4. Installation and Setup

Before installation, ensure the battery is fully charged. Always wear appropriate personal protective equipment, including safety glasses and gloves.

Installation Steps:

1. Verify Compatibility: Confirm that the DCM0035 battery is the correct replacement for your device. Refer to your device's manual for specific battery requirements.
2. Prepare the Area: Ensure the installation area is clean, dry, and well-ventilated.
3. Disconnect Old Battery: Always disconnect the negative (-) terminal first, followed by the positive (+) terminal of the old battery.
4. Position New Battery: Carefully place the DCM0035 battery into the battery compartment. Its dimensions are 7.68" (L) x 5.16" (W) x 6.42" (H).
5. Connect Terminals: Connect the positive (+) terminal first, then the negative (-) terminal. Ensure connections are secure but do not overtighten. The DCM0035 uses insert terminals with bolts.
6. Secure Battery: Use any existing straps or brackets to secure the battery firmly in place to prevent movement during operation.

5. Operation

The DCM0035 is a deep cycle battery designed for continuous discharge and recharge cycles. For optimal performance and longevity, adhere to the following operational guidelines:

• Initial Charge: Although batteries often arrive partially charged, it is recommended to fully charge the battery before its first use.
• Daily Recharging: For applications like electric wheelchairs and scooters, it is recommended to recharge the battery daily, especially after significant use, to maximize its lifespan.
• Charging Voltage:
  • Floating Use: 13.6 - 13.8 VDC
  • Cycle Use: 14.6 - 14.8 VDC
• Avoid Deep Discharge: While designed for deep cycles, consistently discharging the battery to extremely low levels can reduce its overall lifespan. Recharge promptly when the device indicates low power.

6. Maintenance and Care

The DCM0035 is a maintenance-free battery, meaning it does not require water additions or electrolyte checks. However, proper care ensures its longevity:

• Keep Clean: Periodically clean the battery terminals and case to prevent corrosion and ensure good electrical contact. Use a damp cloth and avoid harsh chemicals.
• Storage: If storing the battery for an extended period, ensure it is fully charged and stored in a cool, dry place. Recharge every 3-6 months to prevent self-discharge. The storage temperature should not exceed 60°C (140°F).
• Recycling: When the battery reaches the end of its useful life, it must be recycled. Interstate Batteries recycles more batteries than they sell. Please return your used battery to an Interstate All Battery Center near you.
