When you are considering the purchase of a marine battery charger, careful thought should go in to your decision, and this decision is even more critical when the charger is for a boat. Prior to purchase, what type of battery it is, it’s capacity, and the input voltage are all elements that you must find out about, and when it comes to using the charger, other essential items will come into play. In order to ensure that you get the most life from a battery, the primary ingredient is choosing the proper type of charger.

The fact that a marine battery charger will generally be utilized in different conditions than the other various kinds of chargers are used, is a critical factor when choosing the correct charger. You should realize that there will likely be circumstances that require that your battery be charged while you are out on the water, as boats and other marine equipment will be utilized mainly on the water. When deciding on a charger, you need to look for one that can be securely stored and transported on your boat.

It is also important that you find the right charger so you won’t accidentally under or overcharge your marine battery. Believe it or not, overcharging a battery is the #1 cause of killing a battery and the #2 cause is undercharging.

What you really want to look for is a charger that has an output of 20% of the total Ah capacity of your battery. If the charger is less than 20%, you will undercharge the battery; if the charger is more than 20% you will most likely overcharge it. To break this down let’s use an example – if you have a 100 Ah marine battery, you need to buy a 20 ADC marine battery charger.

If you’re unable to find a battery that will provide the 20 percent of total Ah capacity, then you’ll to need to look at how long it will to recharge your battery with the chargers that are available. Consider the 10 ADC charger, which will require just over six hours to recharge a 100 Ah battery. Along the same lines, a 20 ADC charger will require almost as much time to recharge a 200 Ah batter. Compare this to a 40 ADC battery charger, which will fully recharge a 200 Ah battery in three and half hours at most. You can extend this formula to any marine battery, though the time to recharge will depend on the battery size.

By ensuring the appropriate combination of battery and charger, you will get the most life from your battery. A marine battery is a substantial investment, therefore, you want to choose the proper charger to extend your battery’s life as much as possible.

If you don’t want to have any regrets about the charger you’ve invested in, then make sure you know the size and rate of your battery. Do the research on the available models before you decide which one you’re going to buy, because there are many “standard” sizes and charge rates for just about every type of battery.

Charging your trolling motor batteries is simple when done with the right equipment. Just like with an electric fence you need a wire electric fence to ensure proper care.
