Description
The DS2714 is ideal for standalone charging of 1 to 4 AA or AAA NiMH "loose" cells. NiCd cells can also be charged. Temperature, voltage and charge time are monitored to provide proper fast charging control algorithms for Nickel Metal Hydride (NiMH) batteries. Battery tests are included to detect defective or inappropriate cells such as Alkaline primary batteries. The DS2714 supports a parallel charging topology, with independent monitoring and control of each cell.
