I keep them on my engine crank batteries as well as the house batteries on the houseboat. There is a regular onboard charger but the trickle chargers are less likely to cause the batteries to boil dry, in my opinion. Also, when the house batteries are dead, so is the water pump and the head. Momma isn't happy when that happens!
