most of us have intverter chargers that are "smart".
xantrex, outback are a couple of great ones. i have the freedom 458 by xantrex that is a 2kw inverter. if i was to replace it, i would get a pure sine wave versus the modified sine wave that i have now.
of course you might have to do some rewiring to install if you dont have an inverter charger now.
the original battery charger or "boiler" that came in mine and i bet is the same one in yours is still installed in the bay but unplugged.
