Default New battery...again!

Had to buy another battery yesterday. This is the 3rd battery since I purchased bike new in July of '07. 1st lasted 2 yrs, 4 months;
2nd-1 year 3 months.
This last battery was made in January of '09 (date code A 09) and was purchased at the end of November of that year. I don't believe the dealer kept it on a battery tender while it was on the shelf for 10 months. From day one it never felt like it turned the engine over on start really strongly. It left me stranded at night about 4 miles from home this past Friday when trying to re-start after dinner out.
Had to jump start to get it home even though it was always kept on a tender.
I measured the new battery at the parts counter when brought out, measured 13.5 volts no-load, he had just taken it off their battery tender. Parts man said they keep their batteries on a tender until sold. Funny thing is, this dealership (Fort Lauderdale H-D) is part of the same dealer chain as where I purchased the previous unit (now closed Pompano H-D) that apparently did not do that.
This new battery was made in February of this year (date code B 11) and received by dealer a few days ago. At least this one kicks over really strong!
Yes, checked charging system and static drain...all ok, charges at about 14 volts with lights on and engine idling. I also keep it on a battery tender.
I'm hoping to get at least 2 years out of this one!

I'm on my second HD battery ... have a 2010 Fatboy with about 10k on it ... lots of hot summer riding on West Coast and middle of penninsula in FL. Charging system check out to shop manual specs.

First battery died out in 7 months ... would not hold a charge. The stealership in Sarasota wanted to keep the bike overnight ... no way I was going to leave it with them so an 18 year old kid could screw with it .. I paid them the ridiculous over-the-counter price for a new HD brand battery (made by Deka .. in New Hampshire I think) ... because I needed a battery and I needed it right away. Next battery will not come from a Harley stealership ... NO WAY ... that is for sure. If Optima makes a gel cell that'll fit ... get one.

I've had better life on the smaller gel batteries keeping a very low amperage self regulating tender on them when the bike/scoot/snowmobile is not in daily use.

Snowmobile in Southwest Florida...Awesome!!!

Seriously though, I think it would be a good idea to bring it back to the dealer so they can measure the static drain current. Could be an issue they can find and fix in warranty. High current in off position will kill an Optima too.

I got an Exide battery from Parts Plus/Bumper-to-Bumper. It was "dry-shipped" and came with it's own matching "six-pack" of acid. I put the acid in and let it charge on a 1 amp tender overnight. Installed the next day. Turns the bike over MUCH better/faster. OEM battery was getting slow after 2 1/2 years.

HD battery price was around $120. I got mine out the door for about $80.

I changed my battery at 4 years and put it in my riding mower. It still works great. I'd bet that old battery wasn't on a tender for more than a few hours in 4 years and not at all for the last two on my mower.

Seems like hot weather state riders can expect shorter battery life no matter who makes it.

Hope you have better luck than me with Exide. I went thru 3 of them under warranty before I gave up and went back to a sealed Deka. No more issues.

Make sure you charge the new battery fully before use. The dealer only sticks it on a quick charge.
