TecMate OptiMate 4 Dual Program Battery Charger for BMW CANbus
Good product for new CANBUS BMW's
I have this battery charger plugged into the onboard power socket on my 2014 R1200 GS. I periodically monitor the operation of this charger as to it's indicator lights and it is functioning properly. I have not started the bike since we are in the dead of winter. I expect this charger to have properly maintained the battery over this extended down time.

Optimate 4 Function is Very Confusing
I bought the Optimate 4 mainly to charge a 2014 BMW R1200RT. When properly programmed (and this is very difficult and confusing) it performs as described. However, instead of having a switch to change from standard charging to canbus charging, the unit must be grounded out, plugged in and observed for a number of LED's to blink a number of times and then verify which set of LED's remain on to determine the mode of the charger. This process must be reversed ungrounded to change back to standard charging mode. I still get confused which mode the unit is in and must consult the manual routinely. Surely there must be a better unit on the market.

great CANbus charger
I bought this charger for my BMW after my battery tender gave out after years of faithful service. I was attracted to this charger in that it would charge via the CANbus port on my BMW, but didn't come with the traditional BMW parts price premium.
The charger arrived right on schedule (in typical Revzilla fashion) and I plugged it into my bike. The LED sequencing for the different charge intervals is a little inscrutable, but after decoding the LED sequences by reading the manual a couple of times I convinced myself the charger was working as advertised. I have used the charger for several months now and it works great.
I am very happy with the charger. It is much more than just a trickle charger, it maintains and diagnoses your battery. The LED sequences associated with the various diagnostic and charge modes are baffling, but once you get your head around the sequences you can always see at a glance what the charger is doing to your battery. And I love just having to plug the charger into my CANbus port after a ride.

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

Does everything well, and for less
If you have a newer BMW using CanBus, you know the difficulty of finding an easy charging option, and the cost of the OEM charger. This charger does everything the OEM charger does, plus more, and you save a $100. It's hard to beat that.

Extra cables were provided for battery posts that i converted for use on my Honda, so this device works great for my BMW R Nine T as well as my Honda CB500X. Great product.

Top quality product
Searching for a fail-safe charger that would work on every one of my bikes, all of which have different types of batteries from 2004 to 2014 models, this product is perfect.
The ability to mount it on a wall is a nice added feature. I would definitely recommend this product.
