The Harris batteries that came with our 2017 ACE 30.1 lasted maybe 6 months. Actually less than that, but it took me that long to replace them with a pair of Interstate 6 volt batteries, and gain about 50% over nameplate capacity. The batteries would draw down to 12.1-12.3 volts over a few days of just sitting in store mode. The Interstates have been great for the almost 2 years we’ve had them.
I also got rid of the WFCO converter that came with the coach and replaced it with a Progressive Dynamics. If you attempt to invoke a warranty with Harris, they will refuse it and blame the battery failure on the WFCO converter.
I also have added a Bogart Trimetric battery monitor and a Bogart SC-2030 solar charger (200 watts of panels on the roof and another 120 in a portable). The SC-2030 keeps the batteries full and performs a proper equalize sequence.
