4. 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.
5. WARNING - RISK OF EXPLOSIVE GASES.
   a) WORKING IN VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. B ATTERIES 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.
   b) 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.

11. PERSONAL PRECAUTIONS.

a) Someone should be within range of your voice OR close enough to come to your aid when you work near a battery.
b) Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.
c) Wear complete eye protection and clothing protection. Avoid touching eyes while working near a battery.
d) 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.
e) NEVER smoke or allow a spark or flame in vicinity of battery or engine.
f) 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.
g) 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.
i) NEVER charge a frozen battery.

12. PREPARING TO CHARGE

a) 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.
b) 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.
c) Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
d) Study all battery manufacturer's specific precautions such as removing or not removing cell caps while charging and recommended rates of charge.
e) 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.

13. CHARGER LOCATION.

a) Locate charger as far away from battery as DC cables permit.
b) Never place charger directly above battery being charged; gases from battery will corrode and damage the charger. c) 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.
d) 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.

14. DC CONNECTION PRECAUTIONS

a) Connect and disconnect DC output clips only after setting any charger switches to off position and 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 to «start».

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. Set charger switches to off position and/or remove AC cord from electrical outlet, disconnect the battery clips, then reconnect correctly according to the instructions below.

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

a) Position AC and DC cords so as to reduce risk of damage by hood, door or moving engine part.
b) Stay clear of fan -blades, belts,pulleys,and other parts that can cause injury to persons.
c) 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.

16. 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 :

a) Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has a larger diameter than NEGATIVE (NEG,N, -) post.
b) This battery charger has an automatic safety feature that will prevent it from operating if the battery has been inversely connected. The charger does allow charge current unless a voltage of at least 0.5V is sensed.
c) 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.
f) When disconnecting charger, always do so in reverse sequence of connecting procedure & break first connection while as far away from battery as practical.
g) A marine (boat) battery must be removed & charged on shore. To charge it on board requires equipment specially designed for marine use.

AUTOMATIC DIAGNOSTIC CHARGER FOR 12.8V LiFePO _4 (LITHIUM IRON PHOSPHATE) BATTERIES FROM 2.5Ah TO 30Ah:

SAFETY WARNING AND NOTES: IF YOU HAVE NOT YET DONE SO, READ THE PRECEDING PAGES LABELLED "IMPORTANT SAFETY INSTRUCTIONS" BEFORE OPERATING THIS CHARGER.

This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.

USING THE OPTIMATE LITHIUM 0.8A

CORRECT USE: Use the charger only if the input and output leads and connectors are in good, undamaged condition. If the input cable is damaged, it is essential to have it replaced without delay by the manufacturer, his authorised service agent or a qualified workshop, to avoid danger. Protect your charger from damp and humid conditions both during use and in storage. Damage resulting from corrosion, oxidation or internal electrical short-circuiting is not covered by warranty. Distance the charger from the battery during charging to avoid contamination by or exposure to acid or acidic vapours. If using it in the horizontal orientation, place the charger on a hard, flat surface, but NOT on plastic, textile or leather. Use the fixing holes provided in the enclosure base to attach the charger to any convenient, sound vertical surface.

EXPOSURE TO LIQUIDS: This charger is designed to withstand exposure to liquids accidentally spilled or splashed onto the casing from above, or to light rainfall. Prolonged exposure to falling rain is inadvisable and longer service life will be obtained by minimizing such exposure. Failure of the charger due to oxidation resulting from the eventual penetration of liquid into the electronic components, connectors or plugs, is not covered by warranty.

CHARGING TIME

Charge time on a flat but otherwise undamaged battery:

For batteries rated from 2.5Ah to 5Ah: 180 to 360 minutes to progress to the voltage retention test.

For batteries rated above 5Ah: 125% of the battery's Ah rating, so a 30Ah battery should take no more than about 38 hours to progress to the voltage retention test.

Deep-discharged batteries may take significantly longer. A full charge may not be achieved within the 24 hour charge safety limit. In this case follow the reset procedure below.

ECO POWER SAVING MODE WHEN THE CHARGER IS CONNECTED TO AC SUPPLY:

The power converter switches to ECO mode when the charger is not connected to a battery resulting in a very low power draw of less than 0.5W (per charging bank), equivalent to power consumption of 0.012 kWh per day. When a battery is connected to the charger power consumption depends on the current demand of the battery and its connected vehicle / electronic circuitry. After the battery has been charged and the charger is in long term maintenance charge mode (to keep the battery at 100% charge) the total power consumption is estimated to be 0.024 kWh or less per day.

CONNECTING THE CHARGER TO THE BATTERY

1. Disconnect AC power supply before making or breaking DC / battery connections.
2. If charging a battery in the vehicle with the 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 to the battery terminal not connected to the chassis (normally positive), then connect the other battery clip (normally negative) to the chassis well away from the battery and fuel line. Always disconnect in reverse sequence.

