Hello! Anyone know if the Apple Store would carry a replacement battery for a 13" mid-2009 MacBook Air? Or should I get an aftermarket replacement from a place like fixit.com or OWC? The battery menu bar is telling me to replace the battery soon. I ran coconutBattery to check my current battery's health and it's at 75.2% with a cycle count of 682. Right now, I get about 2.5 hours worth of battery life on a full charge and I'm wondering if a replacement battery will get me a longer battery life.
