Digital Display 10.1
The Digital Display gives a digital indication of voltage or % of charge,
depending on the Display Mode chosen.
Display Mode Button 10.2
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.
Charge Rate Button 10.3
Use this button to set the maximum charge rate.
2A Slow Charge Rate • – Intended for charging small batteries such
as those commonly used in garden tractors, snow mobiles and motor-
cycles.
6A Medium Charge Rate • – Use for charging automotive, marine and
deep-cycle batteries. Not intended for industrial applications.
10A Fast Charge Rate • - Use for charging automotive and light truck bat-
teries. Not intended for industrial applications.
Battery Type Button 10.4
Use this button to set the type of battery to be charged.
Regular • – This battery type is usually used in cars, trucks and motor-
cycles. 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 • – 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 Matt 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. Actu -
ally, 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 bat-
teries 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.
