When the charge cycle is complete does the charger serve as a trickle charger? I have seen some 48 volt trickles and was wondering if that would be a good idea in the winter months when it's parked for several weeks. thanks
Older ferro resonant chargers shut off at the end of the cycle and generally speaking that's the end.
Some of the newer ones have a constantly maintained float voltage with a periodic maintenance cycle.
Start with some info on your cart. What is it, year etc. Is the charger the original and what does it say on the face plate?
Golf carts do not use trickle chargers, they may have a holding float voltage, depends on the charger.
