Battery not charging

Check all cable connections for tightness and corrosion. Verify that the charging source (e.g., alternator, charger) is functioning correctly and outputting the appropriate voltage.

Reduced performance or capacity

Ensure the battery has been fully charged. Check for any parasitic drains on the electrical system. If the battery is old, it may be nearing the end of its service life.

Corrosion on terminals

Disconnect the battery, clean the terminals with a wire brush and a baking soda/water paste. Rinse and dry thoroughly before reconnecting. Apply a terminal protector spray.
