Battery Tray for Optima Batteries - Secure Billet Aluminum Mount

In this review the Battery Tray for Optima delivers a clear, focused solution for drivers who need a reliable trunk or race-mounted battery hold down. It is aimed at owners of Optima Red Top, Yellow Top and Blue Top sizes (34, 34R, 34/78, D34, D34/78, 34M, D34M) and anyone who wants a low-profile, durable relocation kit built from billet aluminum. The single biggest reason to buy is the combination of a sturdy base and heavy-duty hold-down hardware that keeps the battery stable during spirited driving or rough roads, while remaining compact enough for tight mounting locations.

Key Features

• Universal Compatibility: Fits most car and truck batteries and is specifically compatible with Optima Red, Yellow and Blue Top sizes for straightforward replacement or relocation.
• Secure Mounting: A solid base plate and top hold-down plates with three all-thread rods provide a secure clamp to prevent movement under vibration.
• Durable Construction: Machined from billet aluminum to resist impact and corrosion, offering long service life in exposed trunk or race environments.
• Customizable Fit: Includes thread sleeves for standard height batteries and accepts longer all-thread rods for batteries over 7.4 in tall to accommodate taller units.
• Complete Kit: Supplied with one base plate, one top plate, three all-thread hold-downs with nuts and three thread sleeves for a ready-to-install package.
• Compact Capacity: Supports batteries up to 10.5 in L x 6.95 in W x 6.7 in H with the included sleeves, making it suitable for a wide range of Optima formats.

Who It's For

This tray is best for automotive enthusiasts who relocate an Optima-style battery to a trunk, race bay or custom mounting point and need a reliable, low-profile mount that looks finished. Owners of performance cars, track-day vehicles and restomod projects will appreciate the billet finish and the secure three-point hold-down design.

It is less suited to buyers who expect integrated electrical hardware or a pre-threaded, captive fastener system; one reviewer noted the kit can come with hardware that needs attention during assembly. If you need a plastic or OEM-style tray with covered terminals, look elsewhere.
