That can deliver 700 amps for starting . . . and would make a good starting or primary battery maybe. However, it's only 7 amp hour rated, meaning if you use it to run a winch, you won't be winching for long with much of a load.
7 AH will give you 7 amps for one hour. 14 amps for 30 minutes, etc. 112 amps for 3.75 minutes, and 224 amps for less than 2 minutes. With a 4,500 lb winch at capacity, your talking a couple of minutes. Of course most winch use will not be at max capacity. Still, with any serious winching, a 7 amp hour battery is not much.
