3.6 v lithium battery 18650

Superior Safety Features

Superior Safety Features

The 3.6V lithium battery 18650's advanced safety features set it apart in the battery market. Each cell incorporates a sophisticated protection circuit module (PCM) that actively monitors and controls various parameters during operation. This intelligent system prevents overcharging by cutting off the charging current when the cell reaches its maximum voltage, typically 4.2V. Similarly, it prevents over-discharging by disconnecting the load when the voltage drops below a safe threshold, usually 2.5V. The battery includes a pressure relief mechanism that safely vents gases in case of internal pressure buildup, preventing catastrophic failure. Thermal protection circuits monitor the cell's temperature, shutting down operation if it exceeds safe limits. These comprehensive safety measures make the 18650 one of the most reliable and secure battery options available.
High Energy Density and Performance

High Energy Density and Performance

The 3.6V lithium battery 18650 excels in energy storage capabilities, packing remarkable power into its compact cylindrical form. The advanced lithium-ion chemistry enables energy densities exceeding 250 Wh/kg, significantly higher than other rechargeable battery technologies. This high energy density translates to extended runtime for devices, with a single cell capable of delivering consistent power for hours of operation. The battery maintains stable voltage output throughout its discharge cycle, ensuring optimal device performance from start to finish. The cells demonstrate excellent rate capability, efficiently handling both high-current applications and steady, low-drain scenarios. Their low internal resistance minimizes power loss during operation, contributing to overall system efficiency.
Long-Term Reliability and Durability

Long-Term Reliability and Durability

The 18650 battery's construction emphasizes longevity and consistent performance over time. The cell's robust metal casing provides excellent mechanical protection while efficiently conducting heat away from the internal components. The battery's chemical composition is optimized for cycle stability, enabling hundreds of charge-discharge cycles while maintaining high capacity retention. The sophisticated manufacturing process includes precise electrode alignment and high-quality separator materials, reducing the risk of internal shorts and ensuring reliable operation. These batteries demonstrate remarkable resilience to environmental factors, maintaining performance across a wide temperature range. The cell's design incorporates redundant safety features and quality materials that contribute to an extended service life, often exceeding five years under normal usage conditions.
