The Group 31 Optima Battery Mount is a heavy-duty, one-piece hold-down for the large Group 31 (D31) Optima battery. Artec builds it to lock the battery down tight so it does not shift under hard trail articulation, hits, or highway vibration — the kind of movement that cracks cases and shortens battery life. It is a clean, bolt-in upgrade over flimsy factory clamps for any relocation or dual-battery setup.
Key Features
- CNC-cut from 10GA (.130") cold-roll steel plate in a rigid one-piece design
- Sized specifically for the larger Group 31 Optima battery so it fits snug and eliminates movement that causes premature wear
- Self-clinching (PEM) nuts are pressed into the mount for clean, captive fastener threads
- Open "window" lets you read the battery label and specs at a glance
- Includes six 1/4" bolts with nylock nuts to secure the battery
- Ships as bare steel — must be coated, painted, or powder-coated to prevent rust
Fitment & Compatibility
Universal fit. This mount is built around the Group 31 Optima battery and is not tied to a specific vehicle, so it suits Jeep, Toyota, and full-size truck builds wherever you can create a flat mounting surface. Some adaptation may be required for your particular location. Running a different battery? Artec also offers the Group 34, Group 51, and Group 25/35 Optima mounts.

Frequently Asked Questions
Which battery does this fit?
It is designed for the Group 31 (D31) Optima battery, the larger of the common Optima sizes. It is not sized for Group 34 or Group 25/35 batteries — use the matching Artec mount for those.
Is it vehicle-specific?
No. It is a universal mount built around the battery footprint. It bolts into Jeep, Toyota, and truck builds wherever you have or can build a flat surface; some adaptation may be required.
What hardware is included?
The mount has self-clinching PEM nuts already pressed in, and it ships with six 1/4" bolts and nylock nuts to strap the battery down.
Does it come finished?
No. It is bare cold-roll steel and needs paint, powder coat, or another sealer before installation to keep it from rusting.
Do I have to weld anything?
The mount bolts in and requires no welding on its own. Welding is only involved if you fabricate a custom surface or tray to bolt it to.
