I'm gonna trickle charge my battery on my 1995 K1100rs over the winter months, is it just a matter of plugging a charger into the plug on the side of the bike? Anything to watch out for? Can it just stay connected indefinately?

Yes that works, but make sure it is a good charger that is designed to trickle charge safely, not a cheap one that will overcharge the battery. I have one of these although I rarely use it seeing as we can rife all year 'round:-

My boat needs a bigger one so for it I have one of these:-

Yeah, you need one of those 'battery tenders', the type that will monitor and cycle on and off to keep the battery topped off.

These are getting good reviews, Considerably cheaper than Optimate

or if you don't have a "smart" charger, plug it into a timer that you can program to turn on for a short period daily.

or better yet do like I do- have multiple bikes in the garage and move the charger to another bike each week. (hint here folks Shocked )

Hi Tim, can you use 12v plug on the side with this one?

You can't go wrong for $30 for a Battery Tender Jr., plug and play....

I leave it plugged in all the time, I got 6 years out of my last Yuasa wet cell, I expect even longer from my new Odyessy PC680...



If you get the powerlet adaptor, it plugs right into the BMW powerlet plug.

Hi Tim, can you use 12v plug on the side with this one?


Yes, & the one on the handlebars. I would ditch the ring tags & fit a plug (+ve centre pin). That way one can use the croc (alligator) clips on a loose or car / Caravan battery too.
Bear in mind that these only give 3 amps max, so ideal for maintenance charge, but to fully restore a 19Ah battery would take 6 hours or 30 hours for an average car battery. Which is why I went for an 8 amp charger. With that, if I found a flattened K battery, there would be enough charge to start engine in 1 1/2 hours.
Yes it can be left indefinitely,
BUT if one or ones missus switches my old Optimate 2 off at the mains whilst still connected to the bike it WILL flatten it quicker than never connecting it in the first place DAMHIK.
