Deep Cycle vs Normal Battery (Lead Acid Battery) Difference
A recreational vehicle which commonly known as RV’s and boat owners are very aware of deep cycle batteries. Huge Solar power systems and golf carts also use them as their source of power. 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 inverter can be the alternative power source to gasoline generators.
Car batteries and deep cycle batteries both use the same chemistry to operate because both are lead-acid batteries. The way of optimization of the batteries design is the difference.
Difference Between Deep Cycle vs Normal Battery
There are some significant differences between Deep Cycle vs Normal Battery. As we have found some key differences between Car Battery vs Deep Cycle battery, these two kinds also have significant differences. Especially a car battery can deliver a huge amount of energy in a short period. Where on the other hand, discharge applying the most maximum amount of its capacity. Let’s find out more below.
Difference no. 1
A car battery is engineered to deliver a huge amount of energy for a very short period. You will need this stream of energy to turn the motor or engine on when starting. After the engine has started the alternator take over the battery and supply all the power the car needs.
The company designed the deep cycle battery in a way that will deliver a constant amount of energy for a longer 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 most maximum amount of its capacity. A deep cycle battery discharges within 45% to 75% of its capacity. It usually lasts two or more years but if the battery is with right technology it can last over five years. Depends on the manufacturer.
If a normal lead-acid car battery or starting battery, frequently discharges within 20% to 50% of its capacity, it will normally 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 deep cycle battery.
Difference no. 3
A normal car battery or starting battery is usually engineered to start the internal ignition. You will more likely find thinner lead grids and sometimes lead sponge (looks like a foam sponge) in a normal 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 sponge.
Difference no. 4
Cold Cranking Amps (CCA) is the measure of the amount of energy can deliver by a battery without descending to a certain standard cutoff voltage (which is normally 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 same or a bit less CCA than a car battery. So, while understanding the difference of Deep Cycle vs 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 certain 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 a normal 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 few hundreds of 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 battery, almost all the best quality batteries have this function.
The car batteries 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 easily.
And car batteries won’t even serve you lowest expectation if you want to install it in a trolling motor. So, you have to decide, which battery you need according to your necessity.
