Hey all, was looking through some threads about battery health and the such and decided I would check out my istat pro widget. Anyways when I went and check it is says that my battery is at 46% health! I guess I must have used it a lot or somthing! I have calibrated the battery many times and only charged it 239 times.... I purchased my macbook a year ago, and about 6 months ago I was having issues with the battery (the plastic was peeling away on it, at the edges and I was sending my macbook in for repair (forget what went wrong) I think that they replaced the logic board or somthing... anyways I sent a note along with the macbook telling the support people about the battery and they sent a new one back with the laptop. So I have a "new" battery and it's already this low. So, do I need to get a new one?
