ED Life Expectancy

I just recently had my HV battery replaced at 13,500 miles on a 2016 451, under warranty. I am now curious as to what to expect for the life expectancy of my car. Is there a standard life expectancy for these cars? Or is it just a crap-shoot? I should note, I love driving the car and plan to drive it until it dies or becomes so undependable that it is not worth the effort.

Eight years of use on my two and I plug them in and charge them overnight to 100%. Actually a 100% state of charge is actually about 95% according to the test unit reading. Almost never any long term storage for mine and I keep an eye on the 12v battery. So based on things so far, I'll take my chances with my procedures. Hope to heck that I don't have to report back here someday and say, "I should have done this" or "I should have done that." :)

Could it be that your 12v battery is weak to the point where the HV battery is charging it even when the car is off? If that's the case then two things should be happening. One - your HV battery charge should be going down overnight a little more than would be typical. Two - the contactor to the HV battery would be on when it should be off. Our test unit shows whether the contactor is on or off. If it's on when you test the 12v battery, something is not right with the 12v battery. When we use our test units to check the 12v battery, we do it with the key in our pocket and just click on the door lock/unlock button. Typically if the 12v battery is reading that high, it means that the contactor is on and the HV battery is charging the 12v battery. Probably would be a good idea to take a multi-meter to the 12v battery itself and test it. Something doesn't sound right. Maybe that five year old battery needs to be replaced as you are saying?
