As mentioned before, if you are going to use a winch on your vehicle, I would suggest the YellowTop. It is a dual purpose design that will start the vehicle and also works fine for deep-cycle applications.
Xpress is correct regarding the volume of our batteries in use today, versus other brands and that does lead to a lot of conversations about them. Here
is a link to just that and reviews about different batteries on this site. As 92 Green YJ mentioned, RedTops are not designed or warrantied for deep-cylcle use, including winches. YellowTops don't need to be drained and recharged periodically to maintain health and the quality of our batteries has never been better. In fact, keeping batteries fully-charged is really the key to extending battery life, regardless of the battery you are using.
On a personal note, a friend of mine had a YellowTop that was so deeply-discharged this week, it did not register with a volt meter. He tried charging it with his shop charger and just wasn't getting anything. I brought it to my shop, placed it on a low amperage microprocessor charger and within 24 hours the battery has 13.13 volts in it. I just checked the battery this morning.
There is a lot of misinformation out there about recharging our batteries but the truth is, if you will follow our instructions on recharging it is amazing how many batteries are recoverable. Many of the “bad” batteries returned to us now are just deeply-discharged and work fine, once recharged.
