There is a lot of "Talk" about DC to DC chargers and "Do i really need it" questions about this subject.

Fact is, you will 100% benefit from DC to DC charging in any dual battery setup. The DC to DC chargers switch off when the batteries are full and goes into float charge. So you can never overcharge your expensive batteries. The other reason why you are better off with a DC-DC charger is it will charge your battery to 100% of its claimed capacity. Alternators wont do this.

However, many newer 4wd's/cars run what we call a "smart alternator" or "variable alternator" what this means is your 4wd/car monitors your electrical usage and shuts down the alternators output. With these 4wds/cars you have no choice but to use DC to DC chargers to keep those voltages high enough for aux batteries to charge.
