I bought my first Mac last spring--an early intel white Macbook, with upgraded RAM, Leopard and some other goodies. I recently bought my first (sort of) new Mac--a refurb 24" iMac, so that original Macbook did the trick of turning me into a switcher. But I have lately noticed poor battery life. Downloaded coconut tonight. It confirms my Macbook is 33 mos old. Battery has only cycled 108 times, but maximum charge is 46% of original. I assume that even though the charge # is low, the age is what's killing the battery. But, before I invest in a new battery, I guess I would like to be sure the problem really is the battery--is there anything else that could explain the quick (in terms of cycles) drain on the battery or anything else I should consider before investing in a new battery? I would love get another year out of this as a usable laptop--get me another 6 mos as my primary laptop until I upgrade and then my husband a few months to get used to using a Mac before he is ready to switch. After that I will plug it in and use it for my 6 year-old. Any advice would be much appreciated.
