OptiMate 4 Diagnoses, recovers, charges, checks and maintains
The microprocessor controlled OptiMate 4 uses a new dual-stage recovery and turbo recovery desulfating action that can save can save neglected batteries. For neglected deep-discharged batteries the RECOVERY mode engages automatically, while the TURBO RECOVERY mode engages for more severely neglected batteries. After doing the desafation the Optimate 4 then charges the battery, verifies that the battery is as fully charged as its basic state of health allows, and then checks for & detects dead battery cells.
The OptiMate 4 is much more than a trickle charger
Now with a new dual-stage RECOVERY and TURBO RECOVERY desulphating action .
For neglected deep-discharged batteries the RECOVERY mode engages automatically, while the TURBO RECOVERY mode engages for more severely neglected batteries.

Dual program
With the flexible microprocessor controlled DUAL Program, OptiMate 4 can diagnose, recover, charge, test and maintain your battery directly, or select the 2nd program to charge via the 12V port on motorcycles fitted with CAN-bus.
Program 2 (default setting on this model) recovers, charges, tests and maintains the battery through the CAN-bus controlled 12V socket with the supplied SAE-79 accessory (see pictures to the right). The SAE-74 set of battery clips is included for direct charging. KEY-LESS activation guarantees automatic opening & re-opening of the connection without the ignition ever being not turned on, guaranteeing absolute peace of mind during long term storage.

Multi stage desulphation – low voltage, ‘Turbo’ and pulse will recover sealed batteries, including cyclic cell and pure lead AGM.
A unique pulsing start up method will attempt to recover batteries as low as 0,5V.
Multi stage charging – bulk, pulse absorption, cell balancing ensures each cell in the battery performs at maximum.
Enhanced testing and safety – 48 hour charge timer, detection of a battery with a shorted cell during charging, 12 hour test and test at connection.
All the unique features found in each of the OptiMate battery saving charger-tester-maintainers are the most advanced in the world today, guaranteeing any vehicle or craft owner dependent on a 12V battery the ultimate in unsupervised long term battery care.
Sealed weatherproof enclosure
OptiMate 4 has a sealed “weatherproof” enclosure with wall mounts and is ideally suited for use with batteries in the water & snow powersport markets. Also includes cables extreme weather cables
User friendly ‘battery check’ at start – Want to ride, but not sure of battery condition?
The 10 second battery “Ready to Ride?” test at connection helps the user with multiple vehicles or provides hands on diagnosis of ‘tricky’ battery problems.
Features :
- Microprocessor control
- 6 step charge program
- Safe 24/7 storage charge program
- Recovery + TURBO recovery desulfation recovers neglected batteries other chargers can’t!
- Automatic power loss test
- Early warning of battery problems
- Built in wall-mount tabs
- SAE weatherproof connector system
The most important attribute of the OptiMate 4 is the safe, optimal maintenance of your battery during long term storage, achieved by its gentle maintenance cycle which automatically allows the battery to rest for 30 minutes of each hour of the maintenance cycle while it remains connected.
What does the Dual program mean on the OptiMate 4?
OptiMate 4 Dual Program includes two charging programs; the standard program is supposed to be used when connecting directly to the battery, the CANbus (BMW) program allows charging and maintaining via the DIN socket on BMW Motorcycles (models 2004 and later)
Does OptiMate 4 have a battery recovery program?
Yes, the standard program has the most advanced recovery program which saves ‘dead flat’ sulphated batteries from as low as 0,5V.
Which program do I need to select to charge over the 12v socket on my BMW?
You’ll need to select the CANbus program to charge via 12V socket on your BMW motorcycle.
There is no selection button. How do I switch program?
unplug the OptiMate, connect the clamps together, wait for the LED’s to confirm program change (the LED’s start to blink fast after 10 seconds) disconnect clamps. See picture on back of charger.

What’s the difference with the OptiMate 4 CANbus edition?
CANbus edition is delivered with OptiMate adapter O-09 which fits 12V sockets. Dual Program is CANbus compatible but will standard be delivered without this adapter.
I want to use my OptiMate DUAL over the 12v socket. Which additional connector do I need?
You will need one of the OptiMate BIKE plug cables (O-02, O-09, O19 or O-29)
What type and size batteries does OptiMate 4 charge?
STD, AGM and GEL 12V lead-acid batteries used for engine start & deep cycle applications. (Link: Learn here about batteries, this will be at ww.optimate1.com/batteries). For batteries from 3Ah to 48 Ah for 24-7 battery maintenance. Can recharge batteries up to 24Ah within 24 hours.
How fast does OptiMate 4 recharge batteries?
Charge time on a flat but otherwise undamaged battery: a 12Ah battery should take no more than about 12 hours to progress to the self-discharge check. Deep-discharged batteries may take significantly longer, a full charge may not be achieved within the hour charge safety limit. In this case.
Russel Alexander –
Best Bike charger I’ve owned to date. Have an Optimate 3 Dual charger as well and clear difference between the 3&4 in terms of speed and charge ability… But this is expected given the spec difference. Both exceptional at bringing dead batteries to life as long as there are no dead cells, which the unit will also indicate should it be the case. Now to test it on a large Car battery to see if applicable 🙂
