Absolutely perfect Could not be easier. Simply plug into the Canbus port and the charger gives a condition check and alerts you to battery charge state then it switches to charge mode and works with the BMW electronics to safely charge and maintain the onboard battery. Absolutely Perfect! November 9, 2015
Best charger I've ever had. Brought my BMW battery back from the dead. I tried with another charger several times, but this one did the trick. I ride, plug it in, and let it stay on. A little pricey, but worth it since a new battery was twice as much. Switching from CANBUS to normal is super easy. Highly recommend. October 5, 2015
exemplary product Truly a great and convenient product....easy to set up and great in particular for newer BMW's with the Canbus system.Added bonus is that it is half the price of the BMW unit.Longevity still to be determined. September 21, 2015
Good choice for slow charge I first used this on a nearly 100% dead sealed battery. I plugged it into a power lead that I already had installed on my bike and it worked well. This is a low amperage charger so it took nearly 2 days to charge to full. I would have given it 5 stars, but the indicator lights are a bit confusing, so for the first several hours I wasn't sure if it was charging or not. They could have designed this better, but would probably mean adding a few more lights and increasing the cost. July 8, 2015
It Works! Post review of the documentation and verifying the programming, the OptiMate has provided reliable charging. I really appreciate being able to use the powerlet accessory socket to charge the bike. All things considered, it’s not a big deal to add a SAE pigtail to the battery though. I gather there are a short list of CANBUS compatible chargers. The OptiMate seems to have a good reputation and I would say is a good option to consider. June 29, 2015
Works great at a great price I'm completely happy with this charger. It works perfectly plugged into the powerlet jack on my R1200RT and costs way less than the BMW charger. May 26, 2015
CanBus Charging I was looking for a charger that would work with my CanBus system and after looking into BMW chargers that were over the top on price I found this little gem that works out perfectly. April 9, 2015
Super convenient charger for bikes with a CANbus system This charger will do it all. Once you read manual you will easily be able to decipher what the different lights mean, and see at a glance what the charger and battery are doing. The CANbus mode of operation is very convenient to just plug into your bike with no dangling charging cable hanging from your battery. I'm comfortable using this charger in CANbus mode with my Lithium battery as voltage is restricted. Conventional mode great for lead acid batteries where peak voltage can be higher. Build quality and connectors seems very high. Worth the money as it may prolong your battery life, and save you money in the long run. April 20, 2015
