CURT 52022 6-Inch x 5-1/2-Inch x 3-1/4-Inch Lockable Trailer Breakaway Battery Case

I really like this little container, though I don't use it for a battery. I needed something in my boat to hold my documents for when I get checked by the Water Patrol. Needless to say, you don't have a lot of space in boats and you want to take advantage of all the room you have. I was able to mount this box without taking up a lot of room. And because it is compact, I was able to place it in a not highly exposed area. I like the fact that it is lockable, and from what I can tell, almost completely waterproof. I can't say for sure because I haven't had it out during a really hard rain. I keep my documents in a zip lock plastic bag anyway, so it really doesn't matter to me. All in all, a great price and I can recommend this if you need a small lockable box. Not sure how it would be for batteries.

Good materials well made

Battery fit is a tight one. Not as good as the other model

It's just what you'd expect.

I was hoping that this battery box would fit the 10.5 AH sealed battery as the dimensions should allow this, but there is a slight tapper to the box disallowing this type of battery to be used. ( this is very common battery type found in UPS systems, mobile cart, emergency lighting etc ) there are some plastic molded in tabs I assume accommodate battery XYZ perferctely , but after going to specialty battery store the best that I could do was a square 5 AH battery ( like the UB1250 ) while this does fit there is still some slop and I would not call this a perfect fit. ( no modifications of the box was necessary ) to remove the tabs on the side should be fairly straight forward but the bottom could be an issue ( its kind of small area to work in ) there is room in the box for cables and maybe a small trickle charger with a 5 AH battery.PRO'sthe mounting area seems beefy enough to mount and not worry about loosing this thing on the roadthe lid is snug and snaps in place ( even with out a lock I don't think this thing is going to open at highway speeds )the lock area has a large enough hole to use a real lock ( not the cheap luggage type )plastic is not the bakelite type and should be easy to modify (drill holes for additional / larger wires etc) and will stand up to a lot of abuse / road miles.What would have made this box over the top good.1) A few more centimeters to allow for a 10 AH battery ( if you warmed this thing up you may be able to make it work, and for 5 bucks I may try it... )2) Some way to tie a battery down ( either holes for a zip tie ) or a few molded plastic screw holes to put a strap on.3) Actually knowing what battery / charger combo was envisioned from the designers ( i'm sure they had a plan, maybe... )4) not a fan of the holes almost the middle on the sides would have been good so you could route a battery vent if you were not using a sealed battery. other wise no holes if it leaks I want it contained. also if you are mounting this on your trailer its just a way for dirt and crap to get in ( the problem is easily corrected with some silicone. ) if there were no holes i could have easily put them where I needed... ( this can't really be listed as a neg because 50% will want holes the other 50% no holes ) my application is inside of a tackroom for a light when the trailer is not hooked to the 12V on the truck so acid leaks are bad...

I had a mobile guy come replace the floor of my cargo trailer. He "lost" the battery and the mount. In that moment, I realize that I needed a more secure way to hold (and lock) my trailer brake battery. I found this and it was ABSOLUTELY perfect! Secure and able to lock it. I had to make a couple modifications to meet the trailer's needs, but it was easy to do with this unit.

These boxes are intended to house a breakaway battery and a little wiring on a trailer. They are weather resistant, have a sturdy latch, and mounting tabs for attaching to the trailer.I used these for something entirely different. I have a trailer wiring tester that is built into a plastic ammunition box. I wanted to add a charger and meters for voltage and current. I added two of these, one on each side of the test box. It worked very well.

Can't even get a small battery to fit. The size they state this box is don't believe. I should of read the reviews.
