I haven't used one because I simply never had to need to with an OPTIMA battery. But it's quite simple for you to build one yourself. if you scan the internet, you will easily find the electrical diagram for one, give it to an electric workshop he will build it, very cheap.
Dual battery is used for cars that have powerful light bars, reak fridge, powerful sound system (street cars) or used as a backup system if you're going on a long 1,000 Km safari in the desert or jungle.
Other than that it's a waste of money in my opinion.
