Rechargeable Samsung 40T 21700 Battery - High Performance and High Drain

The Samsung 40T 21700 Battery is an absolute benchmark in the high-power cell market, being the ideal choice for those seeking the perfect balance between a massive capacity and a brutal discharge current. Developed with Samsung's cutting-edge engineering, this cell offers consistent and safe performance for all types of regulated high-power electronic devices. Upgrade your equipment with one of the most reliable batteries in the ecosystem.

Features:

  • Brand: Samsung
  • Capacity: 4000mAh, ensuring longer autonomy and extended usage between charges.
  • Continuous Discharge Current: 30A, providing a stable and powerful energy delivery for demanding setups.
  • Type: 21700, compatible with the new generation of Mods and high-drain electronic equipment that support this format.
  • Lithium Ion Technology: Advanced INR chemistry that optimizes cell life cycles and mitigates overheating under normal usage conditions.
  • Industrial Construction: Manufactured with highly durable materials, ensuring a robust and reliable structure for everyday use.

Product Benefits:

  • Uninterrupted Autonomy: One of the largest capacities on the market (4000mAh) combined with a linear voltage stability throughout the entire discharge curve.
  • Economy and Sustainability: Highly reusable cell with support for hundreds of charging cycles, eliminating the need and waste of disposable batteries.
  • Versatile Compatibility: Ideal for a wide range of high-performance applications, such as advanced tactical flashlights, portable power tools, photographic equipment, and devices compatible with the 21700 standard.
  • Daily Convenience: Compact format focused on maximum energy density, ready for immediate delivery of stable energy.

Safety and Care:

  • CRITICAL SAFETY WARNING (Lithium Batteries): Industrial INR cells store a massive amount of energy. NEVER transport or store loose batteries in bags, backpacks, or pockets with keys, coins, or any metallic objects. Direct contact closes the electrical circuit, causing immediate short circuits with a high risk of explosion or fire. Always use appropriate protective boxes or covers and insulators.
  • Inspect Before Use: Visually inspect the cell regularly. If you notice deformities in the structure, dents, or tears in the outer insulating plastic wrap, stop using it immediately. Find replacement covers and accessories directly on our site.
  • Manage in Teams: On devices that require more than one battery, always use cells that are strictly identical ("matched") in terms of brand, model, capacity, and lifecycle.
  • Technical Limits: Operate your equipment within the recommended margins and never exceed the battery's continuous discharge limit of 30A.
  • Safe Charging: Perform charging cycles on non-flammable surfaces and under supervision. It is highly recommended to use an appropriate external battery charger to preserve the chemical health of the cell.
  • Eco-friendly Disposal: When the end of life is reached, never discard the battery in regular trash. Recycle it at a battery recycling bin or authorized electronic waste collection point.

Usage Instructions:

  • Initial Calibration: Before the first practical use cycle, perform a full charge of the battery on a dedicated external charger to optimize its lifespan.
  • Respect Polarity: When inserting the cell into the electronic device compartment, carefully verify the correct orientation of the positive and negative terminals (+ and -).
  • Prevention of Deep Discharges: Start charging the battery as soon as you notice a substantial drop in performance or when the level indicates about 20-30%, prolonging the internal chemistry's durability.
  • Safe Storage: If you do not plan to use the batteries for a long period, store them with about half a charge in a dry, cool place, fully isolated 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.

Tips for Use:

  • When moving or traveling, always remove the internal cells from the devices and transport them safely and individually in a protective carrying case against impacts.
  • If you detect any sign of operational anomaly (such as sudden extreme heating, strange odors or liquid leaks), stop using immediately and contact our technical support.
  • Handling high-drain cells requires knowledge, care and strict safety attention. For a detailed understanding of how to operate these items in a responsible way for a protected experience, consult the Contraste Vaping® FAQ (Frequently Asked Questions) available here.
