More battery basics.
Good Day, I have a few questions Is it better for a deep cycle camper battery to be kept in a constant state of fully charged using a better tender, or better to let the battery slowly drain low,...

Many older converters held 13.8 volts and that is a bit high.
The 12 Volt Side of Life
OK, so if my camper converter with the battery switch on is supplying a constant 13.2, that is OK to leave on for weeks on end?
I went through two Interstate batteries in one year doing that? I'll try it again and make sure it isn't feeding the batteries more than 13.2 0r 13.4
I think we've already established that many owners are supplying charge continually with success.
The demise of your previous Interstate batteries may have been because you were reluctant to keep them charged. Left in a depleted state, they will sulfate and then will be going to the battery hospice.
FWIW, I have five batteries in two banks. Both banks have been charged daily with a temp compensated voltage of 14.8 V in bulk. The daily regimen, when in storage, keeps the float voltage above 13.6. I have added water twice in the last year and the wet cells have an SG of close to 1.30. It just can't get much better than that.
