We recently sold our 7 year old Airstream trailer. It came equipped with Lifeline AGM batteries. After reading a lot of information on RV Converters, I replaced the cheap crappy converter that came with the Airstream a few weeks after we got it. I replaced it with an IOTA DLS-55/IQ4. The IQ4 part is important. Our trailer spent a lot of time on shore power as it was plugged in even when stored. So, a high quality converter was necessary to save the batteries.
IOTA Product Specifications
The batteries were still functioning as new when we sold the trailer.
With our motorhome, I plan to make the same swap, but i'm not in a big hurry because apparently the batteries are substandard also. However it will get done in a few months.
