Operating
Once installed, the Interstate MTP-86 battery provides the necessary power to start your vehicle and operate its electrical systems. Ensure your vehicle's charging system is functioning correctly to maintain the battery's charge. Avoid excessive discharge, as this can shorten battery life.
Maintenance
Regular maintenance helps extend the life and performance of your MTP-86 battery:
- Terminal Cleaning: Periodically inspect battery terminals for corrosion. Clean any corrosion with a wire brush and a baking soda/water solution. Rinse and dry.
- Fluid Level Check (Flooded Batteries): For flooded batteries like the MTP-86, check the electrolyte levels regularly. If low, add distilled water to the appropriate level. Do not overfill.
