AGM• – Set button to STANDARD. The Absorbed Glass Matt construc-
tion allows the electrolyte to be suspended in close proximity with the
plate’s active material. In theory, this enhances both the discharge and
recharge efciency. Actually, the AGM batteries are a variant of Sealed
VRLA (valve regulated lead acid) batteries. Popular uses include high
performance engine starting, power sports, deep cycle, solar and storage
battery. AGM batteries are typically good deep cycle batteries and they
deliver best life performance if recharged before the battery drops below
a 50 percent charge. If these AGM batteries are completely discharged,
the cycle life will be around 300 cycles. 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 INSTRUCTIONS11.
OVERVIEW11.1
To use this battery charger, rst, 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 charge is com-
plete, the charger will switch to Maintain Mode and the CHARGED (green)
LED will be lit.
