Great product. I repurposed this as an APU for my enclosed trailer. It powers my LED lights when I'm not connected to my tow vehicle. So I have lights inside all the time.



by:

Excellent product and the E-trailer customer experience is second to none. Tracking, updates, shipping, and help are all perfect



by:

Used for stowing assembly and wiring for front parking sensors for my F150.
Provides for organization and protection from the elements.



by:

Installation could not have been simpler. Easy out with the old, on with the new, it was a perfect fit. Very pleased with everything from etrailer! Thanks!!!



by:

Worked great replacing the one that was full of holes after installing the junction box.



by:

This battery box ended up being an exact replacement for the one that I had that got damaged in an accident. I looked at several in a local store, and none of them were as rugged as this one. Attaches securely to my car trailer.

Its great, rugged and does the job well.



by:

This is exactly what I needed for a 12 volt battery to go in my kayak for a fishfinder. I will have to grind off a little plastic on the inside to make it fit but next to nothing on the internet was out there but this nice little box that would fit the battery inside.

Great still on in good shape.Thanks

I was replacing a broken battery box for my trailer brakes, and this box is identical to the OEM box that came with the trailer. The transaction with etrailer could not have been easier or faster. Product shipped immediately and was exactly as I expected. Excellent product, great price, excellent vendor.

WIN WIN WIN WIN: The Product, Price, Delivery & Online Purchase experience were great. I'm mounting a small 12V battery in an antique Jeepster with a stock 6-Volt system, to operate 12 Volt novelty horns during parades. I sought a battery box similar to one built onto my flatbed trailer with elec. brake system. My search of your site, and purchase took only a few minutes, and delivery was surprisingly quick. Thank you!



by:

Nice boxes. They do have plastic fins on the inside at all four corners that will not allow a 12 volt 7 amp hour battery to sit all the way down to the bottom of the case. A few minutes with a dremel tool to cut some of them off to allow my battery to fit low enough to close the lid. Well worth the price. The lid holds open by itself a nice design touch. Can be bolted closed or locked with a padlock.
Has four mounting holes. Case is motched for the wires to exit the side. Has drain holes/vent in the bottom



by:

used the box for a power wench on a boat trailer---had to modify inside to fit a larger battery but works for the job--use a solar array to charge the battery--mounted on top of the case.. no connection to vehicle alternator.



by:

I bought this to house a 12v 10 amh battery for my fish finder. It was well constructed but was a little small for this battery. I was able to stretch it out by heating it and inserting a wood block slightly bigger than the battery. It fit well after that.



by:

Well made and functional box. We are using it for a solar powered business sign. A great find!

The box has worked just fine. Good product.



by:

Excellent product and perfect for what I needed. I used it for a battery holder for my Model T Ford......couldn't be more pleased.



by:

The box itself is exactly what I had been looking for, and the purchasing process went smoothly. However, given the box is intended to be fastened to the frame of a trailer, it would have been appreciated if the hardware—4 self-tapping screws—was included. The package of screws I needed to purchase—only to use 4—cost more than the box. Tough to find just 4 screws these days since the mom and pop stores have been pretty much squeezed out. Not looking for a freebie...just add it to the cost.



by:

Very fast delivery, under a week from the time I ordered! The trailer break away box is perfect for what I need, I will be a repeat costumer. Recommend this company!



by:

Was looking for a replacement for a trailer battery box that got broken. Did not know brand, but knew dimensions. This is a perfect replacement for fit and function! Thanks!



by:

Exactly as described in summary. Excellent price for a hard to find trailer battery box. Fast shipment. Thanks!



by:

Yes the boxes showed up and they are what we wanted. We use them with magnets
to put in remote spots for our wireless cameras
Was disappointed with UPS ,was delivered to post office in our area and we knew it wouldn't fit in our mail box on a rainy day (so) had to go and get them
Thanks



by:

This is a super value item that works for many applications.
I would recommend this item for any project applications.
Product was shipped super fast, and very affordable.
thanks Etrailer

by:

Seems good quality for price.
Not sure
I would trust the mounting ears on side to carry the weight. I will support from the bottom with a 90 degree bent piece of sheet in addition to the side ears.



by:

This battery box stands up to everything! Easy for me to install and get the battery settled it and hooked up...Didn't have to wait for my husband to "get around to it"

So far I really like it...It's just a battery box, but when hauling horses, it can literally be a life saver.



by:

Etrailer was very responsive Product is exactly as expected. Received shipment quicker than expected.



by:

Bought two different boxes as there was a slight difference in measurements. I could buy both, shipped to my door, for the cost of one locally, which they did not have in stock and I would have to wait a week to get anyway. Etrailer is the best!

