably have to buy a new one.

Batteries simply die, and if you don’t use it enough, it contributes to its death. Use it or lose it.

I would've like to use it more but it keeps cutting out on me.

I just changed battery, three months ago. 607 cycles in 28 months. It had 58% health.
My new battery is now at 95% at 90 cycles.
