For a limited time, just enough time to start an engine.

How long does it take to winch a boat?



If you want the total battery capacity, you want the "reserve
capacity" which is often expressed as 90 minutes at 25 amps.

Unfortunately, Cold Cranking Amps is a measure of battery capacity to
store energy, not an indication of how much current it can supply at
any given time. See if you can find an actual current requirement on
the winch, i.e. number of amps.

If not, you would be better off buying an automotive battery
recharger. One that is capable of 'boosting' or starting a vehicle,
would have no problem running a 12V winch. For that matter, if you can
get your car close enough, you could use a good set of jumper cables

from the car battery to power the winch.
