Instructions for Replacing the Battery

Model: Mazda 3 BK, MK 1 - Years 2003-2009
Part: Battery

The battery is located in the engine bay, just behind the air filter housing. Before proceeding with the replacement, ensure you have the correct model of battery to install: amperage, position, and size of the terminals. Once you have selected the new battery, proceed to remove the old one: remove the upper mounting bracket, disconnect the terminals, and extract it from its location. Then, place the new battery, connect and tighten the terminal clamps, and secure it by tightening the nuts of the respective bracket. Optionally, apply grease to the terminals to prevent oxidation.
