Just replaced mine on my "03" T-Sport as initial cranking was experiencing a laboring before popping off, while snap starting with the new battery. Wife's "04" sporty battery still strong.

Local Batteries Plus Store (National Chain) www.batteriesplus.com had the Dyna battery for $78 and the one for baggers for $88 w/1 year warranty compared to HD ones being 6 months.

No battery tenders used. Bikes never sit more than two weeks without running even during cold raining season of Dec/Jan here in Northern CA.

 

y so paranoid ikeman.

 

I had a 03 Fatboy that the battery went bad the 1st winter. I replaced it spring 04 with a HD battery and sold the bike in 07 and the guy that bought it still using that battery no tender ever on that one. I bought a 08 Ultra and the battery went bad the 2nd month I had it (no tender). The replacement is in there now and I bought a tender and plug it in when its sitting. You never know about a battery some last forever some don't. I had a cabin cruiser boat that had 3 batteries one for each engine and a "house" battery. I had a built in charger that worked like a batt tender and I could use either battery to start either engine so I left them in there to see how long it would last. I had one last 7 full seasons and the other one needed replaced 35 mos 1 month before the warranty was up. go figure ... both sat right beside each other and were attached to the tender/charger. I think batteries have a mind of thier own

 

I just replaced my battery, it was starting to get weak. (You will know)

Agree, 6 months and it went bad. Died with no warning what so ever. You can not figure. I was in the middle of a ride, Volt meter (Digital Dakota built in alarm flashes when there is a problem) had no issues what so ever, stoped & turned off the bike and the battery died. Would not even start a bike when push started and all of the lights were off et. Al. Read about it above. There is no prevention for this. I do not need any battery tender because I live in S. Florida.

 

i hv the odyssey battery... the stock one wont hold up to my abuse... i can run the odyssey dead, wait about 30 min. and normally hv enough to start the bike... only hd to do tht once though

 

I just changed my stock Battery. It was find easy starting that without warning ....dead as a nail....Had to push start it to get it home, than right out to the shop to get a new one..
