others, or hissing sounds. If at any time the battery is uncomfortably hot to touch or you notice any
unusual signs, DISCONNECT THE CHARGER IMMEDIATELY.
CHARGING TIME : Charge time on a flat but otherwise undamaged battery: a 12Ah battery should take no
more than about 12 hours to progress to the self-discharge check. Deep-discharged batteries may take
significantly longer.
MAINTAINING A BATTERY FOR EXTENDED PERIODS: OptiMate 4 Quad Program is designed to maintain a
battery continuously (24-7); it can be safely left connected to a healthy battery for months at a time.
RECOMMENDED: At least once every two weeks, check that the connections between the charger and
battery are secure. In the case of lead-acid batteries with filler caps on each cell, disconnect the battery from
the charger, check the level of the electrolyte and if necessary, top up the cells (with distilled water, NOT
acid), then reconnect. When handling batteries or in their vicinity, always take care to observe the SAFETY
WARNINGS above.

STEP 3 Immediately following connection to a battery there may be a 1-2 second delay
before charging progresses, during which time battery State Of Charge is measured to
PRE-TEST
determine charge requirement and duration of the State Of Health test in STEP 8.
Changing selection: Disconnect OptiMate4 from the battery or vehicle. Push and
release the pushbutton switch. The mode selection changes when the button is
released. Continue to press and release until the desired program has been
selected. If no futher selection is made for at least 3 seconds SAVE (#3), CHARGE
(#4), OPTIMIZE(#5) and TEST (#6,7, 8) LEDs flash twice to confirm selection is in
memory. Connect OptiMate4 to the battery or vehicle.
ATTENTION: Each program is described in detail on the preceding page.
For 12V lead-acid (Pb) batteries:
PROGRAM 1 (LED #1a) : Charge directly to battery.
PROGRAM 2 (LED #1a) + CAN-bus (LED #2): Charge via CAN-bus controlled 12V
outlet on BMW motorcycles.
For 12.8V / 13.2V lithium LFP / LiFePO
PROGRAM 3 (LED #1b) : Charge directly to battery.
PROGRAM 4 (LED #1b) + CAN-bus (LED #2): Charge via CAN-bus controlled 12V
outlet on BMW motorcycles.
Battery voltage check - OptiMate 4 automatically activates if
Programs 1 & 3 : connected battery voltage is at least 0.5 Volt.
Programs 2 & 4 : LED #2 changes state from blinking to full on, indicating the
CAN-bus controlled 12V outlet has turned on and is allowing the battery to
receive a charge.
For LiFePO4 batteries with resettable protection (BMS) - See SELECTING A
CHARGE PROGRAM > PROGRAM 3 > BMS RESET how to activate charging.
Charging proceeds directly to STEP 3.
REVERSE POLARITY PROTECTION: LED #1a / LED #1b blinks rapidly 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.
MANUAL ACTIVATION for LiFePO4 batteries with resettable protection (BMS)
- See SELECTING A CHARGE PROGRAM > PROGRAM 3 > BMS RESET how to
manually activate charging.
CAN-bus programs 2 & 4 : Not activating? Consult troubleshooting guide on
