I changed my E39 battery back in 14/12/2007, battery is original BMW battery. Today, the battery just died. When I used a volt meter to measure, it was only 10.8V. Couldn't start the car at all. Battery is less than 2 years old when it should at least last for 4years. I suspect over charging though I haven't tested it before, just a guess. Mileage of car is 199989km, M54B22, 2003 model.Question here is1) What is the voltage supply when car is running? Will it be more than 14.5V and more?2) Can I add a voltage stabilizer at the battery to stabilize the voltage?3) Anyone added voltage stabilizer to your E39 before?4) What's current cost of battery?Thank you bros.</p></blockquote><p></p>
