The Power Sonic (035021) is a battery terminal adaptor. Specifically, it converts an F1 (0.187″) tab up to an F2 (0.250″) tab. First, it slides over a battery’s F1 spade post. Then, the receiving connector or wire lug attaches to the larger F2 tab end.
How the Power Sonic (035021) adaptor is used
Therefore, technicians use this adaptor when a replacement battery ships with F1 terminals. Specifically, it solves the case where the equipment harness expects F2 connectors. In addition, it lets service techs install a wider range of Power Sonic SLA batteries. As a result, no harness re-crimping is required. As a result, the 035021 simplifies field battery swaps where terminal sizes do not match.
