OptiMate Pro 4

The high voltage and pulsing recovery mode of the Optimate Pro 4 is able to save a neglected sulfated 12V lead-acid battery unable to accept charge from a standard charger.

If necessary, 2 or 3 stages of high voltage and oscillatory pulsing are applied to recover neglected, flat batteries (disconnected from the vehicle) from sulfation to a chargeable state.

A “MUST HAVE” MULTI BANK SHOP CHARGER FOR DEALERS

• This NEW 4-bank shop charger initializes new sealed & filler cap batteries in 1 hour, plus desulfates & recovers neglected batteries.
• Select NEW or USED battery selection.
• Select NEW and a battery receives the correct initialization charge within 1 hour.
• The USED program allows optional selection between two sizes of battery (<10Ah>) and the rest is automatically done for you.

The high voltage & pulsing recovery mode is able to save a neglected *sulfated 12V lead-acid battery unable to accept charge from a standard charger.

Battery power is optimised during bulk, absorption & cell balancing charge modes by the micro processor controlled AMPMATIC program, a unique feature that automatically ensures the battery receives optimal current every second, and then tests to verify charge retention.

Automatic safety features include quick identification of a severely shorted battery, 12 hour maximum program for USED batteries and electronic reverse polarity protection.

A metal wall bracket is available for easy & convenient wall placement and the unit comes with battery clips that have a cable reach of over 8ft / 2,5m.

NEW BATTERY = 1 hour / 4Amp PROGRAM
MAX charging time is 1 hour with maximum current automatically set at 4A.
Battery impedance dynamically changes as charge is delivered to the battery.
The Ampmatic program varies current according to battery impedance to bring the battery to full charge as quick as possible without ever overcharging the battery during the first charge cycle.

Charge modes – Bulk & absorption / cell equalization
Bulk mode – current is controlled by the Ampmatic program until the battery voltage has risen to 14,3V.
Depending on the capacity of the battery this usually occurs within 30 minutes.

Absorption & cell equalization mode – for 10 minutes the voltage cycles between 13,6V & 14,3V as the Ampmatic program varies the current. This cyclic action effectively activates new battery cells below the natural gassing level of the acid, ensuring that no pressure build up occurs in sealed batteries and overflow in standard filler cap batteries is reduced to the absolute minimum (if the battery was not initially overfilled and sufficient time was allowed for the acid to settle after filling).
If during the 5 minute verification mode the current demand from the battery remains high, charging returns to absorption / equalization mode until the 1 hour charge period has expired.

Test period: for 10 minutes charging is suspended and the voltage is monitored.
A good test result indicates the battery successfully accepted the first charge.
AGM batteries are expected to remain above 12,7V (green LED).
STD batteries are expected to remain above 12,6V (green / yellow LED).

USED BATTERY = 12 hour / 2 Amp or 4 Amp PROGRAM
MAX charging time is 12 hours with the program moving to maintenance if left connected.
Select : 2A for batteries 10Ah and less 4A for batteries 10Ah+
Battery impedance dynamically changes as charge is delivered to the battery.
The Ampmatic program varies current according to battery impedance to bring the battery to full charge as quick as possible. The MAX current setting limits total charge into the battery in case an aged or neglected battery has suffered electro-mechanical damage that significantly altered battery impedance.

Recovery modes– High voltage & Pulsing
A fixed low current (200mA if 2A selected, 400mA if 4A selected) is injected into the battery to determine battery impedance / charge acceptance.
Normal Impedance and the program moves directly to Bulk charge mode
If there is abnormally high impedance typical of a sulfated battery – high voltage recovery mode is engaged. A voltage of up to 22V is delivered to force current into the battery and as the battery recovers the voltage will automatically reduce.
MAX recovery period = 2 hours.
Pulsed recovery mode engages once the battery’s charge acceptance has significantly increased. Current is delivered in pulses and voltage is cycled up to 14,3V.
Current is increased as the battery’s charge acceptance improves.
Pulsed recovery period is 15 minutes, after which program moves to BULK charge mode.
Bulk charge mode – current is controlled by the Ampmatic program until the battery
voltage has risen to 14,3V.

Absorption & cell equalization mode– for 10 minutes the voltage cycles between 13,6V & 14,3V as the Ampmatic program varies the current. This cyclic action effectively rebalances used battery cells whilst remaining below the natural gassing level of the acid mixture, ensuring that no pressure build up occurs in sealed batteries and overflow in std filler cap batteries is eliminated (if the battery was not overfilled prior to charging).
If during the 5 minute verification mode the current demand from the battery remains high charging returns to absorption / equalization mode.

Test period: Initial test: 30 minutes – Extended ‘cool down’ test: 12 hours.
Charging is suspended and the voltage is monitored.
If only the green LED (voltage above 12,7V) is flashing after 30 minutes the test is extended to 12 hours.
The extended test will expose suspect batteries that may seem to hold charge (following recovery), but lose power due to irreversible internal damage once the temperature lowers down to normal.
AGM batteries are expected to remain above 12,7V (green LED).
STD batteries are expected to remain above 12,6V (green / yellow LED).
