TecMate Optimate4 Instructions For Use Manual page 8

SELECTING A CHARGE PROGRAM: OptiMate4 Quad program has four selectable charge programs. A
charge program must be selected before making connection to a battery. Each program has unique charge
and test parameters to match the battery's chemistry and connection method to the battery. The selected
program remains in memory after disconnection from the battery, or if AC power is interupted, or until a new
selection is made.
PROGRAM 1 - Pb (LED #1a) : is the direct-to-battery charge program for a lead-acid battery in any
condition. All program features are active, including high voltage TURBO and PULSE desulfation mode.
JP
PROGRAM 2 - Pb (LED #1a) + CAN-bus (LED #2): automatically activates charging for a lead-acid battery
through the 12V outlet on vehicles fitted with a CAN-bus controlled 12V outlet, to charge, test and maintain a
healthy battery when the vehicle is in storage. All desulfation modes are de-activated. The CAN-BUS (LED
#2) blinks until a battery is sensed, then it turns full on.
CN
IMPORTANT: FLAT BATTERY (< 5V) - if the vehicle's lead-acid battery is deep discharged the vehicle's
CAN-bus system will not be able to activate the 12V socket. Remove the battery, inspect it for physical
damage or leakage, if deemed acceptable, to recharge select Program 1 and connect the OptiMate4 directly
to the battery.
KR
PROGRAM 3 - LFP (LED #1b): is the direct-to-battery charge program for a LiFePO4 (Lithium Ferrous
Phosphate) battery in any condition.
Use this program to reset a battery fitted with integrated battery management system (BMS) that protect
against deep discharge.
IMPORTANT! Before proceeding, confirm the battery is connected correctly: Read the section on the
previous page: CONNECTING CHARGER TO THE BATTERY.
Press the pushbutton. After 3 seconds LED #3 lights every second as a special BMS reset pulse is
delivered. When the OptiMate 4 senses the battery BMS has reset the reset pulses will automatically
discontinue and charging will automatically continue. 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. Use the MANUAL RESET: place and hold finger on BMS
reset button for 10 or more seconds, until the program continues to STEP 4.
BMS not resetting: LED #8 flashes/blinks.
1) Battery is connected in reverse polarity. Correct the connections and try again. 2) The system
powered by the battery is preventing the pulse from being delivered. Disconnect or turn off the system
and try again. 3) The battery's BMS or the battery itself may have suffered damage. Have the battery
professionally assessed.
More: 4) An advanced battery management system may include thermal protection that prevents reset
if the battery temperature falls outside of the manufacturer recommended safe operating temperature
range. Check battery manufacturer's specifications.
PROGRAM 4 - LFP (LED #1b) + CAN-bus (LED #2): automatically activates charging through the 12V outlet
on vehicles fitted with a CAN-bus controlled 12V outlet, to charge, test and maintain a healthy LiFePO4
(Lithium Ferrous Phosphate) battery when the vehicle is in storage. The CAN-BUS (LED #2) blinks until a
battery is sensed, then it turns full on.
IMPORTANT: FLAT BATTERY (< 9V) - if the vehicle's LFP/Lithium battery is deep discharged or the battery's
BMS system has turned off power within, the vehicle's CAN-bus system will not be able to activate the 12V
socket. Remove the battery, inspect it for physical damage or leakage, if deemed acceptable, to recharge
select Program 3 and connect the OptiMate4 directly to the battery.
VERY FLAT NEGLECTED BATTERIES: If the battery is deeply discharged (and possibly sulfated),
remove from the vehicle or equipment and inspect the battery before connecting the charger for a
recovery attempt. ATTENTION: A battery left deep-discharged for an extended period may develop
permanent damage in one or more cells. Such batteries may heat up excessively during high current
charging. Monitor the battery temperature during the first hour, then hourly there-after. Check for
unusual signs, such as bubbling or leaking electrolyte, heightened activity in one cell compared to
