12 Volt 31Ah to 42Ah Group U1 Batteries

Group U1 batteries are an extremely popular BCI group size. It can be overwhelming as you attempt to compare and decide what is the best brand and style for your application. Generally speaking these batteries will range between 31 amp hour (Ah) and 42Ah, 200 cold cranking amps (CCA) and 430 CCA and 30 reserve capacity (RC) and 50 RC. It depends on whether it is a thick plate deep cycle or thin plate stop/start battery or a dual purpose combination. The dimensions should be roughly 7.7 x 5.0 x 7.0 inches.

Most Common Group U1 Sealed AGM Battery Size: 12V 35Ah

The Group U1 family of batteries are often used in pairs with mobility scooters. Unlike the sealed AGM batteries used in scooters, powersport equipment and lawn tractors tend to use wet cell batteries. Although companies like MotoBatt no make a high cranking dual purpose AGM battery. The solar industry has come out with a taller version of the U1 that has 42Ah.

They have several variations of terminals including threaded internal, nut & bolt. The angle of the post can differ also. Overall, these differences will NOT hinder the ability to switch from one terminal type to another, but it is good to double check.
