When analyzing the battery requirements for the Nissan Murano across its generations, it becomes clear that the changes in battery specifications reflect both the evolving technology and the consistent demands of this model. The provided table compares two generations: the first-generation Murano (I, Z50) and the second-generation Murano (II, Z51). Although the table lists the number of engines, this value should be interpreted as the prevalence or importance of the requirements for each generation rather than the actual number of engine variants.
Starting with the first generation, the Nissan Murano I (Z50) is characterized by relatively standard battery requirements for its class and the era in which it was produced. The table indicates that the Z50 does not feature a Start-Stop system, a technology that automatically shuts down and restarts the engine to reduce idling time, thus saving fuel and reducing emissions. As a result, the battery required for this generation is of the standard type, without the need for enhanced durability or deep-cycle capabilities that Start-Stop systems demand. The minimal capacity for the battery starts at 60 Ah (ampere-hours) and goes up to a maximum of 65 Ah, which is typical for mid-size SUVs with conventional electrical systems. The starting current required ranges from 390 A to 580 A, ensuring sufficient power for cold starts and the basic electrical demands of the vehicle.
Moving to the second generation, the Nissan Murano II (Z51), we observe that, despite technological advancements and a possible increase in onboard electrical systems, the battery requirements remain very similar to those of the first generation. The Z51 also does not employ a Start-Stop system, indicating that Nissan maintained a focus on conventional battery technology for this generation as well. The battery type required is still standard, with the minimum and maximum capacities unchanged at 60 Ah and 65 Ah, respectively. The starting current range also remains at 390 A to 580 A. This consistency suggests that the core electrical architecture and engine requirements did not undergo significant changes between these generations, at least in terms of battery load and starting demand.
What stands out in this comparison is the stability of the battery requirements over time. While many manufacturers have shifted toward advanced battery systems—such as AGM or EFB types—particularly in vehicles equipped with Start-Stop technology, the Murano has maintained a preference for standard batteries. This could be due to a variety of reasons, including design simplicity, reliability, cost-effectiveness, or the absence of fuel-saving features that would necessitate a more robust battery. The range of battery capacity (60–65 Ah) and starting current (390–580 A) is broad enough to accommodate various climates and operating conditions, but it does not reflect a significant technological leap between the two generations.
Another important aspect is that both generations specify a rather broad range for starting current. This range allows for flexibility in battery selection, accommodating batteries from different manufacturers and markets. It also provides a margin for users in colder climates, where higher starting current is beneficial for reliable engine ignition in low temperatures. The absence of Start-Stop technology across both generations simplifies battery selection and maintenance, as standard batteries are generally less expensive and more widely available than their enhanced counterparts.
In summary, the battery requirements for the Nissan Murano have remained largely consistent across the first and second generations, both in terms of capacity and starting current. The lack of Start-Stop systems means that standard batteries are sufficient, and there is no need for more advanced types. This stability simplifies maintenance and replacement for Murano owners, as there is little variation to consider when choosing a battery.
