Deep Cycle vs Normal Battery (Lead Acid Battery) Difference

A recreational vehicle known as RV’s and boat owners is very aware of deep cycle batteries. Massive Solar power systems and golf carts also use them as their power source. First, you need to understand the difference between Deep Cycle vs. Normal Battery (Lead-acid battery). Then you can understand the deep cycle battery procedure perfectly.

If you are not familiar, the solar power system is the system to acquire the power from the sun while it lights and store some of that energy and use it when needed. One or more deep cycle batteries powered inverters can be the alternative power source to gasoline generators.

Car batteries and deep cycle batteries use the same chemistry to operate because both are lead-acid batteries. The way of optimization of the batteries design is different.

Deep Cycle vs Normal Battery

Difference Between Deep Cycle vs Normal Battery

There are some significant differences between Deep Cycle vs. Normal Battery. We have found some key differences between Car Batteries vs. Deep Cycle batteries, and these two kinds also have significant differences. Especially a car battery can deliver a tremendous amount of energy in a short period. On the other hand, discharge applies the maximum amount of its capacity. Let’s find out more below.

Difference no. 1

A car battery is engineered to deliver massive energy for a brief period. You will need this stream of energy to turn the motor or engine on when starting. After the engine has started, the alternator takes over the battery and supplies the car’s power.

can i use deep cycle battery for starting

The company designed the deep cycle battery to deliver a constant amount of energy for a more extended period. So, a deep cycle battery delivers energy when the engine needs it, but it cannot deliver the stream like a car battery.

Difference no. 2

Deep cycle battery will frequently deeply discharge, applying the maximum capacity. A deep cycle battery discharges within 45% to 75% of its capacity. It usually lasts two or more years, but it can last over five years if the battery is with the right technology. Depends on the manufacturer.

If a standard lead-acid car battery or starting battery frequently discharges within 20% to 50% of its capacity, it will typically last 30 to 150 cycles. But if it discharges within 2% to 5% of its maximum capacity (what the manufacturer designed it for), it will deliver you thousands of cycles. A car battery cannot serve you as a deep cycle battery.

Difference no. 3

normal battery

A standard car battery or starting battery is usually engineered to start the internal ignition. You will more likely find thinner lead grids and sometimes lead sponges (looks like a foam sponge) in an average lead-acid car battery.

On the other hand, deep cycle batteries are used to run a trolling motor for an entire hour or more. Deep cycle batteries use thicker solid lead grids, not anywhere near sponges.

Difference no. 4

Cold Cranking Amps (CCA) measure the amount of energy that can deliver by a battery without descending to a specific standard cutoff voltage (which is usually 10.5 V) for 30 seconds at an absolute zero degrees Fahrenheit temperature. A cranking amp produced by a battery varies with the temperature. A battery produces more cranking amps when it is warmer.

A deep cycle battery can deliver almost the same or a bit less CCA than a car battery. So, while understanding the difference between Deep Cycle and Normal Battery, you should consider the CCA with importance.

Difference no. 5

Reserve capacity (RC) is the number of minutes a battery can supply 25 amps without descending the standard cutoff voltage.

According to – dcbattery.com– “Reserve capacity is the number of minutes a battery can maintain a useful voltage under a 25-ampere discharge. The higher the minute rating, the greater the battery’s ability to run lights, pumps, inverters, and electronics for a longer period before recharging is necessary. The 25 Amp. Reserve Capacity Rating is more realistic than Amp-Hour or CCA as a measurement of capacity for deep cycle service.”

 

So, we can easily say the superior in RC of a deep cycle battery vs. an average battery with lead-acid. A deep cycle battery’s RC will be two or three times more than a car winching deep cycle battery’s RC.

Difference no. 6

A deep cycle battery can resist a few hundred the total recharge/discharge cycle. But a car battery is not engineered to total discharge at all. If we see the features of the deep cycle batteries like VMAX MR127 Battery, Exide Edge FP-AGM24DP, and other trolling motor batteries, almost all the best kayak trolling batteries have this function.

Conclusion

The car and deep cycle batteries are made for totally different types of service. You won’t be comfortable using deep cycle batteries for starting issues as you will be with car batteries. After this thorough discussion on “Difference Between Deep Cycle vs Normal Battery,” I hope we will understand the process quickly.

And car batteries won’t even serve you the lowest expectation if you want to install them in a trolling motor. So, you have to decide which battery you need according to your necessity.
