Can You Jumpstart A Boat Battery?
Yes, you can jumpstart a dead boat battery. In fact, you can jumpstart it with a portable jump starter, just like how you jumpstart a car battery. This is because both car and boat batteries have 12 volts, and virtually all portable jump starters can boost a 12-volt battery.
How Do You Jumpstart A Dead Boat Battery? 6 Easy Steps
To jumpstart a dead boat battery, follow the steps below.
Step 1 – Open The Battery Compartment
Go to the compartment where the battery of your boat is located. Open it and take a look at the battery terminals. Ensure they are not corroded. If you see any sign of corrosion, you need to wash it off immediately.
Step 2 – Connect The Red Clamp To The Positive Battery Terminal
Identify the positive battery terminal. It is usually labeled P or POS, or it could have a + sign. If you’re not sure, you can seek assistance. Connect the red clamp to the positive battery terminal. Make sure it is firm.
Step 3 – Connect The Black Clamp To The Negative Battery Terminal
Connect the black clamp to the negative battery terminal. Some jump starters have a blue clamp instead of black. The red one is the positive clamp, while the blue one is the negative clamp.
Step 4 – Crank The Engine
After connecting the clamps correctly, switch on the jump starter. Now, you can go and crank the engine of your boat, like you do when you want to start it normally. If it does not start at once, wait after 5 seconds. Let the jump starter rest for up to 3 minutes before you crank it again. It should start after several attempts.
Step 5 – Disconnect The Jump Starter
You can now disconnect your jump starter. Remove the black clamp first before removing the red clamp. Power off the jump starter and take it away.
Step 6 – Charge It Later
Although you can use your jump starter to jumpstart a boat or car multiple times on a single charge, it is advisable to charge the device after every jumpstarting session. So, don’t forget to charge yours immediately after the jumpstarting session or later in the day.
How Many Amps Do I Need To Jumpstart My Boat?
The required amperage depends on the size of the battery. And it also depends on the voltage of the battery. Generally, it takes between 150 amps to 1,200 amps to jumpstart boat batteries. More so, if the voltage of your boat battery is 12 volts, you need only 150 amps to jumpstart it.
You really don’t need to worry about the amperage. All you need is to pick any of the jump starters reviewed above. All of them are strong enough to jumpstart your boat battery when they are fully charged.
How Do You Jumpstart A Boat With Two Batteries?
To jumpstart a boat with two batteries, you have to connect the red clamp to the positive terminal of the first battery, and you connect the black clamp to the negative terminal of the second battery. That’s the major difference between jumpstarting a boat with a single battery and jumpstarting a boat with two batteries. Now, let’s break it down into steps.
Step 1 – Open The Battery Compartment
Go to the compartment where the battery of your boat is located. Open it and take a look at the battery terminals.
Step 2 – Connect The Red Clamp To Positive Battery Terminal
Identify the positive battery terminal. It is usually labeled P or POS, or it could have a + sign. If you’re not sure, you can seek assistance. Connect the red clamp to the positive battery terminal of one of the batteries. Remember, the two batteries are joined together.
Step 3 – Connect The Black Clamp To The Negative Battery Terminal
Connect the black clamp to negative terminal of the other battery.
Step 4 – Crank The Engine
After connecting the clamps correctly, switch on the jump starter. Now, you can go and crank the engine of your boat, like you do when you want to start it normally.
Step 5 – Disconnect The Jump Starter
You can now disconnect your jump starter. Remove the black clamp first before removing the red clamp. Power off the jump starter and take it away.
