extended period may develop permanent damage in one or more cells. Such batteries may heat up
excessively during high current charging. Monitor the battery temperature during the first hour, then hourly
there-after. Check for unusual signs, such as bubbling or leaking electrolyte, heightened activity in one cell
compared to others, or hissing sounds. If at any time the battery is uncomfortably hot to touch or you notice
any unusual signs, DISCONNECT THE CHARGER IMMEDIATELY.
MAINTAINING A BATTERY FOR EXTENDED PERIODS:
For accurate temperature regulated charging and
long term maintenance place OptiMate as close as possible to the battery under charge. For example, if the
battery is within a vehicle or craft stored outside in direct sun or cold, place the OptiMate inside the vehicle or craft
(or its battery compartment) so that charge voltage can be adjusted according to the same environment
temperature that the battery would experience.
The OptiMate will maintain a battery whos basic condition is good, for months at a time. At least once every
two weeks, check that the connections between the charger and battery are secure, and, in the case of
batteries with filler caps on each cell, disconnect the battery from the charger, check the level of the
electrolyte and if necessary, top up the cells (with distilled water, NOT acid), then reconnect. When handling
batteries or in their vicinity, always take care to observe the SAFETY WARNINGS above.
NOTES ON TEST RESULTS: The voltage of a cooled battery is directly proportional to its State Of Charge
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 (or green #6 and yellow #7 together if the battery is a STD type
with filler caps), disconnect the battery from the electrical system it supports, and reconnect the OptiMate. 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.
2. If the red LED #8 alone, or the yellow #7 & red LED #8 indicate together, or yellow #7 LED alone for a
sealed battery, a significant problem exists. The battery is unable to retain sufficient charge or is losing
charge very fast due to connected circuitry. A sudden load being switched on while the charger is connected
can also cause the battery voltage to dip significantly.
3. GOOD TEST RESULT, but the battery cannot deliver sufficient power: Degraded inter-cell connections or
poor external connection at battery posts may cause severe voltage drop when high current is demanded
from the battery. Check external battery connections or have battery professionally assessed (load tested).
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.
