What kind of battery do I need for electric winch?
For instance, a 12000 lb electric car trailer winch needs a 12-volt battery that is rated up to a minimum 650 Cold Cranking Amps (CAA) if it’s a lead-acid battery. Good thing is, you will see almost every electric winch has a recommended battery rating. So, it’s not that hard for you to know the exact requirement.
How much battery drain from using an ATV winch is normal?
How much battery-drain from using an ATV winch is normal? Rated winch pulling capacity Typical full-load current draw 1500 lb 100 A 2500 lb 150 A 3500 lb 200 A 4500 lb 250 A
How long can a winch run under full load?
Some recommend using the batteries Ah rating to calculate how long you can winch under full load. In theory, a 14Ah battery should be able to provide 200A for 4.2 minutes. For high amp draw applications such as winching, I find it more relevant to look at the battery’s CCA rating (cold cranking amps).
Do you need to unspool the winch on an ATV?
There is no need to engage the winch motor to unspool the winch cable. Plowing is where most ATV owners run into issues with the battery draining faster than the ATVs charging system can keep up. You typically start the ATV, use the winch intensively for 10-20 minutes before letting the ATV sit until the next time it snows.
Do you need a special battery for a winch?
The short answer is that Powersports batteries are just not designed to handle the amp draw of a winch. They are not made for deep cycling, only for starting. That being said, in the real world we have winches. Having a higher CCA is a bit helpful, but what you really want is higher storage amps, and a battery capable of deep cycle.
How many amps does a 12v winch draw?
Near full winch load (12k pounds) a 12V winch will draw somewhere around 300 to 370 amps. So a single, fully charged Group 31 battery will give you around 10 minutes of winching time before dropping to 50% charge and needing to be recharged. A pair of the T125 series batteries in series will roughly double that working time at full load.
