Bought to replace old battery box cover that fell off while towing camper. Fit perfectly on top of old battery box. Just make sure it snaps in place before towing! Also comes with strap for additional security. 811812

Exactly what I was expecting. My previous battery box was for a larger battery, making connecting to the battery and getting the wires out of the openings a hassle because openings in the top didn't line up at all with the terminals. I use this for my small 14 ft Deep v fishing boat. 803457

Solid product, accurately described, really like the top snap feature. 785486

This is the one you want. I lost the top of my original battery box when the strap loosened up while towing. This box has the lid snap securely in place so it won't fly away if the strap gets loose without you knowing. Best price I could find was at etrailer and the shipping was reasonable and quick. 779253

Ask the Experts about this NOCO Battery Boxes

  • Battery Box To Mount On Flatbed Trailer
    We have battery cases that are used for either a breakaway battery that is too small for the dimensions of the battery you said you have, or battery boxes for larger batteries that may be too bit. One of the cases that you may want to check out is the NOCO, part # 329-HM300BKS. The inside dimensions for this box is 10-1/2 inches long x 7-3/16 inches wide x 9-5/8 inches deep.

  • Installing NOCO Battery Box
    The two mounting brackets included with the # 329-HM300BKS battery box would fasten to the mounting surface, using the included screws (or suitable hardware of your choosing) and the straps would be threaded through. The battery box would be placed on top of the straps, which would then be looped around the top of the box then buckled into place. Pretty easy, but I can understand why it wasn't obvious from the description photos.

  • How to Charge a Trailer Battery for Use with a Bulldog Jack
    What you described is actually the best solution! Connecting your battery to 12V Power wire from the 7-Way on your trailer is a great way to provide a maintenance charge on your battery to operate a Bulldog jack like part # BD500199. Mounting a battery inside a box like part # 329-HM300BKS inside your trailer will further help to keep your battery safe from the elements (although battery boxes do a pretty good job at that). Please note that the 12V power from your vehicle will not...

  • How to Mount 2 Batteries on A-Frame Trailer with Limited Space on Tongue
    I do have a possible solution for you but unfortunately there aren't any battery boxes available that will hold two 12V batteries and fit within a 21" length and 8" width. The closest thing we have is the TorkLift PowerArmor Locking Battery Box # TLA7708R which measures 26-3/4" long x 8-3/16" wide x 13" tall and as you can see from customer pictures the batteries fit in there pretty snug. Your batteries actually don't have to be side by side so you could potentially put one inside your...

  • Battery Box or Tray for a 7-1/2 x 5 x 7-1/4 Inch Battery
    NOCO Battery Box # 329-HM300BKS is a good option. The interior dimensions are 10-1/2" long x 7-3/16" wide x 9-5/8" deep. It doesn't have a metal bracket for mounting though. The boxes that have metal brackets are either too small for your battery size or they are custom made to fit specific vehicle frames. I would go with a box over a tray because a box will better protect the battery.

  • Adding a 7-Way, Battery, and Interior LED Lights for an Enclosed Trailer
    It would be a good idea to add a 7-Way trailer connector such as # 54-67-525 to the trailer so you can utilize the 12 volt circuit on the Toyota Tundra's 7-Way connector to provide a maintenance charge to a trailer mounted battery. On the above 7-Way the green wire is running lights, brown is right turn and brake lights, black is 12 volt that you will run to the battery on the trailer, red is left turn/brake lights, and white is ground. Usually on a 4-Way you will have white as ground,...
