Does exactly what its supposed to do--just plug it in when the bike is in the garage, and forget about it. Your battery will always be topped off and in perfect condition.

Great display and features
Does it all. You know exactly the state of charge and function with this charger due to the intuitive and easy to read display. Way better than my "other" chargers! Very happy and a great price.

Works great and is a much less expensive than the BMW Canbus charger
I looked around quite a bit to see if the BMW Canbus charger could be purchased inexpensively and it wasn't available. After I read the reviews here I decided to go for this charger which was $50-$80 less and I'm glad I did. the OptiMate 4 Canbus charger worked great on my 2009 BMW F800ST. I knew my battery was low because our weather has been horrible and I've barely been able to ride and get my bike charged up. 2 days after the purchase of this charger I plugged this in to my bike as the battery was dead. The charger came set to the BMW Canbus mode so other than finding a wall socket it took care of the rest. I switched modes and charged my riding lawn mower too. There are a number of lights on the charger so you really need to see the instructions the first time but once you've seen them you should be all set. I'd buy another in a heartbeat. I've only had it a short while and I certainly got my money's worth.
Keep in mind that if you have anything tied into the Canbus power when this charger starts you may turn on that device. I had a GPS device tied into the Canbus and it turned on due to the charger. I ended up directly wiring the device to the taillight to avoid the Canbus issue.

Great product, highly recommended! Super easy to use and cheap in power consumption. Wired it directly to the battery with the provided cord. Best bang for the buck!

Good feedback regarding battery status
The indicator lights do a good job in showing the state of your battery but if you don't normally pay attention to these sort of things you're better off with a cheaper product. I bought it mainly because it is advertised for BMW brand bikes

This product has great features
Very easy to use and works as advertised. Plugs right into BMW CANbus with no problems.

Confusing light show, but great performance.
I purchased this charger to maintain the battery on my f800gs over the long winter in Michigan. I had the bike sitting with no charger for a couple months before I purchased this optimate. The battery was sounding weak the one day I was able to ride. Charger plugs right in to the BMW outlet and works seamlessly. The array of LEDs on the charger are a bit confusing, and I had to read the descriptions and watch a couple videos from optimate to decode what the charger was doing. The charger has indicated that it has repaired my battery, and the batter does sound audibly much better.

Craig S: I bought this for my Triumph Tiger 800 ABS. Worked out perfectly for the winter with the bike stored in our garage. Directions were a bit confusing though...would be nice to have a how-to video on the site.Jun 6, 2014
