Before you buy
Match the group size, terminal layout and cold-cranking amps in your owner's manual. If your car came with an AGM battery or has start-stop, replace it with the same type. Check the date code on the case.
Confirm the part fits your exact 2021 Mazda Mazda3 by checking your VIN, engine size and trim with the seller. The Mazda3 was sold with different options across the 2021 model year, and a part that fits one build may not fit another.
