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). The operating temperature range is -40°C to +100°C. The storage temperature range is -20°C to +70°C.
