First Use

1. Initial Inspection- Unpack your DeWalt 20V MAX POWERSTACK 3.5 Ah 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 your tools.
2. Initial Full Charge- Before first use, fully charge the battery for approximately 55 minutes with a compatible DeWalt 20V MAX charger. This initial charge optimizes capacity and fully activates the POWERSTACK electronic management system to ensure optimal performance.
3. Functionality Test- Insert the battery into a compatible 20V MAX tool until you hear the locking click. Briefly test the tool to experience the significant improvement in balance and maneuverability thanks to the low profile characteristic of POWERSTACK technology.
4. Familiarization with the Format- Note the remarkably low profile and superior balance of your tool equipped with the POWERSTACK battery compared to traditional cylindrical batteries. This ultra-compact format will transform your operational comfort during extended use, particularly for work at height or repetitive precision applications.

Regular Maintenance

Monthly Checks

• Inspect the electrical contacts and clean them gently with a dry cloth if necessary.
• Check the overall condition of the POWERSTACK compact enclosure for cracks or damage.
• Test the functionality with different tools to ensure consistent performance.
• 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 DeWalt chargers certified as compatible with 20V MAX
• Enjoy fast charging in 40-55 minutes for optimal rotation
• Avoid leaving the battery completely discharged for extended periods.

Performance Monitoring

• Note any significant decrease in POWERSTACK battery life or energy density
• Monitor the temperature during intensive use
• Immediately replace any battery that shows signs of swelling, leakage, or abnormal behavior.

Cleaning and Maintenance

Clean the exterior of the DeWalt POWERSTACK 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 compact casing or compromise POWERSTACK technology.

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

Regularly inspect the ventilation openings and use low-pressure compressed air to remove any accumulated dust. Never attempt to open the POWERSTACK battery casing, as this will void the warranty and irreparably damage the sophisticated cellular architecture.

Precautions for Use

Never expose the DeWalt POWERSTACK battery to extreme temperatures or excessive humidity, as this could damage the POWERSTACK cell architecture and significantly reduce its performance. In particular, avoid leaving the battery in closed vehicles during the Quebec summer when temperatures can exceed 50°C.

Avoid violent shocks, drops, and impacts that could damage the internal POWERSTACK structure or electronic management system. Although the compact casing is robust, always handle the battery with care and store it in a secure location.

Never use a battery that shows signs of physical damage, cracks, swelling, or leakage. If you notice any of these problems, stop use immediately and contact Polar Industrial Equipment for advice on safe disposal and replacement.

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 DeWalt POWERSTACK battery in a cool, dry place, ideally at room temperature between 15°C and 25°C, away from direct sunlight and excessive humidity. The POWERSTACK electronic management 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 POWERSTACK cell architecture and maintains superior energy density over the long term.

Use the original packaging or a protective case to prevent accidental contact between the electrical terminals and metal objects that could cause a dangerous short circuit. Despite its compact size, the POWERSTACK battery can deliver a 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 POWERSTACK battery's fast 40-55 minute recharge time makes this periodic maintenance particularly convenient for maintaining its optimal electrochemical health.
