Car Battery Charger vs Deep Cycle Battery Charger

We have talked in detail about the difference between deep cycle batteries and cranking batteries in other articles. Check them out if you haven’t already. But since we have talked so much about the different types of batteries available, it is only likely that their chargers will also differ. And they do. We will look at the different types of chargers after we look at the products. But till then, let us find out what happens exactly when you charge a battery.

We know that a battery stores electrical energy. Not all batteries are rechargeable. Those which are can be recharged by passing a suitable amount of current back into the battery. The chemicals react in presence of these charges and store the electrical energy that is passed into them.

The difference between normal chargers and deep cycle battery chargers is that normal chargers do not have to worry much about the amount of current passing through the battery. But heavy deep cycle batteries are very delicate and thus different strategies are used to charge them as efficiently as possible. We will talk more about these different properties in detail but first let’s have a look at the different chargers available for you in the market.

Types of Battery Chargers

We have discussed the different types of batteries available in the market in detail in a different article. To understand the different types of battery chargers in the market, first we need to understand the different types of batteries available to us. 

Different battery types have different chemistries and thus they react differently to different charging techniques. 

For this section, we’re just gonna assume that you are familiar with the basic battery types. With that assumption in mind, let us now discuss the different types of battery chargers available in the market for you to choose from. 

There’s a lot of things you must keep in mind before you actually go out and buy yourself a battery charger. We will talk more about them in detail in the next section. Until then, just know that the first thing you need to keep in mind before you can properly buy a battery charger is that you must always look for the right specification of the charger for your battery. Choosing a wrong kind of charger can destroy the charger, the battery or both.  

In this section, we will look at the most popular types of chargers available in the market nowadays. 

Standard Chargers

These types of chargers are very basic in nature. These chargers were one of the first type of chargers that were used with rechargeable batteries. They are still around these days and are fairly inexpensive and simple.

They are basically a simple electronic circuit that outputs a simple DC voltage or a pulsating DC voltage, depending on the type of the battery in question. Their simple construction and design make them fairly easy and cheap. However, they have their own drawbacks too. Since they pass a simple voltage without any sort of feedback, they do not have features like overvoltage protection etc. which we know to be very important and demanded feature in battery chargers. 

They can cause the batteries to get damaged in the long run and they must also be removed as soon as the charging is over or they can cause the batteries to get overcharged. This in urn can deteriorate the quality of the battery over repeated uses. In serious cases, the charger may even totally damage the battery and thus they are not an efficient solution. 

But you can look for a standard charger if you’re on a budget. They work just fine as far as the charging functionality is concerned.

Three Stage Chargers

These types of chargers are very popular these days. They are more advanced than the simple chargers we just discussed.

They basically take care of the charging process in three different steps. They moderate the amperage based on the feedback from the outputs and thus can efficiently maintain the battery and keep the battery safe. They can also make the battery stay charged when the charging is complete and do not require to be disconnected. 

In the first stage of the charging process, a huge current flows to the battery. This jolt of electricity removes sulfation and charges the battery up quite fast. Standard chargers often maintain a very low current for safety but the limitation does not exist with three stage chargers. Once the battery is rapidly charged upto a certain level, the internal resistance of the battery starts to act up. Fast charging at this stage can damage the battery by heating it up. Thus the charger moves on to the second stage. It decreases the amperage and starts charging the battery at a slower pace.

This goes on till the battery gets almost fully charged. At this point, further charging can damage the battery. Hence, the charger moves on to the third stage. At this stage, the charger outputs a very low and almost negligible amount of current which is just enough to compensate for the discharging of the battery that happens normally. 

This keeps the battery charge maintained at 100% thus increasing battery life. This type of chargers are widely used these days due to their simple functionality and high efficiency. 

Smart Chargers 

They are an emerging technology. Their working principle is very similar to that of the three stage charger, the only difference being that they implement more complex electronics to get a better understanding of the battery. Apart from simple charging, they can also monitor the exact status of the battery. Some chargers can also tell you the state of sulfation and charge concentration in the battery.   

Smart chargers can also be used as a power supply when required although this is a feature only seen in some products. 

Fast Chargers

As the name suggests, these type of chargers let you charge your battery in the fastest way possible. But did not we say that too high charging speeds can damage the battery? Well yes, they can. 

Fast chargers implement different calculations and find the optimal charging current for a given battery, some chargers even come with fans to keep the charger and the battery cooler. They are often paired up for use with regular Li-Ion batteries as they can support higher currents without experiencing any damage whatsoever. 

Fast chargers however, are not the best option all the time and you should really consider getting a proper charger to get a better battery life.
