Antigravity Top Post to Side Terminal Adapters

Antigravity Top Post to Side Terminal Battery Adapters | Pair

Convert standard top post automotive batteries to side-terminal connections using Antigravity Top Post to Side Terminal Adapters. Durable, high-conductivity fit.

Upgrade or convert your battery setup seamlessly with Antigravity Top Post to Side Terminal Adapters. Engineered for vehicles requiring side-terminal battery cables, these heavy-duty brass/metal adapters clamp directly onto standard top-post battery terminals (SAE posts) and convert them into threaded side-terminal mounting points. They allow you to install modern lightweight lithium batteries—such as Antigravity AG-35, AG-24, or AG-48 series—or standard top-post AGM/lead-acid batteries into vehicles factory-equipped with GM-style side-mount battery connections without modifying or cutting your existing wiring harness.

Best Uses

1. GM Vehicle Conversions: Perfect for classic and modern General Motors cars, trucks, and SUVs built with factory side-terminal battery cables.
2. Lithium Battery Upgrades: Installing Antigravity top-post lithium batteries into vehicles with side-mount cable connections.
3. Custom Automotive Builds: Hot rods, restomods, and race cars requiring custom cable routing or tight battery tray clearances.
4. Universal Applications: Adapting standard SAE top-post batteries for marine, RV, or secondary battery bank installations that use side-mount connections.

Features

1. Direct Clamping Mechanism: Secures firmly over positive and negative SAE top posts using integrated clamping bolts.
2. Standard Side-Thread Receiver: Fits standard 3/8"-16 side-terminal battery bolts used in factory vehicle harnesses.
3. High-Conductivity Construction: Premium solid metal construction ensures maximum current flow and minimal voltage drop during engine cranking.
4. Color/Polarity Markings: Clearly defined positive and negative sizing to ensure proper post fitment and prevent accidental reverse polarity.
5. Compact Low-Profile Design: Minimizes added height and lateral space requirements in tight engine bays and battery trays.

Benefits

1. No Cable Cutting Required: Retains original factory battery cables without cutting, splicing, or installing new cable ends.
2. Expanded Battery Selection: Unlocks the ability to use a wider range of top-post lithium or AGM batteries in side-terminal-only vehicles.
3. Optimal Cranking Power: Solid metal contact delivers reliable starting power for high-compression engines.
4. Easy Plug-and-Play Installation: Fast, straightforward installation using basic hand tools in just a few minutes.
5. Corrosion-Resistant Finish: Built to withstand harsh engine bay environments, moisture, and chemical exposure for long-lasting reliability.
