First Use

1. Complete Initial Inspection- Unpack your Milwaukee 18V M18 REDLITHIUM battery and visually inspect it to ensure no damage has occurred during shipping. Check that the electrical contacts are clean and free of dust or debris that could affect the connection with yourM18 tools.
2. Initial Full Charge- Before first use, fully charge the battery for approximately 2 hours with a compatible Milwaukee M18 charger. This initial charge optimizes the maximum capacity and fully activates the REDLINK Intelligence system to ensure optimal performance and extended life of your ultra-high capacity REDLITHIUM FORGE battery.
3. Functionality Test- Insert the battery into an M18-compatible tool until you hear a locking click. Press the LED indicator button to check the charge level and briefly test the tool to confirm that the FORGE REDLITHIUM battery is delivering the consistent power characteristic of this advanced technology.
4. Familiarization with AutonomyNote the exceptional performance of your 8.0 Ah battery (extended runtime, consistent power) compared to lower-capacity batteries. The REDLINK system will maintain this optimal performance throughout the battery's extended lifespan.

Regular Maintenance

Monthly Checks

• Inspect the electrical contacts and clean them gently with a dry cloth if necessary.
• Check the overall condition of the reinforced casing for cracks or damage.
• Test the LED indicator to ensure it is working correctly.
• Make sure the ventilation openings are not blocked by debris

Load Management

• Recharge the battery before it is completely discharged to optimize its lifespan.
• Use only chargersMilwaukee certified compatible M18
• Take advantage of the 90-120 minute fast charge to maintain maximum productivity
• Avoid leaving the battery completely discharged for extended periods.

Performance Monitoring

• Note any significant decrease in exceptional characteristic autonomy
• Monitor the temperature during intensive use with high-power tools
• Check that the REDLINK system is functioning correctly without excessive overheating
• Immediately replace any battery that shows signs of swelling, leakage, or abnormal behavior.

Cleaning and Maintenance

Clean the exterior of the Milwaukee REDLITHIUM FORGE battery with a slightly damp cloth after use on dusty jobsites, taking care to avoid getting water inside the electrical connectors. Never use solvents, gasoline, or harsh chemicals that could damage the reinforced casing or compromise the REDLINK Intelligence system.

For electrical contacts, use a pencil eraser or a dry cloth to gently remove any oxidation or metallic residue buildup. Ensure the contacts are completely dry before inserting the battery into a tool or charger to prevent short circuits that could damage the sophisticated REDLINK system.

Regularly inspect the ventilation openings and use low-pressure compressed air to remove any accumulated wood, metal, or concrete dust. Never attempt to open the REDLITHIUM FORGE battery casing, as this will immediately void the 3-year warranty and irreparably damage the advanced REDLINK electronic system.

Precautions for Use

Never expose the Milwaukee 18V M18 REDLITHIUM FORGE battery to temperatures above 50°C, as this could damage the lithium-ion cells and compromise the REDLINK system. Although this battery is cold-resistant down to -18°C, avoid extreme thermal shock by allowing the battery to acclimatize gradually when moving between very different temperatures.

Avoid violent shocks, drops, and impacts that could damage the internal structure or the REDLINK Intelligence system. Although the reinforced casing is robust, the 1.2 kg weight can cause damage if dropped from a significant height.

Never use a battery that shows signs of physical damage, cracks, bulges, or leaks. Due to the high capacity of 8.0 Ah, a damaged battery presents increased risks. If you notice any of these problems, stop use immediately and contact Polar Industrial Equipment for advice on safe disposal.

Keep the battery away from flammable materials and never charge it near heat sources or in confined spaces without adequate ventilation. Never immerse the battery in water or any other liquid.

Storage Tips

Store your Milwaukee 18V M18 REDLITHIUM FORGE battery in a cool, dry place, ideally at room temperature between 15°C and 25°C, away from direct sunlight and excessive humidity. The REDLINK system is designed to protect the battery even during storage, but optimal conditions will further extend its lifespan.

For extended storage of more than one month, maintain the battery at a charge level of approximately 40 to 60% (around 50%) rather than fully charged or completely discharged. This practice optimizes the preservation of the lithium-ion cells and maintains maximum capacity over the long term.

Use the original packaging or a protective case to prevent accidental contact between the electrical terminals and metal objects. Ultra-high capacity 8.0 Ah batteries can deliver a very high current in the event of a short circuit.

Check and recharge the battery at least every 3 months, even if it is not in use. The REDLINK system minimizes natural self-discharge, but periodic recharging maintains optimal electrochemical health and ensures it is ready to use immediately with full REDLITHIUM performance.

8. WARRANTY

Polar Industrial Equipment offers a 30-day money-back guarantee on this product. If you are not completely satisfied, you can return the battery in its original packaging and in new condition for a full refund.
