TIME (Timer – Range: 10 min to 120 min) •
Used only in manual mode, the main function of the timer is to prevent
over charging while allowing a battery time to obtain a satisfactory
charge. To properly set the timer, you must know the size of the battery
in ampere hours or reserve capacity in minutes and the state of charge.
Often the state of charge is not known, this is one reason why the timer
was limited to 2 hours. With the aid of a battery load tester, the state of
charge can be obtained within a few seconds. For example, the aver-
age size automotive battery at a 50% state of charge will require 1 to 1½
hours of charging at a 40 amp rate to reach the full charge state. For the
same battery with the timer set to its maximum, 2 hours, over charging
will occur, but is not likely to cause harm to a battery that was otherwise
in good condition. When the charge state is not known, start out with a
timer setting of one hour or less.
Hold: • This position defeats the timer function, allowing for continu-
ous operation. Use when you want to charge more than 2 hours. Be
sure to monitor the charging procedure and stop it when the battery
is charged. Not doing so may cause damage to your battery or may
cause other personal property damage or personal injury
MODE Button
Use this button to select between the AUTOMATIC CHARGE, MANUAL
CHARGE and FLASH REPROGRAM function. See Operating Instructions
section for details of these functions.
Battery Type Button
Use this button to set the type of battery to be charged to STANDARD or
GEL CELL.
Regular • – Set button to STANDARD. 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 en-
gines) 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 button to STANDARD. Deep-cycle batteries are usu-
ally 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.
