A number of people decide to use deep cycle batteries in their vehicles because they are able to discharge to the point of using most of its capacity, unlike traditional starter batteries which fire off higher currencies and use only a small percentage of its actual capacity. While it is true that deep cycle batteries can be helpful because of the extra discharge, they are not always necessary depending on the vehicle itself. Getting the right charger is certainly an important aspect of having one of these batteries in a vehicle because there are times where its energy will need to be renewed as quickly and efficiently as possible.
One of the most important issues to address when searching for the right charger for a deep cycle battery is the time it takes to fully recharge it. A 10 amp deep cycle charger which is used with a 100 amp/hour battery will be able to fully charge it within approximately 11 hours. One very important thing to consider when trying to get the best charger for a deep cycle battery is the amp hour rating of the battery that you have, dividing that number by the overall charger rating in amps, then adding around ten percent to the total time it would take to fully charge the battery.
What a number of people overlook is the extra time it takes to fully power up a completely discharged battery, which is why it is crucial to add on the extra 10% to the time which you have calculated it will take given the amp hour rating of the battery and the total number of amps the charger has. There are some important differences between a traditional cranking battery and a deep cycle batter as far as charging is concerned. Typically with the latter you will have to account for even more time to charge the battery so it is at full power because of the larger capacity these batteries have.
The charger that you select for one of these batteries will depend on numerous things, including the design of the battery itself. Before spending any money on a charger, it will be important to establish which type of battery you have and the specific construction of it. Since there is no universal charger for these batteries, it is important to look into the specifics of what you have. There are four different types of deep cycle batteries, including gel cell, wet cell, absorbed glass mat, and the lead-acid type (VRLA).
A majority of people already know about wet cell batteries and are rather familiar with them. Wet cell batteries are available in most auto parts stores and can easily be found, so locating a charger for one should not be a difficult task at all. There are three different types of deep cycle batteries that can be used with a multiple stage charger, including wet cell, absorbed glass mat, and VRLA or lead-acid. The multiple stage chargers will come in a variety of sizes and it will be important to get the right sized charger for the specific battery that you have.
Those who have more than one of these batteries installed in the power supply will need to get what is called a multiple bank charger which is the only thing that will work in this situation. People in certain countries will need to consider the input voltage of the charger versus the voltage of your service. Anyone who is on a tight budget will want to know that there is basic cheap deep cycle chargers available at many auto parts stores off-the-shelf for convenience. The basic battery charges will be manually operated and will not have as many special features as you might expect from a more sophisticated and expensive charger.
Maintaining a deep cycle battery of high quality requires what is referred to as a “smart charger”, which is one that is controlled by a computer and takes accurate reading right from the battery, sending the appropriate amount of voltage and currents to fill it all the way to capacity until it is done. Although the smart charges on the market are priced higher than the more basic models, they work faster and are much more effective than the standard chargers that can be purchased off-the-shelf. The fact that most smart charges have an equalizing charge that is already built-in only adds to their effectiveness. Those who need a deep cycle battery charger will want to consider their options carefully before making a final decision on one.
