What's the difference between F1 Terminals and F2 Terminals?
Faston 1 (F1) and Faston 2 (F2) are the type of connectors that are located on the top of the battery for quick installation. 
F1 terminals are .187 inches wide where the contact towards the end narrows; while F2 terminals are .250 inches wide where the contact towards the end narrows.
Most applications are interchangeable and connectors can be easily modified with pliers. We offer both as a convenience for the more discriminating customer.
