Grepow’s newly designed Lithium based button cell is the replacement for old school coin cell battery technology. With a maximum discharge rate of 20C all the power is just a zap away. Our innovated steel shell packing is design and production patented.
Grepow provides the custom button battery solution, 100% match your product structural design, tailor-made the Diameter (9~16mm), Height (2.5~6.0mm), or shape.
Grepow utilizes stacking technology to produce these new rechargeable button cell batteries. The stacking method improves the utilization of the internal structure. By utilizing the stacking method, we are able to improve the continuous current rating along with drastically reducing the internal resistance compared to traditional coin cells.
