Contest: How low can your battery go? I'm talking load cycles, current capacity, and age. Mine has 312 load cycles and 22% capacity left. Lasts about 30-ish minutes unplugged, actually with my 6 year old daughter this is an automatic "computer limiter" as she plays webkinz, when the MacBook goes to sleep time to quit. I sure am cheap, cost of gas/etc has delayed me from buying a new battery, why should I, mine is 23 months old and still "works"..... Post image as proof.
