5. Operating Instructions
Your SigmasTek STX7A-BS battery is factory-charged and ready for immediate use. For optimal performance and longevity, consider the following:
- Initial Start-up: After installation, the ATV should start normally. If not, recheck connections.
- Charging: While the battery comes pre-charged, if the ATV is stored for extended periods or experiences slow cranking, a maintenance charger designed for AGM batteries can be used. Follow the charger manufacturer's instructions.
- Avoid Deep Discharge: Repeated deep discharge can shorten battery life. Ensure the ATV's charging system is functioning correctly to maintain battery charge during operation.
6. Maintenance
The SigmasTek STX7A-BS is a maintenance-free AGM battery, but periodic checks can help ensure its long life:
- Terminal Inspection: Periodically check battery terminals for cleanliness and tightness. Clean any corrosion with a wire brush and a baking soda/water solution.
- Battery Case: Keep the battery case clean and dry.
- Voltage Check: If the ATV is stored for an extended period, check the battery voltage every few months. A fully charged 12V battery should read approximately 12.6V or higher.
- Recharging During Storage: If the voltage drops below 12.4V during storage, recharge the battery using a suitable AGM-compatible charger to prevent sulfation and maintain capacity.
7. Troubleshooting
If you encounter issues with your battery, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine cranks slowly or not at all | Low battery charge, loose or corroded terminals | Recharge battery, clean and tighten terminals. Check ATV charging system. |
| Battery not holding a charge | Faulty charging system, parasitic drain, aged battery | Inspect ATV charging system (alternator/regulator). Check for electrical components drawing power when off. If battery is old, consider replacement. |
| Corrosion on terminals | Normal chemical reaction, loose connections | Clean terminals with a wire brush and baking soda/water solution. Ensure connections are tight. |
If problems persist after attempting these solutions, consult a qualified technician or contact SigmasTek customer support.
