NOTE 1. For safety reasons there is an overall time limit of 48 hours for programme stages 3.2 through 4.2.
NOTE 2. Some sealed "MF" or "AGM" batteries that have been neglected may cause the programme to advance
to the CHARGE VERIFICATION stage (4.2) without proceeding through the bulk CHARGE stage (§ 4.1). The built-in
diagnostics will detect and correct this anomaly. The circuit will oscillate between bulk charge and verifi cation as
described in § 4.2.
5., 6. and 7.
Voltage retention tests alternating half-hourly with battery maintenance
The fi rst VOLTAGE RETENTION TEST period of 30 minutes follows § 4.2, thereafter a 30 minute MAINTENANCE
period. These 30 minute TEST and MAINTENANCE periods then alternate for as long as the battery remains
connected. Delivery of current to the battery is interrupted for 30 minutes during voltage retention test periods to
allow the battery to rest (thereby minimizing loss of water from the electrolyte) and to allow the circuit to monitor
the battery's voltage decline to determine its ability to retain charge and deliver power.
5.
For batteries with a good state of health the green LED #5 should fl ash at the start of the test period and
continue to fl ash for the full 30 minutes until the next 30 minute maintenance period commences, when the
LED indication reverts to steady. If the battery remains in circuit with the electrical system it supports, and
accessories or lights impose an electrical load on the battery, the green LED may give way to one or other
inferior LED indication during test or maintenance periods. See table below.
6.
At some stage during the test period the yellow TEST LED #6 may start to indicate alone or together with the
green #5 or red LED #7 according to the severity of the voltage decline. See table below. Normally voltage
drop is associated with some current fl ow see the NOTE following § 10 below. For a good battery remaining
in circuit with the electrical system it supports, if the decline in voltage resulted from a current drain out
of the battery which was only of a temporary nature, the LED indication can revert to a better level, ideally
green.
7.
If the red LED #7 alone, or the yellow #6 and red LED #7 together start to fl ash during a 30 minutes test
(or steadily during a maintenance period), a signifi cant problem exists. Read the NOTE and FURTHER NOTE
below the table.

NOTE: For any test result other than green #5, remove 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
a problem in the electrical system it supports, not in the battery itself. You are advised to read the following note #6
and 7 and to consult an electrical specialist.
FURTHER NOTE ON LED INDICATIONS #6 and 7: If the above re-test results in a remark in the above table other
than GOOD or VERY GOOD, you are advised to take the battery to a professional service workshop equipped with
™
a BatteryMate motorcycle battery tester-charger ( www.batterymate.com ) or a TestMate
(www.testmate.com ), for a more thorough investigation. The red /yellow+red LEDs #6 and 7, (or yellow LED #6
alone for a sealed motorcycle battery) 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 total sulphation, or, in the case of a battery still connected to a vehicle's wiring system,
the red LED #7 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 the headlights being switched on while the
charger is connected can also cause the battery voltage to dip signifi cantly. Always remove the battery from the
electrical system it supports, reconnect the OptiMate
