I’ve recently started noticing that the battery on my Macbook loses its capacity very quickly.  I think it’s at about an hour to an hour and a half limit.  It’s sad to see.  I had such faith in it.  I was so diligent to only plug it in at about 6-8% remaining power, often waiting until I received the second reserve-battery notification for its depleted state before connecting the power cord.  I consistenly let the Macbook discharge then recharge, but alas, it hasn’t been holding its charge.  I realize that all Lithium batteries have an end-of-life.  After a few years with this fine piece of machinery, I do believe its lifeline has finally given up.  A replacement battery will run me over $150, but what pains me more than the cost to my pocketbook, is the cost to the environment.  Another Lithium battery to add to the heap.  My reserve battery notification just alerted me; time to plug it back in.  Sigh.
