Re: Battery.
Yes, the price on the battery was quite good. Considering that the last time I bought a battery it cost me $80 I was quite happy. However, I am not expecting much. It's a generic Made In China battery and if it lasts six months I will be happy.
Mobile power is not why I bought it though. The MBP I just bought comes without a battery. The seller was nice enough to include a charger in the auction so that could have been the end of it. But I have an issue with toting around a laptop that has a giant hole in the bottom. Not to mention that moving it would require shutting it down first or the Mac would just shut off when I pulled the cable out.
I tend to take chargers with me in the places I take my laptops because I am usually there for awhile and those places tend to have plugs. I want however to be able to close the lid, disconnect the Mac, transport it and not have to reboot it. I don't turn my Macs off.
I can't do that without a battery. Since even dead batteries (by experience) hold enough of a charge to allow sleep for the limited amount of time my Macs tend to sleep it doesn't really matter to me if the battery is superb or not, just that it can hold a charge long enough to support sleep between extended periods.
Now if this battery turns out to be really good, so much the better, but I just need a solution that fixes my particular 'problem' - and that's why I was ok with a generic no-name battery for $20.
Not that I needed to explain this, but if no one around here has figured out yet that I tend to make long posts over miniscule things - well, now you know.
