Description
The GR5300 is ideal for standalone charging of 1 to
multiple AA or AAA NiMH “loose” cells. NiCd cells
can also be charged. Temperature, voltage and
charge time are monitored to provide proper
fast/slow charging control algorithms for Nickel
Metal Hydride (NiMH) batteries. The GR5300
detects the battery chemistry and proceeds with the
optimal charging and termination algorithms. This
process eliminates undesirable undercharged or
overcharged conditions and allows accurate and
safe termination of fast/slow charge. Battery tests
are included to detect defective or inappropriate
cells such as Alkaline primary batteries. The
GR5300 supports a parallel charging topology.
The GR5300AA supports one loop single cell
charging topology, with monitoring and controls of
cell.
The GR5300DA supports one loop two parallel cells
charging topology, with the same monitoring and
controls of two cells.
