I have a January 2014 72 Sporty that has had some battery issues for nearly 12 months, first occured in February 2015.  If it sits for a few weeks the battery drains and needs jumpstarting.  After the third call out from HD assist I bought jumper leads and just lived with it.  Problem is I am a regular rider, I either ride every 3 days for decent distances or daily depending on my work requirements.

Parked her up last Thursday and battery is totaly dead on Saturday afternoon to the point that a trickle charger on overnight has done nothing.

Does anyone know the warranty period on the HD battery that comes with  a new bike.  2 year factory warranty is up on the 17th and I am sick and tired of a problem that should only occur on a long term park up and not a few days and believe this is a collapsed battery and should be replaced under warranty.  Having recently moved I am not sure what box my owners manual etc are in and try finding the HD warranty online, good luck.

Advice please because I am prepaired to go to battle with Morgan and Wanker and just piss this bike off and go to the alternative of an Indian or Victory, this is my third HD and a huge fan but if this is the sort of crap I can expect with a new bike after a year and talk to other owners with a similair problem its not good enough.

Jump up and down about it at the dealer but this does seem to be a problem with the later bikes wether it be the bikes electrics
Or a dud battery seeing you are riding your bike a lot with decent ks or bite the bullet and have a Indy look at it
And pay for it yourself if you like the bike ,ether way it sounds like it needs addressing

Get the battery tested for a crook cell under load, or a voltage leak by an auto elect or battery retailer. If the issue has been documented for some time (via HD assist) you may have grounds for a claim. If it was the recharging system of the bike failing, the trickle charger would work when used. If it still dead after trickle charge, it'll be the battery or a bad connection somewhere. Get an independent check over , find out what the issue really is and then hit MW up with some knowledge. It just may be a stuffed battery, it does happen. I've had 9 new HD's over the past 25yrs and have had up to 4 yrs out of the OE.

I would also have them check for regulator fault.

The weakest part of any Harley is the charging system.

I had my regulator replaced outside of the 2 years warranty, under good will simply because there  a history of battery dying.(engine light etc)

Start the question now while still under warranty. MHO

 

Hi all...Im pretty sure you only get 6months warranty on battery.

My bikes battery shit the bed before it was 12 months old,Thinking it was a warranty job I took my bike into local Harley shop where I bought it thinking warranty would have me a new battery.Shop tried to slug me $600.00 to fit a new battery,I ended up paying $300.00 after some nice language.Still to dear for 5 minutes work and new battery If you ask me.

I left my 2016 Fatboy in the shed for 7 days last week.

Checked the battery voltage this morning before getting her out for a ride.

12.62 Volts  Perfect, and thats how it should be IMO.

 

VooDoo , the genuine HD AGM battery has a 12 month warranty.

But more important is , no matter it they cover it or not, go and buy a new AGM battery right now & replace!!!!

as trying to keep a stuffed battery going is doing more damage to other components than good, your regulator will go south quick if it has not already gone, then you alternator will go and the price of a battery will seem cheap. what you need is one of those battery testers that have series of lights to tell you what voltage.

then check voltage read out when motor off, then start it up check the voltage goes up when the motor is runing, if it don't you might need a new regulator but also have alternator checked too. when everything works as should never have an issue & a fact , batteries last longer in cool climate than hot climate. they don't like heat.
