Buying Guide – How to Choose the Best Battery Relocation Kit
Choosing the right battery relocation kit depends on your vehicle type and performance needs. This guide explains key factors to consider.
Cable Gauge
The cable gauge determines how much current can flow safely. Lower numbers mean thicker wire which is better for high power needs. For standard cars 2 AWG is fine but performance vehicles may need 0 or 4 AWG.
Always check the gauge to ensure it matches your electrical demands. Thicker cables prevent voltage drops during high loads.
Cable Length
Measure the distance from your original battery location to the new spot. Kits offer lengths from 5 feet to 20 feet or more. Ensure you have enough length plus slack for routing around obstacles.
A cable that is too short requires extension which adds resistance. Plan your path before buying a kit with sufficient length.
Battery Box Material
Materials include plastic and aluminum. Plastic is lighter and cheaper but aluminum is more durable and looks better. For race or off road use aluminum provides better protection against impacts.
Choose aluminum if you need a box that lasts long. Plastic is fine for casual street cars.
Fitment
Check if the kit fits your specific vehicle or battery size. Universal kits work for many cars but custom ones offer better precision. Optima batteries need specific trays.
Verify dimensions before purchasing to ensure the battery fits securely. A tight fit prevents vibration damage.
Included Hardware
Some kits include all cables brackets and terminals. Others only include the box. Buying a complete kit saves time and extra costs.
Look for kits with all necessary parts. Missing items require extra shopping trips.
Warranty
A warranty protects against defects. Brands offering lifetime warranties show confidence. This is valuable for electrical components that see heavy use.
Check the warranty terms before buying. A good warranty adds value to the purchase.
Budget
Prices range from 20 to over 100 dollars. Budget kits may omit cables or use cheaper materials. Decide what you need most before spending.
Invest in quality if you need reliability. A cheap kit may fail under stress.
Installation
Some kits are bolt on while others require cutting. Check if you have the tools to install the kit. A plug and play design is easier.
Consider your mechanical skill level. Simple installs save time and frustration.
How to Use and Care for Your Battery Relocation Kit
Start by disconnecting the old battery negative terminal to avoid shocks. This ensures safety before you touch any electrical wires. Always wear gloves and eye protection.
Mount the new kit securely in the trunk or engine bay. Use all provided hardware to prevent movement. A loose battery can cause damage and dangerous failures.
Regularly check terminals for corrosion and clean with a wire brush. Tighten connections if needed. Proper care extends the life of your system and ensures reliable starts.
Frequently Asked Questions
Why relocate a battery?
Relocating a battery improves weight balance which helps handling. It also frees up space in the engine bay for larger components. Moving it to a cooler trunk location can also extend battery life.
Is relocation legal?
In many regions it is legal as long as the battery is secured properly. Always check local laws before moving a battery. Ensure the vent tube is routed safely outside the vehicle.
Do I need a relay?
Not always but for starter cables a relay may be needed if the distance is too long. Relays ensure the starter gets enough power. Check your vehicle manual before deciding.
Which cable size do I need?
For standard 12 volt systems 2 AWG is often enough. For high power audio or winches use 0 AWG. Match the cable to the highest current draw in your system.
How do I vent a battery?
Use a breather tube to vent gas out of the car. This prevents dangerous gas buildup in enclosed spaces. Most kits come with a tube for this purpose.
Can I move a lithium battery?
Yes but ensure the new location follows the manufacturer guidelines. Some lithium batteries have special requirements for temperature. Always check the manual before relocating a lithium pack.
How to keep wires safe?
Use protective conduit or loom for cables that pass through metal. Secure wires with zip ties to prevent chafing. Proper protection prevents shorts and keeps your system safe.
Final Thoughts on Choosing the Best Battery Relocation Kit
This guide covered ten top kits ranging from budget to premium. The Complete Aluminum Box kit stands out for value with included cables. The Joinfworld kit offers the best premium terminal option.
Prioritize cable gauge and fitment when making your choice. A secure box and proper wires ensure reliability and safety. Do not compromise on hardware quality for the sake of cost.
Prices change often so verify current details before buying. Check reviews for the latest feedback from users. Choose the kit that fits your build goals and budget today.
