7. Do not operate charger if it has received a sharp blow, been dropped,or otherwise damaged in any way; take it to a qualified serviceman.

8. Do not disassemble charger; take it to a qualified serviceman when service or repair is required.
   Incorrect reassembly may result in a risk of electric shock or fire.

9. To reduce risk of electric shock, unplug the charger from outlet before attempting any maintenance or cleaning. Turning off
   controls will not reduce this risk. Clean only with slightly moist, not wet, cloth. Do not use solvents.

10. Warning – risk of explosive gases.

11. working in vicinity of a lead-acid battery is dangerous. Batteries generate explosive gases during normal battery operation. for this reason, it is of utmost importance that you follow the instructions each time you use the charger.

12. To reduce risk of battery explosion, follow these instructions and those published by the battery manufacturer and manufacturer of any equipment you intend to use in vicinity of the battery. Review cautionary marking on these products and on engine

13. PERSONAL PRECAUTIONS.

14. Someone should be within range of your voice OR close enough to come to your aid when you work near a battery.

15. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.

16. Wear complete eye protection and clothing protection. Avoid touching eyes while working near a battery.

17. If battery acid contacts or enters eye, flood eye with cold running water for at least 10 minutes and get medical attention immediately. If battery acid contacts skin or clothing, wash immediately with soap & water. If acid enters an eye, immediately flood eye with running cold water for at least 10 minutes & get medical attention immediately.

18. NEVER smoke or allow a spark or flame in vicinity of battery or engine.

19. Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark or short-circuit battery or other electrical part that may cause
    explosion.

20. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a battery. A battery can produce a short-circuit current high enough to weld a ring or the like to metal, causing a severe burn.

21. NEVER charge a frozen battery.

22. PREPARING TO CHARGE

23. If necessary to remove battery from vehicle to charge,always remove grounded terminal from battery first. Make sure all accessories in the vehicle are off, so as not to cause an arc.

24. Be sure area around battery is well ventilated while battery is being charged. Gas can be forcefully blown away by using a piece of cardboard or other non-metallic material as a fan.

25. Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes. d) Add distilled water in each cell until battery acid reaches level specified by battery manufacturer. Do not overfill. For a battery without removable cell caps, such as valve regulated lead acid batteries, carefully follow manufacturer’s recharging instructions. e) Study all battery manufacturer’s specific precautions such as removing or not removing cell caps while charging and recommended rates of charge. f) Determine voltage of battery by referring to vehicle or other user’s manual and before making the battery connections, make sure that the voltage of the battery you are going to charge matches the output voltage of the charger

26. CHARGER LOCATION.

27. Locate charger as far away from battery as DC cables permit.

28. Never place charger directly above battery being charged; gases from the battery will corrode and damage the charger.

29. Never allow battery acid to drip on charger when reading gravity or filling battery. Do not operate charger in a closed-in area or restrict ventilation in any way.

30. Do not set a battery on top of charger.
    IMPORTANT : Place charger on a hard flat surface or mount onto a vertical surface. Do not place on plastic, leather or textile
    surface.

31. DC CONNECTION PRECAUTIONS

32. Connect and disconnect DC output clips only after removing AC cord from electric outlet. Never allow clips to touch each other, however should this happen no damage will result to the charger circuit & the automatic charging programme will just reset t «start».

33. b) Attach clips to battery and chassis as indicated in 15(e), 15(f), and 16(b) through 16(d).
    NOTE : This battery charger has an automatic safety feature that will prevent it from operating if the battery has been inversely connected. Remove AC cord from electrical outlet, disconnect the battery clips, then reconnect correctly according to the instructions below.

34. FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE. A SPARK NEAR A BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF ASPARK NEAR BATTERY :

35. Position AC and DC cords so as to reduce risk of damage by hood, door or moving engine part.

36. Stay clear of fan-blades, belts, pulleys, and other parts that can cause injury to persons.

37. Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has larger diameter than NEGATIVE (NEG, N,–) post. d) Determine which post of battery is grounded (connected) to the chassis. If negative post is grounded to chassis (as in most vehicles), see (e). If positive post is grounded to the chassis, see (f). e) For negative-grounded vehicle, connect POSITIVE (RED) clip from battery charger to POSITIVE (POS, P, + ) ungrounded post of battery. Connect NEGATIVE (BLACK) clip to vehicle chassis or engine block away from battery. Do not connect clip to carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy gage metal part of the frame or engine block. f) For positive-grounded vehicle, connect NEGATIVE (BLACK) clip from battery charger to NEGATIVE (NEG. N, -) ungrounded post of battery. Connect POSITIVE (RED) clip to vehicle chassis or engine block away from battery. Do not connect clip to carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy gage metal part of the frame or engine block. g) When disconnecting charger, turn switches to off, disconnect AC cord, remove clip from vehicle chassis, and then remove clip from battery terminal. h) See operating instructions for length of charge information.

38. FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE. A SPARK NEAR THE BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK NEAR BATTERY :

39. Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has a larger diameter than NEGATIVE (NEG, N, -) post.

40. This battery charger has an automatic safety feature that will prevent it from operating if the battery has been inversely connected. The charger does not allow charge current unless a voltage of at least 0.5V is sensed.

41. Connect POSITIVE (RED) charger clip to POSITIVE (POS, P, +) post of battery. d) Connect NEGATIVE (BLACK) charger clip to NEGATIVE (NEG, N, -) battery post of the battery. e) Do not face battery when making final connection.

42. When disconnecting charger, always do so in reverse sequence of connecting procedure & break first connection while as far away from battery as practical.

43. A marine (boat) battery must be removed & charged on shore. To charge it on board requires equipment specially designed for marine use.

IMPORTANT : READ THE FOLLOWING INSTRUCTIONS BEFORE USING THE APPLIANCE.

FOR USERS IN CANADA and the UNITED STATES of AMERICA, ALSO READ THE ADDITIONAL SAFETY INSTRUCTIONS ON PAGES 3 & 4.

PREPARING TO CHARGE

• BATTERY TECHNOLOGY : This OptiMate PRO 4 DUO multi-bank battery charger is designed to charge 12V lead-acid or 12.8V / 13.2V Lithium Ferrous Phosphate (LiFePO4) batteries. LiFePO4: a commonly used acronym is LFP or the abbreviation LiFe. Advanced LFP/LiFePO4 batteries have a resettable internal overdischarge protective circuit within its battery management system (BMS), that will disconnect power internally from the positive battery terminal if the voltage has reduced below a set value (e.g. 8.2V) during discharge. This overdischarge protection may automatically reset and once again deliver power to the positive terminal if the voltage has increased above the reset voltage (e.g. 8.6V). This may occur repeatedly if the battery is discharging in a motorcycle, until the charge remaining has reduced to a level where the battery voltage is unable to rise above the reset level.
• DIFFERENT BATTERY SIZES : The ampmatic™ CHARGE program automatically determines the most efficient rate of charge current for the connected battery, according to its state of charge, state of health, and electrical storage (Ah) capacity.
• CHARGING ENVIRONMENT °t : LiFePO4 (LFP) batteries can be safely charged and used between the temperatures of 0°C/32°F and 45°C/113°F. If the battery was stored in temperatures above or below this range, before charging allow sufficient time for the battery temperature to acclimate within the safe temperature range. DO NOT CHARGE A FROZEN BATTERY! OptiMate PRO DUO will adjust charge current if the temperature measured at the battery charger is equal or below 0ºC / 32ºF or above 45ºC / 113ºF. If the temperature was initially below 0ºC / 32ºF charge current is limited for the first hour after which the battery is expected to have increased its internal temperature. If the temperature is below -20ºC/-4°F or above 55°C/131°F no charging will be allowed.
• Lead-acid (Pb) batteries : The charge voltage is inversely regulated according to ambient temperature i.e. voltage is increased at lower temperature, decreased at higher temperature. Adjustment: -0.004V / cell / °C above or below 20°C (68°F).
• NEW BATTERIES : Always charge before first use. New LFP/LiFePO4 batteries are subject to international transportation limitations and may be delivered with a 30% or less state of charge. Batteries fitted with resettable overdischarge protection may be delivered in ‘sleep mode’ i.e. power to the positive terminal has been internally disconnected i.e. no voltage will be measured at the battery terminals/posts. During storage the battery may have lost further charge.
• VERY FLAT NEGLECTED BATTERIES : A LiFePO4 battery left deep-discharged for an extended period may develop permanent damage in one or more cells that may heat up excessively during charging. The OptiMate PRO DUO limits charge current if the voltage is below nominal (12V / 12.8V) and the program should detect obvious cell damage and will automatically suspend charging, but it still remains essential to 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

