deep cycle batteries and they deliver best life performance if recharged
before the battery drops below the 50 percent discharge rate. If these
AGM batteries are discharged to a rate of 100 percent the cycle life will
be 300 plus cycles and this is true of most AGM batteries rated as deep
cycle batteries.
GEL
• – Set button to GEL CELL. The Gel Cell is similar to the AGM style
because the electrolyte is suspended, but different because technically
the AGM battery is still considered to be a wet cell. The electrolyte in a
GEL cell has a silica additive that causes it to set up or stiffen. The re-
charge voltages on this type of cell are lower than the other styles of lead
acid battery. This is probably the most sensitive cell in terms of adverse
reactions to over-voltage charging. Gel Batteries are best used in VERY
DEEP cycle application and may last a bit longer in hot weather applica-
tions. If the incorrect battery charger is used on a Gel Cell battery, poor
performance and premature failure is certain.
Gel Cell and some AGM batteries may require a special charging rate.
Batteries should be marked with their type. If charging a battery that is not
marked, check the manual of the item that uses the battery.
OPERATING INSTRUCTIONS 11.
OvERvIEW 11.1
To use this battery charger, first, select an unused outlet from the eight
available and connect the battery and AC power, if necessary, following
the precautions listed under sections 6 and 7. Then, select the appropriate
BATTERY TYPE for your battery and press START. This section explains
a few details.
CHARGING:
11.2 The CONNECTED (red) LED will not light continuously until
a battery is detected. If the charger does not detect a properly connected
battery, the CONNECTED LED will not light. Charging will not begin until
the CONNECTED LED comes on. When charging begins, the CHARGING
(yellow) LED will be lit.
AUTOMATIC CHARGE:
11.3 Once the battery type is selected, press the
START button and the charger automatically selects the charge rate
based on battery size and voltage. When an automatic charger is com-
plete, the charger will switch to Maintain Mode and the CHARGED (green)
LED will be lit.
ABORTED CHARGE:
11.4 If charging cannot be completed normally, charging
will abort. When charging is aborted, the charger’s output is shut off. The
CONNECTED LED will be lit and the display will read BAD BAT. In this
case, the charger ignores all buttons. To reset after an aborted charge,
press the START/STOP button to turn the charger off.