1. When charging a battery out of the vehicle with the battery clips, place it in a well ventilated area. Connect the charger to the battery: RED clamp to POSITIVE (POS, P or +) terminal and BLACK clamp to NEGATIVE (NEG, N or -) terminal. Make sure the connections are firm and secure. Good contact is important.

PROCEEDING TO CHARGE

The LED indicators below are sequenced as they may come on through the course of the program.

1 2 6 5 12.8V 1 2 3 4 LiFePO₄ Bms 3 4 24-724-7

LED #1 : POWER ON - Confirms AC power supply to the charger.

HIGH and LOW intensity indication:-LOW: No battery connected. HIGH: battery connected and current is being delivered.

LED #2 : REVERSE POLARITY PROTECTION - 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.

BMS RESET PROCEDURE: for batteries with a built-in battery management system (BMS) that protects against deep discharge, follow this procedure: 1) Disconnect OptiMate Lithium from mains supply. Wait for LED #1 to go out. 2) Connect OptiMate Lithium to the battery: RED clamp to POSITIVE (POS, P or +) terminal and BLACK clamp to NEGATIVE (NEG, N or −) terminal. 3) Reconnect the OptiMate Lithium to mains supply.

A special BMS reset pulse is delivered for a period of one minute. LED #3 flashes as each reset pulse is delivered.

The BMS has successfully reset when either LED #3 OR LED #4 lights by itself.

BMS not resetting: 1) An advanced battery management system that includes thermal protection, prevents operation if the battery temperature falls outside of the manufacturer recommended safe operating temperature range. Check battery manufacturer's specifications. 2) Battery is connected in reverse polarity. Correct the connections and try again. 3) The circuit connected to the battery is preventing the pulse from being delivered. Disconnect or turn off the circuit and try again. 4) The battery's BMS may have suffered damage. Have the battery professionally assessed.

LED #3 SAVE : This mode engages if the battery was more than 90% discharged / voltage is below 12.8V. During the SAVE mode the program limits charge current and tests for cell damage. Charge current is automatically adjusted as charging progresses. A healthy LiFePO4 battery will progress to CHARGE mode within 4 hours.

ERROR: TEST LED #6 flashing - Charging has been suspended as OptiMate has detected the battery may have suffered permanent damage and a professional assessment is required.

CAUTION: A deep discharged LiFePO _4 battery may have developed permanent damage in one or more cells. Higher capacity batteries with multiple cells in parallel (4s2p or more configuration) may have a good cell paired with bad cell, if so, it will take longer to detect the bad cell. Such a battery may heat up excessively during charging, confirming there is

a problem within the battery. 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.

CHARGE LED #4 - CHARGE, PULSE ABSORPTION & CHARGE VERIFICATION steps: A constant current of 0.8 Amps is delivered into the battery, up to a voltage of 14.3V. Battery charge level is verified. If the battery requires further charging-variable current pulses are delivered to the battery, bringing each cell to equal and full charge.

NOTE: For safety reasons there is an overall charge time limit of 48 hours.

LED #5: BATTERY READY / 24-7 Maintenance active:

The battery can be used. If left connected (recommended), battery health is confirmed, followed by the OptiMate 24-7 maintenance that maintains the battery at full charge.

5.1 Health test starts immediately after LED #5 lights. Delivery of current to the battery is interrupted for up to 12** hours to allow the battery to settle and confirm that the vehicle circuitry is not depleting the battery. See page 2 for LED 5 & 6 corresponding to charge level / battery health. LED #6 lights if battery is being depleted or health is not optimal.

** If charge delivery was less than 12h up to when LED #5 turned on, health test extends until 24h has elapsed, followed by 24-7 maintenance.

5.2 OptiMate 24-7 maintenance: During every hour that the battery remains connected OptiMate's 24-7 maintenance program delivers up to 30 minutes of float charge maintenance at a voltage of 13.6V, followed and alternating with 30 minute REST (no charging) periods. Charge level is continuously monitored. OptiMate Lithium will counter discharge by connected circuitry or battery self-discharge. TIP: At least once every two weeks, check battery status.

IMPORTANT: When handling batteries or in their vicinity, always take care to observe the SAFETY WARNINGS above.

1. LED #6 flashing / blinking - BATTERY is not holding charge / charging suspended.

The battery's voltage is not being sustained above 12V or could not be sufficiently recovered. In the case of a battery still connected to the electrical system it supports, the red LED #6 may be signalling a loss of current through connected wiring or 'always on' current-consuming accessories. A sudden load such as vehicle headlights being switched on or engine started while the charger is connected can also cause the battery voltage to dip significantly.

To rectify: disconnect OptiMate Lithium, allow program to reset and then reconnect.
