I been using yuasa as long as I can remember. My sure I had a few other brands if I got in a jam. Mine last 4/5 years generally so long I dont let them run down for long periods. My atvs are 9 hrs away in a warehouse near my lease and they are sitting idle from the middle of Feb until middle of October. I pull the batteries and bring them home. Here I have them on a shelf hooked up to a tender.
