About 2 months ago I replaced my battery. Its a 03 and figured it must have been old and got a new battery. Well my bike had been sitting for about 3 weeks and yesterday I go to get on and ride and the battery is dead. :banghead: Now I think this just cant be coincidence. Could the alarm be draining the battery? Its the only thing I can think of. Cause the key light flashes when its set. Any ideas?

get a battery tender cause the alarm system drains the battery in about 2 weeks, this type of battery dies often when being deep discharged

My battery kept dying after 2 to 7 days of non-use. Dealer ran diagnostics and found nothing.

The Service Manager keep telling me to put it on a charger if not riding for more than 2 days. :paper:

It finally died while riding it. Then the diagnostic tests showed a bad voltage regulator. :chair:

Yea apparantly the dealer didn't run the diagnostics correctly or that would have popped up right away!!!

The other issue is grounds--all of them on the bike just one loose one will mess with your battery BIG TIME!!!

My bike is back in the shop. I am not satisfied that the battery cannot support the factory alarm for 7 days thus causing a failure to start. I am talking with H-D Corporate to resolve this starting issue with the battery.

Does anyone have an information or experience on these Spyke Super Start Batteries? Their website states that their battery # 416017 has:

• 12 volt

• 14 amp

280 CCA

• (5 15/16"L x 5 11/16"H x 3 1⁄2"W)

My bike sat all winter without a battery tender. Alarm goes into sleep mode after a while. I had no issues firing the bike up after sitting for the extended period of time

I had the same problem with the bike not holding a charge much past 7-10 days. Many people on the site had the same problem. Most everyone put a battery tender on to solve the problem.

My bike has never lasted more than a month. Not since the day I bought it. I had two batteries for a while then the one I bought died. Got the battery tender on it now but it really peves me that I have to buy another item to keep my bike in running condition. I have a Honda 750 thing sat for a year and fired right up.

the alarm is motion activated. so not sure about the area you live in but with my bike ive seen it go off with a car or truck rolling by. if it goes off without your knowledge this can run that battery down in a couple days. I dont turn my alarm on when its in my garage, but if I did I would use a battery tender. if the battery sits more than 1-2 months with no drain on it, then it should be charged up. which is another reason to use a tender. if you go buy one, dont go to a HD Dealer go buy the same thing without the hd-logo from just about anywhere for 29.99

a battery tender jr. part number is 021-0123

this bike isnt a honda 750 with virtualy no electronics what so ever. many new vehicles have stuff that constently runs on them. my mother owns a 06 BMW z4 and she cannot let the car sit more than 2 weeks with out driving it or the battery will go dead. my bike is in my garage when I dont ride so I dont use the alarm. I have had the bike sit 1 month and still had more than enough power to fire it up. but if I run the alarm then I cannot go more than 1-2 weeks. these electronics require power constently, and you have a finite amout of power to draw from. not to mention that battery in this bike is just barely big enough for the job at hand. so I really dont think its all that unreasonable to have to maintain the charge on the battery.

It is unthinkable that a $20K bike won't hold a charge for more than 1-2 weeks. Alarm or no alarm. Battery tender - give me a break... I am on my second battery now too - same issue. My previous bike - ZX1100 Kawasaki Ninja had the same battery for 7 years - yessss 7. Oops, no alarm but heh - that's a well engineered bike. This battery thing is too much for the $ paid for this American beast - well, at least I am not alone I guess. Ken

Regardless of what your opinon is regarding the bike's engineering, the Battery Tender will more than pay for itself by extending the life of your batteries, V-Rod or other makes and models. If the bike is parked for any length of time it's a good habit to get into, especially when storing the bike for the winter etc. Up here where we have 10 months of winter and 2 months of not bad bobsledding, as soon as I pull the bikes into the garage they get hooked up.These bikes tend to run way better with a fully charged battery. :2cents:

Batteries need to be topped up on a trickle charger before they are installed, have you also checked the electrical system, check the charge rates idle and underload and all connections.

I have had bikes (alarmed) sit for months and usually start no problem.

Batteries also do not do well if it has been cool.

And some times you do get a dude have you done a load test on the battery?
