Do I Need Battery Replacement ?

[matelot]

My Gen 1 MBA battery performance has become ridiculous : 95% to zero in like less than 3 hours.

Where can one get battery replacement and how much would it cost ?

thanks

Try resetting the SMC. Also, look at the BATTERY INFORMATION and BATTERY LIFE FROM A CHARGE sections of the following link. This should answer most, if not all, of your battery questions:

Apple. But there's probably nothing wrong with your battery.

My brand new 11" is the same. The battery in this thing is actually worse than in my 5 year old laptop... I can just watch the percentage go down even though the brightness is at the lowest possible. Really disappointed.

I can just watch the percentage go down

It is generally accepted that if your laptop is not plugged in and you sit there looking at it with the screen on, the percentage will not go up.
