Choosing the correct battery type for a 2010 Lexus IS 250 C is essential to maintain reliability and protect sensitive systems. The vehicle requires a 12-volt automotive battery; many examples of this model originally use maintenance-free lead-acid batteries, while some configurations or replacements may call for an AGM battery.
