ZAF Energy Systems Inc., Columbia Falls, Mont., introduced a new rechargeable Nickel Zinc (NiZn) battery for commercial trucks, buses and defense vehicles.

During testing, four ZAF NiZn batteries are said to take on the same workload as the eight lead acid batteries that are typically used in 18-wheel commercial long haul trucks. This system also fully supports 10-hour cycles for mandatory rest periods, regenerative braking, removes the need for engine-driven accessories and eliminates the possibility of alternator failures.
