Battery is over 7 years old. I have it out of the car and have been Milton load testing it and charging it but I've misplaced my battery hydrometer. It was reading a bit low at 12.2v, but it's up to 13+ now. European cars (BOSCH?) like my 83 audi and 95 Volvo never seem to keep a battery fully charged, base on the fact that I can throw a batttery charger on and it takes 10 minutes for the green light to go on. My 89 Dodge, 84 Ford and 2000 SUBaru get the green light on the charger after only 1 minute. I tend to get extra time out of a battery due to charging top ups. I have an battery in my 83 Audi that is 14 years old. The 850 battery now passes the Minute after test on my Milton charger but at 12.2 Volts it was already close to the fail area for that test. I had always purchased my batteries from Volvo , but now it comes up as DISCONTINUED. My Volvo dealer claims to have the battery though - but the price is $170. Would be nice if it's just the battery. I thought you could drive a car with a dead battery though.
