Video Transcript for Complete Breakdown of the Snap-Top Battery Box with Strap for Group 27 Batteries

Hi everybody, Andy here with etrailer.com. Let's take a look together at the Snap Top Battery Box with Strap. Now this battery box is going to protect your group 27 automotive marine or RV batteries against impact, contaminants, and leaked battery acids. So this is going to be a great option to install on your boat, camper, motor home, trailer or generator. This box is made here in the USA of rugged molded plastic that's gonna be resistant to impact, UV rays, oil, gas, and battery acid. It's gonna maintain its impact resistance in extreme conditions all the way down to negative 27 degrees Fahrenheit.

So as I mentioned, this strap is included and the ventilated lid is going to secure to the box. And as you can see, it has these two fasteners here on the lid. Then that strap will hold it securely in place. The length of the strap is about 46-1/2" long. And this box has multiple exit points to allow dangerous acid vapor to be released, as you can see here on the inside of the lid, maybe you can see it, you can puncture through these holes for additional venting.

And then let me see if I can show you the inside here. Hopefully you can see that inside there are acid resistant, it is an acid resistant reservoir that's going to safely capture spilled battery acid inside the box, you can see those recessed areas there in the corners that are going to catch that battery acid that act as that reservoir. And so you can mount this a few different ways using the included screws. You could directly mount this into place, running the screws through those holes that you see there in the corners. Hopefully you can see those holes there.

So you can directly just mount this into place with those screws. Or you can use this panel here. You can just screw that panel into place, run that strap through and then this is just going to sit on there on that panel, close the lid and then you'll just tighten the strap. So this does include a small instruction sheet that can walk you through those installation options, again, with the included hardware. Now this box does have built-in handles on either side that's gonna give you a secure grip while carrying this battery.

And let's go over some measurements just so you can be confident this is going to work for you. Let's begin with the external dimensions with the lid on here. So the overall length from end to end, at the longest point, we're sitting at about 16-3/8" long. The overall width at the widest points about 10 inches wide. And then the overall height from top to bottom is gonna be about 11 inches tall. And then the lid itself, the height of the lid is about 2-7/8" tall. And then the base, it's going to be obviously a little bit narrower or tapered down the lower you go. So the base is going to be about 14-7/8" long. The width about 7-1/2" wide. And then the height without the lid about 9" tall. And then in regards to the internal dimensions, again, beginning with the length, about 13-1/4" long, 7" wide. And then the internal height, about 8-5/8" tall. So this is going to be very easy to use. Once you get your battery in place, you can close that lid and then just secure the strap around it. Again, this is a very durable box. The strap is going to be very easy to use and just run it through the buckle and then tighten it down. And that's gonna keep that lid in place. This is going to meet the federal USCG 183.420 and ABYCE-1.7 requirements for marine use. Well, I think that's gonna wrap up our real quick look today. I do hope that our time together was helpful for you. Again, my name is Andy, thank you for joining me.

The battery boxes work as they should. The straps are cheaply made and were immediatly replaced with bungi cords.



by:

This was a perfect fit for my Battleborn battery, and also where it sits on my travel trailer. As Ace Ventura would say, "Like a glove!".
The product is exactly what I was looking for.



by:

Great battery box for Group 27. Needed to cut them down in areas to fit tongue space. Band saw did a great job cutting to fit



by:

Great box for a trailer battery. Poke a couple of holes in it at the bottom for drainage of water that enters while driving in the rain and your good to go.



by:

Ample size, and should work for almost any 12v battery you use. I have not mounted the box yet, so I cannot comment as to the functionality. I have chosen to mount the box inside the trailer after deciding the openings and material of the box probably won't survive exposure to sun and moisture well enough to keep the terminals and wires from corroding.



by:

Worked as expected. Securing it with just the strap seems a little inadequate (at least for my set-up) but that can be fixed with a little ingenuity. The supplied plastic brackets (the brackets are for the strap, not the box) with small self tapping screws are also only adequate if you are going into sheet metal. Anything thicker than that and you need something more "robust".



by:

I needed a new battery box to fit a marine battery that came with the tent trailer I purchased. It worked perfectly for what I needed.



by:

We use these boxes on our camper builds and we've been happy with them. They are super affordable and we've had great luck with lids staying on without strapping them. Not recommending this, just worth noting... they clip in and are pretty secure.



by:

Superior customer service. I ordered some materials that I
didn't need and received a return shipping label immediately
so that I could receive credit for my returns.
7 foot bunk boards were of excellent quality as was the battery
storage case for my series 27 trolling motor.



by:

I needed a battery box that could accommodate a lithium battery for my camper and this one is the perfect size. It’s sturdy and is doing a good job.



by:

Everything I order from etrailer is perfect for what I need. It shows up almost as soon as I click the buy button! I have come to depend on etrailer for my camping and trailering needs. I will be dealing with them in the future. There just isn't enough good things to say about them.



by:

I haven't used it. I bought a lifepo battery which needs more ventilation.



by:

All as described. Will order from etrailer again.



by:

These are GREAT!!! Perfect fit for my batteries...



by:

I actually did not use it on a trailer. I used it on my pontoon boat when i upgraded the battery to a bigger size. It worked perfectly and is well made.



by:

Ordering was easy, package came quickly, battery box is well made and came with the tie down strap. Perfect replacement for the old, damaged battery box.



by:

etrailer is awesome - high quality products, easy transactions, and great customer service - Shipping was perfect as well!!



by:

A year later and the box is still dry protecting the battery. My old one leaked and I could never figure how water got inside of the box



by:

Excellent product quality. Exactly what I needed as I replaced batteries in our 5th wheel.



by:

Great product and great service from etrailer.com! the best!



by:

The battery boxes are great, as always. You guy's rock!



by:

  • Installing Trailer Mounted Battery to Power Trailer Tongue Jack
    Due to the importance of a properly functioning break away system, it would be best to leave the existing break away battery in place and add an additional battery for powering the jack. A standard automotive or small deep-cycle 12 volt battery would work just fine for you. I would recommend using a battery box like # 329-HM327BKS to protect the battery from the elements. The 12-volt accessory circuit from the 7-way would run to the positive terminal of your auxiliary battery, and then...

  • Electric A-Frame Trailer Jack and Battery Box Recommendation for an Enclosed Trailer
    You can get a jack and battery box from us, right here at etrailer! For a battery a 12 volt car battery will work fine. It doesn't have to be the fanciest battery (since they are getting so pricey these days) so long as it has the amperage rating for the draw of the jack you use. For a battery box you could use # 329-HM327BKS for group 27 batteries. The interior measures 13-1/4" long x 8-5/8" tall x 7" wide so the battery will need to fit those dimensions. It comes with mounting brackets...
