Battery for Generac Automatic Standby Generator and more

BCI Battery groups 24, 27, and 31 are some of the most popular battery groups, differing in size and thus their capacity, CCA/MCA, and other ratings.

Physical dimensions of these groups are given in the following list:

- Group 24: 10.25 x 6.8125 x 8.875 inches (260 x 173 x 225 mm),

- Group 27: 12.0625 x 6.8125 x 8.875 inches (306 x 173 x 225 mm),

- Group 31: 13 x 6.8125 x 9.4375 inches (330 x 173 x 240 mm).

As the size and the volume of the batteries go up, so do their Amps, Ah, and other values.

BCI Group 26R batteries are mostly general-purpose batteries commonly found in large UPS systems, medical and security systems, wheelchairs, car batteries, trucks, and industrial applications, etc. They are rarely used as starting/cranking batteries - more commonly they are used in deep cycle of standby/float applications.

Perfect Battery for your generator.
