4. When the battery closes to full charge and goes into the completion phase, the
CHARGED LED will on, and the CHARGING LED will be flashing. At this
moment, the battery can be used immediately. To reach a 100% state of charge,
the charger must stay connected until it enters the rest phase when only the
green CHARGED is lit solid.
5. When the charging process is finished, disconnect AC power, then disconnect
DC leads from battery correctly.
H FEATURES
Multi-Stage Charging Process
The charger uses a multi-stage charging process designed to charge and maintain
the battery. The charging process includes a Soft Start mode to charge deeply
discharged batteries properly and is beneficial for a battery’s long-term health. The
last procedure in the charging routine is a Maintenance Mode that allows the
charger to be connected to a battery and maintain a proper charge level.
Smart Clamp Technology
The charger will supply power to the output leads only when a correct connection
is made.
Multiple Battery Compatibility
The charger will charge different battery types, including conventional, maintenance
free, AGM gel cell, LiFePO4 and deep cycle batteries.
Multiple Output Options
The charger comes complete with DC output clamps, ring terminals and 12V
adapters to charge or maintain the battery.
Reverse Polarity Protection
Reverse Polarity LED will flash, and power will be cut off if the clamps connect
reversely.
Battery Fault Protection
Conditions that cause the fault include connecting to a battery with a voltage less
than 1V, connecting to a battery with a voltage above 16V in 12V mode (8V in 6V
mode), connecting to a battery with a shorted cell or if the charger diagnoses an
incorrect voltage selection.
Recovery Mode
The charger can protect the interruption of power (power outage). When a power
interruption occurs, all LEDs will turn off, except the Battery Type LED, which will
blink slowly. After 36 hours, to conserve the charge on the connected battery, all
LEDs will turn off. Upon resumption of power, the charger will resume regular
operation in the existing settings and status indicators will again be active. For a
limited time after the resumption of power, the CHARGED LED will blink to indicate
that Recovery Mode had been activated. If the battery’s voltage is too low (<6V) to
support Recovery Mode, while charging, the Battery Type LED will flash rapidly to
alert the user for this condition. Once the battery’s voltage increases above 6V,
Recovery Mode will again be supported, and the Battery Type LED will stop flashing.
I REGULAR MAINTENANCE
Read and follow the manual. Please clean the case and all the accessories for the
charger frequently or after every use. Do not expose the charger to rain or snow.
