LITHIUM CR1632 3V RENATA Batteries

Battery storage life can depend on a variety of factors including material quality, storage conditions, storage time, humidity, physical damage, or temperature. Ideally you would want a battery made of high quality materials, stored in a climate controlled and dry area, with no physical damage. Energizer claims that their lithium coin cell batteries have up to 10 years of shelf life when properly stored. As far as service life this will depend greatly on the application. The Panasonic lithium coin CR1632 batteries have a long shelf life of up to 10 years: they still have 90% of their original capacity. The chemical stability, which is the combination of lithium and manganese dioxide, is the reason for this. Nominal capacity: 120mAh (on continuous discharge at 20℃ under 15kΩ load to 2.0V end-voltage) 2.4 Outer dimensions: Outer dimensions shall be as shown in Fig. 1, Battery Dimensions.
