I want to get a higher capacity battery for my LR-S. I find that its a bit hard starting too often along with the occasional VINERR. Unfortunately I don't have any way to hook up a tender so my only alternative other then bring the battery up to my apartment is to get one with more capacity.

I would jump on one of the new(ish) LiFePo's, but the stories of them burning down bikes makes me uncomfortable.

I know the standard batt is a 6598997C/ETX20L but I'm wondering if anyone has found one that can cram into the battery bay that has more CCA then the stock (what is it, 18ah, 270CCA?)

I already did a search with not so much helpful results. Maybe I just don't know how...

Any suggestions?
(And just to be 100% clear, there is no way, no how I can get power to use a tender - Underground, no outlets, no power at all in the parking garage)

 

I'll be watching this one too. I want to add a better one myself. Although I did just see a thread about a better battery that DK sells. I think it was an antigravity brand.

 

The stock battery as stated on the HD website is 280CCA. Battery Mart lists a few batteries with 310 CCA for your bike...check out the link below..

Battery Mart has a good line of battery's. Their "Big Crank" has good numbers and a one year free replacement warranty. Having said that, a one year old scooter shouldn't need a battery. Probably already have .. but ... what does your dealer say? Have they load tested the battery and checked you charging system for proper output?

 

Sounds like you need a new place to live.

this guy is local to me and i have had a chance to chat with him many times .. he is very bike knowledgeable and eager to help .. i'm going to have him hook me up when the time comes .. what's not to like better battery .. save weight .. good prices (from what he and i discussed) .. hope this helps .. mbm48

ps. my contact told me that the Shorai LFX36L3-BS12 is the one that fits the Dyna

 

The big cranks are made by the same manufacturer that HD uses.. Deka.. I've not had any luck with those batteries after about 2007, they last about the same.. Started using Yuasa GYZ series batteries and have used Big Boar and Braille in the past.. It's my understanding that Braille and Big Boar were made by Yuasa.. I can order one from Summit Racing and get it the next day UPS regular..

this is what i just bought for my fat bob . the stock one was getting weak. good price also..

 

Not sure if it'll fit a dyna, But I just got a Yuasa 500cca, WOW spins like a top now. Added 2ga wires while at it so the juice can get to the starter.They should have one for your model.

 

Oh and as far as a tender goes. Just riding is keeping it full. I plug in the tender and it goes green in just a few seconds.
