6. Operating Instructions
The Interstate MTP-35 is a standard automotive starting battery. Once properly installed, it will provide power to start your vehicle and operate its electrical systems. The battery is designed to be recharged by your vehicle's alternator during operation.
Charging:
If the battery becomes discharged, it can be recharged using a compatible 12V automotive battery charger. Follow the charger manufacturer's instructions carefully. Ensure proper ventilation during charging.
7. Maintenance
While the MTP-35 is a maintenance-free flooded battery, regular checks can help extend its lifespan and ensure optimal performance.
Maintenance Tips:
- Keep Clean: Periodically clean the top of the battery and terminals with a damp cloth to remove dirt and grime. Ensure terminals are free of corrosion.
- Check Connections: Ensure battery cables are always tight and secure. Loose connections can lead to poor performance and damage.
- Regular Use or Charging: If your vehicle is not used frequently, consider using a trickle charger or battery maintainer to keep the battery fully charged. This prevents deep discharge, which can shorten battery life.
- Avoid Deep Discharge: Do not allow the battery to completely discharge. This can significantly reduce its lifespan.
8. Troubleshooting
Here are some common issues and potential solutions:
- Slow Cranking: This often indicates a low battery charge. Check the battery voltage and recharge if necessary. Also, inspect terminals for corrosion or loose connections.
- No Start/Clicking Sound: A completely dead battery or very low charge. Attempt to jump-start the vehicle or recharge the battery. Check all connections.
- Corrosion on Terminals: Clean terminals with a wire brush and a mixture of baking soda and water. Rinse with clean water and dry thoroughly. Apply anti-corrosion grease.
- Battery Light on Dashboard: This usually indicates an issue with the vehicle's charging system (alternator) or the battery itself. Have your vehicle's electrical system inspected by a qualified mechanic.
