Cranking Battery vs. Deep-Cycle Marine Battery

If you’re an avid boater, you know the importance of having the correct battery for the job. Starting your motor and moving on the water requires different amounts of amperage, making it essential to use a cell designed to handle the load.

When looking at a cranking battery vs. deep-cycle marine battery, you should clearly understand the difference between the two.

Review Power Output

One of the most significant differences between cranking and deep-cycle batteries is how much power they can put out. Cranking batteries have to put out a large amount of energy in shorter bursts to ensure they don’t lose their charge.

Cranking batteries are built to give boat owners a reliable power supply for starting their motor. This discrepancy means they need to have a higher amperage than deep-cycle batteries. On the other hand, deep-cycle batteries are intended to operate for extended periods, so they use less amperage overall.

Consider Charging Capacity

Deep-cycle batteries are designed to handle a higher load capacity than cranking batteries. Since they’re constructed with larger plates, they can be discharged and recharged more without causing the cell to break down. Cranking batteries, on the other hand, aren’t meant to be fully discharged.

Charging your battery correctly is essential if you want it to be reliable while on the water. Purchasing a marine lithium battery charger will ensure your batteries stay at maximum capacity without causing unnecessary wear and tear.

Discharge Cycles

Another big difference between deep-cycle and starter marine batteries is the number of cycles they’re designed for. While deep-cycle batteries can be charged and discharged thousands of times, you’ll only get a few dozen cycles out of a starter battery.

A marine battery can last up to six years if cared for properly. However, knowing how to maintain your cells to maximize their lifespan is essential. Store them in a dry, cool space out of the way. Don’t leave them on the charger. Otherwise, you could damage them prematurely.

Use the Right Battery for Your Boat

Marine batteries are designed to accommodate different cell types to meet your needs. Whether you want a traditional lead-acid, lithium-ion, or wet-cell battery, you must learn to take care of it so that you aren’t stranded on the water.

When comparing cranking battery vs. deep-cycle marine battery, it’s evident they’re used for distinct purposes. A clear idea of what each is for will ensure you get the most out of your investment.
