Choosing a Lithium Battery for Your Mercury Outboard

Mercury Marine® Lithium Starting Battery.


If you’re looking for a battery to start your Mercury Marine® outboard engine, 12V Abyss Lithium Marine Batteries are the best choice. Abyss batteries meet all of Mercury Marine’s specifications for cranking battery power and accept a charge from the alternator on the engine. That means you can rely on them to start your engine quickly, every time.

But that’s not all. 12V Abyss Lithium Marine Batteries also offer a number of other advantages over lead-acid batteries, including: 


• Much lighter weight – up to 80% lighter than lead-acid batteries, making them easier to carry and install

• Higher cranking power – delivering up to 1500 Cold Cranking Amps (CCA), compared to lead-acid batteries which typically deliver only around 800 CCA

• Faster charging – able to accept a charge up to 5 times faster than lead-acid batteries

• Longer life span – with up to 10 times the life of a lead-acid battery, you’ll save money in the long run

• Maintenance-free – no need to add water or other fluids, meaning less hassle for you

So if you’re looking for a battery that will start your Mercury Marine outboard engine quickly and efficiently, choose a 12V Abyss Lithium Marine Battery. You won’t be disappointed.


In addition to being an excellent choice for starting your Mercury Marine outboard engine, 12V Abyss Lithium Marine Batteries can also be used as a dual-purpose battery for powering other onboard electronics.

Lithium batteries have a higher power density than lead-acid batteries, meaning they can deliver more power for a given size and weight. That makes them ideal for powering electronic devices that require a lot of power, such as fish finders, GPS units, and radios.

12V Abyss Lithium Marine Batteries can also be used as a “house” battery on larger boats that have multiple batteries. In this case, the Abyss battery can be used to power onboard lights, pumps, and other appliances when the engine is not running.


When you buy a 12V Abyss Lithium Marine Battery from abyssbatteries.com, you’re getting a high-quality product at a competitive price. We only sell batteries that we would use ourselves, so you can be sure you’re getting a reliable product.

We have a team of experts available to answer any questions you may have about our products. So if you’re looking for a top-quality lithium marine battery at a great price, look no further than abyssbatteries.com.

    I need to replace my group 31 AGM Start battery for my 350hp Mercury Verado.
    I have an additional Ionic 125ah lithium battery for accessories. I’m using a Yandina 100 Combiner for charging. I’m not sure if that is still needed with your charger.
    I would need a charger for these 2-batteries.
    Just worried about Mercury’s AGM requirement.

    Thanks Mike
