The S34B20R Battery in the Toyota Prius
A Prius has a 12-volt auxiliary battery for vehicle electronics and a separate high-voltage traction battery for the hybrid drive system. Some fitment listings identify the S34B20R as a replacement for selected Prius applications, but that does not establish it as the correct auxiliary battery for every Prius. Verify the exact year, generation, trim, and market using the VIN, owner's manual, or current vehicle-specific catalog.

What does a Group 34 battery mean
BCI Group 34 is a North American automotive fitment category with specified dimensions and terminal layout. It is not the same designation as “S34” in the GS Yuasa HJ-S34B20R product name: Yuasa lists that battery as B20 JIS. Do not infer that a vehicle needs Group 34 from those shared characters. Verify the exact year, market, trim, and OEM battery specification before buying.
