Interstate BatteriesMarine/RV Battery 12V 100Ah 925CCA (31M-AGM) Dual Purpose Power Pure Lead AGM RV & Marine Starting Replacement Battery (Group Size 31M) Boats, RV's

This is a large battery, bigger than I expected. But it sure packs a punch. It fit well in my Ski Centurion even though it was so big.

Good quality for what I needed it for

Put one of these in my Tractor, excellent battery -- wish I would have put two in my Truck.

Like another purchaser I got 2 bad batteries! What a hassle! Now I have to figure out how to get them replaced and back to the boat ...

I have a 28 foot boat and a 36 foot diesel pusher motor home that just happen to need new start batteries at the same time. I have used Interstate batteries in the past and have been extremely happy with their performance so I jumped at the chance to try this one. The battery is an exact fit for the OEM size and requirements for my boat. The battery was shipped in a much larger box and cocooned in a thick heavy duty padding. It is heavy and I'm sure the delivery driver was thrilled with the weight. The battery arrived fully charged and ready to install. I initially installed it in my boat for use in prepping the boat for winter storage and then installed it into my motor home for use until next spring. I have used it for approximately six week under heavy load conditions and have monitored the charge / discharge / charge and it has performed perfectly as designed. The battery is powerful enough to start the large V8 engine in the boat as well as the Cummins diesel engine in the motor home on cold days. I checked the price at various suppliers and could not find a lower price.I have an Interstate battery in a Mazda RX7 convertible that is now 10 1/2 years old and is working perfectly. The original warranty on that battery was for three years. I have always been happy with Interstate and I believe this battery will give me great performance for many years.

Great while they last, just don't expect them to last. Original purchase was in 2021, 1st warranty battery exchange in 2024 just shy of the warranty period. The replacement lasted 9 months.

This is a vine review meaning the product was provided to be reviewed.This product is a lead acid glass mat dual purpose battery that can be used for starting engines as well as deep cycle applications. The product is well packed on all sides with foam (sides and top) and Styrofoam (bottom) within a brown cardboard box.This is a 12 V high capacity battery with 1150 cranking amps and a 200 minute reserve time. It is dual purpose and is also a deep cycle battery for running accessories with 100 amp hours capacity.It is a good size battery measuring 13 x 6.8 x 9.4 inches and weighs 72 pounds. The product has slide-up carrying handles on each side. See attached photo of battery with a pop can as a size reference.The product features both post terminals and threaded terminals. Threaded terminals are more robust and reliable than post terminals. I converted my boat from post battery cables to threaded battery cables and haven’t had a starting problem since. The product includes stainless washers and nuts matching the battery’s threaded terminals, a convenient touch. See attached detail photograph of battery terminals.This product comes with a three-year warranty. See attached photograph of battery label showing warranty duration.Because this battery is also a deep cycle battery, in addition to use in my vehicle and my boat, it would also be a good battery for my 12V back up sump pump.In summary, this battery is everything I could ask in a 12 volt battery. It’s superior AGM technology, together with it’s high capacity and deep cycle ability, make it a solid choice for most applications. I am glad I ordered it.

$1,000 for 2 batteries and the damn things are dead. Test your stuff before you send out
