Its rechargeable counterpart, the 15270, is tailored to provide a more extended battery service and keep operating costs low. Its remarkable shelf life is ideal for your torch, camera, and other portables. The CR2 battery is a go-to choice for your devices.
Reputationally, rechargeable 15270s last longer, provide value for money and outperform their primary CR2 counterpart. Consequently, a “protected” 15270 has a capacity in the range of 400-600 mAh.įull compatibility between the non-rechargeable CR2 and the 15270 is achieved through a BMS that lowers the output voltage to 3.0V. The 15270 comes with a built-in Battery Management System (BMS) that protects the battery from overheating and overcharging. The Lithium Manganese Oxide (LiMn2O4) and the Lithium Iron Phosphate (LiFePO4) chemistries are the most common. High capacities, but draw a limited current amount. Slightly lower capacities, but still deliver large currents. Working temperature: on charge: 0 to 45℃ discharge: -20 to 60℃.Constant discharge current: Standard: 0.2C, continuous: 1C.It can be charged many times over without a “ lazy battery effect.” It has a slightly smaller dimension (15 by 26.6mm) compared to primary CR2 models. It is a rechargeable lithium-ion battery packaged as a single prismatic cell and configured in 1-parallel, 1-series fashion. pulse of 900 mAĨ50 mAh (down to 2.0V, 15270 (or RCR2) has popularly been nicknamed the “rechargeable CR2”. pulse of 900 mAĨ00 mAh (down to 1.8V, drain of 20mA, with a max. pulse of 900 mAĬontinuous drain of 10mA, with a max.

It has a super-high discharge rate because of the manganese oxide in its positive electrode and the spiral nature of its polar plate.Īdditionally, the battery is equipped with a Positive Temperature Coefficient (PTC) safety device to limit current during short circuit conditions. Its technology consists of lithium, alkaline, and Li-Ion. The CR2 is a 3-volt battery measuring 27mm (length) and 15.6mm (diameter). Today’s reading will give you a better understanding of the CR2 battery and its rechargeable replacement. This makes them excellent for standby/emergency devices like panic lights, EDC flashlights, and medical equipment. For example, the Energizer brand stresses their batteries more than other manufacturers, ensuring comparative endurance under high strain.Ī typical battery lasts between 3 and 10 years. The shelf life of a CR2 battery depends on the model and the brand.

That’s because their compact nature makes them an excellent choice for portable electronic devices.ĬR2 lithium batteries are a primary cell. Photo batteries (such as the CR2) are generally of this type.
The term CR2 denotes a standard, cylindrical-type lithium battery. The world glorifies the CR2 lithium battery used in cameras, golf rangefinders, weapon-mounted lights, EDC flashlights, and security devices.
