The Very Best Interstate Marine Cranking Battery

When you need the right battery for the job at the high seas or the deep rivers, you will want to depend on Interstate. But which Interstate marine cranking battery starts up the best and deliver high performance for the investment—find you the model to look out for, just right down below.

Right Off The Bat (Or Boat)—What Is “The Best” Marine Starting Battery At Interstate?

If you need to run it down to absolute basics, it is hard to ignore the 31-T of Interstate.

Yes, there is more to a battery that just the “hardcore” basics, but in the operation process of boats and the marine life, you cannot just brush that as an aside.

Taking a look over at the 31-T, you get these features and benefits:

A large group size battery (31 after all)
Over the typical year-long range of battery (18-months vs. 12-months)
CCA or amperage for ‘cold cranking’ that borders on 1000(s) and to an average cranking rate of 1250
25-amperage distribution over 195 minutes of reservation capacity
Minimal gas outbreaks through channeling gas regulation system
Durable and Full Seal to minimize (much) electrolyte monitoring and maintenance service hours.
Relatively lightweight in opposition to other brand weights for a high-performance battery
Easy to handle and move around with a single-handle design

What Type Of Battery is a Marine “Cranking” Battery, Anyway—Does The 31-T Fit The Bill?

Okay, so the issue of a “marine” battery will always go back to the source of operation—the life at sea or fishing by a river (or something).

In a boat, as in a car, you will want to possess a battery that can:


Start up the motor of a vessel (the engine) and get things into power for later use when in the presence of propelling motion (on the water).


Start up the motor of a boat (the engine) and get things into power when the battery undergoes a temperature change due to cold weather (a great enemy of many an array).

The process of “cranking” is even more so the problem with lots of marine batteries because they cannot rely on an alternator, the same way that a car does—the lesser and faster the starting of your motor, the better.

An “ideal” marine battery possesses both abilities and—if possible—does the performance in a short amount of time, with the least amount of maintenance on your part.

Safe to say, the T-31 model from Interstate accomplishes that—and then some.

Does The Interstate T-31 Make The AGM Battery Grade?

Though the T-31 model battery of Interstate does not fully express the structure and design of a traditional AGM (advanced glass mat) battery material, you can rest in the assurance that it is full in the seal.

The importance of sealing and durability when it comes to a cranking or deep-cycle battery is equivalent to producing a more extended living cell (in the long-run).

The T-31 Interstate marine cranking battery does not only make seal design of the cell a priority, but it also does this well enough so that you will not encounter much spillage or leakage—detrimental to batteries in the long run and even the short term.
