Buying Guide – How to Choose the Best Battery Relocation Kit

Selecting the right battery relocation kit involves balancing material quality, cable specifications, and vehicle compatibility to ensure safety and performance.

Material Quality

The construction material determines durability and resistance to heat or moisture. Aluminum boxes are corrosion resistant and strong but can be heavier than plastic. Look for coated metals like PVC film for extra protection against rust.

Prioritize aluminum or reinforced iron components for long-term reliability in harsh environments.

Cable Gauge

Cable thickness matters for conducting high current safely. Common gauges include 0, 2, 4, and 5 AWG. Thicker cables like 0 AWG reduce resistance for high power applications like winches or amps.

Choose a gauge that matches your vehicle's electrical demand and the distance required for routing.

Battery Fitment

Ensure the kit accommodates your battery size and terminal type. Some kits are universal while others fit specific brands like Optima or specific groups like 24 or 34.

Verify dimensions and terminal style before purchasing to avoid compatibility issues.

Installation Ease

Look for bolt-on designs and included accessories like breather fittings and hold-downs. Plug and play kits save time compared to needing extra hardware.

Select kits with clear instructions and hardware to simplify the installation process.

Accessibility Features

Some kits include remote terminals or jump posts for convenient charging without opening the hood. This is useful for vehicles where the battery is moved to the trunk.

Consider if you need easy charging points and choose kits with remote terminals if so.

Safety Features

Waterproof caps, heat shrink tubes, and insulated boots protect connections from shorts and corrosion. These add to safety and longevity.

Ensure your kit includes protective caps or shrinkage to secure connections.

Brand Reputation

Known brands like JEGS or Joinfworld often provide better quality control and customer support. Read reviews to gauge reliability and warranty terms.

Prefer established brands with good ratings for consistent performance.

Cost vs. Package

A full kit with cables and box costs more but saves on buying parts separately. Basic kits may be cheaper but require additional purchases.

Calculate the total cost including any extra parts needed for your project.

How to Use and Care for Your Battery Relocation Kit

First disconnect the negative battery terminal before beginning any work to avoid electrical shorts. Clean the battery surfaces and ensure the new mounting location is secure and stable before installing the box.

Route the cables carefully away from hot engine parts and moving components to prevent wear or damage. Tighten terminals securely but do not over-tighten to avoid stripping threads on brass or copper posts.

Check connections periodically for corrosion and tighten them if necessary to maintain good conductivity. Use dielectric grease on terminals to extend their life against moisture and oxidation.

Frequently Asked Questions

Why relocate a battery?

Relocating a battery helps optimize weight distribution in a vehicle, improves performance and handling. It also protects the battery from engine heat and debris which extends its lifespan significantly.

What gauge cable do I need?

For standard automotive use 4 to 5 AWG is common. For high performance applications like winches or large audio systems choose 0 or 2 AWG to handle higher current safely without voltage drops.

Can I move the battery to the trunk?

Yes moving the battery to the trunk is a common practice to reduce weight under the hood. Ensure you use a battery box that is sealed and ventilated properly to prevent gas buildup.

Do kits come with cables?

Some kits include cables while others only provide the box. Always check product details carefully to see if wiring is included or if you need to purchase it separately.

How do I secure the battery?

Use hold-down brackets or anti-vibration hardware included with the kit to secure the battery. Never rely on the box alone; ensure the battery does not move during driving.

Do I need a breather tube?

Yes a breather tube vents dangerous gases away from the battery compartment. This is essential for lead acid batteries to prevent pressure buildup and improve safety in enclosed spaces.

What materials are best?

Aluminum is durable and rust-proof but can be heavy. High-density plastics are lighter but may not last as long in extreme heat or cold environments.

Will this void my warranty?

Installing a relocation kit may void warranty terms related to the electrical system. Check with your vehicle manufacturer before making major modifications to stay compliant.

Final Thoughts on Choosing the Best Battery Relocation Kit

These ten kits offer a range of solutions from universal boxes to specific Mustang fits. The Aluminum Complete Kit and JEGS Single Kit stand out for their balance of quality and affordability for most users.

Prioritize safety and fitment when choosing to avoid damage or poor electrical performance. Ensure your selected kit includes all necessary parts for your specific battery type and vehicle.
