Setup and Initial Charging

Upon receiving your ML35-12 battery, it is recommended to perform an initial charge to ensure optimal performance. Use a compatible 12V battery charger designed for SLA/AGM batteries. Ensure the charger's voltage regulation is set between 13.6V and 13.8V for floating use, or 14.5V and 14.9V for cycle use, with an initial current less than 10.5A.

Connection Guidelines:

Connect the positive (+) terminal of the battery to the positive lead of your application or charger, and the negative (-) terminal to the negative lead. Ensure all connections are secure to prevent arcing or poor performance. Do not short the battery terminals.

Operating Your Battery

The ML35-12 is a deep cycle battery, suitable for applications requiring regular deep discharge and recharge cycles. Avoid over-discharging the battery beyond its recommended limits to prolong its lifespan. Monitor the battery voltage during operation to prevent excessive discharge.

Environmental Considerations:

The battery is designed to operate across a wide range of temperatures. However, extreme temperatures can affect performance and lifespan. Refer to the performance characteristic graphs in the 'Product Visuals' section for detailed information on temperature effects on capacity and float life.

Maintenance and Storage

This battery is a Sealed Lead Acid (SLA) type, which means it is maintenance-free and does not require water additions. Its Absorbent Glass Mat (AGM) technology ensures a spill-proof design, allowing for mounting in various positions without leakage concerns.

Long-Term Storage:

For long-term storage, ensure the battery is fully charged before storing. Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures. Periodically check the battery voltage and recharge if it drops below 12.5V to prevent sulfation and maintain capacity.

Troubleshooting Common Issues

• Battery Not Holding Charge: Verify the charger is functioning correctly and is compatible with SLA batteries. Check for loose or corroded terminal connections.
• Insufficient Power Output: Ensure the battery is fully charged. Review the application's power requirements to confirm the battery's capacity (35AH) is adequate.
• Physical Damage or Leakage: If the battery appears physically damaged or is leaking, discontinue use immediately and follow local regulations for disposal. Do not attempt to repair a damaged battery.
