I have a 08 FXSTC Softail custom 96 cubic inches; I upgraded it to the 103 kit and is looking for a replacement battery. I have heard Gel batteries are a better option to go with. I guess what I am trying to ask is that a true statement and if so, what size and type of battery fits his motorcycle? What would be the best choice for Harley batteries? Please advice appropriately. It is quite special for me, so any information regarding this would help. I hope to hear soon from your side. Thanks.
