Stinger SPT53303 PRO Series Negative Battery Terminal with 2x 0GA and 1x 4GA Ring Terminal Outputs Shoc-Krome Chrome Finish and Clear Perspex Cover
The SPT53303 from Stinger is a PRO series negative battery terminal in Shoc-Krome chrome finish, providing two 0 gauge and one 4 gauge output ports that accept standard 5/16 inch ring terminals. A precision allen key screw ensures a tight, secure fit on the battery post. A clear Perspex cover is included. This terminal is the negative counterpart to the SPT53103 positive battery terminal.
Product overview
The SPT53303 provides stud-style output ports that accept standard 5/16 inch ring terminals, allowing cables pre-terminated with ring terminals to connect cleanly at the battery negative post without stacking multiple ring terminals on the factory battery stud. Two 0 gauge ports and one 4 gauge port provide a total of three output connection points across two cable gauges, suited to high-powered car audio systems where multiple large gauge ground runs need to terminate at the battery negative post.
The precision allen key screw on the battery clamp provides a tight, secure connection to the battery post, and the Shoc-Krome corrosion-resistant chrome finish maintains the terminal's appearance and conductivity in the engine bay environment. The clear Perspex cover protects the ring terminal connections from accidental contact and debris. The SPT53303 shares the same port configuration and design as the SPT53103 positive terminal, providing a matched negative counterpart for complete positive and negative battery terminal installations.

Frequently asked questions
How does the SPT53303 differ from the SPT53302?
The SPT53302 uses set screw ports that accept bare wire ends directly, covering one 0 gauge, one 4 gauge, and two 8 gauge connections. The SPT53303 uses stud-style output ports that accept pre-terminated 5/16 inch ring terminals, covering two 0 gauge and one 4 gauge connections. The SPT53303 is the better choice when cables are already terminated with ring terminals and a clean, serviceable battery connection point is needed.
Does the SPT53303 pair with the SPT53103 positive terminal?
Yes. The SPT53303 shares the same port configuration (2x 0GA, 1x 4GA ring terminal outputs) and Shoc-Krome chrome finish as the SPT53103 positive terminal, providing a matched positive and negative battery terminal set when both are used together.
Can the SPT53303 be used as a positive battery terminal?
No. The SPT53303 is confirmed for use as a negative battery terminal only. For a matching positive terminal with the same port configuration, the SPT53103 is the correct product.
What ring terminal size does the SPT53303 accept?
The SPT53303 accepts standard 5/16 inch ring terminals across all output ports, compatible with the Stinger SPT5101, SPT5104, and SPT5108 PRO series ring terminal packs listed in this session.
What does the clear Perspex cover do?
The clear Perspex cover protects the ring terminal connections and output ports from accidental contact with metal objects in the engine bay and shields the connection points from debris and moisture, contributing to long-term reliability and safety.
