Battery Tender?

I just bought a K1600B down here in southern Florida and will be storing the bike for a few months after the winter. What kind of battery tender do the new K bikes require? I've been looking on Amazon and it appears that I need to go for the one which is almost 200 bucks unless I want to take the battery out of the bike when I leave it.. Can you guys fill me in?

Re: Battery Tender?

I use the Optimate 4 on my R1200RT. It is able to wake up the Canbus so you do not have to add a connector to the battery. The model from the link comes with the plug to connect through the power port.

Re: Battery Tender?

Just about any conditioner/tender will work (not a trickle charger) if it is matched for your battery. Many attached to a permanently attached pig tail that you keep on your battery.

The Optimate 4 is an excellent solution. I fixed the fused 'Tail' connection direct to the battery and keep the charger permanently plugged in whilst the beast is sleeping. Then when we go riding I fit an Optimate USB into the 'Tails' SAE plug for phone charging etc. The USB plug also guards against battery discharge cutting off after a set time or when the battery reaches a certain level, protecting against inadvertant discharge should you leave something connected. I also ran a seperate direct battery connection under the Tupperware to the handlebars and into a Wunderlich Media Bag, again usng Optimate cabling and a USB protected outlet to charge a Power Bank and Phone contained in the Media Bag. As an added bonus my Tyre repair kit has a Air compressor which fits straight onto the SAE plug if needed avoiding the use of Crocodile clips etc. Hope this helps.

Regards,

Tony

Re: Battery Tender?

I use a Battery Tender Jr on my F800GT (also Canbus) attached to a pigtail on the battery. Total cost maybe $30. It has float mode so the battery isn't overcharged. I left it for 4 months this winter while I was in SE Asia and the bike started up perfectly when I got back. No need to spend a lot of money.

Re: Battery Tender?

The K1600 doesn't suffer parasitic drain anywhere near as bad as the LT. I only need to keep in on the charger for a couple of days every month during the winter. Battery is 5 years old. Agree also use a pigtail direct to the battery. You can run your air compressor off that or heated gear also.

Re: Battery Tender?

as mentioned connect direct to the battery with the pigtail that generally comes with the charger. Motorcycle rated smart charger.
There are many inexpensive ones if that is your issue.

Here are some to look over:

This is my favorite but I see some for 13$ hope they work.
