Yesterday I noticed a slight bulge at the bottom of my 39 month old 13" Mac Book White. Coconut battery tells me I got 4216/5450 capacity, battery load cycles 581.
Besides the bulge, I do not see any other problems, visually as well as in performance.
Is it time for a battery change?
Thanks Bear. Now to hunt for an iStore near me.
Is there anything like extended battery for Macs? If I remember Dell offers one. Normal battery lasts x hours, where as extended lasts x+ hours.
P.S. My battery was out of warranty by the time it boofed up, but I recall that they took off a lot on the replacement so it didn't cost a whole lot. I'm lucky to have two Apple stores in town.
You battery is less than 80% capacity; at that point it is worth getting a replacement, even if it doesn’t bulge. Though I am still using a Dell battery down to 59% capacity.
