This charger features user selectable 2 or 3 stage charging. The charging prole is selected by
moving the slide switch on the front panel up to 3 stage or down for 2 stage charging.
A two-stage charger provides a constant current until the battery reaches its rated capacity
and then switches to a “oat” voltage. The current then reduces as necessary to maintain
the battery at the oat voltage. The charger can be connected to the battery indenitely and
will provide the appropriate prole. A two-stage charger is recommended in most instances
since it is the most versatile and can be permanently connected to attenuate the characteristic
discharge of unused batteries. A load can be put on the battery or batteries without altering
its ability to keep the battery at optimal charge.

this voltage at the output terminals of the unit with a good digital voltmeter. As shipped from
the factory, the unit is preset for a oat voltage of 13.6, 27.2 or 36.3 VDC, which is generally
recommended for lead-acid batteries. The output adjust potentiometer is located to the right
of the 2 stage / 3 stage select switch. If you wish to adjust this voltage, reach in with a very
small at blade screwdriver to rotate the potentiometer. Please Note that this adjusts both the
oat and absorption voltages at the same time. Clockwise increases the output voltage, and
counter clockwise decreases it. It is advisable to check with the battery manufacturer before
changing the oat voltage.
