LTO04150-5 Small 2.4V 5mAh LTO Battery Cell | 20C High Discharge Rate Lithium-Titanate
The LTO04150-5 is an ultra-compact, rechargeable lithium-titanate (LTO) cell engineered for applications demanding absolute reliability, a miniature footprint, and an exceptional lifecycle. Designed to thrive where standard lithium-ion batteries fail, this tiny powerhouse delivers dependable energy under the most punishing thermal and mechanical conditions.
Extreme Thermal Resilience: Operates flawlessly across a vast temperature range from -40°C to +100°C, making it perfect for harsh industrial, outdoor, and automotive environments.
Unmatched Cycle Life: Engineered for longevity, it retains ≥80% of its initial capacity even after 25,000 cycles, virtually eliminating the need for battery replacements over the device's lifetime.
High-Rate Discharge: Supports up to a 20C continuous charge and discharge rate (100mA), effortlessly powering high-pulse wireless transmissions and peak loads.
Ultra-Safe Chemistry: Lithium-titanate chemistry is inherently stable, significantly reducing the risks of thermal runaway, shorts, or degradation under high stress.
Typical capacity is 5mAh with a tolerance of -30% to +20%. Nominal voltage is 2.4V. Internal impedance is ≤800mΩ measured at AC 1kHz after standard charge. Charge cut off voltage is 2.8V. Discharge cut off voltage is 1.8V. Standard charge and discharge current is 5mA (1C). Maximum charge and discharge current is 100mA (20C). Operating temperature range is -40°C to +100°C. Storage temperature range is -20°C to +70°C.
