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 LiFePO 4
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
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 may have developed permanent damage
