Battery Types

There are distinct differences tailored to varied uses regarding the battery types of the 24MS and 24DC. The 24MS is fundamentally a starting battery specifically designed to provide high cranking power to start boat engines.

On the contrary, the 24DC is a deep cycle battery, primarily engineered to provide power over an extended period of time, suitable for both marine and RV applications, proving superior cycling and recharge capabilities.

Reserve Capacity

Reserve capacity is pivotal for maintaining essential functionalities in case of alternator failure or when the main power source is unavailable. The 24MS offers a reserve capacity of 130 minutes, ensuring continued power for onboard electronics for a fair duration after the primary energy is depleted.

Meanwhile, the 24DC sports a slightly lower reserve of 120 minutes. Yet, it still provides a robust backup for sustaining crucial appliances and devices.

Cold Cranking Amperage

The cold cranking amperage (CCA) denotes a battery’s ability to start an engine in cold temperatures. With a CCA of 500, the 24MS demonstrates a solid capacity to ignite boat engines even under chilly conditions. 

The 24DC surpasses slightly with a 550 CCA, rendering it somewhat more reliable in freezing temperatures. It might be particularly advantageous for RV users in colder climates.

Marine Cranking Amperage

When discussing marine cranking amperage (MCA), the 24MS and 24DC exhibit distinct capacities. The 24MS offers a potent 625 MCA, revealing a high-performance cranking power crucial for marine applications.

Conversely, the 24DC slightly tops the cranking prowess with an MCA of 690, thereby ensuring enhanced somewhat reliability in kick-starting the engine.


The 24MS and 24DC batteries operate on a 12-volt system, catering to the standard requirements of a wide range of marine and RV applications, providing a consistent power supply to fulfill regular operational needs.

Group Size

Group size, which pertains to the physical dimensions and placement of terminals, is identical for 24MS and 24DC, being categorized under group 24, ensuring they are compatible with an assortment of boats and RV setups.


Warranty coverage is pivotal for ensuring longevity and reliability. The 24MS and 24DC come with a 1-year free replacement warranty, ensuring users have a safety net in case of unexpected issues or premature failures.

Dimensions (LxWxH)

Adhering to standard group 24 specifications, 24MS and 24DC showcase identical physical dimensions of 10.25 x 6.88 x 8.69 inches, affirming compatibility with a wide array of installations without necessitating modifications.

Terminal Location

Regarding terminal positioning, the 24MS and 24DC adhere to a consistent design. The positive terminal on the top left front and the negative terminal on the top right front facilitate standardized installation and replacement processes.


The weight can influence the ease of installation and weight distribution of the vehicle or vessel. The 24MS is slightly lighter at 39.35 lb. At the same time, the 24DC, due to its deep cycling capabilities, weighs in at a marginally heavier 45.41 lb.

Important Features

It is crucial to note both batteries bring forth important user-oriented features such as free battery testing & installation and a maintenance-free design under normal operating conditions.

Moreover, both models advocate environmental stewardship, offering free lead acid battery recycling at local Walmart locations.

Our Observation
From the details provided, EverStart offers two distinct types of lead-acid marine batteries, each with its strengths. I’m particularly impressed with the Group Size 24MS for its affordable price of $74.87 and 625 MCA, making it suitable for marine starters.

On the other hand, the 24DC, priced slightly higher at $89.74, stands out with its superior 690 MCA and a commendable 101 amp hour, ideal for deep cycling in boats or RVs. Both batteries have a year’s warranty and the convenience of free installation and testing at Walmart Auto Care Centers.

Their dimensions and terminal positions are identical, ensuring a consistent fit across models. Whether you’re sailing the seas or hitting the road, these batteries are reliable choices.
