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 wood, metal, or concrete dust. Never attempt to open the battery case, as this will void the warranty and present significant safety risks.

Precautions for Use

Never expose the PowerPack battery to extreme temperatures above 50°C or below -20°C, as this could damage the lithium-ion cells and significantly reduce its performance and lifespan. In particular, avoid leaving the battery in closed vehicles during the Quebec summer.

Avoid violent shocks, drops, and impacts that could damage the internal structure or electronic protection system. Although the overmolded base provides excellent protection, 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, even partially.

Storage Tips

Store your PowerPack battery in a cool, dry place, ideally at room temperature between 15°C and 25°C, away from direct sunlight and excessive humidity which could cause corrosion on the electrical contacts.

For extended storage of more than one month, keep the battery at a charge level of approximately 40 to 60% rather than fully charged or completely discharged. Storing the battery fully charged or completely discharged can reduce its overall lifespan and maximum capacity.

Use the original packaging or a protective case to avoid accidental contact of the electrical terminals with metallic objects such as keys, coins or tools that could cause a dangerous short circuit.

Check and recharge the battery at least every 3 months, even if it is not in use, as lithium-ion batteries undergo a natural self-discharge of approximately 1 to 2% per month. This practice maintains its electrochemical health and ensures it is ready for immediate use.
