Samsung INR21700-40T Battery cell boasts an impressive energy capacity of 4,000 mAh, consistently delivering a robust 45 amp Continuous Discharge/Drain Rating. Remarkably, this exceptional performance is achieved without the necessity for temperature mitigation measures. Even when subjected to continuous discharge/drain of up to 40 amps, the cell's temperature rise remains constrained to a mere 67 degrees Celsius or 153 degrees Fahrenheit. Such attributes render this cell suitable for empowering devices of up to 95 watts per cell, while ensuring steadfast functionality over prolonged durations.

The 40T excels in maintaining unwavering output stability during extended utilization, making it an optimal choice for moderate wattage requirements. Its distinctive value lies in striking an impeccable balance between High Capacity and Ultra-High Discharging/Drain capabilities, all while maintaining peak performance standards.

Rechargeable & Reusable

Invest in a rechargeable battery that will last for years to come– this battery can be recharged 250+ times.

High Discharge Rate

45A max continuous discharge rate for high-drain electronics, great for making battery packs for devices that require minimum discharge rates.

3 Year Shelf Life

Stock up and store spare batteries with confidence– lithium ion batteries have a 3+ year shelf life, ensuring you always have a fresh replacement when you need it.

Notable Features

4,000mAh capacity provides long runtimes for all your devices
Flat top terminal is perfect for use in making OEM battery packs

Note (*¹): Protection function of the battery pack should be set within the specified charge,
discharge and temperature range in the Cell Specification.

Note (*²): Discharge OTP(over temp. protection) should not be over 80℃ of the cell
surface temperature. Protection set should be based on the location of the cell
surface with the highest temp increase part of the battery pack.

Note (*³): If the cell is kept as ex-factory status (30% of charge),
the capacity recovery rate is more than 90%.
