My plans are to add a more modern converter in the future and keep the old one for backup.

Those old converters were heavy and solid. My heat sinks are 8" x 8" plates - one on each side. They had massive transformers with huge diodes on the heat sinks. Mine, built in 1972-3, will probably last another 50 years, but it just doesn't have the smarts to treat a battery well. They had lousy voltage regulation and no concept of stages (bulk, absorption, float, equalization, etc.).
I'm considering pulling out the transformer to run my outdoor 12V lighting system. I thought about keeping it, adding some linear voltage control and smart circuitry for battery charging, but the cost/time wasn't worth it.

The relay switched the converter in and out isolating the battery when the converter took over duty of powering up the 12 volt system.

What OBC are you guys using that puts out over 15 volts?
