AGM and lead acid batteries
Interstate Batteries Marine and RV Group 31 AGM, 12V 100Ah: published specifications
Quick answer
The Interstate Batteries Marine and RV Group 31 AGM, 12V 100Ah publishes 5 specifications and currently lists at $284.95. system voltage 12 V, capacity 100 Ah, battery group size 31. Every figure below is the manufacturer own, and nothing on this page is estimated.
A brand with a nationwide warranty counter, which is worth real money on a part that fails away from home.
This sheet exists because comparing two pieces of marine equipment usually means opening two listings in two tabs and reading past the marketing. Everything Interstate Batteries publishes for this unit is in one table below, followed by the same figures for the nearest alternatives in its category.

| Manufacturer claim |
|---|
| EXTREME DEEP-CYCLE POWER: This 2-in-1 pure lead AGM battery delivers high-cranking, extreme deep cycle power. It's designed to provide reliable force over an extended period to power your boat's motor & all of its accessories (appliances, trolling motor, audio systems, depth finders, fish locators, windlass). Not all marine batteries are the same - but this one exceeds the rest. Built with thick plates to allow the battery to continuously discharge power so you can recharge it many times over without decreasing its lifespan |
| 2X-3X MORE BATTERY LIFE: Interstate's deep-cycle marine AGM batteries pack more power into each battery. The expected service life is 3x longer than conventional flooded batteries & 2x longer than an alloyed lead AGM battery. High-quality & unparalleled service make Interstate the preferred brand of marine dual-purpose batteries |
| INTERSTATE TOUGH MARINE: Not all marine batteries are the same - but this one exceeds the rest. Built with thick plates to allow the battery to continuously discharge power so you can recharge it many times over, without decreasing its lifespan. This battery is not to replace batteries for automotive or mobility devices |
| MOST TRUSTWORTHY POWER SOURCE: For 70 years, Interstate Batteries purpose has been to deliver the most Outrageously Dependable source of power to the world. Our customers come first, so we strive to create a positive experience for all. We recycle more batteries than we sell; please return to an Interstate All Battery Center near you so we can continue recycling |

Every figure above is the manufacturer own published specification. Where a maker does not publish a figure the cell reads "not published" rather than carrying an estimate, because on ratings and currents an estimate that reads as a specification is a safety problem rather than a gap.
What is not on this page
Anything Interstate Batteries does not publish. We do not estimate a missing figure, interpolate one from a neighbouring model, or repeat a number from a forum. In this category the specifications are ratings and currents, and a reader comparing two products on a grid cannot tell a published rating from an estimate, so an estimate that reads as a specification is a safety problem rather than a gap.
If a figure you need is missing here, it is missing from the manufacturer own listing, and the place to find it is the product manual or the maker technical support rather than any third party table.
Frequently asked questions
What are the Interstate Batteries Marine and RV Group 31 AGM, 12V 100Ah specifications?
Interstate Batteries publishes 5 figures for this unit: system voltage 12 V, capacity 100 Ah, battery group size 31, chemistry AGM, cold cranking amps 925 A. Everything in the table above comes from the manufacturer own listing rather than from measurement or estimation, and anything the maker does not publish is left out rather than guessed at.
How much does the Interstate Batteries Marine and RV Group 31 AGM, 12V 100Ah cost?
It currently lists at $284.95, though prices in this category move constantly and the figure on the product page is the one that governs. Where two products are close on price, the specification table above is usually a better guide to which is right for your boat than the difference between them.
Are these figures measured or published?
Published. Every number on this page comes from the Interstate Batteries listing for this exact unit. We do not test equipment in person and we never claim to, and nothing here has been derived, interpolated or rounded from another model. That is also why some rows in the comparison table read "not published" rather than carrying a number.
Why do some comparison cells say not published?
Because that manufacturer does not state that figure for that product. Makers publish different subsets of specifications, and rather than fill the gap with an estimate we leave it visible. On ratings, currents and capacities an estimate that reads as a specification is how somebody ends up with equipment that does not do what they believed it would.
Is this the current model?
It is the unit at this listing, which is the most reliable way to identify a specific product in a category where model names get reused across generations. Manufacturers frequently sell several generations alongside each other, so check the model number in the title against the one you are comparing rather than relying on the family name.

Researched, not professional advice. This page is compiled from published engineering and regulatory figures, manufacturer specifications and owner-review consensus, not hands-on testing. Figures described as a rule of thumb are boating convention rather than published standards, and they are labelled that way wherever they appear. Marine electrical work is not house wiring. Use tinned, finely stranded marine cable, size it for voltage drop and for the ABYC E-11 ampacity table rather than one or the other, and put overcurrent protection within seven inches of the battery positive terminal, because everything between the post and the fuse is unprotected. A lithium battery needs a charger with a lithium profile. Never load a boat past its capacity plate, and remember that canoes and kayaks carry no federal capacity plate at all, so their stated capacity is the manufacturer own figure. Wear the life jacket, and treat early season water as the hazard it is: cold water immersion takes your breath and then your hands long before it takes your core.
