We just bought two more for our trolling motor. We previously bought the same battery for our 140 Suzuki outboard and it has held up great for the past year. We haven't had a chance to run the boat much this year but if we have any problems I will come back and update.

Boat meets the CCA for my starting battery on my mercury 502 big block, just installed beginning of 2020 season but I have been able to let it sit for 2 or 3 weeks and it starts right up every time.

I have had two of these batteries since 2017, connected to a small solar system. They have performed well in that time. They do like to be charged daily.

Chose the AGM model based on feedback from techs because of the 100% maintenance free feature of an AGM sealed battery. I have used it for and 8' boat with a 13lb motor, and a 14' canoe with a 30lb motor and it has provided all day fishing trips for both using the trolling motors for primary propulsion. It is heavy, but maintenance free and slow battery charge drainage are great! Excellent little battery.

I bought this battery in the beginning of the 2014 season. I did my due diligence of research. This is an East Penn battery. Like anything else, with proper maintenance it will last. 15 foot BlueFin 30hp Johnson. I troll with a 45lb Minn Kota for a few hours a day with 2 people on board with a full cooler and gear. I set my fishfinder alarm for 9 volts and IF the alarm sounds it still spins the starter off like new. One day trolling hard for 3 hours my buddy asked how long the battery lasts, told him I don't know, but I can start the engine if you want. Back to maintenance... the 4 amp charger on my 30HP Johnson wont bring it all they way up on a 4 mile return to the dock. Put the Schumacher charger on it at home and do it again tomorrow. Looking forward to the 7th season.

I use this to power an electric fence for goats - solar charged, the set up has some shade in the wintertime, and this battery will draw down until the charger shuts it off, about 11.5 volts. Been doing this with two of these batteries, purchased at the same time (I change one for the other when they finally can't be kept up by the solar) for over 6 years, and they are just now getting to the point they won't hold a charge. Good battery for the price, and AGM / maintenance free can't be beat!

I purchased two of these and four AFG Golf batteries. The 34M that was used as a starting battery for a 27hp diesel engine..just started to lose cranking amps. The battery held up for four years and operated in a hot engine room. I will purchase another.

A great deal on quality AGM Marine batteries. The negative reviews are most likely due to using an incorrect battery charger. AGM batteries have a much lower internal resistance compared to sealed lead-acid. Typical chargers run as much current as the battery will accept since the high internal resistance moderates the amount of current. If AGM is charged with a regular charger (no AGM setting) the charger will use too much current when charging and damage the battery with each charge cycle.

Purchased the battery on August 2025 and completely dead on February of 2026. Battery will not take a charge. It shows 12.45 volts after charging for 24 hours with a NOCO 10-amp charger and had only 8.5% of the required amps. Battery was also connected to a trickle charger since new. Very disappointed with this battery. I have other brands deep cycle batteries on my two RV's and my other boat going to 5 years with no issues. I do not recommend these batteries.

I bought two and they lasted just out of the warranty period and completely died. I went back to flooded cell Interstates, as I got over 6 years out of the last ones and they were still going strong. Interstate also has a better warranty and stands behind their product. I would NOT buy this product again.
