percentage (SOC%). Immediately following charging a battery may briefly hold a higher voltage, as charging
raises the temperature of chemical elements within the battery. A battery recovered from a deep discharged
state may need longer to cool and voltage to settle and reflect its true state of charge (SOC%).
1. For any test result other than green #6, disconnect the battery from the electrical system it supports, and
reconnect the OptiMate Lithium. If a better test result is now obtained, this suggests that the power losses are
partly due to an electrical problem in the electrical system and not in the battery itself.
NOTE: A sudden load being switched on while the charger is connected can cause the battery voltage to
reduce significantly and test result to worsen.
2. TEST LED #8 (red) flashing rapidly - Charging is suspended.
If it occured during -
a) a BMS reset: The battery has suffered damage (internal short circuit) or the connected circuitry is not allowing
the BMS pulse to be delivered to the battery.
b) STEP 3 - Preparing to charge - Temperature measured is below -20°C / -4°F. LiFePO4 batteries may suffer
damage if charged below this temperature.
c) STEP 4 SAVE mode: The charger has sensed that the battery is not accepting charge as expected. Try once
more and if the result repeats, do not charge again! A professional assessment is required.
d) STEP 9: STATE OF HEALTH TEST - the voltage reduced below 12.8V within the first 30 minutes, indicating
the battery cannot hold charge and may be damaged. A professional assessment is required.

MAINTAINING A LITHIUM BATTERY FOR EXTENDED PERIODS: A LiFePO battery can be left connected to the
4
OptiMate Lithium for any extended period of time. The OptiMate Lithium maintenance program is fully
automatic, it continuously monitors the battery voltage and delivers current only if it sensed the battery has lost
charge (possibly through connected vehicle or other circuitry or self discharge). The OptiMate Lithium's
maintenance program guarantees the battery will remain at or close to full charge, but never overcharged.
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, 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 0.024kWh or
less per day.
