1. Regularly check the reliability of the Oil Electric Hybrid Sedan terminals and connectors. To prevent oxidation of the connectors, apply a protective agent such as petroleum jelly.
2. Ensure the vent holes on the Electric Car battery cover are clear. During charging, the battery forms numerous air bubbles. If the vents are blocked, preventing air escape, the pressure can increase to a certain level, causing the battery casing to crack.
3. Do not use a direct spark test (short circuit test) to check the battery's capacity, as this will damage the battery.
4. Check the electrolyte level inside the battery. If the electrolyte level is too low, add distilled water or special lead-acid battery electrolyte. Never use purified drinking water as a substitute.
5. When using the Electric Car, gently press the accelerator pedal; otherwise, a sudden large current discharge can damage the battery.
6. After short-distance use, it is recommended to fully charge the battery immediately to keep it at a saturated state and extend its lifespan.
