Tips for Choosing the Right Marine Battery Charger
First of all, decide what type of battery you are going to have and note its specifications on a piece of paper when starting to shop for the best marine battery charger on the market today.
Note its input voltage, capacity of full battery power, the amps per hour. If you have this information, then shopping for a battery charger should be quick and easy.
Also, try to find a charger that will not overcharge the marine battery even if that means you would be spending a little more than you were initially planning on.
The same goes for marine battery chargers that do not undercharge as that might mean you will find yourself with an undercharged battery in an emergency.
Why Overcharging Kills Your Battery?
Overcharging the marine battery kills it over the long haul as it disrupts its contents, marine batteries are made out of lithium that lose their charge properties when constantly overcharged.
Plus, overcharging the marine battery can lead to extreme overheating that damage it completely.
This happens because when a battery is overcharged, excessive gasses are released, this leads to overheating of the electrolytes inside the battery as hydrogen and oxygen are released.
This could be fatal to the life of the marine battery as its enclosed design will cause it to burst once the gasses reach the maximum limit.
However, if you have a lithium battery then there is no reason for you to worry as lithium batteries have built-in circuits that prevent overcharging.
To avoid overcharging a standard marine battery, find out it capacity and make sure you purchase a marine battery charges to fit that capacity.
Safety and Durability of a Marine Battery
Nowadays, there are a lot of marine battery chargers that have an epoxy-filled construction and are waterproof.
This construction of the marine battery also ensures that no shocks take place and the condensation does not occur.
Plus, it also helps prevent sparks and ignition of the marine battery so make sure that you only buy ABYC safety standard compliant marine battery.
Charging Time of Marine Batteries
Always take into the consideration the time span needed to fully charge a marine battery and remember that it is always proportional to the size of the battery.
Hence, the larger the battery, the more hours it will require to fully charge. Therefore, think about how big a battery do you really need?
As mentioned above, marine batteries should always provide the right voltage-not too little not too much.
Often, marine batteries range anywhere between 6-12 Volts and if it’s a multiple battery then the connection should be parallel.
Never connect the marine batteries in a series connection as that will make charging very uneven and unbalanced thereby causing significant damage to it and cutting its battery life short.
We believe that this list should offer the guidance you were looking. The marine charges mentioned here are all manufactured by reputable companies and have a reputation for working efficiently over a long period of time.
To prolong its life, try to charge the batteries after each use and never mix old batteries with new ones.
Plus, never leave the batteries too deeply discharged, the safest level is about at 80% and remember that shallow discharges last the longest.
