Safety Information

Always observe the following safety precautions when handling batteries and battery acid:

• Wear appropriate personal protective equipment, including safety glasses and acid-resistant gloves.
• Work in a well-ventilated area.
• Keep sparks, flames, and smoking materials away from the battery. Batteries produce explosive gases.
• Avoid contact with battery acid. If contact occurs, flush immediately with water and seek medical attention.
• Keep out of reach of children.

Setup: Adding Electrolyte and Initial Charge

This MTD 925-1707D battery is shipped DRY and contains NO acid. You must purchase battery acid (electrolyte) separately and add it before use. The required volume of acid is approximately 42 oz (two 21 oz containers).

Materials Required:

• Battery acid (electrolyte) - Sold Separately
• Safety glasses
• Acid-resistant gloves
• Battery charger (compatible with lead-acid batteries)

Procedure:

1. Prepare the Area: Work in a well-ventilated area, preferably outdoors, on a level surface. Place the battery on a protective mat or old newspapers.
2. Remove Vent Caps: Carefully remove the vent caps or strip from the top of the battery. Keep them in a safe place.
3. Add Electrolyte: Slowly and carefully pour the battery acid into each cell until the fluid level reaches the "UPPER" or "MAX" fill line indicated on the battery casing. Avoid overfilling.
4. Allow to Settle: After filling, allow the battery to sit for 30-60 minutes. This allows the acid to soak into the plates and any air bubbles to escape. Check the fluid levels again and add more acid if necessary to reach the fill line.
5. Initial Charge: Connect the battery to a compatible battery charger. Charge the battery according to the charger manufacturer's instructions until it is fully charged. A typical initial charge may take several hours.
6. Reinstall Vent Caps: Once charging is complete and the battery has cooled, securely reinstall the vent caps or strip.

Installation

Before installing the new battery, ensure the equipment's ignition is off and the parking brake is engaged. Refer to your equipment's owner's manual for specific battery compartment location and access.

1. Remove Old Battery (if applicable): Disconnect the negative (-) terminal first, then the positive (+) terminal. Carefully remove the old battery.
2. Clean Battery Tray and Cables: Clean any corrosion from the battery tray and cable terminals using a wire brush and a baking soda/water solution. Rinse with clean water and dry thoroughly.
3. Position New Battery: Place the new MTD 925-1707D battery securely in the battery tray.
4. Connect Terminals: Connect the positive (+) cable to the positive (+) battery terminal first. Tighten the connection. Then, connect the negative (-) cable to the negative (-) battery terminal and tighten. Ensure all connections are secure.
5. Secure Battery: If your equipment has a battery hold-down strap or clamp, secure the battery firmly to prevent movement during operation.

Operation

Once the battery is properly installed and fully charged, your equipment is ready for use. Refer to your equipment's owner's manual for specific starting procedures.

• Ensure all safety interlocks are engaged before attempting to start the engine.
• Turn the ignition key or press the start button as directed by your equipment's manual.

Maintenance

Proper maintenance extends battery life and ensures reliable performance.

• Check Electrolyte Levels: Periodically check the electrolyte levels (every 1-3 months, or more frequently in hot climates). If levels are low, add distilled water only to the "UPPER" or "MAX" fill line. Do not add battery acid after the initial fill.
• Clean Terminals: Keep battery terminals clean and free of corrosion. Use a wire brush and a baking soda/water solution if corrosion is present. Apply a thin layer of dielectric grease to prevent future corrosion.
• Keep Charged: For optimal performance, keep the battery fully charged, especially during periods of non-use. A trickle charger or battery maintainer is recommended for long-term storage.
• Storage: If storing the equipment or battery for an extended period (e.g., over winter), remove the battery, clean it, fully charge it, and store it in a cool, dry place. Recharge periodically during storage.
