Battery Tender Junior Charger - 6V and 12V

  • Perfect for all lead-acid, flooded or sealed maintenance free batteries (AGM and gel cell)
  • Complete 4-step charging program (Initialization, Bulk Charge, Absorption Mode, Float Mode)
  • Automatically switches to float / maintenance voltage after fully charging the battery
  • If the battery voltage drops too far under load, full charger output power resumes
  • Solid state two color LED indicates stage of charger
  • Spark-proof
  • Reverse polarity protected
  • 12' output cord
  • 5 year warranty

Great product Inexpensive protection for your battery, plug it in and forget it. Led gives status of charge with four responses, blinking red, red, green and blinking green. This is all you need, period. February 18, 2013
Does what it says it does My friend is storing his Harley in my garage and his battery was completely dead. I bought this thing to charge his bike (and mine) for the winter. (I still ride my bike in the winter but give it a little juice here and there). Previously, his bike wouldn't start. Now that I used this thing, she starts right up. January 2, 2013
Works just like it should. Very small unit and brings all of the cables to set it up permanently on the bike. January 1, 2013
Good battery charger The charger does what it says it does. Charges it up to full and then goes into float mode. All you have to do is plug it in and don't have to worry about it until you want to use it again. Great product! December 11, 2012
Another great Battery Tender Simple to install the pigtail, great little tender! December 10, 2012
Quality Product What can be said? If you are looking for a battery tender at a great price, this is your best bet. Worked as described and arrived on time. Thanks Revzilla! December 3, 2012
Great price for a great product! Really easy to install and works like it should. Might get another one for the car. November 19, 2012
Piece Of Mind I have 3 bikes and have the Jr. for each one. It keeps my batteries healthy and gives me piece of mind all winter long. May 14, 2012

Does the wiring harness have an inline fuse or is that harness a separate accessory?

There is a port to connect with a charger. Does this charger have the proper lead for this mototcycle? The manual says NOT to charge the battery (unless thru the port) .That means taking off the seat,etc, etc. If it comes with the lead great, or include one if you fill this order,ok? Thanks lorin

Answer: 
It doesn't - you'll have to buy a powerlet adapter if you want to plug in to the port. Note that if you go this route, there's a key on/off procedure you'll have to follow or the port will shut off and the battery won't receive a charge.

Anyway, I've had six BMWs, two with CANbus electronics whose manuals included the same disclaimer you mentioned. I was wary too, but after some research I found I was able to safely use the Battery Tender with it's included harness kit to charge directly to the battery, which I did. Note that Battery Tender ships two different harness kits; one with an in-line fuse, one without (I think the BT Jr. doesn't have the in-line fuse). I recommend only using the fused model.

BMW sells an OEM branded charger you can plug directly in to the factory powerlet, but many prefer the Battery Tender and think it's a better product. I'm one of them, as are quite a few good staffers I know at BMW dealerships around the country.

If you'd like more info, you'll find a lot of chatter on this topic on sites like ADVrider and other BMW specific forums - just do a Google search.