  • Battery Recommendation for the Battery Box # TK2051
    The Replacement Battery Box part # TK2051 that you referenced has internal dimensions of 5-15/16" long x 3-1/8" wide x 5-1/2" tall and is designed for breakaway batteries like the # HM20008 that would easily fit in the box. This battery measures -1/2" L x 2-3/4" W x 4" H.

  • Can Trailer Breakaway Battery Be Mounted on It's Side
    If you are using a breakaway kit like the Hopkins Engager Trailer BreakAway Kit # 20099 that features a sealed battery in an enclosure then you can mount it sideways if that is a better mounting solution on your trailer. We do often see trailers with their breakaway battery installed in this way. If your kit does not use a sealed battery or if it does not have a protective case for the battery you might want to check the manufacturer's instructions for any cautions about how that particular...

  • Protecting a Trailer 7-Way Connector While Trailer is in Storage
    Covers for 7-Way trailer connectors are very uncommon and the only ones we have are attached to powered jacks. An inexpensive solution would be to use a small battery box such as # TK2051 and slightly modify it so you can put the 7-Way in it. I also recommend adding some dielectric grease, # LT37534, to repel moisture.

  • Universal Replacement Breakaway Battery Box for Trailer
    I do have an option for you but the replacement breakaway battery boxes that you were looking at like the Replacement Battery Box for Titan Gel Cell Breakaway Kit part # TN65117 are designed for specific breakaway batteries. Therefore, a better option for you would be to purchase a matching breakaway battery and box, like part # TK2023 and part # TK2051. The Curt Battery Box for Breakaway Kits part # C52090 may work for you as it measures 5-7/8" long x 3-1/2" wide x 5-3/8" tall but again...

  • Replacement Battery Box Recommendation to Replace one on 1994 Model 9419 Featherlite Horse Trailer
    The battery that fits in box # TN65117 measures 3.54 inches long, 2.76 inches wide, and 3.93 inches tall. Including the terminals it is 4.17 inches tall. This would be a bit too small for you based on the dimensions you listed. Instead take a look at the Tekonsha Battery Box part # TK2051. This box has inside dimensions: 5-15/16" long x 3-1/8" wide x 5-1/2" tall which would fit your battery well. The mounting holes would be different but you could still mount the box on your trailer.

  • Needing a 2-3 Wire System that will Seperate the Turn Signals from Stop Signal
    I do have a part that will work for what you are needing, but the Hopkins Tail Light Converter Kit, part # HM48895, will not take a 2 wire signals and split it into a 3 wire signal. To split your 2 signals into 3 you will want to use the Tow Ready Vehicle to Vehicle Tail Light Converter, part # 118158. This will take your combined turn and stop wires and separate them into right turn, stop, and left turn wires. Please note that this converter does not work well with LED lights. Another...

  • Battery Box to Carry CA1240 Battery on Boat Trailer
    The CA1240 battery you have on your trailer measures 3.5 inches long, 4 inches tall, and 2-3/4 inches wide which is a common size for a breakaway battery (most likely this is what the battery is for), so for a box to hold it the part # TK2051 would work well.

  • Can a Breakaway Battery Be Used to Power an Interior Light
    Yes, you can use a breakaway battery to power the interior light on your enclosed trailer. However, these batteries typically only have a 5 amp hour rating so that is something to make note of. If you were to use an LED interior light like the Optronics LED RV Interior Light with Switch part # RVILL34 then you would not have any issues as it only draws .6 amps of power. With that being said, you will not need the Tekonsha Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger...

  • Battery Box for Breakaway Battery that Measures 7” L x 6.5” H x 3” W
    Your battery is quite a bit larger than most breakaway batteries so for a box you'd have to go a slightly different route with something like the part # DW03009 which has inner dimensions of 10-3/4 inches long, 7 inches wide, and 8-1/4 inches deep.

  • Battery Box for a 4-1/2 by 2-3/4 by 4-1/4 Inch Battery
    Yes, your battery will fit in Curt battery box # C52022. The box is 6" x 3-1/4" x 5-1/2" on the outside and the inside is only slightly smaller. Another option is # TK2051. On the inside it measures 5-15/16" long x 3-1/8" wide x 5-1/2" tall.

  • What are the Dimensions of the Converter Box in Vehicle to Vehicle Tail Light Converter 118158
    We have a converter # 118158 laying around so I measured it. The box measures 2-15/16 inches by 2-7/16 inches by 1 inch. You could use a small battery box such as # TK2051 to better protect the converter from the elements. The converter will generate some heat so the box you put it in will need to be larger than the converter and it will have to have some ventilation. The battery box is the perfect combination of size and ventilation.
