Too much power??
Hello all...I have a question about batteries...A little history...I've owned a 91 XLH 1200 for 15 years or so...I make it a habit to replace the battery every 4 years...I know that might be a bit too soon but I figured I don't need battery problems when I'm 50 miles away from my shop...Anyway, the last time I changed the battery I was told at the battery place that the original battery was 255 amps but for a few more dollars I could go with a 270 amp or a 310 amp...I went with the biggest one and boy did that thing spin over alot easier...However since then I had to replace 2 starter relay switches...Not a huge deal ( $13 and 10 min time ) but a PITA none the less...I've been told by our electrician at work that the amp increase should have nothing to do with it but I just find it curious about the timing...Now to the question...I recently picked up a 06 Super Glide that I've decided to get a new battery for this spring...Do any of you Dyna owners think I'm asking for the same type trouble if I go for a bigger amp battery here?...Any opinions/experiences are most welcome...Sorry for the ramble...Thank you.......

Question is why do feel the need for a high output battery? If the stock one worked just fine, why spend the extra $$$? I'm no expert, but if you are using a high output battery, I would think your starter would also have to be high output to be able to handle the extra torque.

The higher amp rating of the battery would only cause the relay problem if the starter is drawing the available extra amps. I would have the starter checked. The problem should not repeat with the Dyna.

As I stated before, the battery I replaced was 4 years old...Seemed to me it was not as strong as it once was...I get out of work At 5 AM and alot of times its 40-50 degrees out...My XLH turns over a little hard in those temps...I just figured the extra power would be a benefit for the 10 and 20 dollars more for the bigger batteries...The mentioned mechanic told me the starter would only draw what it needs so you may be on to something pamtmnm...I just didn't want to repeat my mistake if it did indeed turn out I made a mistake...Thanks for the responses..........

I am not sure if you have one but if not add a Battery Tender to your list of Harley toys. Simply plug it in every couple of day while it is cold and keep the battery at full charge as well as prolong the life of your battery a year or so.
Well worth the $26.00 or so they cost.

You should have no problems fitting a higher output battery. In my experience you will achieve exactly what you want, better cranking in all conditions. Several years ago I had my motor tuned and the battery I had struggled to turn it over. I bought the strongest battery I could find which worked well. That battery has now gone to the great battery graveyard, but the starter and everything else is as it was and still working fine, now turning over an S&S 107!
