EDS Battery Terminal Kit — Positive 18mm & Negative 16mm Pair with M8 Studs, Tin-Plated Copper Alloy

If you need to replace worn or corroded battery clamps, the EDS 926-515 (positive) and 926-516 (negative) terminal set offers a direct-fit, heavy-duty alternative manufactured from tin-plated copper alloy. Designed to restore secure electrical contacts, this pair includes automotive-grade M8 nuts and studs for common Toyota and Lexus applications. The kit fits a wide range of model years and helps reestablish proper connection points when changing batteries or servicing the battery tray.

Which vehicles will these terminals fit?

This kit was made to cover many Toyota and Lexus models across multiple years. Fitment focuses on vehicles that originally used 18mm positive and 16mm negative terminal sizes and accept M8 stud hardware. Always compare the terminal dimensions and stud orientation with your vehicle before purchasing.

• Common Lexus models: GS350, GS450h, GX460, LX570, RX series (various years listed)
• Common Toyota models: 4Runner, Corolla, Highlander, Land Cruiser, RAV4, Sequoia, Tundra, Yaris
• Check your battery post diameter (18mm pos / 16mm neg) and stud location for exact compatibility

What materials and construction does this terminal set use?

The EDS terminals are formed from a copper alloy and finished with a tin (Sn) plate to resist corrosion and improve conductivity. The included M8 nuts and 8mm stud posts are automotive-grade, engineered to handle standard under-hood conditions. This construction balances conductivity with durability for routine automotive use.

• Copper-alloy body for solid electrical transfer
• Tin plating for oxidation resistance and easier torqueing
• M8 nuts and 8mm studs included for secure clamping

How do I install these battery terminals safely?

Installation is straightforward but should be done with the vehicle and accessories powered down. Remove the old terminals, clean the battery posts, slide on the new terminals, and tighten the M8 nuts to secure the studs and cable attachments. Use moderate torque—over-tightening can damage posts or deform the terminal.

• Disconnect negative cable first, then positive
• Clean battery posts before fitting for best contact
• Tighten nuts evenly; reattach cables and test electrical accessories

Will these terminals prevent future corrosion?

The tin plating helps reduce oxidation compared with bare metal terminals, and a snug mechanical connection reduces arcing that accelerates corrosion. While plating and good installation slow deterioration, periodic inspection and terminal protection products can extend life further. No terminal can fully eliminate environmental corrosion if exposed to salt or heavy moisture without additional protection.

• Tin plating lowers oxidation rate versus unplated alloys
• Tight, correct installation minimizes electrical resistance and arcing
• Recommended: apply protective spray or dielectric grease for harsher environments

Who is this for: The EDS 926-515 & 926-516 set is aimed at DIY mechanics, professional technicians, and vehicle owners who need a dependable replacement for worn battery clamps on many Toyota and Lexus models. If you are replacing a battery, troubleshooting poor starts, or refurbishing corroded terminals, this kit supplies the hardware and construction expected for routine automotive repair and maintenance.
