Each battery has a different purpose. There are separate industry measurements for each battery.
Engineers measure the power created by a typical car battery in “Cold Cranking Amps”. Cold Cranking Amps is the measurement of how much current a charged battery can provide. Usually, they measure the current over a period of 30 seconds. The battery should maintain a voltage of 7.2 volts (12-volt battery) under conditions of -18°C for the test.
Cold Cranking Amps measure short bursts of electricity. Yet it does not record power consistency over a long period of time.
A measurement used for deep cycle batteries is it’s Reserve Capacity. It is a measure of minutes that a battery can deliver 25 amps at 80ºF and maintain a terminal voltage of 1.75+ volts per cell.
A deep cycle battery may produce only one half of the Cold Cranking Amps that a car battery will. Whereas it will have 2-3 times the Reserve Capacity.
Each is powerful but apply its electrical charge in a different way according to its purpose.
Are These Batteries Interchangeable?
As they have the same elements, technically a user could interchange these batteries. Yet, this is not recommended. The design of the regular car battery is more suited to shorter use. its metal platings are not designed for ongoing use. In fact, they can warp after a short time at such high power.
The design of Deep-cycle batteries, as the name suggests, is more suited to deeper more regular use. Often users will run the battery to exhaustion.
In the year 2019 is there a battery that can act as both a deep cycle and normal car battery? Yes. Inventors have created a dual-purpose battery. This can provide both short term bursts of power and longer lower-level power.
Does this spell the end of these types of battery? Not soon. The physical design of the two battery types is too different. A single design that is able to function efficiently in both batteries is not possible.
It is still recommended to buy either a regular battery or deep cycle battery type. This way you are purchasing a battery that will provide the power you need.
How to Choose the Right Battery for Your Needs?
Whether deep cycle or a regular type, a well-chosen battery is crucial to your business. It can mean the difference between success and failure. The longevity of your machinery or its quick degradation due to incorrect powering.
