What to look for when choosing a boat battery jump starter?

As you understand, not all battery jump starters for boats are the same. It’s essential to consider the following factors when shopping around to make sure that a particular model will meet all your needs:

Type of boat jump starter

The two most popular types of boat jump starters depend on their chemistry: lead-acid and lithium-ion models.
Although lead-acid battery boosters are more affordable, lithium-ion ones offer far more advantages. They are multi-functional, lightweight, and portable. In addition, lithium jump starters for boats recharge within minutes, without overcharging. And last but not least, they are more eco-friendly – they don’t contain any heavy metals or toxic chemicals, which can damage a marine environment if leaked.

Considering all these benefits and positive feedback from users, I’ve picked only lithium-ion jump starters for this review.

Power of jump starters for boat

The jump starter’s power is shown in either CCA (cold cranking amps) or PA (peak amps). CCA indicates how the battery will operate when it’s cold. You measure this by setting a new, completely charged power source into a cold environment (0 degrees F) and then measuring how many amps it loses in 30 seconds. The higher the number, the more powerful the battery booster.

However, you should also consider the size of the engine, e.g., full-size motors need not less than 450 CCA. The boat age also matters – the older your boat, the more amps are required to jump-start it.

USB ports and charging outlets

It’s extremely convenient when a jump starter has USB ports and charging outlets – they are handy in case of emergencies.

USB ports are usually used to charge your gadgets’ batteries while charging outlets are suitable for powering up any devices that need a regular power source.

Some top-rated lithium-ion boosters have special ports like 19V for laptops or 12V for accessories like torches, fans, or heated blankets.

Having extra ports and outlets in your battery booster will make your life easier and give you more freedom to use electronics on board. Just make sure to read product reviews and customers’ feedback to understand how well these features work.

Safety features

Batteries, as well as jump starters, contain electricity, hence, they can be dangerous if not handled correctly. The risk of fire, trauma, and damage to the electronics is always present. So, make sure your jump starter has the following safety features:

  • Reverse polarity protection
  • Protection against short circuits
  • Overcurrent protection
  • Protection against overloads
  • Protection against overvoltage
  • Protection against overcharging.

Most marine battery jump starters include the listed above safety features. However, do check them before making a purchase!

Durability and waterproof

Durability and water resistance are the following important features to consider when choosing a boat jump starter.
Overall build quality, wide-opening and robust clamps, easy-to-handle cables are all crucial features that will significantly prolong the battery booster’s life.

Unfortunately, a boat jump starter can’t be fully waterproof; however, its cable connection port must be covered. For maximum protection, look for covers that tightly seal all ports. Plus, check to see whether the boat jump starter has an IP54 protection rating against water damage.


Can you recharge a boat battery with a jump starter?

A boat battery cannot be charged using a jump starter. The purpose of the battery booster is to provide an immediate powerful current flow enough to start the battery, following which the vehicle’s alternator will charge the battery.

Can a boat battery be too dead to jump-start?

A battery that is too drained to be jump-started is practically impossible to find.

It contains specific chemical elements, so it can’t just stop working without warning. There are no chemical reactions that could be stopped immediately. On the other hand, consistent battery failure is a sign of a greater problem. So, if you need to use a boat battery jump starter every time you start up your vessel, seek professional assistance.
