TecMate OptiMate 4 Dual Program Battery Charger
Plugged right in to my F800 GS accessory socket and was good to go!
Recently bought a 2010 BMW F800 GS. Probably not the best idea as the season is over but had the itch. Quickly realized I couldn't use my battery tender without by passing the can-bus system. Pressed for time I ordered TechMate Optimate 4 on revzilla and right out of the box, works like a charm.

All set to go right out of the box
I bought two of these for putting our BMW's to bed for the winter. Much less than the BMW brand and plugs directly into the accessory socket (CANbus). Easy ordering, fast shipping.

Excellent Battery Tool
The Optimate 4 is all it should be and works as designed on my new 2013 BMW R1200GSW canbus system.

Quality at a fair price.
Purchased this unit to utilize the factory plug on my 2009 BMW R1200GS. Works with the CANbus as advertised, and was delivered set to the proper program for my application.
It is a nice charger at a fair price, unlike the BMW unit. Would highly recommend to others.

This is an excellent and better alternative to the BMW canbus charger sold for double the price. Not only charges your battery but rehabs it too. Excellent product.

Excellent for BMW motorcycles with CAN-bus system.
The engineer I spoke with at TecMate said some Optimate 4 chargers manufactured with a certain date stamp may or may not operate correctly with the BMW CAN-bus system, but mine with that date worked perfectly. If it had not, TecMate would pay shipping both ways. Doesn't get any better than this. Cheers, TecMate!

Great Unitt but needs a firmware update.
I have had this unit for a few weeks now and though it does charge the battery well on a can bus system, it does not perform the long term maintenance due to older firmware.
I recently bought a 2013 BMW R1200GS and the Optimate4 chargers that have either the numbers 0311 or 0711 stamped on the bottom cover work not work with my bike or the BMW RT models unless the firmware is upgraded by TecMate.
TecMate is going to send me a return label so that I can send the unit back to Toronto, Canada.
It is a bit inconvenient, but no big deal. It still is a great charger and costs half of the one sold by BMW

High quality product without the high price!
Instructions are a bit confusing, however the charger works excellent and is less than half the price of the BMW charger. And as always excellent service form revzilla.
