LTO04120-3 2.4V Ultra-Rugged LTO Cell (20,000 Cycles, -40°C to 100°C)

Product Overview

The LTO04120-3 is a precision-engineered lithium titanate (LTO) cylindrical micro-cell designed for mission-critical applications demanding extreme durability, wide temperature tolerance, and rapid power delivery. Featuring a 3mAh capacity and a 2.4V nominal voltage within an ultra-compact 4×12mm form factor, this rugged cell delivers reliable, maintenance-free power for decades in the most challenging environments—from deep-space exploration to downhole oil and gas extraction.

Exceptional Cycle Life for Decades of Reliability

Rated for more than 20,000 full charge-discharge cycles with minimal capacity fade, the LTO04120-3 far outlasts conventional lithium-ion batteries and supercapacitor alternatives. This extraordinary operational longevity enables true "fit-and-forget" deployment in remote or sealed systems where battery replacement is physically impractical or economically unfeasible, drastically reducing lifetime maintenance overhead.

Extreme Temperature Resilience Without Compromise

Engineered to perform flawlessly across an unprecedented temperature range from -40°C to 100°C, the LTO04120-3 maintains steady power delivery where standard chemistries fail. Whether deployed in Arctic monitoring stations, high-temperature industrial internet of things (IIoT) sensors, or aerospace electronics, it ensures stable voltage and capacity without the weight or power drain of auxiliary heating or cooling systems.

High-Rate Discharge Capabilities in a Miniature Format

Engineered for high performance, this micro-cell supports continuous charge and discharge rates up to 20C (60mA maximum). This high-rate capability allows for ultra-fast energy harvesting, rapid system readiness, and instant pulse-power delivery. Its robust internal construction minimizes internal resistance, keeping energy efficiency high even under aggressive cycling conditions.

Inherent Safety for Mission-Critical Deployment

LTO chemistry represents the gold standard in lithium battery safety. The LTO04120-3 features an exceptionally stable molecular structure that eliminates the risk of thermal runaway, rupture, or fire—even under severe mechanical abuse, puncturing, or electrical short-circuits. This makes it the ideal choice for medical implants, aerospace systems, and unattended remote infrastructure where failure is not an option.

Ultra-Compact Footprint for Space-Constrained Designs

With miniature dimensions of just 4mm in diameter and 12mm in length, this cell integrates seamlessly into highly restricted design envelopes. Despite its microscopic footprint, its flat, stable voltage plateau ensures consistent, predictable power management throughout its multi-decade service life.
