LFP18650-1500mAh 3.2V 1500mAh Lithium-iron Phosphate Cell

Product Overview

The LT-LTO04150-5 is an ultra-compact, high-performance rechargeable Lithium-Titanate (LTO) battery cell engineered for precision instruments and micro-electronics. Operating at a nominal voltage of 2.4V with a 5mAh capacity, this miniature cell utilizes an advanced LTO anode chemistry to deliver an exceptional 20C high-discharge rate and superior thermal stability. Designed for mission-critical applications where safety, rapid charging, and extreme longevity are paramount, it serves as the ultimate reliable power solution for compact industrial, medical, and smart devices.

Core Specifications

The Nominal Capacity of the cell is 5mAh when discharged at a 1C rate under standard room temperature (25 +/- 5 deg C). The cell operates at a Nominal Voltage of 2.4V (representing the average discharge voltage at 1C). Engineered for high-drain performance, it delivers a massive Maximum Continuous Discharge Rate of 20C, providing reliable and stable power output for precision electronics. The recommended Operating Temperature range spans from -20 deg C to 60 deg C, ensuring excellent thermal stability and safety under diverse environmental conditions. For optimal longevity, the recommended Storage Temperature range is -20 deg C to 35 deg C in a low-humidity environment (less than or equal to 90% RH).

Cycle Life

Utilizing advanced Lithium-Titanate (LTO) chemistry, the LT-LTO04150-5 offers an unparalleled cycle life compared to traditional lithium chemistries. Under standard test conditions (1C charge/discharge, 100% DOD at room temperature), the cell is engineered to retain ≥80% of its initial capacity after 7,000 to 10,000+ cycles. This extraordinary longevity makes it an ideal choice for maintenance-free, long-lifespan applications such as precision instruments, smart industrial sensors, and IoT devices.

Rate Performance

The LT-LTO04150-5 exhibits exceptional high-rate capability, allowing for ultra-fast charging and high-power delivery without significant capacity degradation. Both charge and discharge capacities at high rates (up to 20C) retain greater than or equal to 95% of their initial baseline capacity. This robust performance enables the miniature cell to fully charge in just a few minutes and comfortably handle high-frequency micro-pulses required by advanced precision instruments.

Temperature Performance

The LT-LTO04150-5 features exceptional thermal stability and performs reliably across a wide temperature spectrum. At 0 deg C, the cell retains greater than or equal to 95% of its standard charge capacity and greater than or equal to 85% of its discharge capacity. Even in extreme cold environments down to -20 deg C, it maintains outstanding functionality, retaining greater than or equal to 85% charge capacity and greater than or equal to 70% discharge capacity. This superior low-temperature performance makes it an ideal power solution for outdoor precision instruments and unheated industrial environments.

Storage and Self-Discharge

The LTO04150-5 features an exceptionally low self-discharge rate due to the chemical stability of its lithium-titanate anode. Following 28 days of standard storage at room temperature (25 +/- 3 deg C), the cell retains greater than or equal to 95% of its residual capacity and recovers greater than or equal to 98% of its initial capacity upon recharging. For long-term storage, it is recommended to maintain the cell at a 50% to 100% State of Charge (SOC) within a clean, dry environment at a temperature range of -20 deg C to 35 deg C and a relative humidity of less than or equal to 75%. A top-up charge is recommended once every 12 months to maintain peak performance.
