Replacement Battery

When I bought my 2015 Sportsman, it had sat unused since Oct of last year. The battery was dead, however I charged it and everything worked fine. Since that time I have ridden the machine several times but when I start it, I can tell the battery is weak. I am afraid it will leave me stranded. So I am asking what brand battery do you experienced guys use in you machines?
