Cannonfish Battery Terminal Connectors Pair — Red 18mm & Black 16mm with M8 Nuts for Easy Installation

Cannonfish battery terminal connectors are a two-piece positive (red) and negative (black) set designed to give a secure, easy-to-install connection for compatible Nissan, Infiniti, Toyota and Lexus batteries.

These Cannonfish battery terminals arrive as a matched pair with clear polarity coloring and molded protective housings. The set includes part 243407F000 (red positive housing, 18 mm / 0.71 in) and part 243407F001 (black negative housing, 16 mm / 0.63 in). Each connector is engineered for straightforward mounting with an M8 nut, and the plastic bottom shell protects the metal contact from accidental shorts and corrosion-prone exposure.

How do these terminals make installation simpler?

Installation is kept simple by color-coded housings and a built-in fastening system. The supplied M8 nuts mean you don’t need to source additional hardware, and the compact dimensions let the connectors slip over standard battery posts commonly found on the listed vehicle makes.

• Includes one M8 nut per terminal for immediate mounting
• Color-coded red (positive) and black (negative) for quick identification
• Formatted to fit 18 mm positive and 16 mm negative battery posts

What materials and protection features are included?

The connectors combine metal conductive surfaces with a rugged plastic bottom housing to balance electrical contact quality and physical protection. The plastic shell reduces the chance of accidental shorting and shields the metal from direct exposure to moisture and grime.

• Durable conductive metal contact for reliable current transfer
• Protective molded plastic bottom housing to resist impacts and debris
• Color-coded plastic covers to prevent polarity mistakes during service

Will these fit my vehicle and battery post sizes?

These Cannonfish connectors are specified for vehicles that commonly use 18 mm positive and 16 mm negative posts, and they are marketed for compatibility with Nissan, Infiniti, Toyota and Lexus models. Always verify post diameter on your battery before purchase to ensure a secure fit.

• Positive terminal: part 243407F000, red, 18 mm (0.71 in)
• Negative terminal: part 243407F001, black, 16 mm (0.63 in)
• Commonly compatible with Nissan, Infiniti, Toyota, Lexus battery posts

How do I maintain and inspect these connectors for safety?

Routine visual checks and light cleaning will keep the terminals functioning well. Inspect the plastic housing for cracks and the metal contact for corrosion; replace if either shows significant wear. Tighten the M8 nuts to secure the connection, avoiding overtightening which can damage the housing or post.

• Check for corrosion on metal surfaces every few months
• Ensure M8 nuts remain snug but not over-torqued to prevent damage
• Replace if plastic housing is cracked or metal contact is excessively corroded

Who is this for: Car owners, mechanics and DIY enthusiasts who need a straightforward replacement battery terminal set for Nissan, Infiniti, Toyota or Lexus vehicles. This Cannonfish pair suits anyone wanting color-coded polarity, protective housings, and hardware-ready connectors sized to standard 18 mm/16 mm battery posts.
