Hello all,

I bought the original Macbook Air in about Feb of '08. Despite assurances that the battery would hold up, it's gotten to the point where the charge lasts noticeably shorter. Short enough, in fact, that I'm considering replacement.

The iStatPro Dashboard widget lists 197 cycles with an overall battery health of 91%. This is despite the cycle number being reset at some point with one of the firmware upgrades along the way. I suspect the real cycle number is around 300.

What are your opinions on whether or not it's worth replacing the battery at this point? Would the replacement battery show increased durability because of improvements in the tech over the past 18 months?

Thanks for the opinions.
