10370 Batteries – Ultra-Compact Cylindrical Li-ion Cells, The Ideal Power Source for Space-Constrained Devices
Welcome to our 10370 Batteries collection. The 10370 lithium-ion cell (approx. 10mm diameter × 37mm length) is one of the most compact formats in the cylindrical battery family. Shorter than the common 10440 (AAA size), it is purpose-built for micro-devices with extreme space constraints. Despite its diminutive size, the 10370 retains the core advantages of cylindrical cells: robust construction, excellent consistency, and high energy density. Mainstream 10370 capacities range from 100mAh to 450mAh, available in both NMC (ternary lithium) and LiFePO₄ (lithium iron phosphate) chemistries, making them the ideal power core for mini flashlights, vaping devices (e.g., IQOS), electric toothbrushes, Bluetooth headsets, wearables, and various micro-sensors.
Core Advantages of 10370 Batteries
- Ultra-Compact Form Factor: With a diameter of just ~10mm and a length of only ~37mm—shorter than AAA-sized 10440 cells—the 10370 easily fits into extremely tight micro-device compartments.
- Flexible Chemistry Options: Available in both high-energy NMC (3.7V) and inherently safe LiFePO₄ (3.2V) formulations to meet diverse voltage and safety requirements.
- Excellent Cycle Life: Premium 10370 cells support 500 to 1,500+ charge/discharge cycles, with LiFePO₄ versions offering particularly impressive longevity—significantly reducing battery replacement frequency in micro-devices.
- Low Self-Discharge: Monthly self-discharge can be as low as 3%, ensuring readiness even after extended storage—ideal for intermittently used micro-devices.
- Wide Operating Temperature: Discharge temperature range from -20°C to 60°C and charge from 0°C to 45°C, adapting to diverse operating environments.

⚠️ 10370 Battery Safety Guidelines
- Voltage Platform Awareness: 3.2V LiFePO₄ and 3.7V NMC cells cannot be mixed or charged with the same charger. Always verify device and charger compatibility.
- Precise Dimensional Matching: The 10370 is approximately 7mm shorter than the 10440. Measure your device's battery compartment carefully before purchase to avoid poor contact or fitment issues.
- Limited Capacity – Plan for Runtime: 10370 capacity is only 1/10 to 1/20 that of an 18650. Best suited for low-power micro-devices; high-power devices will have very short runtime.
- Use a Quality Charger: Always use a reliable charger designed for Li-ion or LiFePO₄ chemistry.
- Avoid Short Circuits & Overheating: Do not short the terminals. Keep away from heat, moisture, and metal objects.
- Discontinue if Damaged: Stop using cells with torn wraps, dents, or leakage. Recycle responsibly.
