14430 Batteries – Compact AA-Derived Cylindrical Cells, Short Length with High Energy Density

Welcome to our 14430 Batteries collection. The 14430 lithium-ion cell (approx. 14mm diameter × 30mm length) is a "short-body derivative" of the standard AA (14500) form factor. It retains the same 14mm diameter as AA/14500 while significantly reducing length to approximately 30mm—specifically engineered for devices with tight length constraints that still require a 3.7V Li-ion voltage platform. Despite its compact volume, the 14430 delivers usable capacities from 200mAh to 400mAh and is available in both NMC (ternary lithium) and LiFePO₄ (lithium iron phosphate) chemistries. It serves as the ideal power upgrade for compact flashlights, headlamps, portable medical devices, wireless sensors, smart home terminals, and any device with a short AA battery compartment.

Core Advantages of 14430 Batteries

AA Diameter, Shorter Length: Approximately 14mm diameter (same as AA/14500) with a length of only ~30mm (about 20mm shorter than 14500). Perfect for length-sensitive devices that cannot accommodate standard 14500 cells.
High Voltage Platform: NMC versions deliver a nominal 3.7V (full charge 4.2V)—approximately 3× the voltage of NiMH AA (1.2V)—providing more power and brighter illumination.
Rechargeable – Economical & Eco-Friendly: Supports 500–1,000+ charge/discharge cycles. Replaces disposable lithium primaries or NiMH cells for lower long-term cost and reduced battery waste.
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.
Low Self-Discharge: Monthly self-discharge as low as 3% ensures readiness even after extended storage—ideal for intermittently used devices.
Lightweight Design: Weighing only 15g–18g per cell—lighter than comparable NiMH cells—perfect for weight-sensitive portable devices.

⚠️ 14430 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 Length Matching: The 14430 is approximately 20mm shorter than a 14500 and 10mm shorter than a 14400. Carefully measure your device's battery compartment length before purchase to avoid contact issues or fitment problems.
Not a Universal AA Replacement: 14430 voltage (3.7V) is significantly higher than standard 1.5V AA cells. Connecting two 14430s in series for a 3V device may damage or destroy the device. Always confirm your device supports 3.7V Li-ion before use.
Use a Dedicated Li-ion Charger: 14430 cells require a Li-ion-specific charger. Do not use NiMH/NiCd chargers. Select a universal charger that supports 14500 and shorter formats.
Avoid Over-Discharge: Stop discharging when voltage drops below 2.5V–2.8V (NMC) or 2.0V–2.5V (LiFePO₄). Recharge promptly to prevent permanent capacity loss.
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.
