Car Battery Iriz (55B24R / NS60 class)

OEM number not published: Proton does not sell a battery under its own part number. The battery is fitted by the dealer from a vendor, so buy by application instead, which for the Iriz means the B24 / NS60 class (12V, 45 to 50Ah) with the terminal layout matching the factory battery. The 55B24R in the part number field is the JIS size code sellers use for this fitment, not a Proton part number.

A few sellers still list an NS40ZL for certain build years. Treat the B24 class as the safe stand-in because it shares the tray and terminal pattern, and confirm terminal orientation (R versus L) against the battery in your car before ordering, since a reversed unit is a common return.

Expect 18 to 24 months of life in Malaysian heat. Indicative range RM210 to RM260 depending on brand and Ah rating.
