I want to buy a battery for my car. Something I can get from SuperCheapAuto in Sydney. However I'm not sure which one i can buy. According to this site: http://www.everybattery.com.au/lexus_auto_batteries.php I can get the Century NS70LX. According to this site: http://bestbatteries.co.nz/categories/car-batteries/battery-finder-passenger-4x4-light-commercial/lexus-battery.html I should get the NS70L Which one is correct (if any)? Thanks.

I hear a rattle when I start up the car sometimes. My car is a 2006 is250, 71k Km. Has anyone had this issue resolved? Which dealer did you get it fixed at? I'm a bit worried because it only happens once every few days so its likely they won't be able to replicate it. I did record it happening once with my iphone. Anyone know how much it would cost me to fix?
