[Cvo dude]

I have a 2012 cvo ultra that the battery gets low enough that it just won't turn starter over after it sets for a week or so. Question is, in my area I'm finding a deltran (battery tender) and a shumacher and which output .75 or 1.5 to keep battery up to snuff.

[Rooster]

I think the security system slowly eats the battery but I could be wrong. I just plug mine into battery tender every time I park it when home. My 96 WG is 8 or 9 years old and still cranks but next year for sure it gets a new battery. I don't remember output.

Sounds like you will need a battery b4 long, but the battery tender will solve your problem for a good while. Deltran is my 1st choice and appears to have the nod from most on the site.

Deltran, float at 1.25 to 2.5 amps, install the pigtails so you can plug in w/o removing the seat.

Battery Tender!

I have a 2012 cvo ultra that the battery gets low enough that it just won't turn starter over after it sets for a week or so. Question is, in my area I'm finding a deltran (battery tender) and a shumacher and which output .75 or 1.5 to keep battery up to snuff.

The Deltran is tried and true. A battery tender is not meant to charge a dead battery, or one that is extremely low.  It is meant to maintain the battery by sensing when the battery output voltage drops below a given set point...it then turns itself on, charges the battery back to full capacity, and cuts itself off.  It's "smart" and can be left hooked up all the time when the bike is parked. The amp output is not all that important in this application.  If you need to charge a half dead battery, you'll need another charger with higher output for a quicker charge.  If you get in the habit of hooking it up every time you park the bike in the garage, your battery should easily last for 4 years or more. Even after a long ride, when you hook up the tender, the unit will go through it's "cycle" by showing a yellow LED light, then after a little while the green LED will light up and remain green until it is disconnected and connected again the next time.

Of course, on trips, when the bike is ridden every day, the tender is not necessary.  But when riding locally, it's best just to get into the habit of hooking it up when you park the bike at the end of the ride. There are various electrical/electronic things (that's a technical term   ) on the bike that drain the battery when sitting...not big loads, but enough to discharge the battery to some extent.  Once a battery is allowed to remain discharged for any period of time, it really never fully recovers to 100%. The tender helps prevent that.

I have been using the same battery tender for 11  years on my bikes.Everything that sits unused for over a week at a time has one.

Crap!!!!! I do the same thing and yours outlasted mine ....

The rumor is true.... didn't make it to 8 years but after 7 years and 7 months I finally got a new battery. Local dealer was having an event/sale today and you could pick an umbrella out of a cup with discounts of 10%, 15%, or 20% off... must have had my lucky rabbit foot with me today I picked a 20% off umbrella and got an OEM battery for $136.76.

If the battery is actually good (have it tested), you shouldn't be having starting problems after sitting only a week or two, even on a late model bike.  While it's not a bad idea to just connect a battery tender after every ride, it should not be necessary.  What keeping a battery on the tender all the time will do is help hide a problem with a weak and dying battery until it just fails completely.  Been there, done that.

My suggestion would be to first determine if your battery has lost capacity (load test) and is a candidate for replacement.  Assuming the battery tests out as good, then the electrical draw should be checked to make sure your electrical system isn't drawing excess current.  There are specs for what each system should draw when the bike is off, such as the security system, radio memory, etc..  There is no way a good battery should go flat after sitting for only a week unless you're starting, riding a very short distance, shutting down, starting again, and riding a short distance back to the garage.  That sort of thing won't let the charging system fully charge the battery.

another thing to keep in mind is when your store your bike for long periods of time  you should keep your key fob away from bike .....so they wont be able to  communicate between each other ..

You mean like two furbies?

My 2003 SED is always "Tendered" when in the garage since it can sit a while between uses and often goes on short rides.  I am still on the original battery...eleven seasons later.  Will probably replace in the spring.

Does that keep the drain higher?I have always left the fob in the left storage box.
