Batteries come in all different sizes. Many have "group" sizes, which is based upon the physical size and terminal placement. It is NOT a measure of battery capacity. Typical BCI codes are group U1, 24, 27, and 31. Industrial batteries are usually designated by a part number such as "FS" for floor sweeper, or "GC" for golf cart. Many batteries follow no particular code, and are just manufacturers part numbers. Other standard size codes are 4D & 8D, large industrial batteries, commonly used in solar electric systems.

**Common Battery Sizes**

Some common battery size codes used are: (ratings are approximate)

U1 34 to 40 Amp hours 12 volts

Group 24 70-85 Amp hours 12 volts

Group 27 85-105 Amp hours 12 volts

Group 31 95-125 Amp hours 12 volts

4-D 180-215 Amp hours 12 volts

8-D 225-255 Amp hours 12 volts

Golf Cart & T-105 180 to 225 Amp hours 6 volts

L-16, L16HC etc. 340 to 415 Amp hours 6 volts
