Re: Upcoming Cars Speaking of Mazda: Mazda's i-Stop system requires special battery | TopGear.com.ph But apparently, the system comes with a special requirement: It needs a higher-quality car battery for it to operate seamlessly. The regular batteries that we normally use on typical cars just won't do. ...replacement battery would cost P14,703. Actually, the price would have been more expensive--around P25,000, they say--if the batteries had been sourced from Japan This is something to consider when looking at the models with i-stop. Mo tech. Mo problems.
