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

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 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 normal car batteries, they can as secondary batteries, or good for low-loaded engines.

Both Lead-Acid Car Battery and deep cycle batteries are lead-acid batteries that 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 up to 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, if any other devices of your vehicle need stable energy for a longer time, it will fail.

In such a way, the Deep Cycle battery by providing just a consistent power supply rather than a huge power as the starter, saves a lot of power compared to the Lead-Acid Car Battery. Thus, the durability of deep-cycle batteries is high compared to Car batteries.

In Discharge:

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

In Discharge

But, in the case of the regular car batteries, they have thinner planes compared to the Deep cycle batteries which can’t handle the discharging of the 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 tell 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 and recharged, unlike a car battery.

They are almost the same in design except for the thickness of the electric plates’ surface area.

In short, both are useful and best for their own purposes. Both batteries can also easily.

They are special in their own way and based on the pulses an engine needs

based on the mode of travel, and usage.

The leniency is a bit more towards the deep cycle battery due to its durability, discharge/charge ability, and efficiency.
