Maintain
For batteries with a
good state of health LED
#6 (green) will remain
on.
Exception: STD wet cell
batteries with filler caps
have a lower fully
charged voltage: LED
#6 remains on together
with LED #7.
VERY FLAT NEGLECTED BATTERIES: If the battery is deeply discharged (and possibly sulfated),
remove from the vehicle or equipment and inspect the battery before connecting the charger for a
recovery attempt.
The charger's TURBO recovery mode cannot engage if it senses that the battery is still connected to a
circuit which effectively offers a lower electrical resistance than the battery on its own. However, if the
deep-discharged battery is not removed for recovery, neither battery nor vehicle or equipment electronics
will be damaged. Pay particularly close attention to the following A battery left deep-discharged for an
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:
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.

TEST after charge : Delivery of current to the battery is
interrupted for 30 minutes** to allow the program to
determine the battery's ability to retain charge.
** IF charging started in SAVE mode (LED #3) the voltage
retention test is extended to 12 hours to confirm battery health.

8 LED #6 (green) will remain on for batteries able to hold 90% or
higher state of charge (SOC%), otherwise the TEST result is
adjusted lower in real time according to the measured battery
voltage. Consult the table on page 2 to match TEST LED indication
to an estimated state of charge percentage (SOC%).
Also read section "NOTES ON TEST RESULTS" below.
MAINTENANCE CHARGE: LED #6 / 7 / 8 steady on
according to state of charge measured during STEP 8.
Float voltage setting: 13.6V nominal at 20°C (68°F) The float
voltage is inversely regulated according to ambient
6
temperature; i.e., voltage is increased at lower temperature,
7
8
decreased at higher temperature.
Adjustment: -0.004V / cell / °C above or below 20°C (68°F).
OptiMate 24-7 maintenance mode consists of 30 minute float
24-7
charge periods followed by and alternating with 30 minute 'rest'
periods, during which there is no charge delivered. This "50% duty
cycle" prevents loss of electrolyte in sealed batteries and
minimizes gradual loss of water from the electrolyte in batteries
with filler caps, optimizing the service life of irregularly or
seasonally used batteries.
During "float charge" a continuous LOW CURRENT PULSE IS
DELIVERED TO PREVENT SULFATION, further extending battery
power and life.
If the OptiMate senses the battery has suddenly lost charge
the program will revert back to STEP 7.
