LTO10450 2.4V 180mAh Cylindrical Cell 10000 Cycles 20C Charge Discharge -40°C to 70°C
Tiny LTO Cell with Monster Power
The LTO10450‑180mAh is a 2.4V cylindrical lithium titanate cell that punches well above its weight. With a nominal capacity of 180mAh and the ability to charge and discharge at 20C (3.6A), this tiny powerhouse delivers exceptional power density in a compact 10450 form factor. The LTO chemistry provides ultra‑long cycle life (10,000 cycles), outstanding low‑temperature performance (‑40°C operation), and industry‑leading safety—passing nail penetration, crush, and short‑circuit tests with no fire or explosion.

Designed for Wearables and Small Devices
This LTO cell is ideal for IoT sensors that need to wake up, transmit, and go back to sleep—repeatedly and reliably. It powers wireless communication modules (RF, Bluetooth, LoRa), wearable health monitors, medical patches, portable instruments, and backup power for critical electronics. The 10450 form factor fits where larger cells won't.
Storage and Handling
Store at 10‑30% SOC in a clean, dry, ventilated room at ‑5°C to 28°C. Recharge every six months. Ship at approximately 30% SOC. Avoid short circuits, reverse polarity, overheating during soldering, and mechanical damage.
