5. 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.

* If charge delivery was less than 12 hours, test extends until 24 hours has elapsed.

6. 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.

Maintaining a battery for extended periods: 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.

Charging time: The time required for the OptiMate 3 to complete a charge on a flat but otherwise undamaged battery is roughly equal

to the battery’s Ah rating, so a 10Ah battery should take no more than about 10 hours to progress to Step 4. Deep-discharged batteries may

take significantly longer.

Notes on TEST results:

1. If the red LED #6 lights a significant problem exists. The red LED means that after being charged the battery’s voltage is not being

sustained above 12,4V (roughly equal to 50% charge in a sealed AGM battery) 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 total sulphation, 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 such as vehicle headlights being switched on while

the charger is connected can also cause the battery voltage to dip significantly.

2. GOOD TEST RESULT, but the battery cannot deliver sufficient power: Permanent damage within the battery may be causing excessive self

discharge (caused by the battery itself, even a partly damaged battery may initially retain sufficient power, but lose power faster than normal

there-after). Disconnect the battery from the OptiMate. After at least 12 hours reconnect and observe if SAVE LED #3 lights, indicating the

battery was unable to hold charge. If CHARGE LED #4 lights the battery retained at least 12,4V.
