LITHIUM CR CYLINDRICAL SERIES FOR CONSUMER
(NON-RECHARGEABLE)
Panasonic Photo-Lithium CR type cylindrical batteries come as either single cells
or dual cell packs. All cylindrical type Manganese Dioxide (CR series) Lithium
batteries feature a spiral structure. With the enlarged electrode surface areas, they
permit a current as high as several amperes to be drawn.
*1 Capacity based on standard drain and cut off voltage down to 2.0V or 4.0V at 20°C.
*2 Operating temperature range is from - 40°C ~ + 100°C.
*3 The illustration shows only one example of Lithium battery structure.
