Do you mean "Pedaling"?
Because I know that I'm not selling anything...

Joe, sorry for crapping up your thread. Its good info and fantastic that you shared this with peeps that may have questions. Hoping someone like Lamont will clean it up so the tech doesn't get lost in the banter.
Bob, my (as well as other peoples) problem with you is that you go out of your way to stir the pot, create controversy and play cheerleader when stones start to get thrown for your own amusement.
Maybe try offering up good sound advise of your own, share some personal mods, repairs, and journeys, instead of jumping on the bandwagon and playing cheerleader to controversy.

You just can't help yourself can you?...

Thank you Joe, when I got my 2013 RTL the dealer put in the pig tail for the tender.
Just a FYI for anyone looking for a Battery Tender. At most of the MC/Spyder dealers they want $60.00 plus for the bigger unit. At Walmart they sell it for about $58.00, but if you go to Walmart online they have it for $48.00. I went to Walmart picked up the unit went to customer service showed they the Walmart online price on my phone and they gave it to me for the online price.

The bigger units have more capability and some really cool additional features. A good friend just picked one up that does 4 batteries at once, from car to lawn mower.
However, the little Jr units do a great job with these smaller power sports batteries, especially if you only have one machine.

One more point!
Lead-acid batteries self discharge. The rate is typically somewhere between 5% and 10% per month and it gets worse with age. Glass mat after market technology reduces the problem but doesn't eliminate it. I haven't yet measured the parasitic discharge rate on my unmodified 2014 RT-S but I suspect it will not be zero. I plan to do so in the next few days and I will report back. Even if the parasitic discharge is zero, the battery will still need charging at least once a month or so for maximum life.

I wouldn't advise charging more than 1 battery at a time. The charging voltage profile needs to be different depending on capacity and state of charge. Battery charging is actually a pretty technical subject. I developed monitoring and charging strategies for experimental vehicles for the Army for a year or so and it took a while to come up to speed.

The larger 4 and 8 battery units provide individual battery monitoring and charging. I think some of them are actually sequential in the charging operations rather than actually charging all at once.

Float charger
Has anyone used the little Harbor Freight float chargers that sell for $9.00?

Do you have a link to them?
(Not familiar with their products...)

Yep, very cool units if one is in the need for what they can do.

The HF units likely work fine. However, seeing as I have to leave it plugged in while unattended in the garage, I'd probably pony up the few extra bucks and buy name brand....

I’ve had several of these little tenders over the years and they seem to work ok, but all batteries go bad over time. About 3 to 4 years is all I get out of a small battery. They only carry a six-month warrantee. The sealed batteries from “Interstate” seem to last the longest and give the best performance. I’ve used these tenders mostly on small batteries like the jet ski, quad runner, lawn mower and motorcycle. The larger batteries like in the cars and the tractor, which we used more often, never need a tender. What seems to help the most on the small batteries is to remove the battery from the machine and bring them indoors if the machine is exposed to long periods of freezing temps. It’s the little guys that need the TLC.

I just sold a bike that I put a sealed battery on in 2001 and it was still good. I could leave the tender off for several days and it work still crank. I could leave the bike for months on the battery tender and when I wanted to ride just hit the starter and it started as if I had rode it the day before. We have two bikes we bought in 2009 and they have the oem batteries on them and they start at the first push of the starter button. My riding lawn mower has an 8 year old battery on it and it is the same way. I have battery tenders on everything that will sit a few days without being used and I never have any problems with anything starting and I VERY SELDOM have to replace a battery.

I'm a firm believer in the use of Battery Tender's(jr .750amps). Immediately after riding I hook up my battery Tender. I use them on all my bikes and tractor and leave them on till riding. Once I'm home I immediately hook them up and leave them in place 24/7. Using this technique, I have had batteries last over 9 years. Remember, once a battery begins to sulfide, it is on it's way out.
