battery
left deep-discharged for an extended period may develop permanent damage in one or more cells. Such
batteries may heat up excessively during charging.
During the SAVE mode the program limits charge current
if the voltage is below nomimal (12.8V / 16V) and the program should detect obvious cell damage and will
automatically suspend charging, but the higher the cell count in parallel the more difficult it is to detect a bad
cell.
ALWAYS monitor the battery temperature during the first hour, then hourly there-after. If at any time
the battery is uncomfortably hot to touch or you notice any unusual signs, DISCONNECT THE CHARGER
IMMEDIATELY.

MANUAL CHARGE
ACTIVATION:
WARNING:
Prior to and
following MANUAL
CHARGE ACTIVATION
monitor the battery
temperature. If at any
time the battery is
uncomfortably hot to
touch or you notice
any unusual signs,
DISCONNECT THE
CHARGER
IMMEDIATELY.
LED #1a & LED #1b:
Confirms AC power supply to the charger and
selected battery voltage.
Changing voltage selection:
Disconnect charger from battery. Push
and release the SELECT pushbutton. The mode selection changes
when the button is released. SAVE (#3), CHARGE (#4) and TEST (#6,7,
8) LEDs flash twice to confirm selection is in memory.
LED #1a => 12.8V LED #1b => 16V
NOTE: Selection remains even if AC power is lost.
LED #2 REVERSE POLARITY:
Lights when the battery connections
are incorrect.
The charger is electronically protected so no damage
will result, and the output will remain disabled until the connections
are corrected.
AUTOMATIC ACTIVATION:
The CHARGE mode automatically activates
and LED #1a brightens if the connected battery voltage is at least 0.5
Volt. The program proceeds directly to STEP 2 & 3.
MANUAL ACTIVATION:
may be required for batteries with integrated
battery management system (BMS) that protects against deep
discharge.
Press the pushbutton.
LED #3 blinks once per second as a special
BMS reset pulse is delivered. When the OptiMate Lithium senses the
battery BMS has reset, LED #3 turns full on, the reset pulses will
automatically discontinue and the program will continue to STEP 5.
Remove finger from pushbutton.
BMS not resetting / LED #3 lights briefly and then turns off:
A deep
discharged battery may not hold sufficient voltage to power its own
BMS system.
MANUAL CHARGE ACTIVATION:
Place and hold finger on BMS reset
button for 10 or more seconds until LED #3 turns full on. The charge
program now automatically starts at STEP 4 or 5.
ERROR! LED #8 flashes/blinks:
1) Battery is connected in reverse
polarity. Correct the connections and try again. 2) The vehicle
circuitry powered by the battery is preventing the pulse from being
delivered. Disconnect the battery from the vehicle and try again. 3)
The battery's BMS or the battery itself may have suffered damage.
Have the battery professionally assessed. 4) The charger cannot
deliver current as the ambient temperature may be out of safe
charging range for the battery. See page 2 for temperature (°C/°F)
and corresponding Ampére (A) values.
