I have an older polaris that I put a plow on, it lifts by the winch,if I use it for 4-5 hours the battery starts to loose power( will lift slow or not at all) it is a new battery(small motorcycle type) should I up grade the battery to a car size one??
You are right. My winch uses more power than the alternator puts out. It will kill a battery with constant use.
I am going to buy a new battery for my Teryx. Most of the guys on the TeryxForum and TeryxHq who use a winch have upgraded to bigger / more powerful batteries. Most prefer the Optima batteries but there are other options.
