The summer months are finally here and how to charge a boat battery on the water? Whether you’re a seasoned fisherman, or just looking for something new to try, one of the first things you’ll need is a boat battery.
But this isn’t as simple as driving down to your local hardware store and picking up an off-the-shelf model. Boat batteries come in several different shapes and sizes so it’s important to know what type of battery is best for your particular needs.
A fully charged 12v lead acid AGM deep cycle marine battery can power most fishing boats up to 18 hours before needing recharging which makes them perfect for longer day trips on the water.
Different Ways Of Charging A Boat Battery:
The most common deep cycle batteries used in fishing boats are AGM (absorbed glass mat) batteries. These have several benefits that make them a great choice for use around water. First, they’re sealed so they can’t spill or leak acid if they’re tipped over.
This prevents corrosion and other damage to the surrounding area which would normally happen with batteries that use liquid electrolytes. Another benefit is the fact that they’re manufactured with thick lead plates and strong absorbent glass mats to extend their life cycle by up to 3 times or more. This means your battery will last for several seasons instead of just one.
The downside to all this extra power, though, is it takes longer for AGM batteries to charge. If you’re out on the water and your battery runs low, you’ll need to find a way to charge it up.
Charge Your Battery With A Solar Panel:
One way to charge your battery while you’re out on the water is to use a solar panel. This can be a great option if you’re in an area with plenty of suns and don’t have access to an electrical outlet. Solar panels come in all shapes and sizes, so it’s important to choose one that’s best suited for your needs.
Charge Your Battery With A Battery Charger:
If you’re not using a solar panel, the next best option is to use a battery charger. This can be plugged into an electrical outlet onshore or even your boat’s cigarette lighter socket. When choosing a battery charger, it’s important to make sure the amperage is high enough to charge your battery in a reasonable amount of time.
This will vary depending on the size and type of battery you have so it’s important to read the specifications before buying.
Charge Your Battery With An Inverter:
Inverters are another option if you’re not using a solar panel or battery charger. Inverters can convert 12v battery power to 110v household current which can be used to run appliances or charge devices like cell phones, laptops, and tablets.
This is a great option if you’re camping or tailgating and need to keep your devices charged up.
Use A Portable Generator To Charge Your Battery:
If you’re not near an electrical outlet, the next best option is to use a portable generator. These come in a variety of sizes and can be powered by gasoline, propane, or diesel.
They’re a great option for charging your battery while you’re out on the water or even when you’re at home if the power goes out.
Connect The Boat’s Alternator To Shore Power And Turn It On:
If you have access to a standard 110v household outlet, the easiest way to charge your battery is to simply connect the boat’s alternator to shore power and turn it on.
This will provide a steady stream of power to your battery while you’re docked and will help keep it charged up for the next time you hit the water.
Use An Onboard Charger, If Available, For Charging While At Anchor Or Moored:
If you have an onboard charger available on your boat, it’s a great option for keeping your battery charged while at anchor or moored.
This will charge your battery using the boat’s alternator while you’re not using it and can help keep it topped off so you’re ready to go when you hit the water again. With a little bit of preparation, you can easily charge your boat battery while you’re out on the water.
If You Have No Other Options, Use Jumper Cables From Another Vehicle To Jump Start Your Engine And Charge The Battery That Way:
If you have no access to an electrical outlet or any other way of charging your battery while you’re on the water, it may be possible to jump-start your engine and power the boat’s house battery that way.
This will require another vehicle but if that’s not a problem, you can jump-start the boat’s engine using jumper cables from the other vehicle and continue on your way. Just be sure you know what you’re doing or else this could turn into a dangerous situation.
If All Else Fails, Call For Help:
If none of these options are available, the last resort is to simply call for help. If your boat doesn’t have any power at all, it’s going to be impossible to launch it and head back to shore. You can call a tow truck or other more heavy-duty vehicle for help, if necessary.
Whichever way you choose to charge your battery, there are a few precautions you should take. First and foremost, be sure to read the instructions for whatever charger or inverter you’re using. Many of these devices have specific instructions on how to safely connect them to your battery.
Also, be aware of the dangers of electrocution or electrical shock. This is especially true if you’re using a portable generator to charge your battery. These devices put out a lot of power so be sure to keep yourself and anyone else nearby away from water and stay dry while charging the battery.
Whatever charging method you choose, it’s important to remember to never leave your battery charging unattended. This could lead to a fire or other disaster. Always make sure you have someone around to keep an eye on things while the battery is charging.
Now that you know how to charge your boat battery, it’s time to get out on the water and start fishing.
