Nissan Dayz Hybrid Battery

This Nissan Dayz hybrid battery is a high-voltage energy storage unit used in the vehicle’s hybrid system. It works by storing electrical energy generated during driving and assisting the engine during acceleration and low-load conditions.

It also supports the start-stop (eco idle) system, helping reduce fuel consumption by shutting off and restarting the engine automatically in traffic conditions. The battery plays a key role in improving overall fuel efficiency and smoother driving performance.

In Nissan Dayz hybrid models (S-Hybrid system), the battery is a compact assist-type unit rather than a full electric drivetrain battery, designed mainly to support the petrol engine rather than run the vehicle on electricity alone.

This unit is commonly available as a used imported part and is preferred for its original system compatibility, proper hybrid integration, and reliable performance compared to aftermarket alternatives.
