TecMate OptiMate 4 Dual Program Battery Charger
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.

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.

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.

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.

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.

I store my Ducati S2R in a non heated shed and believe the weather to be a major factory in my batteries drain. Living in NYC I put the bike recommend
Highly recommend after sitting for 2 months in a cold shed. Started up stron just after a 2 hr charge

Must have for BMW bikes with CANbus.
Very easy and intuitive to use. Plug and play. My BMW owners manual suggests putting your battery on a charger if the bike sits for two weeks or longer. Also, I love Revzilla's customer service and product follow up.
Perfect compatibility with my 2015 RnineT.

The instructions are a bit hard to follow and I had to go back and read them a few times while using the charger. There is a battery save, battery charge and battery maintenance in addition to testing modes. Each of these modes will apply voltage at three different rates depending on the condition of the battery. After using it on one battery I started to understand how it functioned and when I moved to a second battery it all made sense. Turns out the first battery is showing the beginning stages of going bad which I suspected but I would not have gotten the whole picture without watching the charger work on a good battery. At the end of the day the charger performs as stated but the instruction could use work.
