It is only rated for charging 1.2–32 Ah batteries.
The cases on the CTEKs 4.3 does get warm but not "too hot to the touch". I would suggest leaving any charger out in open with plenty of air circulation. Electronics don't like excessive heat anyway so better air circulation is always better.

With a Kill-a-watt, I measured the idle current of my 0.8 amp CTEK when the battery was fully charged. It was 0.05 amps, that's 6 watts at 120V.
Do you have a Kill-a-watt? Curious what the idle current is on your bigger 4.3 amp unit.
