The OptiMate 4 battery charger can save neglected batteries, but is even more effective, with a new dual-stage RECOVERY and TURBO RECOVERY desulphating action. This is the best charger for Motorcycle and cars battery maintenance.
OptiMate 4 is CANbus Ready, this is the ultimate all-in-one tool for 12V battery care at home, that diagnoses, recovers from 0.5V, charges, tests and optimally maintains, automatically. Ready to use on BMW motorcycles with CANbus.
Charging: Recommended for 12V lead-acid batteries (sealed maintenance-free, gel, or filler caps) up to 50Ah
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.

Optimate 4 battery charger benefits
No risk of overcharging
totally safe for vehicle electronics
sparks suppressed,
ideal for long term battery maintenance
Auto shutdown if short-circuited or battery disconnected
Desulfates and saves neglected batteries
Optimises battery power and life
Tests the battery every hour
100% Automatic 100% Safe
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!
