Technical Details
- Automatic self-diagnostic test: Immediately on connection, the microprocessor checks the circuit and flashes all LEDs (except charge current LEDs) to confirm correct operation.
- Dual-stage recovery action: If the diagnostic check determines that the battery is sulphated (deep-discharged), the first stage attempts to drive in an initial current by applying up to 16V for a brief limited period. If this is unsuccessful, the TURBO recovery stage engages (indicated by a flashing recovery LED), which increases the applied voltage to up to 22V. This action is limited to a maximum two hours.
- Charge current display: A thermometer style central LED column shows delivered current. This, together with the expanded charge programme status LED information provides the user with detailed insight regarding the progress of both the state of charge and the state of health of the battery.
- High efficiency: Despite delivering 33% more power than OptiMate 3sp, OptiMate 4 consumes less electricity, which is welcome in these days of high energy costs and eco-awareness.
- Enhanced battery testing: Green, yellow and red "traffic-light" LEDs indicate alone or in combinations to provide 5 possible results of the end-of-programme test for power drain, whether in the battery or due to a problem in the bike's electrical system.
Product Specifications
Product Information
BrandOptimate 4+
Manufacturer Part NumberOPT004
Product Description
· Diagnosis of deep-discharge or light sulphation; automatic recovery phase with precisely controlled parameters to recover many neglected batteries, even from as low as 2 Volts. In really difficult cases the interactive programme gives the battery a "Turbo Recovery" charge.
· Multi-stage automatic charging programme monitors and controls both voltage and current while charging the battery to ensure optimum charge for the battery, without any risk of over-charging. OptiMate 4 is totally safe even for long-term connection.
· Automatic double-check ensures that the battery is fully charged before switching over to maintenance (float charge) mode. If the check indicates that the monitored signals suggesting full charge were premature, the charger reverts to the main charging stage and continues this procedure until the battery is definitely fully charged.
· Hourly checks (in maintenance mode) for any signs that the battery is not able to hold its charge, or that it is being drained by something connected to it. If all is well, the green LED indicates after the first of these hourly checks. With OptiMate 4, five test results can be indicated and are continually updated. This avoids the situation where a one-off power drain (e.g. alarm) causes a red LED indication indefinitely. In this way, OptiMate 4 continues to test & maintain your battery indefinitely, displaying a real-time battery condition test result. Should a power drain or defective battery be detected, the red LED will indicate a "suspect" condition but the charging circuit will continue to support the battery until disconnected.
· Automatic cancellation of charging programme when mains power fails. On restoration of mains power the battery is automatically re-assessed and the charging programme appropriate to the battery status is immediately restarted.
· Now includes IP64 protection against water ingress.

I love this. I have a classic motorcycle and I had a problem with the battery. I thought I needed an new battery as it appeared not to be holding a charge. It tested the battery over a few days and registered it as green = good. The bike started beautifully, further testing (not using the optimate) revealed a weakness in the charging circuit that is now fixed.
As the bike is now laid up for the winter the optimate allows for the battery to remain connected on the bike and being charged via a special cable. I have the confidence that the battery will be in excellent condition whenever I choose to start the bike and am sure my battery life will be extended. There are a number of accessories available enabling you to connect a sat nav or similar in fact anything that can run off a cigarette lighter socket Extension Lead Optimate 3 and 4 Weatherproof Fused Eyelet Lead OptiMate 3 and 4 OptiMate 3 and OptiMate 4 Accessory Plug Lead (Female) Cigarette Lighter Adapter (Male) OptiMate 3 4
This is not just a battery charger the product coupled with the extras (once fitted to the bike) make up an excellent package, I'm glad I invested in one.

If your bike has Can-Bus tech then this is the charger you want (it also works with just as well on standard mode for charging with the battery disconnected or for bikes without Can-Bus system), it's simple to use, robust, reliable and does exactly what you require of it.There is a lead for plugging into an accessory socket available as an optional extra for a few pounds, which if you have a socket is well worth getting as it enables connection/disconnection in seconds.Regular usage will keep your battery in tip top condition all year round.

I have had an Optimate 3 for 9 years now and has done its' job up to now. I have owned a BMW R1200 for over 5 years now which has the new Can-bus electric system, which stops me using the old optimate through the auxilliary socket. I have had to hard wire the connections to the bike battery. Now with the Optimate 4, I can set it to Can-bus mode and use the aux. socket. It seems to work fine. Just the Job!!
The suppliers provided a very prompt and efficient delivery, about 2 days in all. Great service!!

Optimete charger
The cycel of lights taking it through it's cycle are a little confusing at first until you get used to it (the manual doesn't really explain it very well in my opinion). Read more
