K. BATTERY TYPE SELECTOR SWITCH
This two position switch groups Deep Cycle and Maintenance Free batteries together In
one position and conventional type batteries in the other position. The conventional setting
regulates the charge voltage at 13.8 +/-.2 volts while the Deep Cycle regulates at 14.2 +/
-.2 volts.
Some battery manufacturers do not recommend using the Deep Cycle setting their batter-
ies. This is usually, but not always indicated on the battery, check with the manufacturer.
Never use the Deep Cycle setting on conventional type batteries, over charging may oc-
cur.
L. AUTOMATIC FEATURES
When a battery approaches the full charge state, charge current will begin to cycle on
and off every few seconds as indicated by the Ammeter. As the battery continues to charge,
off time will increase. In the convention position, off time may reach 30 minutes
with an on time of only a few seconds. Off time for the deep cycle position is somewhat
shorter. Time will vary depending on bakttery size and condition.
No sparks should occur when the battery clips come together or when connected to a
battery, even if connected in reverse polarity. Charge current will only flow when properly
connected and after a 3 to 5 seconds delay. The charger will not respond to a battery so
depleted of charge that its terminal voltage is less than 3 volts.
M. AMP METER
1. This gauge indicates the amount of charge current drawn from the charger by the
battery. The battery will draw less current as it approaches the full charge state.
N. BATTERY CHARGING
1. Review section D.
2. Before making any connections to the charger, set battery type switch and charge rate
switch to the appropriate nettings. Then connect to a 12 bolt battery as outlined in
section G. Then plug AC power cord into a 120V AC outlet.
O. CHARGE PERIOD
The time required to bring a battery to the full charge state depends on battery size in
Ampere hours (AH), amount of charge in the battery and the Ampere rate the battery is
being recharged at. In using this chart, first locate battery size in AH. Recharge time is
located below the intersection of battery size and the diagonal lines representing percent
of charge in the battery. Chart is based on a 10 Amp charge rate, for a 2 Amp charge
multiply charging time by 5.
