Currently working through a project for my Duster which will require the use of a second deep cycle battery.
The battery I've selected is a small 7.5Ah unit that has a max charging current of just 10A.
I'm trying to work out if I need a B2B charger or if I could get away with a simple relay that comes on with the ignition or a voltage sensitive relay.
So are batteries designed in such a way that if 12-16v is applied to the battery (assuming it is empty), it would only accept the maximum charge rate? I.e. the resistance across the battery low enough when empty that at it's rated voltage, only the maximum current could flow?
I feel like this is an embarrassing question being an electrician by trade, but little experience with batteries.
