This universal 12-volt battery connector is the perfect solution for DIY enthusiasts, mechanics, and car owners who demand a clean, reliable, and flexible connection to power their vehicle’s electrical system. Whether you’re swapping in a fresh battery, installing a jump starter pack, or customizing an off-grid power setup, this connector provides a straightforward interface that you can adapt to your needs.

Key Features & Specifications

• Connector Dimensions: 1.42 inches wide x 2.20 inches tall — compact enough to tuck away yet easily identifiable when you need it.
• 5-inch Pre-attached Lead Wires: Generous length for routing flexibility under the hood or in a battery compartment. No more guessing if you have enough slack.
• Universal Compatibility: Fits most North American vehicles from 2016 and earlier that employ a standard 12V battery plug.
• Versatile Termination Options: Attach via butt connectors, wire nuts, soldering, or crimp terminals to create a secure, customized connection.
• Heavy-Duty Construction: Durable plastic housing with robust internal contacts for high conductivity and long-term resistance to vibration.
• Clearly Molded Polarity Markings: Prevents reverse connections by indicating + (positive) and – (negative) terminals.

Why This Connector Is Ideal for Your Vehicle

When you’re swapping batteries or adding power accessories, you want a connection that’s clean, safe, and won’t deteriorate over time. This connector’s streamlined design eliminates the guesswork:

• Easy Installation: With 5 inches of pre-wired leads, you’ll have the reach you need without stretching or forcing wires. Route them behind engine components, through trim panels, or down into a battery tray with ease.
• Customizable Termination: Whether you prefer quick crimp connectors for speed or solder and heat shrink tubing for the ultimate in durability, you can choose the method that suits your workshop style.
• Hassle-Free Replacement: Factory battery harnesses can fray, corrode, or break over time. Swapping to this connector means you’ll never be “stuck” under the hood with a bad plug again.
• Compact Profile: At just over 2 inches high, the connector won’t get in the way of other components or require a large mounting area. It tucks neatly against the battery housing or inner fender.
• Future-Proof Power Setup: If you upgrade to higher-capacity batteries, dual-battery systems, or auxiliary battery packs, this connector becomes a trusty hub for any 12V energy source.

Who Will Love This Connector?

Car Enthusiasts & DIY Mechanics: Keep your workshop running smoothly by using a standard interface across multiple vehicles. No more searching for the right harness when you’re juggling custom builds, restorations, or performance cars.

Off-Grid & Mobile Power Users: Perfect for campers, trailers, and vans equipped with solar chargers or power inverters. Quickly disconnect your battery for maintenance or to safeguard against power surges.

Installation Tips for a Rock-Solid Connection

• Always measure your existing connector before ordering. Confirm it matches 1.42" by 2.20" to ensure a snug fit.
• Strip only the prescribed amount of insulation (approximately 1/4 inch) to maintain maximum conductor surface area.
• Use high-quality crimp tools or soldering equipment to minimize signal resistance and prevent heat buildup.
• Seal all terminations with heat-shrink tubing or weatherproof butt connectors to guard against moisture and corrosion.
• Secure the connector housing with a zip tie or adhesive-backed mount pad to prevent stress on the leads.
