This small lead-acid battery is the "traditional" size for FF, CFF, and FC.  Its compact size makes it easy to mount in most formula cars, and its amp-hour rating is just right for most carbureted cars running a total-loss electrical system.  Since the capacity of this battery is fairly low, a booster battery should be used whenever possible when starting the engine.

Note that the dimensions are quite close to the Varley Red Top 25, although the Varley has much higher cranking amperage than this battery. 
These batteries are considered non-hazardous freight and can be shipped by air or ground.
