RV Battery
I have a 5 year old Interstate battery that needs replacing on my 5er. I suspect that it has been failing for a while. Plugged to 120 V it showed 4 circles. Removed the 120 V power and the RV battery ...

DOT requirement is trailer brakes must have good working battery in the event trailer/truck separate and THAT battery must supply FULL battery voltage for at LEAST 15 mins.
