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, disconnect the battery from the electrical system it supports, and
reconnect the OptiMate Lithium. 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.

The ampmatic™ CHARGE program automatically determines
the most efficient rate of charge current for the connected battery,
4
according to its state of charge, state of health, and electrical storage
(Ah) capacity. The delivered current may be anywhere from 2.5A to
9.5A (16V: 7.5A) (within normal safeTº temperatures, see page 5).
3
For batteries with an electrical storage (Ah) capacity less than 10Ah
charge current is automatically adjusted lower to an average equal

to battery Ah capacity, e.g. a 2.5Ah / 2500mAh battery receive an
average of 2.5 Amps.
NOTE: For safety reasons there is an overall charge time limit of 24

LED #5 : BLUE This final charge mode starts when the voltage has reached 14.4V
(16V: 18V) for the first time during STEP 7.
The ampmatic™ current control program now delivers pulses of
5
current to equalise the individual cells within the battery and optimizes
charge level.
4
Minimum charge time is influenced by initial State Of Charge as
measured during STEP 3, varying between 10 minutes for a battery
3
with 80% or higher state of charge to the maximum of 120 minutes for
a battery with 40% or less.

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 (LED #7, LED #8) 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%).

The MAINTENANCE CHARGE CYCLE consists of 30 minute charge
periods followed by and alternating with a 30 minute 'rest' periods,

During the 30 minute* charge cycles current is delivered only if the

The BATTERY REFRESH CYCLE is performed if the charger detects the
battery has suddenly lost significant charge. The program reverts to
STEP 8 (LED #5) before returning to STEP 9 and STEP 10 .
