The Keeppower RCR2 (CR2-P1 / 14250) is a compact, high-performance rechargeable Lithium-ion (Li-ion) battery featuring an integrated PCB protection circuit. With its stable output and protected design, this battery is an excellent choice for specialized high-drain devices that require a sustainable and reliable RCR2-format power source.
This battery operates at a nominal voltage of 3.6V–3.7V (reaching 4.2V when fully charged). It is not a drop-in replacement for standard non-rechargeable 3V CR2 lithium batteries. Please verify that your device is explicitly rated to handle 3.6V–4.2V Li-ion chemistry before use. Additionally, due to the built-in protection circuit, physical dimensions might slightly differ from standard primary CR2 batteries.
Integrated PCB Protection: Features an onboard safety circuit (PCM) that actively protects the cell against overcharging, deep discharge, over-current, and short circuits.
Premium Quality & Lifespan: Utilizes a high-grade 14250-E520 cell core to deliver consistent capacity and a prolonged operational lifecycle.
Compatible Chargers: Must only be recharged using dedicated Li-ion smart chargers compatible with 3.6V/3.7V chemistry and capable of mechanically accommodating RCR2 sizes (e.g., Keeppower RCR2 or RCR4 chargers).
