Why Does Infiniti Have Two Batteries?
2 Answers
Infiniti has two batteries for the following reason: the two batteries are divided into a large one and a small one. The large battery powers the vehicle's electrical equipment and starting system, while the small battery is used for emergency gear unlocking when the large battery runs out of power. Below is some relevant information about Infiniti vehicles: 1. Powertrain: Equipped with a 5.6-liter V8 engine, delivering a maximum power of 298 kW (400 horsepower) and a maximum torque of 560 N·m, paired with a 7-speed automatic transmission and featuring a full-time four-wheel drive system. 2. Interior: The Infiniti QX80 comes standard with intelligent cruise control, three rows of leather seats, front/second-row seat heating, and other configurations.
I noticed that Infiniti vehicles are equipped with two batteries, which makes a lot of sense. The main battery is specifically responsible for starting the engine, providing the initial power to the car. The auxiliary battery, on the other hand, handles various electronic devices in the vehicle, such as the start-stop system. Since many Infiniti models feature automatic start-stop functionality, the engine frequently stops and starts during traffic lights or congestion. If only a single battery were used, the power could easily be depleted, leading to startup failures. The dual-battery system shares the load: the main battery focuses solely on starting, while the auxiliary battery keeps the air conditioning or audio system running without interruption. I also found this particularly useful in winter when battery performance declines in low temperatures—the dual system ensures the car starts immediately without stalling on the roadside. Additionally, the auxiliary battery helps save fuel, reduces strain on the main battery, and extends its overall lifespan. The design reflects a strong emphasis on driving comfort and reliability. As an owner, I think this setup is worthwhile, but during maintenance, it's essential to check the condition of both batteries to avoid one failing while the other keeps running.
