Can I use a deep cycle battery in my car?

I read online that a deep cycle battery is more powerful, which would be great. Can I use a deep cycle battery in my car without damaging the engine?

That’s a great question, but it may not be the best route.
While you can use a deep cycle battery in your car, it’s not well-suited. This is because it delivers half as much cold cranking amps as a generic car battery, meaning that its power is significantly reduced in cold weather.
What’s more, these batteries are designed to be drained and recharged without the help of an alternator. This can cause significant long-term damage to your car since you’ll be wearing out the battery by continually draining and recharging.
Using a deep cycle battery in your car offers no additional benefits to your vehicle. Instead,
is one of the best ways to upgrade your car.
