3.1. What's in the Box

• Two (2) Technical Precision Replacement Batteries (12 Volts each)

4. Setup and Installation

Follow these steps for safe and correct installation of the replacement battery pack:

1. Preparation: Ensure the NILFISK-Advance SC500 equipment is turned off and disconnected from any power source. Wear safety glasses and gloves.
2. Remove Old Batteries: Carefully disconnect the cables from the old batteries, noting the positive (+) and negative (-) connections. Typically, disconnect the negative terminal first. Remove the old batteries from the equipment.
3. Install New Batteries: Place the two new Technical Precision 12-volt batteries into the battery compartment of the NILFISK-Advance SC500. Ensure they are securely positioned.
4. Connect in Series: To achieve 24 volts, connect the positive terminal of one 12-volt battery to the negative terminal of the other 12-volt battery using a suitable jumper cable (not included, typically part of the equipment's wiring harness).
5. Connect to Equipment: Connect the remaining positive terminal of one battery to the positive terminal of the NILFISK-Advance SC500 equipment. Connect the remaining negative terminal of the other battery to the negative terminal of the equipment. Always connect the positive terminal last.
6. Secure Connections: Ensure all cable connections are tight and secure to prevent arcing or poor performance.
7. Initial Charge: After installation, it is recommended to fully charge the new battery pack before initial use. Refer to the 'Operating' section for charging instructions.

Important: Incorrect wiring can damage the batteries and equipment, and pose a safety hazard. If you are unsure about the installation process, consult a qualified technician.

5. Operating Instructions

5.1. Charging the Battery Pack

For optimal performance and longevity, follow these charging guidelines:

• Use a charger specifically designed for 24-volt NiMH battery packs. Using an incompatible charger can damage the batteries.
• Connect the charger to the NILFISK-Advance SC500 equipment's charging port.
• Ensure the charging area is well-ventilated.
• Allow the battery pack to charge completely. Refer to your equipment's manual for typical charging times.
• Avoid overcharging, as this can reduce battery life. Most modern chargers have automatic shut-off features.

5.2. Discharging and Use

Operate your equipment as usual. It is generally recommended to avoid deep discharges (running the batteries completely flat) frequently, as this can shorten the lifespan of NiMH batteries. Recharge the battery pack when the equipment indicates low power.

6. Maintenance

Proper maintenance will help extend the life and performance of your battery pack:

• Regular Cleaning: Keep the battery terminals and surrounding area clean and free of dirt, dust, and corrosion. Use a dry cloth or a brush. If corrosion is present, clean with a mixture of baking soda and water, then rinse with clean water and dry thoroughly.
• Terminal Inspection: Periodically check all cable connections to ensure they are tight and free from damage. Loose connections can lead to power loss and heat buildup.
• Storage: If the equipment will not be used for an extended period, store the battery pack in a cool, dry place. NiMH batteries should ideally be stored with a partial charge (around 40-50% capacity) to prevent deep discharge and maintain cell health. Avoid storing in extreme temperatures.
• Recharge During Storage: For long-term storage, recharge the battery pack every 3-6 months to prevent self-discharge below critical levels.
