OE 37180-N9500 — Sensor ASSY Battery for Hyundai

Treat it as a wear item: inspect every 20,000-30,000 km and replace at the first sign of leakage, noise or performance loss. Real service life swings widely with climate, road surface and duty cycle, so mileage on its own is a weak indicator.

Match three things: the code on the part you are removing, the build-year range in the Applications table, and the mounting points visible in the reference photo. If all three line up, 37180-N9500 is a confirmed fit. Send your VIN and our export desk will double-check the ambiguous cases.

Start from the code cast or printed on the part you are removing — that is the authoritative source. If it is illegible, use the Applications table on the closest electrical & sensors reference and narrow by build year. Send photos and we will cross-check the number for you.

Four variables explain most of the spread: material grade, whether the goods are new production or clearance stock, packing format, and whether the quote is ex-works or landed. Ask for the material certificate alongside the price — that is what makes a comparison like-for-like.

A supersession happens when the maker revises a sensor assy battery and issues a new tail number. The revision normally changes a small physical detail rather than the fit. Where we know a supersession chain for 37180-N9500 we list the current reference; ask our desk for written confirmation before a large order.

OEM means the part was produced for the vehicle maker's assembly line; aftermarket means it is made independently to the same engineering drawing. For a sensor assy battery the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.
