Charging Modes
The A46 charger has two modes for DC output voltage; Float mode and Equalize mode. Float charging mode is
used for all normal battery charging needs. Equalize mode is used when it is necessary to equalize (or balance)
the level of charge across all cells present in the battery. Refer to battery manufacturer for recommended
equalize schedule.
On a standard A46 charger, a Float/Equalize toggle switch is provided on the front panel to alternate between
charging modes. The charger will maintain the specified mode while the switch is in the corresponding position
until it is manually changed. The operator is responsible for manually changing modes, depending on battery
manufacturer recommendations.
If any options are included, refer to appropriate accessory manual for description of selecting charging modes
and equalize timer settings.

Output Voltage Adjustments
The output voltage of the A46/A46F charger is set to a default value, refer to descriptions below, but should be
adjusted to meet the battery manufacturer recommendations. A resistor with two slider bands is provided for
adjusting the float and equalize voltages. Adjustments can be carefully made with the charger energized until
the desired voltage is achieved, refer to descriptions below for charger specific notes. If adjustments are
required, refer to Figure 7.

3.4.1 A46 Output Voltage Adjustments
The A46 must be connected to batteries while adjusting the output voltage. The batteries should be fully
charged with minimal current draw from the charger. Immediate change in voltage might not be seen due to
the backfeed of the battery voltage.
3.4.2 A46F Output Voltage Adjustments
The A46F output voltage should be adjusted without anything connected to the output. The output voltages
should be set to battery manufacturer recommendations prior to connecting to battery. Adjustments with the
battery connected to the charger are also possible, but immediate change in voltage might not be seen due to
the backfeed of the battery voltage.
