TecMate OptiMate 4 Dual Program Battery Charger for BMW CANbus
Works as Described
Easy, straight forward...plug in and walk away. I bought it because I had a HD and knew it needed to be on a charger... all the time. Not the BMW. This charger gives you the feedback that tells you the battery and amp level and in a few minutes... all is topped off.

No fuss, no muss. Good value too!
A much less expensive option than other chargers. The perfect set up for my CAN bus equipped 2014 R1200RT. The standard BMW accessory plug makes for an easy plug and play solution. The alligator clip pigtail (supplied) and mode easily switches to top off the truck's battery as well.
Typical excellent Revzilla customer service with simple ordering and quick shipment.

This charger exceeded my expectations for ease of use and for effectiveness. Have used it for 2 seasons and it has been excellent. I loved it so much I bought one for my fiancé's bike. Highly recommended.

Awesome alternative for more expensive BMW Can-Bus compatible charger
The product works as advertised. Just take it out of the package, connect it to a power outlet and plug into your accessory socket in your BMW and it will diagnose, salvage (if neglected), charge and maintain your battery without your intervention. The instructions are very descriptive; if still confused, with a little of attention on what the device does plus reading the manual, you'll figure it out. Very happy with this charger and very glad to have saved at least 50% of the cost if compared with the recommended BMW one, with no compromise.

High Quality, Works, Instructions a Bit Confusing
Good value in a charger for a CAN bus bike. Nice to be able to charge through the auxiliary without disconnecting the battery. The instructions and indicators are a bit confusing when you first look at them. The manual needs to be rewritten. Actual use is straight forward. CAN bus models apparently will always come set for the CAN bus option. Plug it in, it will diagnose and charge, then go to alternating test/charge sequence.

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!

No brain charger
Before I knew what I was doing, I let my battery die.
Bought this, plugged it in and was back in business.
Ran a lead from the battery to the back seat compartment and keep the Ninja charged when not riding.
Sad now, it's in the garage for the winter. Maintain light is on so I know it'll start in the spring.

Does everything Automatically
I did tons of research to find a charger that suited my bike. Triumph has their own version but as it turns out theirs is wrong due to SAE/BMW connections. The Optimate 4 does everything that the Triumph 3 version does except it is rated for cold weather, costs less at Revzilla, and has the proper SAE connectors.
This tender does everything on its own although the directions are complicated. Just plug it in and leave it there as long as you want. I have been using it for quite some time.
