So I went out and much to my chagrin the factory battery in the Virago 250 took a [censored]. The maintenance charger was charging but the battery wont take it. Its 5 years old so I saw it coming. Now...here is the skinny. I have an O Reilly, a Napa, and a Advance Auto in the area and all stock the 10L-A2 size I need. Any idea on which store brand would be the best buy? There are all within 4 bucks of eachother. If I recall Advance car batteries are Johnson Controls, and NAPA and O Reilly are East Penn. Not sure about their bike units though.
