The Group 34 Optima Battery REAR Mount is Artec Industries' vertical-surface solution for tucking a Group 34 Optima battery out of the way while keeping it laid flat. Instead of bolting down to a flat tray, this bracket fastens to any vertical panel — a firewall, inner fender, cargo-area wall, or a fabricated tray leg — and cradles the battery horizontally. It is a purpose-built answer for relocations and dual-battery builds where floor space is at a premium.
Key Features
- Rear-mounting design secures a Group 34 Optima battery to any vertical surface while holding the battery horizontal
- CNC-cut from 10GA (.130") cold-roll steel plate for a rigid, one-piece bracket
- Snug-fitting cradle eliminates the battery movement that causes premature wear and shortened life
- Self-clinching (PEM) nuts are pressed into the mount, so fasteners thread in without loose hardware behind the panel
- Open "window" lets you read the battery label and specs without pulling the battery
- Ships as bare steel — it must be painted, powder-coated, or otherwise sealed to prevent rust
Fitment & Compatibility
Universal fit. This mount is sized for the Group 34 Optima battery (RedTop/YellowTop 34 series) and is not vehicle-specific — it works on Jeep, Toyota, and truck builds alike as long as there is a suitable vertical surface to bolt to. Some adaptation may be required depending on your relocation location. If you prefer to mount the battery on a flat tray rather than a vertical wall, see the top-mount Group 34 Optima Battery Mount. For a standalone hardware set, pair it with the 4 Bolt Battery Mounting Kit.

Frequently Asked Questions
What vehicles does this rear mount fit?
It is universal. The bracket is built around the Group 34 Optima battery footprint rather than a specific chassis, so it can be mounted in any Jeep, Toyota, or truck build that has a flat vertical surface to bolt to. Some trimming or adaptation may be needed for a clean install.
How is this different from the standard Group 34 mount?
The standard mount bolts the battery down onto a flat, horizontal surface. This REAR version attaches to a vertical surface and holds the battery flat/horizontal off that wall, which is ideal when you have wall space but no floor space.
Does it come coated or painted?
No. It ships as bare cold-roll steel and must be painted, powder-coated, or sealed before use to prevent rust.
Do I need to weld it in?
No welding is required for the mount itself — it bolts to your chosen vertical surface using the pressed-in PEM nuts. You only need welding if you fabricate your own mounting surface or bracket to attach it to.
What battery does it hold?
It is designed for the Group 34 Optima battery. For other sizes, Artec offers Group 31, Group 51, and Group 25/35 versions.
