Recommended Battery Tender

This is what I use to tether my Triumph Rocket, I think it is the same on a triple, the links are for Amazon USA.

I bought the cheapest I could find as I needed a couple of them and the basic Oxford chargers seem to work perfectly.

 

Depending where you are in Colorado this

sort of thing or a cheaper model in the CTEK range should see you right.

 

I have the Optimate 3+ and have used it with both a Rocket III and an S3 without a hitch. So I'm sure the new version 4 will keep your battery in top notch condition.

 

I was told a long time ago by a specialist that keeping an Optimate type charger permanently connected up is not a good idea, batteries need to be used, ie charged and drained regularly to keep them in good condition in the long term, I only connect a charger to my StreetTwin occasionally, or any of my bikes for that matter, no problems so far, but I guess alarms and immobilisers should be taken into account.

 

Nope ..have to disagree...my Oxford Optimiser was stuffed from the factory...trouble was it was a good 6 months before I realised it.
Optimate is the better option
I have a double one doing both bikes in the front garden these last 3 years...works perfectly.

 

Both mine have been functioning perfectly for about 7 years now and they’re almost permanently switched on, you must have had a duff one.

 

I've been using a Battery Tender for over 8 years with excellent results. My husband and I have four bikes. (Well, I have three and he has one. lol) Anyway, we have two of this model and connect two bikes to each one. They are pretty much plugged in any time we're not riding. I've heard about letting the battery run down and not plugging them in all the time but our method seems to work well for us. We get long life out of our batteries and the bikes fire right up first time every time.

I use an optimale 3, connected during low season continuously, BUT power it through a time clock. Every 12 hours, 2 hour charge. Works like a charm!

 

Good idea, I’ll have that one on you

 

(Well, I have three and he has one lol). Hahaha I love it, good for you.
