All About a Marine Battery Charger
All About a Marine Battery Charger
Accuracy and efficiency are two things to look for when purchasing a marine battery charger. It is
important to remember certain factors that will affect what charger you should choose. When you
charge your battery, it could be under a number of different weather conditions. Charging is done
under electrical conditions with a less than perfect sine wave and there is always the risk of
overcharging or undercharging your battery if you choose the incorrect marine battery charger.
In order to select the proper charger, find out the specifications of the battery you will be charging.
What is the input voltage (typically 120 or 230 VAC)? What battery type do you have (gel, flooded or
AGM)? What is your battery capacity (listed on the battery as Ah)?
If you want to maintain the life of your marine battery charger, it is best to choose a charger that will
not overcharge or undercharge. Overcharging can seriously damage your battery. You run the risk of
overheating it and causing excessive water loss. In order to charge the battery properly, you will need
to determine the battery’s capacity that you will get from the Ah rating that will be listed on the battery.
A safe charging rate is about 20 percent of the Ah capacity of your battery. For example, a 100 Ah
battery would be charged at a 20 Adc rate. So in this case, with this capacity, it should take
approximately three hours to charge your battery.
An undercharged battery can clog the plates with sulphite, completely ruining the battery and forcing
you to purchase a new battery. This would have been unnecessary, and you would have been able to
avoid this problem, with the use of the right marine battery charger.
Some of the top brands of marine battery chargers include Minn Kota, XPS on-board chargers, dual
pro battery chargers, Charles chargers and pro sport on-board battery chargers. You will have peace
of mind when you purchase a top quality charger, as you will be assured that your battery will last
longer and that you will get more use out of it. It is very convenient to have an on-board battery
charger.
It is also very important that the marine battery charger you choose has the ability to maintain power
during storage, especially if you live in a cold climate where your boat or other marine equipment will
be sitting all winter.
It is extremely important to read all pertinent information provided by the manufacturer of the battery
charger to ensure that you are purchasing one that will be compatible with the battery (or batteries)
that you wish to charge.
You should also consider the number of engines on your boat. If it is a one-engine boat, you will only
need a marine battery charger with a single cranking battery output. However, twin engines will need
a charger with dual cranking battery outputs.
If you own a smaller boat, a portable charger may be your best choice, and this is also true if you
need to charge batteries on several boats.
Regardless of the type of marine battery charger that you choose, once it is installed, the charger is
ready to be plugged in and do its job. Then it is time for you to enjoy your hours on the water having
fun, knowing that your battery is charged and ready to keep you going
