Best replacement battery for 2007 Big Dog K9

Bought a Braille in Jan '14 when I bought my '05 Mastiff.....it's still going. I keep it on a tender since I don't ride it much anymore. But it's still going.

I've got 2 brailles and without a doubt they have been the best battery I have put in a Motorcycle since I got my first bike in 2003.

I've torn up just about everything else in 1yr or less with both my Big Dog and my BMC. (Harley, Interstate, walmart specials, and a Lithium) - Haven't used the TR racing (Tomioka Racing, although from my limited checking, I'd bet they are actually relabled Braille units, don't think a small company with a mailing address of a UPS Store is really making batteies. But I can neither confirm or deny this)

Basically -- get whatever you can afford and see what works for you -- As you can tell from the thread, there is NO clear concise winner -- every brand out there you can probably find someone here who's gotten great results as well as someone who had miserable results.

The bottom line is - We need better battery technology! Someone needs to make a cold fusion reactor -- that's the ticket -- then we can skip the engine and just get a sound effects set for the riders that need their bike to "sound right" going down the road.

Well of course I mouthed off last night and this morning the Braille wouldn't start the dog -- karma is a bitch. Although I must admit - I do have a tendency to forget to put it on the trickle charger when I park it in the my trailer/garage.

So I figured it out, had that battery about 2 yrs -- overall a wash, either pay more and get longer life or use cheapy doesn't seem to really effect the value if you do price/life.

Just saw on walmart.com battery for 54.50 with free shipping AGM 310CCA, Hell for that price I might just buy 2 now and use one and keep the other stored for whenever. Might go for the Duracell at 125 with 2yr warranty just because I can pick it up ASAP.

I have bought the ES20LB battery you pour Acid in yourself it's listed for $78 but after core it's like $65. Replace them every spring and ride.

Keep the receipt in your tool roll and then if anything ever happens on the road there is always usually a Walmart somewhere if you need to replace. Which is another reason I Kinda like it.

Hi again my friends. when I removed the original battery from my 2007 Big Dog K9, I discovered that it had some type of foam padding attached to its side like a sticker, apparently to protect the battery from some bolt heads on the side of the battery box. I tried to peel off said foam padding sticker to reuse it on my new battery, but was unable to do so. Any suggestions of what I can use as a replacement for said foam padding, and where to buy it? Thanks again for all your great and friendly advice, as I couldn't do many things to my K9 without your help. All The Best--Brac

Head over to Home depot and look for some thin closed cell foam weather stripping.

You could also use a piece of 3/8" or 1/2" plywood to take up the space.
