What Battery Capacity And C

The battery capacity determines how much energy you have available to power electric motorboats, accessories, and other devices with only one charge. The C-rate defines how much electrical current can be provided by a battery during a period of time. Generally, C-rates are given in terms of 20 or 10 hours. The electrical current provided at those rates gives you a reference of how much electrical current a single battery can give you. The higher the current, the faster the battery will discharge.

You might want to estimate the load and time of usage required from the battery in relation to the devices installed on your boat. With this list, you can do an estimation to choose the best battery for you.

Should You Consider Marine Battery Group Size When Buying A New Battery

The marine battery group size makes it much easier for boat owners to choose their battery. In some cases, the boats already come with some predefined type of battery that can be installed, and these fall under some of the most common categories on the list.

Group 24 marine battery and group 27 marine battery options are among the most commonly picked and popular choices within the marine battery group size chart. The group 24 marine battery models tend to have a medium capacity, suitable for several marine applications with low- to mid-consumption boats. The group 27 marine battery options have a higher price but also a much higher capacity, making them excellent in powering the motor and several common devices.

Another excellent choice for marine applications is the 31M and 34M group marine batteries. These have relatively high capacities with an excellent C-rate, meaning that they can easily power medium and large boats alongside several electronic devices installed.

How Fast Can You Charge The Battery

The charging speed for your battery depends on the parameters set by the manufacturer. The best thing you can do to properly charge your battery is to get a marine battery charger that allows you to set the right charging parameters. By doing this, you will be extending the life span of your battery.

Most batteries on the list vary their charging currents from 10 amps to 30 amps. Considering an 80% DOD, this means a charging time of 480120 min for 100Ah batteries, 24080 min for 50Ah batteries, and 9030 min for the 20Ah battery.

Types Of Boat Batteries: Starting High

There are 3 types of boat battery: the starting high-rate battery , the deep-cycle battery , and the dual-purpose battery, which handles both functions. Some boats need just one kind of battery, some need both, and one cant be swapped out for the other.

The cranking battery is designed to deliver a lot of power very fast. Boat engines need that kind of quick, sharp burst of power to get the engine up and running. From there, the engines alternator takes over to keep the boat going.

Deep cycle batteries help you run boat systems like lights, stereo systems, and other functions while the boat is at rest on the water. For example, if you go fishing youre typically going to drive the boat out to a spot, turn it off, and settle in. Youll want a battery with a lot of discharge and recharge cycles to support these activities.

The dual-purpose battery works for very small boats who only have room for one kind of battery, but which make use of both battery functions. The advantage is, of course, only having to buy and worry about one kind of battery. The disadvantage is the dual-use battery will not perform either function as well as the single use batteries will, offering a weaker fast-charge than the cranking battery and fewer recharge cycles than the trolling battery.

Charging A Boats Battery

Unlike cars that are used almost daily, boats are less likely to be on the waterways every day of the year. This explains why an automobile battery tends to last longer in cars than even the best marine battery in a boat.

If you have to leave your boat in storage for a while, it is important to make sure the battery retains its charge. Trickle charging or regulated charging is recommended when the boat will be out of use for a long period.

Also, remember to properly charge the battery in a boat you just purchased, whether it is a new or used boat. The batteries that come with a new boat will typically lose most of their charge while in storage.

If youve had a battery for a while, and it suddenly goes dead when you go to start it one morning and will only come to life when you plug in the charger, you may need to start preparing to replace the battery.

Are Marine Batteries And Deep Cycle Batteries The Same

Regular marine batteries are often used as starter batteries, or cranking batteries, for starting the motor, but can sometimes be dual-purpose batteries too. Starter marine batteries are usually designed to deliver short bursts of energy, such as providing a surge of power when starting an engine.

A deep cycle boat battery is designed to provide continuous power over a period of time. A deep cycle marine battery will feature thick, solid plates that are heavier than those used in starter batteries.

Deep cycle marine batteries can also be discharged to low as 80 percent of their capacity without causing any damage. Ideally, a deep cycle boat battery is designed with an operating range around 60 percent.

Can I Just Use a Marine Battery?

It can be tempting to some people to consider using just one marine battery for both cranking and trolling. However, if a starter battery is used for trolling or any other marine application that requires continuous use, it may have a higher risk of overheating. It can also degrade the battery in a matter of weeks.

On the other hand, deep cycle marine batteries may be better suited for continuous use, such as when trolling, but may not always perform as expected when needed as a starter battery. In order to achieve the most reliable results, it’s usually advisable to consider using two batteries.

What Are Deep Cycle Marine Batteries

Deep cycle marine batteries are designed specifically for life on the water. Made using durable components, a deep cycle boat battery is built to provide reliable, continuous power in a number of marine applications.

What’s more, deep cycle marine batteries are made with a thicker plate construction compared to other types of batteries. The thicker plate means the battery is less likely to overheat and it’s designed to withstand the rigors of engine vibration, wave pounding, trailer transport and high temperatures in heavy currents or harsh weather conditions.

What To Look For When Shopping For The Best Boat Battery

The Best Rated Boat Batteries

Your application will determine if you need a starting battery, a deep-cycle battery system, or maybe you only need a single multi-purpose battery. The best boat battery for you will always depend on how youre using it. Regardless of your application, there are some things to keep in mind when looking for any marine battery.

Efficiency is critical. Efficiency in a battery means that you can discharge your battery to 80% or more of its capacity without damaging it and then recharge it quickly.

Reliability and lifespan are also essential to consider when selecting your marine battery. You dont want to be a few miles off-shore on a fishing trip and not be able to start up your motor to get home because your battery died. Likewise, imagine taking your friends out on your sailboat for a weekend and having your battery system croak on you. Thats not going to make for a fun vacation. Beyond that, batteries are expensive. Having to replace them frequently because they dont have a long lifespan or warranty will add up quickly.

And last, but certainly not least, weight. Batteries can be very heavy. This starts to become a significant consideration in live-aboard and trolling battery systems where you likely need multiple batteries to provide the capacity you need.

Ultimately, youre looking for the lightest, most efficient, and reliable battery you can afford. Lets look at some options.
