I have one like this and its good.
When you connect a dull battery the needle will shoot up the scale to show how many Amps the battery is taking out of the charger, its not a sign of whats IN the battery, when the needle works down to 0 Amps on the scale then thats the battery as charged as its going to be.
Roughly speaking a leisure battery or a large one like you have is going to take a couple of days to fully charge, itl draw alot out the charger as soon as its connected and slowly draw less as it becomes more charged.
Car batteries and leisure batteries are wildly different in their technology, a car battery is designed to give alot of power quickly then be charged rapidly, a leisure battery is designed to give a steady power for a longer time then be charged slowly.
It used to be the case that car batteries were 200 cycle and leisure batteries were 400 cycle, a cycle being fully charged to flat then back to fully charged again.
I doubt its the same now.
