Display Mode Button
Use this button to set the function of the digital display to one of the
following:
• Battery % - The digital display shows an estimated charge percentage
of the battery connected to the charger battery clips.
• Voltage – The digital display shows the voltage at the charger battery
clips in DC volts.
• Alternator %
age of the vehicle's charging system connected to the charger battery
clips as compared to a properly functioning system.
Battery Type Button
Use this button to set the type of battery to be charged.
• Regular – Set the button to REGULAR. This battery type is usually
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 have a greater plate count. The plates will also
be thinner and have somewhat different material composition. Regular
batteries should not be used for deep cycle applications.
• Deep-Cycle – Set the button to DEEP CYCLE. 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 – Set the button to AGM/GEL CELL. The Absorbed Glass Matt
construction allows the electrolyte to be suspended in close proximity
with the plate's active material. In theory, this enhances both the dis-
charge and recharge efficiency. Actually, the AGM batteries are a vari-
ant 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 the button to AGM/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 recharge voltages on this type of cell are lower than the oth-
er 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 applications. If the incorrect battery charger is used on a
Gel Cell battery, poor performance and premature failure is certain.
