Close to dead battery. Saved!!! Oct 26, 2011
By Snoopy 5280
My battery to my BMW R1150RT was close to dead! In comes Optimate 4 to the rescue!!! What an awesome product!!!
Before using the Optimate 4, I had to push start my bike a few times and what a pain in the butt that was! I rode my bike around for an hour and still the battery would not hold the charge. I knew that I wanted to get it before winter but I ended up forking over the money (not much) late summer. What a life saver! I plugged it in via the CAN BUS on the bike and in a couple of hours, disaster averted! I highly recommend this product as it does all kinds of things beside just recharging your battery. Buy it! It's cheaper than buying a new battery!
More than just a battery charger!... Jan 08, 2012
By Two_Metre_Man
Just purchased this for my 2008 BMW R1200RT (01/2012). The bike is fairly new to me and I wanted to be sure that the battery was maintained in good condition during the winter months that involve less riding and more time in the garage.
Bottom line is that the charger was shipped ready for use on my bike, using the CAN-bus program (I'm assuming that the seller, Kinney Cycles, St. Joseph, MI, did that - kudos to them!) A quick read of the pretty straightforward instruction book (yeah, I do read 'em!) and I was able to connect the charger directly to my bike, using the on-board, front accessory socket. Uh-oh!! - the Optimate4 showed a non-retentive battery at the end of its first charge-test cycle.
I removed the battery from the bike, changed programs to Standard in anticipation of needing to do some deeper work on what was apparently a depleted battery, and started the charger again. Result from the charge-test cycle was a perfect battery! Hmmm...
Changed the program back to CAN-bus, re-installed the battery in the bike and this time connected the charger via the rear bike socket. Perfect battery showing! Moving the charger plug to the front bike socket again showed a non-retentive battery.
Bottom line is that this isn't only a battery charger. It has also identified an electrical issue/fault on my bike that I didn't know about. Can you tell that I'm impressed with this unit?! It is well-made, simple to use, thorough and well worth the money. Good kit!! :)
UPDATE (March 9, 2012) - TecMate asked me to return this charger (they arranged shipping and pick-up) so that they could upgrade it. Apparently, the issue wasn't with my bike, but in the charger's firmware. Their engineering staff took the time to review the situation and determined that.
I received the charger back yesterday, complete with firmware upgrade sticker (!) and it is now charging flawlessly through the BMW CAN-bus outlets. Just what I wanted, since it makes connecting and disconnecting the charger so simple and easy - just plug it into the BMW outlet. Excellent customer service and attention to detail on TecMate's part. Gets top marks from me!! :)
