12v Deep cycle VS SMF Battery

Table of Contents

What Is a Deep Cycle Battery?

Deep cycle batteries are designed to handle states of deep discharge, or depth of discharge (DoD), which is how much of the battery capacity is used in one full discharge of the battery. There are different types of deep cycle batteries.

Flooded deep cycle batteries will require the user to refill the electrolyte levels to maintain the battery, while sealed lead-acid batteries are a type of deep cycle battery that requires little maintenance and are spill-proof. This quality makes deep cycle batteries a good choice for recreational vehicles that may experience a lot of bumps and vibrations.

How Does a Deep Cycle Battery Work?

Deep cycle batteries have thicker lead plates compared to traditional lead-acid batteries, allowing the battery to provide longer sustained amounts of electricity but less power compared to traditional batteries. These batteries can withstand 80% or higher DoD, although the lifespan of the battery will benefit from keeping the DoD above 50%.

Characteristics of 12V Deep Cycle Batteries

Some unique characteristics they have included:

High capacity: The high capacity, which is stored within 12V deep cycle batteries, enables them to be able to deliver power to devices for considerable amounts of time.

Deep discharge capability: 12V deep cycle batteries can easily be discharged to a depth above 80% without any kind of damage caused to the battery.

Long cycle life: 12V deep cycle batteries are designed for hundreds if not thousands of charges as well as discharge cycles. Thus, this is good enough for applications that require the high-use frequency of the applied battery.

Ideal Applications: Deep cycle batteries are usually chosen for applications that need low but continuous power discharge, such as running appliances within an RV or keeping solar energy systems working.

Here is a table summarizing the key differences between 12V regular and 12V deep cycle batteries:

Characteristic 12V Regular Battery 12V Deep Cycle Battery
Lead plates Thinner Thicker
Reserve capacity Lower Higher
Cycle life Shorter Longer
Depth of discharge Less More
Applications Starting cars, running small appliances Powering RVs, boats, and solar systems

Characteristics of 12V SMF Batteries

These types of batteries consist of the following characteristics:

Voltage Output and Capacity: 12V regular batteries undergo an output voltage of 12V. However, their records have relatively fewer capabilities measured by ampere-hours (Ah), meaning they release large amounts of current within the shortest time possible.

Suitable Applications: 12V regular batteries are ideal for high-power applications in short durations. They do not cope well with long discharges and recharge cycles, though. Applications include powering smaller appliances like fans, radios, and lanterns, as well as starting motor vehicles, lawnmowers, and other small engines.

Can I use a deep-cycle battery for my car? Can I use a car battery for solar? Are they interchangeable?

What battery should you use for your car? Can I use the same for solar? Will one work in place of the other?

Choosing the right battery for your car or solar application is crucial because the wrong battery could not only provide insufficient power but also fail in extreme temperatures, resulting in unwanted costs and losses in productivity.

A conventional automobile battery and a deep-cycle battery are the two common types of batteries, and which one you choose will depend on its intended use and application. Although they both have a similar outer appearance, they differ internally in terms of operation and design.

Difference between a Regular Car Battery and a Deep-Cycle Battery

Both deep-cycle batteries and car batteries are lead-acid batteries that have the same basic elements and function in the same way. They have an electrolyte fluid, which is often acid, and negative and positive terminals. Simply explained, current flows between the negative and positive contacts with the help of the electrolyte fluid.

Internally, each type of battery has a different design. The strength of the electricity the battery will generate and how long it will take for the battery to drain are both influenced by the quantity of electrolyte fluid and the size of the metallic elements.

 

FAQ

What is in a lead-acid battery?

A lead-acid battery has a negative electrode made of spongy or porous lead and a positive electrode made of lead oxide. Both negative and positive electrodes are immersed in an electrolytic solution of sulphuric acid and water.

How do lead-acid batteries work?

Lead-acid batteries generate electricity through a double sulfate chemical reaction. Lead and lead dioxide on the negative and positive electrodes of a battery react with sulphuric acid in the electrolyte to form lead sulfate.

How long do lead-acid deep-cycle batteries last?

Both car batteries, as well as deep cycle batteries, are lead-acid batteries that function the same way. Generally, the lifespan of lead-acid deep cycle batteries is about four to eight years.

How can you tell when your car battery is going bad?

Some clear signs that your car battery is going bad include a slower-than-normal starting engine, a clicking or cranking sound when you turn the key, intermittent sparks that cause your car to backfire.

Are Marine Batteries Better Than Regular Batteries?

Marine batteries are not better or worse than car batteries, they are just meant to be used in two different applications and are built differently to accomplish that. The main purpose of a car battery is to provide power to the starter to crank the engine. Marine batteries are used for this purpose as well but are also used to power all of the electronic accessories on your boat and are designed to be used in the harshest conditions when out on your boat. They need to be able to withstand the bouncing, vibrations, and shaking that are common while out on the lake enjoying a day of watersports or fishing.

Marine batteries also come in different designs to suit your needs. Marine starting batteries are designed to provide that jolt of power to start your boat’s engine and then will recharge as you are out boating. If you need a workhorse battery that will start your boat and power the electronics, then the marine dual-purpose batteries are for you. For boats that have a lot of power demands, trolling motors, fish finders, etc. where just a starting or dual-purpose battery won’t be enough, marine deep-cycle batteries will provide the power you need to run all of those toys.

Can a deep-cycle battery be used for starting?

When considering the similarities of deep cycle battery vs cranking battery, it is often easy to assume that both batteries can partially function for the other. But that’s hardly the case, as many car users have come to find out and that’s one if the key points in the deep cycle vs starting battery comparison.

First of all, a deep-cycle battery may be able to function as a starter, depending on the car engine. However, it is highly unadvisable, as deep cycle batteries do not have the high cranking power required for this purpose. As a matter of fact, using a deep cycle battery as a starter will not only compromise the battery strength, and it cannot start the engine.

Deep cycle batteries are different to SLI or ISS batteries used in cars as they have:

  • Thicker grids and corresponding plates, which gives them longer life.
  • High density active material to increase capacity.
  • High percentage antimony in the positive grid alloy which improves cycling ability.
  • Separators made of rubber with a glass mat designed to retain active material and control water loss.

What is a starting battery?

A starting battery, or cranking battery as it is also called, is a rechargeable automotive battery that is designed to start a vehicle by providing a surge of high currents over a short period. It generally teams up with the alternator to ignite the engine, so each surge only takes about 3% of the battery power.

No doubt, the innovation of the starting battery has proved immense with lots of outstanding benefits and functions. In addition, when the generator is overloaded, the starting battery can assist the generator to supply power to the electric equipment, when the generator does not generate electricity or the voltage is low, the starting battery can also supply power to the electric equipment.

These actions don’t require the battery to stay active for too long. However, for the short period it will work, it provides maximum power that is enough to serve its purpose.
