The 2012 Toyota Prius uses a 12-volt auxiliary battery to power control modules, electronics, and key-on functions; the high-voltage hybrid pack is separate and not part of this service. Many Prius models use an AGM-style auxiliary battery, and placement is commonly in the rear cargo area rather than the engine bay—this design helps with packaging and reduces exposure to heat. If your car still has its original-style unit or the age is unknown, a health check is wise before peak seasons.
