The car battery is very crucial to the car’s operating system. They prove to be the heart and soul of the vehicle, as they provide the starting power needed for your vehicle. They also provide energy for short-term uses like the lights. The replacement of such an important device with the wrong one could fry your automobile devices. Some might replace them with the same version and model, but when no such option is viable, you should use what is available. Some of these options include using a marine battery, but can you use a marine battery in a car? Let us find out.
Also known as boat batteries, marine batteries not only crank the engine but also supply energy for your boat’s electrical features, i.e., the boat’s lighting, sound system, and pumps. They function both as starting batteries and as deep-cycle batteries.
These batteries feature in many water vessels that need a steady flow of energy over long periods.
What is a Car Battery?
It is a rechargeable battery used to start and crank a motor vehicle. It provides power to the electrical motor that, in turn, triggers the chemically driven internal combustion engine that facilitates the vehicle’s propulsion. The battery also provides electrical power to the car’s electrical components, i.e., the brake lights, headlights, and instrument panel.
Differences Between a Marine Battery and a Car Battery
Car and marine batteries tend to look the same from the outside, yet they each have specific in-built mechanisms to help in their operations. It is essential to understand the critical differences between the two batteries that can significantly impact their utility. Their differences include:
1. Different task:
Although marine batteries also start the engines, they perform more diverse and extreme tasks. They do both starting and running work, as they continue to provide power for more extended periods after starting. They are responsible for powering the lights, gauges, and pumps at all times.
2. Their plate construction:
Car batteries have thin lead plates, which enable quick reaction time, thus enabling them to provide bursts of high amperage needed to crank the engine. In contrast, the marine battery has thicker plates that allow for a longer reaction time, enabling continuous production of power required to run the electrical accessories.
3. Robust construction:
Marine batteries have larger housings than the equivalent car batteries. Marine batteries have extra plastic protection due to the rough riding conditions. However, the car batteries have less plastic protection as road-driving conditions are smooth, thus less mechanical protection.
4. The rating method:
So, Can I Use a Marine Battery Instead of a Car Battery?
Yes, you can use a marine battery instead of a car battery, though they are not a viable option for use in cars. If you only need the marine battery to crank your engine, then the marine battery will provide sufficient cranking power. However, you need to check the marine voltage; if it is 12 volts, you can use it on your car, but if it is higher, it will fry your fuses.
Marine batteries should not power cars for long periods, as vehicles do not need a lot of deep cycle power. Continuous use of marine batteries would probably shorten the life span of your car’s electrical components, which might be expensive to replace.
Factors to Consider When Buying a Car Battery
Battery performance is an essential factor in determining a car’s abilities. Things to check when purchasing a car battery are crucial and very effective. Some factors to consider during the purchase are:
- Battery group size: This is the overall dimensions of a battery. Standard letters and numbers identify the different group sizes and depend on the vehicle’s model and make.
- Reserve capacity: this refers to the ability of fully charged batteries to keep providing power for the car’s accessories if the recharge sequence does not happen.
- Rating: Car battery rating is the CCA rating of a battery. It defines how well a battery can start a vehicle in cold conditions below 0°F. Higher CCA means higher cranking power.
- Battery freshness: This is a code used to indicate the date of manufacture. Six months is the timeline in which the battery may become faulty. If its manufacture date is earlier than six months, it is recommended not to purchase it.
- Guarantee period: It is advisable to choose batteries with long periods of free replacements and fixing warranties.
- Previous experience: Use your friends or your previous personal experience to determine the suitable battery.
FAQs
Is it OK to use a deep cycle battery in my car?
Deep-cycle batteries are not for use in vehicles. Although designed to discharge to much deeper levels, they do not produce as much cold current as a regular car battery.
Will marine terminals work on a car?
Is there a difference between deep cycle and marine battery?
Not all marine batteries are deep cycle batteries, as some marine batteries are only designed for starting and running boats. Thus, yes, there is a difference between the two.
Can an alternator charge a deep cycle battery?
Yes, they may, but most do not adequately charge deep cycle batteries as an alternator cannot compare to a charger.
Can you jump-start a marine battery?
Yes, you can, as many marine batteries are starting batteries; thus, no problem. Frequent jump-starting can destroy the battery life; therefore, consider replacing it.
Final Thoughts
Choosing the correct battery can prove to be a challenging task. Whether the battery is for boat or car use, ensure you know the specs and factors, as high performance is greatly needed. Sometimes you might need to incorporate different batteries for better performance, but without the crucial facts, you may end up ruining the car.
