6. Operating Instructions
This battery is designed for starting motorcycles and powersports vehicles. To maximize its lifespan and ensure reliable performance:
- Ensure the battery is fully charged before initial use.
- Avoid deep discharges, which can significantly reduce battery life.
- If the vehicle is not used for extended periods, consider using a compatible trickle charger to maintain the battery's charge level.
7. Maintenance
The SigmasTek STX7A-BS is an AGM maintenance-free battery and does not require water additions. However, regular checks and proper storage are essential for optimal performance.
Cleaning
Keep the battery terminals clean and free of corrosion. If corrosion is present, use a wire brush and a mixture of baking soda and water to clean the terminals. Rinse with clean water and dry thoroughly before reconnecting.
Charging
If the battery voltage drops below 12.4V, recharge it using a compatible motorcycle battery charger. Do not overcharge, as this can damage the battery. The recommended charge current for this battery is 0.70 Amps.
Storage
For optimal lifespan, store the battery in a cool, dry place. SigmasTek ST series batteries can be stored for up to 6 months at 25°C (77°F) before a freshening charge is recommended. Higher storage temperatures will shorten this interval due to increased self-discharge rates. Refer to the discharge characteristics chart for more details on self-discharge behavior.
