Brought new HD battery on 6-8-14, battery stayed on tender during winter. Went to start bike last week and bike started right up. Shut it off to change into riding gear. Bike wouldn't start when I returned. Dealer said that it was a dead battery. Original battery lasted 7 yrs, this one 3 yrs. I guess it's possible.
My first OEM battery lasted a little less than 3 years, my second OEM battery lasted 4 years.
After my second one died while I was on the road, I bought me a Antigravities XP10 jump starter that stays in my saddlebag.
I think batteries are a hit and miss, but I've come to just figure every 3-4 years I'm buying a battery.
BTW- I decided not to go OEM on my last battery and went with a Duracell SLI34M which has a 3 yr. warranty.
Reason being is it was in stock at my local Batteries Plus and when ordered online was $115 with tax which if I recall correctly was about $30 cheaper than OEM which only had a 1 year warranty.
When I push the switch the bike starts so the Duracell is doing it's job and with the 3 warranty I have somewhat peace of mind until Jan. 2020.
Batteries in our bikes last ON AVERAGE 3.5 years. I say this from experience selling batteries almost daily at my shop. People that keep their bikes on a tender will get another year, year-and-a-half out of them on average. These numbers are for good quality name brand batteries (Yuasa, Deka). That being said, 3 years out of your second battery is not great but you are in the ballpark for average life.
Don't feel bad,bought a battery from Parts Unlimited once lasted maybe a week.They made good on it but who knows how long it was sitting on shelf in warehouse.

There is a code on most batteries that indicate date of manufacture.
You can google it, but it does let you know if you are about to fork over hard $$$ for a two year old shelf sitter....
I've come to the conclusion that not all HD batteries are created equal. I've had them last as little as a year and up to 5. The battery I have in the bike now is 3 and still strong. Th one before it, barely lasted a year. I always keep the battery on the tender when the bike isn't in use..
Just received a call from the dealer, was told the same thing that you guys are saying. I was also told that because I have a thunder max it draws more current. Was also told that because of the dead battery, the TM had to be reset. Any thoughts? Thanks
I just replaced my OEM battery after three years. It was on a tender any time it was not on my bike. Non HD batteries on tender have given me much more. I replaced my last non-HD battery after five years just as a precaution. I bought a Yuasa GYZ because it is supposed to be the best for handling high loads from large engines and accessories. Time will tell.
