BATTERY TYPE BUTTON
Use this button to select the type of battery.
NOTE:
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.
NOTE:
When the “LITH” battery type is
selected, only the “12V” voltage setting is
available.
STD (Standard) –
Used in cars, trucks
and motorcycles, these batteries have
vent caps and are often marked “low
maintenance” or “maintenance-free”.
This type of battery is designed to
deliver quick bursts of energy (such as
starting engines) and has a greater plate
count. The plates are thinner and have
somewhat different material composition.
Standard batteries should not be used for
deep-cycle applications.
Deep-Cycle –
Set button to
AGM
.
Deep-cycle batteries are usually marked
as “Deep-Cycle” or “Marine”. Deep-cycle
batteries are usually larger than the
other types. This type of battery has less
instant energy but somewhat greater
long-term energy delivery than regular
batteries. Deep-cycle batteries have
thicker plates and can survive a number
of discharge cycles.
AGM –
The Absorbed Glass Mat
construction allows the electrolyte to be
suspended in close proximity with the
plate’s active material. In theory, this
enhances both the discharge and recharge
efficiency. 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 batteries.
AGM batteries are typically good 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 completely
discharged, 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
AGM
. The Gel Cell
is similar to the AGM style because the
electrolyte is suspended, but different
because 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 recharge 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
applications and may last a bit longer in hot
weather applications. If the incorrect battery
charger is used on a Gel Cell battery, poor
performance and premature failure is certain.
LITH (Lithium Ion, LiFePO
4
only) –
The LiFePO
4
(Lithium Iron Phosphate)
battery is lithium-ion based and offers good
safety characteristics. The LiFePO
4
cell
has a very constant discharge voltage.
This allows the cell to deliver virtually full
power until it is discharged. Because of the
nominal 3.2 VDC output, four cells can be
placed in series for a nominal voltage of
12.8 V. This comes close to the nominal
voltage of six-cell lead-acid batteries. This
makes the LiFePO
4
a good replacement
for lead-acid batteries in applications such
as automotive and solar. Like a gel cell, the
LiFePO
4
cell is sensitive to overcharging.
Its cells are balanced before they are
assembled, and an internal protection
system is implemented, preventing too
deep a discharge.
START/STOP BUTTON
Use this button to start or stop the charging
process, after the battery is properly
connected and battery voltage and type
have been selected. The display will briefly
show “ON” when the START/STOP button
is pressed. After charging has started,
pressing the START/STOP button will
cause the display to briefly show “OFF”.
CHARGING LED INDICATORS
Charging (yellow/orange) lit –
The charger is charging the battery.
Charged/Maintaining (green) lit –
The battery is fully charged and the
charger is in maintain mode.
Reversed Clamps (red) flashing –
The connections are reversed.
NOTE:
See
Operating Instructions
for a
complete description of the charger modes.
