 Key Point: 

  • Keep your trailer winch battery charged with a trickle charger or solar panel.
  • Regular checks and clean connections are key to a healthy battery.
  • For a strong winch, pick a deep cycle battery and beefy cables.

What Size Battery For The Trailer Winch?

A battery for a trailer winch should have enough Cold Cranking Amps (CCA) to power the winch and engine. 

A 12-volt battery with a rating of up to 650 CCA is generally enough for a 12,000 lb vehicle.

Battery Type

You’ll want a deep cycle battery. Why? They’re made for this kind of job. A deep cycle battery can handle being drained and charged again and again. 

It’s different from your regular truck battery, which is more for starting up and doesn’t like being drained too much.

Battery Size

The size depends on your winch’s power needs. A bigger winch needs more power. You don’t want a battery that’s too small and can’t handle the job.

Battery Cables

For cables, go for thick ones. Why? They handle the power better and reduce voltage drop. 

You don’t want the power weakening as it travels to the winch. Strong, thick cables are like a wide road for electricity.

Winch Capacity

Your winch’s capacity tells you how much weight it can pull. This is key when choosing a battery. A stronger winch needs a stronger battery.

Physical Size and Weight

The battery should fit well in your trailer. Not too big or heavy. You don’t want it taking up too much space or adding too much weight. It should be just right for your trailer.

Battery size matters even if you are using a destination trailer as a travel trailer. These are good things to keep in mind when managing your trailer’s power needs.

For charging, you have options like a solar panel or a battery tender. These help keep your battery ready without always using your tow vehicles battery. 

And speaking of charging, how to charge a winch battery on a trailer and what type of battery for trailer winch are common questions. 

The answer? Use a good charger, maybe even a solar charger if you’re out and about. And always have jumper cables ready just in case.

How Many Days Does The Trailer Winch Battery Stay Charged?

According to someone on Reddit, 

A charger can fully charge a trailer winch battery 5 days later. There are, however, reports that a motor can quickly drain a battery.

These batteries can hold a charge for quite a bit. If you’ve got a deep cycle battery, which is common for trailer winches, it’ll last longer than, say, your regular truck battery.

Now, keeping it charged is essential. You could use a solar panel or a solar charger if you’re out and about. These are great ’cause they keep your battery from going dead, especially if you’re not using it for a while. 

If you’re on the road, hooking it up to your tow vehicle battery through a charge wire can keep it topped up.

Remember, things like voltage drops or a bad connection (like a loose pin connector or a wonky copper wire) can mess with your charge. And for safety, keep those jumper cables handy, just in case.

By the way, if you’re repairing a rip in tent trailer canvas then keep the battery in check too.

It helps to know a bit about electric brakes or maybe a snatch block, which can be a lifesaver in tricky towing situations.

Also, if you’re curious, how to charge winch battery on car trailer and what size battery for trailer winch are things you might want to look up too. Always good to know the right size and how to keep it charged up for when you need it!

Factors That Drain Trailer Winch Battery Faster 

There are a few things that really drain your winch battery quicker than usual. Like, if you’ve got a deep cycle battery, it’s meant to last, but constant heavy use can wear it down fast. Let’s see a few factors:

  • Corroded terminals
  • Faulty or worn out alternator
  • Excessive power use

But, if you forget to use a battery tender or charger, you might find yourself with dead batteries. Not fun, right?

Also, the way you wire things up matters a lot. If you’ve got a hot wire or charge wire not set up right, or if there’s a voltage drop, that’s trouble.
