Patco manufactures three Li-Ion chargers, designated Model 6100, Model 6200, and the Model 6040. All three of these chargers utilize the Li-ion charge algorithm described on the previous page. These three chargers differ in power out to the battery, and how the charge current is generated.

The Model 6100 is a universal input charger, operating from 95 to 265 VAC, 50/60Hz. Its power envelope is 32 watts, meaning that the bulk charge current can be found by dividing the battery voltage into 32, limited by 2.5 amps maximum charge current.

The Model 6200 is also a universal input charger, with a power envelope of 80 watts. As before, the bulk charge current can be found by dividing the battery voltage into 80, limited by 5 amps maximum charge current.

Model 6100/6200

To specify the charger, select the appropriate model, specify the number of cells, and then the constant current phase current. Use the following format to do so:

AAAA-B-CC.

AAAA is the model number, such as 6100. B is the cell count, from one to four. CC is the constant current charge current in units and tenths of an amp.

For a Model 6100 charging 3, 5 amp hour Li-Ion cells in series at a 2.5 amp rate, the specification would read:                           6100-3-25
