XTAR 18650 4000mah 10A Protected

The XTAR 18650 4000mAh 10A Protected lithium-ion battery is engineered for users who demand high capacity, reliable performance, and top-tier safety in demanding applications. With a generous 4000mAh capacity, it offers significantly longer run times compared to standard 3500mAh 18650 cells, making it ideal for extended outdoor trips, emergency backup power, or continuous high-drain usage without frequent recharging.

What sets this battery apart is its ability to sustain a continuous discharge current of up to 10A, ensuring stable power delivery even under heavy load. This makes it perfect for devices that require consistent high output, such as high-lumen LED flashlights. The 10A rating is maintained safely thanks to the built-in protection circuit, which prevents overheating, voltage spikes, and other electrical faults that can compromise performance or safety.

Safety is a core design principle. The XTAR 18650 4000mAh 10A is equipped with a comprehensive protection circuit that includes over-discharge protection, over-charge protection, and short-circuit protection. These safeguards prevent damage to the battery and connected devices, extend the battery’s lifespan, and reduce the risk of thermal events. The battery undergoes extensive reliability testing under real-world conditions, ensuring consistent performance across a wide range of temperatures and usage scenarios.

While it offers higher capacity than the XTAR 18650 3500mAh 10A model, it slightly reduces the number of charge cycles—offering approximately 600+ full charge and discharge cycles. This is a trade-off typical of higher-capacity batteries, where increased energy density comes at the cost of slightly reduced longevity. However, for users prioritising runtime over maximum cycle life, the 4000mAh capacity provides a compelling advantage.

This battery is compatible with most standard 18650 chargers, making it easy to integrate into existing setups. The robust construction and high-quality materials ensure durability, even in rugged environments. Whether you're hiking in remote areas, camping off-grid, or relying on your equipment during power outages, this battery delivers dependable, long-lasting power with peace of mind.