CONNECTING TO THE BATTERY

1. Before connecting the charger to the battery always physically inspect the battery, even if new.
   WARNING – A damaged battery can overheat and emit explosive gases and a LFP/LiFePO4 may even self-combust during charging. DO NOT CHARGE THE BATTERY if you observe any of the following: case deformation such as bulging, cracks or stress fractures, loose battery terminals/posts, or leaking of any kind. Leaking confirms there is a fatally damaged cell that has burst. The liquid electrolyte is highly flammable and corrosive and a known carcinogen. Make sure the positive and negative terminals do not come into contact with each other. Shorting the positive and negative terminals may cause the battery to vent gas at a very high temperature (known as thermal runaway). Venting high temperature gas will cause irreparable damage to the motorcycle and / or serious personal injury or death. If the battery is in use or being recharged and it gives off an odour, generates heat, becomes deformed, discoloured or appears abnormal in any way, immediately discontinue use or disconnect it from the charger.

2. Before making or breaking DC/battery connections, turn off the AC supply using the ON/OFF rocker switch (SW1) located on the side of the case. (See illustration 1 on page 2).

3. When preparing a new battery prior to installation, or recharging a used battery in the designated battery preparation area, always use the fused battery clip set. First connect the red (POS / +) battery clip to the positive (POS / +) battery terminal, then connect the black (NEG / – ) battery clip to the negative (NEG / – ) battery terminal.

4. If connecting to a battery installed in a motorcycle,

5. with the provided O-14 fused battery clips: before making connections, first check that the battery clips can be safely and securely positioned clear from surrounding wiring, metal tubing or the chassis. Make connections in the following order: First connect the red (POS / +) battery clip to the positive (POS / +) battery terminal (normally not connected to the chassis), then connect the black (NEG / – ) battery clip to the negative (NEG / – ) battery terminal or to the chassis well away from the battery and fuel line. Always disconnect in reverse sequence.

6. through a pre-installed O-01 battery fused lead or other suitable power connector: before connection inspect the connector, cables to the battery and connection at the battery.

PROCEEDING TO CHARGE

1. SELECTABLE MODES:
   Pb – LED #1a – for 12V lead-acid (STD / AGM / GEL) batteries. LFP – LED #1b – for 12.8V / 13.2V LiFePO4 batteries. 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

3. 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.

4. 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.

5. 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 LiFePO4 battery delivered in ‘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.

6. If no battery has been sensed or MANUAL ACTIVATION was not successful the charger will reset after 5 minutes. Return to a) above.

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 LiFePO4 batteries with integrated battery management system (BMS) that protect against deep discharge, or for a new LiFePO4 battery delivered in ‘sleep mode’: 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.
2. 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 hold finger on selection button for 10 or more seconds until LED #3 turns full on. The program now continues directly to STEP 4. Remove finger from push button

Battery State of charge & ambient temperature
Battery voltage is measured to determine State Of Charge (SOC) and the initial charge step. LFP mode: The charge program limits charge current if the temperature measured at the OptiMate is equal or below 0ºC / 32ºF or above 45ºC / 113ºF. If the temperature was initially below 0ºC / 32ºF charge current is limited for the first hour after which the battery is expected to have increased its internal temperature. Pb and LFP charge modes: If the temperature is below -20ºC/-4°F or above 55°C/131°F no charging will be allowed. Follow instructions under section ‘LED #8 blinking rapidly – ERROR!’.

LOW VOLT SAVE MODE

Pb / LFP selection – Charging starts here for a battery with voltage measuring less than 12.4V if a Pb / lead-acid battery or 13V if a LiFePO4 battery, or if the charger was manually activated. Charging will continue through steps 4 to 6, during which continuous battery health testing is performed to ensure the battery is safely recovering. If a problem is detected charging may be suspended and LED #8 will blink rapidly. Follow instructions under section ‘LED #8 blinking rapidly – ERROR!’.

