The period of one cyclic performance is 10 seconds which consists of, in sequential order, bar code reading (1.5 sec.), transferring data (1 sec.), receiving data (1 sec.), and waiting to receive data (6.5 sec.). In this operating mode, the new large-capacity battery will last approximately 60% longer than DT-823LI Lithium-ion battery. **The communication ranges may vary depending on the surroundings.
