Adding distilled water or a special replenishing fluid when the electrolyte is low; 3. Frequently checking whether the small holes on the battery cover are ventilated during daily driving; 4. Checking for signs of oxidation on the positive and negative terminals of the battery; 5. Inspecting all parts of the circuit for signs of aging or short circuits; 6. Turning off electrical devices when leaving the car.
