1. SELECTABLE MODES:
Pb - LED #1a - for 12V lead-acid (STD / AGM / GEL) batteries.
LFP - LED #1b - for 12.8V / 13.2V LiFePO
60' - LED #2 - A shortened program with charge time limited to 60 minutes or 1 hour, suitable for first charge /
activation of a new battery, or a quick recharge of a healthy used battery with voltage higher than 11.4V. NOTE:
If no selection (Pb or LFP) is made prior to connecting a battery for charge, the 60' mode becomes the default
selection.
WARNING: Select the correct charge mode for deep discharged Pb / lead-acid or LFP / LiFePO4 batteries
or LFP / LiFePO4 batteries that require BMS reset.
2. START - CHARGE A BATTERY
a) Connect the battery as described in section B. CONNECTING TO THE BATTERY.
WARNING: If LED #1a and 1b are blinking together the battery is connected in reverse polarity. Correct the
connection to continue.
b) The Pb (LED #1a), LFP (LED #1b) and 60' (LED #2) selection indicators will be (dimly) lit.
To make a charge mode selection press and release the button once for Pb, twice for LFP or three times for 60'.
Continuing to press and release the button in rapid succession will cycle selection from Pb through to 60' and
then back to Pb. If no further selection is made for 3 seconds the last selected mode LED brightens to confirm
selection is now final.
NOTE: If no selection is made 60sec. following connecting a battery for charge, the 60' mode activates
automatically. To change selection, disconnect the battery, wait for the program to reset (confirmed when all
LEDs flash together twice) and then return to a). Alternatively, turn off AC SW1 to reset all charge banks /
stations.
c) The OptiMate now determines the battery voltage.
Pb & LFP modes: if the connected battery's voltage is 0.5V or higher charging continues automatically, see
STEP 1 - AUTOMATIC ACTIVATION.
60' mode: charging continues only if the battery voltage is higher than 11.4V, See STEP 1 AUTOMATIC
ACTIVATION.
LFP mode: If the connected battery measures less than 0.5V, as expected for a deep discharged LiFePO4
battery with battery management system (BMS) that requires a reset, or for a new LiFePO
'sleep mode' (read prior section NEW BATTERIES), follow the procedure described under MANUAL ACTIVATION
(STEP 1).
NOTE: If Pb was selected, no further charging is possible. If a lead-acid battery could not recover to at least 0.5V
when disconnected from vehicle circuitry, it is unlikely the battery will be successfully returned to service.
d) If no battery has been sensed or MANUAL ACTIVATION was not successful the charger will reset after 5
minutes. Return to a) above.
STEP 1 - Charger activation
AUTOMATIC ACTIVATION: The program proceeds directly to STEP 2 & 3 and LED #3 or LED #4 will turn on
depending on condition of the battery and selected mode.
MANUAL ACTIVATION: Required for LiFePO
protect against deep discharge, or for a new LiFePO
Press the pushbutton until LED #3 starts blinking. Remove finger from pushbutton.
LED #3 now blinks once per second as a special BMS reset pulse is delivered.When the OptiMate 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.
BMS not resetting: LED #3 stopped blinking after one minute and turned off and LED #8 may now be blinking
indicating a possible ERROR. See list below, each with a suggested corrective action. Correct the error, press
and release the button to cancel the ERROR indication and then re-attempt MANUAL ACTIVATION.
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) Temperature as measured at the battery charger is below -20ºC/-4°F or above
55°C/131°F. Follow instructions under section 'LED #8 flashing rapidly- ERROR!'. 5) A deep discharged
battery may not hold sufficient voltage to power its own BMS system. After cancelling the error, now place and
batteries.
