Ok, so new battery is now installed. I was after the Bosch S5 110D26L 680CCA 90Ah 160RC, however it is unavailable in OZ until September 2010. So I went with the following; Bosch S5 90D23L 650CCA 75Ah 125RC $170.00AUD. The only difference is it is only 240mm long, where the 110D26L is 261mm long. No real biggie. These batteries are for Camry, Aurion, Torago etc. The OEM Panasonic / Toyota Battery is only 420CCA.
