For members in Melbourne Australia, Just wanted to share with everyone my experience regarding a battery replacement for my X5. To put it simply BMW wanted $455 for the battery plus $110 to initialize it. Naturally did some research and found a Bosch battery designed for european cars which is perfectly suited to the cars specs regarding dimentions and CCA 800 for just $275 (part number 60038) including a 15% discount fitting inclusive. The company is HOLLYHOCKBatteriesPLUS located at 35 Yarra Street Abbotsford Victoria 3067. Check out their website. Anyone interested is eligible to receive 15% discount when you mention this forum. Excellent service!! Very happy...All the best.
