What to think about before purchasing a deep-cycle battery charger
Have you got the right battery?
First things first, if you’re looking for a charger to protect your battery, is your battery worth protecting? Does your battery have enough Ampere-hour rating, marine cranking amps or reserve capacity for your needs? If the answer is yes, then look below for how to best maintain your battery. If no, think about investing in one of the top deep-cycle batteries on the market that we have reviewed here.
How do I best look after my deep-cycle battery?
The purpose of deep-cycle batteries mean that by nature, they are constructed so that they can provide a gradual amount of power over a long period of time (so that you can use them when you are away from a power source). This makes them ideal for use within recreational vehicles (RVs) as deep-cycle batteries can withstand being deeply discharged.
However, in order to keep your deep-cycle batteries in the best possible condition, it is recommended that you do keep your batteries charged when this power source is available as storing your battery with no charge may cause sulfation and may reduce the battery’s life.
Your deep-cycle battery needs to be treated with care when it comes to recharging and maintaining it, and you need to make sure that the charger you purchase considers the temperature-dependent and battery chemistry-dependent schedule that is essential for charging a deep-cycle battery.
This can get very tricky and technical if you attempt to meet your deep-cycle battery’s needs manually and you might damage your battery if you make a mistake during the charging process. The best option is to let a smart charger manage the unique charging schedule of your deep-cycle battery, so you don’t have to.
What is a ‘smart’ deep-cycle battery charger?
A smart charger will have a microprocessor that is designed to deliver the correct charging schedule for the deep-cycle battery. This means that it will first charge the battery, making sure it is at the optimal charging rate, and then cease charging when the battery has reached capacity, it should then go into ‘float mode’ where the voltage is reduced but is sufficient to maintain the battery. A smart charger will also make sure that your deep-cycle battery is never overcharged.
It does all this safely by checking your batteries voltage in order to discern the type of battery it is charging and how much charge is required.
It is wise to choose a smart charger that also comes with reverse pulse technology, this means that it will maintain the battery at the correct temperature when it is charging. This is important as it means that the battery will be charged at the correct voltage level which is an essential balance required in preventing battery failure when charging deep-cycle batteries.
How many Amps do I need?
Deep-cycle battery chargers come with different amp ratings. You will need to check the NUMBER of amp hours that your deep-cycle battery is able to store so that you can work out the type of charger you are going to need. The number of amps will also determine the speed AT which the battery will charge.
You can work out how long a particular amp charger will take to charge your deep-cycle battery by dividing the amp hour rating by the number of amps the charger has. For example, a deep-cycle battery that holds 100 amp hours would take about 10 hours to charge with a 10 amp charger if the battery was close to flat and you needed it at 100%. If you wanted a quicker charge you would need a battery charger with a higher amp rating.
As will all battery chargers the greater the number of amps, the faster your battery will charge.
What about storing my deep-cycle battery when I’m not using it?
Although it is tempting to forget about your deep-cycle battery after a long day out on your boat or other recreational vehicle it is important to carefully consider the charge levels of your battery before you put it away for storage.
Leaving a deep-cycle battery at a low charge level can damage the battery due to the potential for sulphuric acid to react with the battery plates which are made of lead. So, even if you won’t be using the battery for a while make sure that you charge it fully before storing. A top tip for extending the life of your deep-cycle battery and keeping it at optimum performance.
Deep-cycle batteries are sensitive devices and therefore need to be treated with care. When storing these batteries you need to make sure they are charged so that they don’t get damaged.
Trying to charge deep-cycle batteries manually can be tricky, and requires much time and effort in order to get the most out of the battery and ensure it lives a long life. If done incorrectly, this method may lead to damaging your battery and potentially reducing its lifespan. If this option is beyond your time constraints and capabilities the best choice is to opt for a smart deep-cycle battery charger.
Smart chargers come with in-built microprocessors which are able to charge your deep-cycle battery in the optimum environment, meaning it won’t overcharge. Using these chargers also means that your battery will work to its maximum productivity and they will also maintain your battery so that it keeps it’s charge when not in use – a technique that will extend its lifespan.
The smart deep-cycle battery chargers discussed in this article are a worthwhile investment for making sure you get the most out of your battery.
