It's already here: <http://www.apple.com/macbookpro/battery/>
The battery improvements come in part from: using lithium polymer instead of lithium ion or nickel-cadmium, better chemical composition, and making the battery smart with a chip that controls how individual cells are discharged and charged, which greatly extends the battery's useful life. The last big factor is that by not having the battery in a protective case with a battery change door and mechanism, etc., you can put in a lot more battery for a given weight/space. I know other ebook and computer manufacturers are moving to Li-poly, they may also do adaptive charging/discharging as well, but as long as they are wedded to making the battery removable they will lose to Apple on either capacity or weight. My son has a newer MacBook Pro with the built-in battery. I have a slightly older MacBook Pro with a user-replaceable battery. His laptop outlasts mine by quite a bit. If the advertised 7-hour battery life is an exaggeration, it isn't by very much. > From: mike <xha...@gmail.com> > Subject: Re: noPad4me > > I mean in mac laptops. > > On Mar 16, 2010 10:24 AM, "tjpa" <t...@tjpa.com> wrote: >> >> On Mar 15, 2010, at 9:05 PM, mike wrote: > > When do these new batteries get >> into laptops? >> Not for you PC boy! ************************************************************************* ** List info, subscription management, list rules, archives, privacy ** ** policy, calmness, a member map, and more at http://www.cguys.org/ ** *************************************************************************
