3.6V 750mAh Li-ion 14500 Battery Pack
Wide-Temperature 3.6V AA 14500 li-ion battery serves as an ideal power solution for many industrial and outdoor devices that still rely on NiMH AA cells due to their compact size and easy replacement. Unlike NiMH batteries, which suffer from significant performance loss under extreme temperatures or high-current loads, this advanced Li-ion pack from CM Batteries — the 14500R High-Temperature model — combines wide operating tolerance (-40 ℃ to 85 ℃), greater energy density, and integrated safety mechanisms. It provides a drop-in lithium upgrade for existing NiMH-based systems, allowing equipment manufacturers to enhance device reliability and lower maintenance costs without the need for mechanical redesign.
Key features：
- Drop-in Li-ion replacement (AA size)：Seamlessly fits existing NiMH housings, eliminating the need for design changes.
- Temperature Endurance: Discharge from -40℃ to +85℃, charge from -20℃ to +60℃.
- High Discharge Rate: Up to 5C continuous for demanding power loads.
- Built-in PCB protection: Prevents overcharge, over-discharge, and short-circuit, ensuring long-term stability in industrial deployments.
- Extended cycle life: Delivers 3–5× the lifespan of NiMH batteries, reducing maintenance and replacement frequency.
