Difference Between A Normal Lead-Acid Car Battery And A Deep Cycle Battery

 A Normal lead-acid car battery and a Deep cycle battery are two differently designed batteries that work for vehicles of different modes and capacities. The deep cycle batteries are designed for recreational vehicles (RVs), boats and machines of similar types. These batteries can be seen often in golf carts and large solar power systems. But, when it comes to the normal car batteries, they can be used as secondary batteries, or good for the low loaded engines.

Both car batteries and deep cycle batteries are lead-acid batteries work alike, but are far different from each other in dealing with the machines. Wondering how? Let us make it easy for you to understand.

Difference Between A Normal Lead-Acid Car Battery And A Deep Cycle Battery

In durability:

On comparing with any other car type battery, you can find that the Deep Cycle batteries live way longer. These batteries are designed in such a way that the maximum charge supply would be upto 80% only, while car batteries provide huge energy to start the machine of your vehicle at the initial stage itself. It means, the maximum of the charge consumption will be taking place at the start itself. Although, once the machine starts the alternator of the vehicle recharges the battery, but if any other devices of your vehicles need stable energy for a longer time, it will fail.

In such a way, the Deep Cycle battery by providing just the consistent power supply rather than a huge power as the starter, saves a lot of power compared to the car batteries. Thus, the durability of Deep Cycle batteries are high compared to the Car batteries.

In Discharge:

Like we discussed, A Deep cycle battery is designed to provide just a needed amount of current, covering over a long period of time of usage. So, the Best Deep cycle battery can be discharged again and again and charged for a number of times. Worrying about its efficiency?  Don’t! Because this battery has the thicker plates to accomplish the discharge and charge of the battery numerous times easily without any failure.

In Discharge

But, in case of the regular car batteries, they have thinner planes compared to the Deep cycle batteries which can’t handle the discharging of battery to the lower percentages. If it happens, it will directly impact the durability and efficiency of the car battery.

In simple words, a deep cycle battery can withstand hundreds of total discharge and recharge cycles, while a car battery is not at all designed to be totally discharged.

In ratings:

Generally, a battery has two ratings.

  1. Cold Cranking Amps: These are generally known as CCAs, which tells us the number of Amps a battery can produce at 0 degree Centigrade (32 degrees Fahrenheit) for half a minute (30 seconds).
  2. Reserve Capacity: This is generally known as RC,  which helps in knowing the number of minutes in which a battery can deliver 25 amps by keeping its voltage greater than 10.5 Volts.

On considering these two as the parameters, The Reserve Capacity of a Deep cycle battery is generally two to three times higher than the general car batteries. But, when it comes to the Cold Cranking Amps, It is a Car battery that delivers ½ or ¾ more CCAs compared to the Deep cycle battery.

In power:

We can say that the deep cycle battery holds more power than any of the normal car batteries. Ever observed the difference between a normal car and a race car? The speed variance and the smoothness of travel?

This difference is because of the harnesses of the power between these two batteries. A normal car battery provides short and high electricity pulses whereas a deep cycle battery releases a needed (lower), consistent amount of energy continuously, as it can always be discharged and recharged unlike a car battery. They are almost the same in design except the thickness of the electric plates surface area.

In short, both are useful and best for their own purposes. Both batteries can also be reconditioned easily. They are special in their own way and are invented based on the pulses an engine needs based on the mode of travel, usage. The leniency is a bit more towards the deep cycle battery due to its durability, discharge/charge ability and efficiency.
