What are the things that connect to the car battery?

There are two cables that connect to your battery. The positive cable’s end connector is often either painted red or has a red plastic clip attached to it. It runs to the engine’s alternator.

Can I move my car battery to the trunk?

You can get all of the benefits of setting the engine back by simply relocating the battery from the front of the engine compartment to the trunk. This simple mod can change the weight distribution of a car from 1 to 2 percent.

Why put the battery in the trunk?

Because the engine is typically under the hood, cars naturally have more weight on the front wheels than on the rear wheels, and moving the battery under the trunk is a way to combat this uneven weight distribution.
