Group U1 Battery Box Description

All standard group U1 batteries are the same size. The dimensions are 7-3/4″L x 5-3/16″W x 7-5/16″H. Our group U1 battery box is made to fit batteries that measure up to 8-3/16″L x 5-1/2″W x 7-3/8″H. Please measure your battery before ordering to make sure it will fit.

This battery box is designed to fit group U1 auto, marine, and RV lead-acid batteries. This rugged battery box is impact-resistant and will give years of great protection for your battery. All of our battery box covers have built-in vent channels to allow battery gases to escape.

Our group U1 battery box is made of heavy-duty polypropylene, an acid-proof plastic resin. Further, it is not harmed by battery acid, oil, gasoline, and other harsh liquids. This box includes a hold-down strap and a mounting hardware kit. All of our battery boxes are made in the USA at our factory in Ohio.

Other Battery Box Models

We also make other battery boxes that will fit 6-volt, group 24, and group 27 batteries. In addition, we also have a large adjustable battery box that will fit more than one size battery. This lets you switch to a different battery without the need to replace the battery box. It will fit any group 24, group 27, group 29, or group 31 battery. To keep the battery positioned toward one end of the box, just place the plastic panel into the slot closest to the battery. The extra space in the box can then be used to store small tools or other items. Just place them in a plastic bag first to protect them before you put them in the box. Also, each battery box model we sell includes a protective cover with integrated cable slots.
