- Lithium Ion Technology High-energy-density advanced chemistry that optimizes cell durability and minimizes heating under normal use.
Product Benefits:
- High Autonomy: A high capacity of 4000mAh with a continuous power delivery of up to 60W, ideal for long use without interruptions.
- Economy and Sustainability: Supports more than 300 lifecycle cycles, reducing costs and preventing waste associated with disposable batteries.
- Versatile Compatibility: Perfect for devices compatible with the 21700 standard, including advanced Mods, high-power tactical flashlights, and portable power tools.
- Everyday Convenience: Design focused on maximum energy density and fast response in pulses up to 100W.
Safety and Care:
- CRITICAL SAFETY WARNING (Lithium Batteries): Industrial lithium cells store a massive amount of energy. NUNCA Do not transport or store loose batteries in bags, backpacks, or pockets with keys, coins, or any metal objects. Direct contact closes the electrical circuit, causing immediate short circuits with a high risk of explosion or fire. Always use proper protective boxes or sleeves and insulators.
- Inspect Before Use: Visually inspect the cell regularly. If you notice deformations in the structure, dents or tears in the outer insulating plastic wrap, stop using it immediately. Find replacement sleeves and accessories directly on our site.
- Pairing in Teams: In devices that require more than one battery, always use strictly identical cells ("matched") in terms of brand, model, capacity and lifecycle.
- Technical Limits: Operate your equipment within the recommended margins and never exceed the continuous discharge limit of 20A (60W) or the pulse limit of 45A (100W).
- Safe Charging: Perform charging cycles on non-flammable surfaces and under supervision. Strongly recommended to use a appropriate battery charger external and to preserve the chemical health of the cell (maximum charge limit: 4A).
- Ecological Disposal: When the battery reaches the end of its life, never discard it with ordinary waste. Send it for recycling at a designated battery drop-off or authorized electronic waste collection point.
Usage Instructions:
- Initial Calibration: Before the first practical use cycle, perform a full charge of the battery in a dedicated external charger to optimize its lifespan.
- Respect Polarity: When inserting the cell into the device battery compartment, carefully validate the correct orientation of positive and negative terminals (+ and -).
- Prevention of Deep Discharges: Charge the battery as soon as you notice a substantial drop in performance or when the level indicates about 20-30%, extending the internal chemistry durability.
- Safe Storage: If you do not plan to use the batteries for a long period, store them with about half charge in a dry, cool place completely insulated from direct heat sources.
- Contact Hygiene: Regularly clean the battery's flat contacts and the device's contact pins to prevent electrical faults or conductivity losses.
Usage Tips:
- When traveling or on the move, always remove the cells from the devices and transport them safely and individually in a suitable carry case to protect against impacts.
- If you detect any sign of operational anomaly (such as sudden extreme heating, unusual odors or liquid leakage), stop use immediately and contact our technical support.
- Handling high-drain cells requires knowledge, care and strict safety attentionto provide a clear understanding of how to operate these items responsibly responsible for a protected experience, consult the Frequently Asked Questions Contrast Vaping® available here.
