VERIFICATION: The circuit verifies battery charge level.
If the battery requires further charging the programme reverts to BULK CHARGE for brief periods, delivering a variable current pulse to the
battery. These reversions may occur as many times as is necessary to reduce the battery's current demand below 200mA at 13.6V (which is
consistent with a battery that has accepted as much charge as its basic condition allows). (see expected Charging time.)
NOTE: For safety reasons there is an overall charge time limit of 48 hours.
VOLTAGE RETENTION TEST: LED #5 flashing
Delivery of current to the battery is interrupted for 12 hours* to allow the program to determine the battery's ability to retain charge. For batteries
with a good state of health LED #5 (green) should continue to flash for the full 12 hours* period. Read the section NOTES ON TEST RESULTS on
reasons for poor test results or how to test a battery that returns a good result but cannot deliver sufficient power once it is returned to service.
MAINTENANCE CHARGE: LED #5 / 6 steady on
For 30 minutes the circuit offers current to the battery within a safe 13.6V voltage limit whilst the result of the voltage retention test is
displayed. If LED #6 (red) indicated the VOLTAGE RETENTION TEST will be repeated. A steady LED #5 (green) indicate the 30 minute float
charge maintenance periods follow and alternate wih the 30 minute REST (no charging) periods until the battery is disconnected. The battery
can draw current as required to support small loads and counter self-discharge.
NOTES ON TEST RESULTS:
1. For any test result other than green #5, 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. If the poor result persists, you are advised to take the battery to a professional service workshop equipped with
professional equipment for a more thorough investigation.
2. If the red LED #6 alone, or the GREEN #5 and red LED #6 indicate together, a significant problem exists. The green + red LEDs mean that
after being charged the battery's voltage is not being sustained or that despite recovery attempts the battery was irrecoverable. This may be
due to a defect in the battery itself, such as a short-circuited cell, or, 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 deteriorated wiring or a degraded switch or contact, or in-circuit
current-consuming accessories. A sudden load being switched on while the charger is connected can also cause the battery voltage to dip
significantly. Follow the recommendations outlined in point 1.
AUTOMATIC BATTERY MAINTENANCE:
The MAINTENANCE CHARGE CYCLE consists of 30 minute charge periods followed by
and alternating with a 30 minute 'rest' periods, during which there is no charge current. The circuit offers current to the battery within a safe
13.6V voltage limit ("float charge"), allowing it to draw whatever small current is necessary to sustain it at full charge and compensate for
any small electrical loads imposed by connected circuitry, or the natural gradual self-discharge of the battery itself.
The BATTERY REFRESH CYCLE is performed if the charger detects the battery has lost charge. The program returns to OPTIMIZE mode (LED
#4) and then proceeds to the voltage retention test and maintenance charge cycle.
