NON-RECHARGEABLE BATTERIES.
1. GENERAL BATTERY CHARGER PRECAUTIONS.
CAUTION : DO NOT CONNECT TO GROUND. Do not expose charger to rain or snow. Use of an
attachment not recommended or sold by the battery charger manufacturer may result in a
risk of fire, electric shock, or injury to persons. To reduce risk of damage to electric plug and
cord/cable, pull by plug rather than cord/cable when disconnecting charger. Do not operate
charger with damaged cord or plug - If the cable is damaged, it is essential to have it replaced
without delay by the manufacturer, an authorised service agent or a qualified workshop, to
avoid danger. Do not operate charger if it has received a sharp blow, been dropped, or has
been otherwise damaged in any way; take it to a qualified Service Technician. 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. Before attempting any
maintenance or cleaning, to reduce risk of electric shock, unplug the charger from the AC
outlet and the battery. Clean only with slightly moist, not wet, cloth. Do not use solvents.
2. AC EXTENSION CORDS/CABLES.
An extension cord/cable should not be used unless absolutely necessary. Use of improper
extension cord could result in a risk of fire and electric shock. If extension cord must be used
make sure that : a) pins on plug of extension cord are the same number, size and shape as
those of plug on charger, b) the extension cord is properly wired and in good electrical
condition, and c) the conductor wire size is large enough for the AC ampere rating of the

USING THE OPTIMATE LITHIUM:
CONNECTION ACCESSORIES
Two interchangeable connection sets are supplied with the battery charger:
1) A battery lead with metal eyelet lugs for permanent fitment to the battery posts, and
re-sealable weatherproof cap on the on the connector that connects to the charger output
cable. Consult a professional service agent for assistance in attaching the metal eyelets to
the battery posts. Secure the connector with weatherproof cap so that it cannot foul any
moving part of the vehicle or the cable can be pinched or damaged by sharp edges.
IMPORTANT: This battery lead is protected by a 15A fuse. If under any circumstance the fuse
blows, do not try and replace the fuse without first identifying and correcting the issue that
caused the fuse to blow. Only replace the fuse with a 15A rated ATO fuse.
2) A set of battery clips for charging the battery on or off-vehicle. Read IMPORTANT SAFETY
INSTRUCTIONS points 8 or 9 before connecting to the battery.
OPTIONAL BATTERY CONNECTION: On some vehicles it is possible to charge the battery
through the fitted auxiliary 12V DIN/ISO 4165 power socket. The battery can only be charged
and maintained if the 12V socket remains powered up after the ignition has been turned off
and the vehicle has been parked. Find a suitable accessory at www.optimate1.com.
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 10Ah battery should
take no more than about 12.5 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.
PROCEEDING TO CHARGE
The LED indicators below are sequenced as they may come on through the course of the program.
NOTE: Charge stations / banks on OptiMate Lithium 4s0.8A x4 operate independently.
LED #1 : POWER ON -Confirms AC power supply to the charger.

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 a multi-bank / station TM-484 / TM-485, BMS pulses are
automatically & continuously delivered if no battery voltage is sensed. After connection to the
battery the BMS has successfully reset when either LED #3 OR LED #4 lights by itself.
For a single bank / station TM-47x, TM-497 charger, 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 vehicle or equipment 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 LiFePO4battery may have developed permanent damage
in one or more cells. Higher capacity batteries with multiple cells in parallel (4s2p or more
configeration) 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:
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 wih 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.
6. 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.
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.
