Picking the Right Deep Cycle Marine Battery Charger
Picking the right deep cycle marine battery charger is crucial to you having the tool you need to maintain the batteries you own. There are many different features on these charging systems that make them better choices according to how you will be using the device.
The majority of the newer battery chargers have increased safety features due to the latest technology and developments. You want a charging system that has the following safety features.
- Reverse polarity protection
- Over-charging protection
- Anti-spark technology
Waterproof and Dust Proof
Most marine batteries are deep cell batteries so it makes perfect sense to have a battery charger that can be exposed to high humidity, or some moisture. If you are using the charger on an item that is often exposed to dust like the dust from traveling a dirt road down to the boat launch you want to make sure that the dust is not going to stop your charging system from operating properly.
If you have multiple devices that have batteries of differing voltages then you want to choose a charger that is capable of charging multiple voltages. Many chargers can charge 6 volt or 12 volt and some chargers can even charge 6 volt, 12 volt or 24 volt batteries.
Multiple Connectors or Charging Banks
If you have several batteries that you would like to keep a maintenance charge on then you want to buy a charger that is capable of charging multiple batteries at the same time. You can buy chargers that are designed to charge three or more batteries at one time and provide all of the batteries with the optimum charges. You can use them as your car battery chargers also.
Chargers that Recondition Batteries
Many of the battery chargers are now capable of evaluating your battery for a sulfate build up on its plates and performing a reconditioning that reduces that sulfate and extends the life of your battery. Lead acid batteries are the most prone to developing sulfate build up.
Many chargers also evaluate battery health and will let you know if the battery you have connected is no longer healthy enough to receive and maintain a charge.
Ability to Charge Other Items
The majority of people have cell phones, tablets or digital cameras with them most of the time. Some chargers have USB ports that allow you to charge those electronic devices while you are away from home.
When you are selecting a battery charger you must consider what types of batteries you need to charge, and how they need to be charged.
Deep Cycle Battery Size Guide
Batteries that are meant to be used on cars, trucks, and large motors on boats, etc. are often referred to in a ‘group size’. The group size tells you which battery is the most appropriate for the location it will be in, and the physical dimensions of the battery and case.
For deep cycle batteries that are meant to be used on boats and large water craft the group size is usually a reference to the physical size of the battery. The larger the battery is then the larger the group size of the battery is. Batteries are measured by their length, their width and their height, so make certain that you know where the battery will be placed and what dimensions are available for the battery in that compartment. The dimensions of a battery are determined by measuring the battery at the widest point. Most batteries are longer and wider at the top and they gradually decrease in size down the sides and to the bottom.
If the group size of a battery has an M in the name of the group then you can be sure that the battery is designed for marine or ATV usage. Marine batteries and automotive batteries can both be deep cycle but they have different construction so they are not readily interchangeable.
Do not confuse the cold cranking amps that are displayed on a battery with the size of the battery. The cold cranking amps describes how many amps are provided for cranking your engine when you initially turn the key and does not describe the physical size of the battery.
The Battery Council International (BCI) delegates numbers and letters to batteries to indicate what group size the battery fits in according to the size of the battery, the terminal location, and the battery type. Some vehicles can accommodate a battery from more than one group size so you should always consult a buying guide before you purchase a battery that has a group size different than the one listed on the battery you are replacing.
A battery charger is a handy tool for anyone that owns a vehicle, boat or lawn equipment. Finding the best deep cycle battery charger will require you to evaluate the battery you need according to the equipment you have, and then determine how you will use the charger. There are portable chargers and there are chargers designed to maintain several batteries at one time.
Pay close attention to the features offered by the different chargers when you are making a comparison. You want a charger that will work on the type and size of batteries that you use around your home and during your recreation time.
The right charger will maintain your battery and improve the longevity of your battery as well.
