My multi-stage battery charger died (OK, well I dropped it and broke it) so I ordered a new CTEK charger. Only after it arrived did it occur to me that I could use this in the camper. The converter in my camper is useless so I don't ever use it (it produces something like 17v of very noisy DC) so I am always relying on the solar to charge the batteries through a CTEK DC-to-DC "max power point tracker" charger.
so this new charger comes with an easy disconnect so you can permanently wire a connector and temperature gauge onto your camper battery and alternate between plugging the charger into that, or unplugging it, plugging in to the crocodile clips instead and charging vehicles. So what was meant as a simple replacement is now also a gift to the camper.
