Hi Members,I'm new to Malaysia and pleased to be a member here. Came across this forum while browsing for information on replacing the batteries for my X5 E53 2006. Bought this X5 here last month and notice that the existing battery drains out very quickly. Never had this problem with my old X5 that I used in Melbourne, Australia and so I'm advised to replace it before it causes other issues.A bit about myself. I'm 50+ yrs of age, male and love to keep my cars in perfect nic. A big fan of the X5 and like to meet people who are willing to share their experiences in quality care for their vehicles.Thanks for letting me in here and I look forward to contributing my bit.RegardsFazlun
