Buying Guide – How to Choose the Best Battery Relocation Kit
Choosing the right battery relocation kit involves checking materials compatibility and included parts.
Material Quality
Look for kits made from high quality aluminum or durable steel to ensure long term resistance to corrosion and physical damage. Premium kits use 6061 aluminum alloy which is strong and lightweight suitable for racing or heavy duty environments.
Prioritize materials that match your vehicle environment such as PVC protective coating for rust resistance.
Cable Inclusion
Decide if you need a full kit with cables or just a box. Full kits include 5 AWG or 2 AWG wires which saves time and ensures compatibility. Check the cable length to ensure it reaches your new battery location without tension.
Confirm the included cables match your electrical needs to avoid extra purchases later.
Battery Fitment
Ensure the kit accommodates your specific battery group size such as 24 34 or D34. Some kits are universal while others target specific models like Optima batteries. Measuring your battery dimensions before buying prevents fit issues.
Choose a kit with adjustable mounts for flexible size adaptability to avoid custom modifications.
Mounting Hardware
A good kit includes all mounting hardware like wing nuts hold downs and brackets. Hardware like reinforced billet aluminum base and all-thread rods ensures secure placement. Anti-vibration hardware is essential for off road or racing applications.
Verify that all hardwares are included so you do not need to buy extra parts.
Breather System
For sealed boxes look for a breather fitting and tube to allow gas escape safely. This feature helps maintain battery health and prevents pressure buildup which can be dangerous. Not all kits include this so check the product details.
Select kits with integrated breather systems for safer battery operation in enclosed spaces.
Installation Ease
Choose kits designed for bolt-on or plug and play installation. Look for features like wing nuts and grommets which simplify the process for beginners. Avoid complex kits that require welding or custom fabrication if you prefer DIY.
Prioritize designs that require minimal tools and modifications for quick setup.
Warranty and Support
Check if the manufacturer offers a warranty such as a life time warranty for cables. Products made in the USA often come with better support and quality guarantees. Good customer service can help solve installation or fit issues.
Pick kits with clear warranty terms to ensure protection against defects.
Price vs Value
Compare the price against what is included. A higher price might cover a box and cables while a lower price might be box only. Assess your budget and needs to determine the best value without overspending.
Balance your budget against the components needed to ensure a complete safe solution.
How to Use and Care for Your Battery Relocation Kit
Start by disconnecting the negative terminal of your existing battery to ensure safety. Remove the old battery and measure the space where you plan to install the new kit to confirm fitment.
Securely mount the kit in the trunk or cabin using all included hardware like hold downs and brackets. Ensure the battery is tight to avoid vibration damage during driving.
Connect the provided cables to the battery terminals and secure them with heat shrink or terminals. Check all connections for tightness and verify the breather tube if included is properly routed.
