CONTROLS AND INDICATORS
C. Charging Modes
There are 4 charging modes to choose from. Pressing the MODE button repeatedly will cycle
through each of the charge modes. See below for an overview of each mode. Charging will
automatically begin about 5 seconds after the charge mode has been selected.
NOTE: The battery charger will retain the last selected mode in memory. In the event AC power is
disrupted (e.g., power failure), the charger will re-start in the last selected mode once power is
restored.

About the 2 A<>15 A mode
—To help a battery delivery its maximum performance and lifespan, it is
important to charge it at a rate that is appropriate and safe for its capacity. Charging a battery at too high a
charge rate, while fast, can overheat a battery and shorten its expected life. Conversely, charging a battery
at too low a charge rate, while safer, can take unneccessarily long and can even result in the battery never
truly reaching full charge. In the
"
2 A<>15A
"
mode, the charger starts charging at a low, safe current and
gradually increases the rate as the battery demonstrates it can accept a higher current. The result is a
balance between shortest charging time and safely charging a battery to its utmost capacity.

Amber (solid)—No battery detected. Check to ensure that clamp connections to the battery posts
are clean and solid. If connections are good, the battery is severely discharged (<1.5 V) and may
be unsafe to charge. The battery should be tested or replaced.
Red (flashing)—A fault has been detected and charging has been aborted. Check the digital
display for a Fault Code and see "Troubleshooting/Fault Codes" for possible causes and solutions.
Red (solid)—Reverse polarity has been detected. Reverse clamp connections.
