Newer 4x4s are equipped with batteries that meet their electrical needs, and those needs are much greater than those of their predecessors. Fifteen years ago, some manufacturers would have told you that most vehicles on the road in 2020 would be running 48V systems—due to the increased electrical demands of newer cars for hybrid systems, safety features, and increased electrical needs in-cab. But the great majority of newer vehicles are still using 12V- (closer to 14V-) based DC electrical systems with more powerful alternators and improved lead-acid batteries that have higher cranking amperages and longer reserve capacities.