1. SAVE, deep discharged battery below 8.8V. SOC<0%

Pb : Current starts at 200mA and delivered in pulses to determine if the sulphated battery is able accept charge. Once confirmed charging will continue to STEP 5.

LFP : Current starts at 200mA and will increase as the voltage rises towards 8.8V. A healthy battery should progress to STEP 5 within 2 hours.

2. STEP- SAVE, discharged battery 8.8V or higher, able to accept charge. SOC≥0%

Pb : Current is varied between 0.2A and 1.25A, up to a voltage of 14.4V, for a maximum period of 2 hours.

LFP : Maximum current is set to 1.25A. The battery’s charge acceptance is monitored for unusual behaviour such as may be displayed by a battery with a short circuited cell.

3. STEP – TESTING – The battery’s ability to accept charge normally is monitored through-out STEP 4 and 5. A final test may be performed as described below. If damage has been detected, charging will be suspended.

Pb : A healthy Pb battery should progress to STEP 7 within two hours, otherwise charging is interrupted for 2 minutes and the battery’s ability to hold charge is monitored.

LFP : Once the voltage has risen to 13.1V charging is interrupted and the battery’s ability to hold charge is monitored for 2 minutes. A healthy battery will progress to

4. STEP

NEW mode : Charging automatically progresses to STEP 7 when the battery voltage reaches 13.1V.

BULK CHARGE SOC≥50%
Charging starts here: 1) if 60′ selection was made, or if no selection was made prior to connecting the battery, or 2) if Pb or LFP selection was made and the connected battery measures 12.4V or higher for a Pb / lead-acid battery or 13V or higher for a LiFePO4 battery. STEP 7 – The ampmatic™ CHARGE program automatically determines the most efficient rate of charge current for the connected battery, according to its state of charge, state of health, and electrical storage (Ah) capacity. The delivered current may be anywhere from 1.25A to 5A (within the safe ambient temperature environment). LED #5 – ABSORPTION CHARGE SOC≥75% STEP 8 – Charging continues until 14.4V is reached after which the ampmatic™ current control program delivers pulses of current for a period of 10 minutes, with voltage cycling between 14.1V and 14.4V to equalise the individual cells within the battery.

NOTE : For safety reasons there is an overall charge time limit of 24 hours up to STEP 8, if exceeded, STEP 9 starts automatically. 60′ mode: Charge time limit is shortened to 60 minutes; STEP 9 starts automatically after the battery ha received 1 hour of charge.

LED #6 flashing – VOLTAGE RETENTION TEST

IMPORTANT – STD (wet-cell) batteries hold a lower open circuit voltage than AGM/VRLA batteries

NOTES : A battery charged in high ambient temperature environment (30-45°C/86-113°F), or a battery recovered from a deep discharged state may need longer to cool/settle to better reflect its true state of charge (SOC%). A battery charged and tested below 0°C/32°F or above 45°C/113°F may not have received a complete charge, resulting in a lower State Of Charge result

ERROR! LED #8 blinking rapidly – ERROR

Charging has been suspended:

1. if the ambient temperature is below -20°C/-4°F or above 55°C / 131°F, indicated by the selected mode LED (Pb / LFP) blinking together with LED #8. Corrective action: When the temperature is back within range the selected mode LED will stop blinking an turn full on. Press and release the pushbutton to cancel the error (LED #8) for charging to continue.
2. during SAVE mode or the Voltage Retention Test. The battery may have suffered fatal damage and may be unserviceable. Corrective action: Thoroughly inspect the battery; refer to Section A. Preparing to charge, Very flat neglected batteries. If damage is suspected, disconnect the battery and do not charge further. Otherwise, press and release the pushbutton to cancel the error (LED #8) for charging to continue. IMPORTANT: If the Error repeats, DO NOT CHARGE AGAIN

FINAL CHARGE
The ampmatic™ current control program now delivers pulses of current up to a voltage of 14.4V, to equalise the individual cells within the battery and optimizes charge level. Charge time is 2h / 120 minutes. the MAINTENANCE CHARGE CYCLE consists of 30 minute charge periods followed by and alternating with a 30 minute ‘rest’ periods, during which there is no charge current. During the 30 minute charge cycles current is delivered only if the battery has lost charge as compared to the TEST result in STEP 9. 60′ mode: For a healthy battery the program progresses from STEP 9 directly to STEP 11.
