The Benefits of Moving Your Battery to the Trunk
You might not realize it, but the location of your car's battery can have an impact on how your car handles. That's because the weight distribution over the axles is crucial to a car's handling; the closer to 50% / 50% that distribution is, the better the car will handle.
One way to help move some of the weight to the rear of the car is by relocating the battery to the trunk. This may seem like a daunting task, but it's actually quite simple and can have an impact on your car's performance. Plus, it's a great way to extend the life of your battery. Here's everything you need to know about moving your battery to the trunk.
Why Move Your Battery to the Trunk?
There are several reasons why you might want to consider moving your battery to the trunk. First and foremost, as we mentioned, it can help improve your car's handling by evening out the weight distribution over the axles.
In addition, moving your battery to the trunk can also help extend its life. That's because engine heat and hot days sitting in the sun can cause batteries to fail after just 1-2 years.

Finally, another benefit of moving your battery to the trunk is that it frees up space under the hood. This can be particularly helpful if you're someone who likes to tinker with their car or make upgrades; you'll have more room to work without having to worry about coming into contact with an exposed battery.
