We leave our batteries in our RV over the winter, our garage is not insulated so temps are not much warmer than exterior temps. Since we have our RVs stored at our residence they are plugged in 24/7 in most cases. No need for us to purchase a separate trickle charger, our multiphase converter and inverter charger with temp compensation do a great job of keeping batteries properly charged no matter the time of year.
Same here.
Most converters (and inverter-chargers) built in the last 20 years do an excellent job of maintaining the batteries.
