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.

Works Well

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.

Hallett 210 starting battery for mercury 502

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.

Great batteries

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!

HOLDS A CHARGE AND GREAT FOR FARM USE

I bought one of these batteries 10 years ago and use it in my boat that runs some electronics and also serves as the starting battery. It's maintenance free and takes vibration in the boat well. AGM batteries charge faster and last longer than most others and do not discharge if left unused as lead acid batteries do. I have an onboard battery charger on my boat that gets plugged in to recharge two trolling motor batteries and this one, all are AGM. It only takes a few hours. The alternator on my outboard really is enough to keep this one charged as I run charters in my boat. I'm replacing this one with a new one just for preventive maintenance. The only other battery I would consider is a lithium battery, but the expense of them is quite high, but if a light battery is one you want, that would be it, otherwise this Duracel AGM battery is an excellent choice.

A bargain on a quality 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.

Well worth it.

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.

Disappointment!

Always trickle charged when not in active use. Worked great for two seasons and then suddenly died without warning - read 6v and wouldn't take a charge from two different chargers. Likely an internal plate short circuit.

Failed at 22 months, outside of the 18 month warranty (non pro-rated warranty). The Sam's technician insisted on testing it and attempted to argue "it needs to be properly charged". Very frustrating experience and I expect better knowledge from Sam's technicians.

Only lasted two boating seasons

battery only used in summer time for two seasons (purchased 20 month ago ).  May have used the battery a total of 20 times to power a 36lb thrust trolling motor.  Never really lasted more than an hour or so with on and off usage before it lost most of the power.   I assumed that is all the life one would get on a single charge....  Always kept the battery charged as recommended.  Less then 2 years later it wont hold more than 5 min charge.  Since warranty was for only 18 month replacement and no prorated extension, we are now looking for a new one.  So much for trying to get a better grade battery with longer life as advertised.  Would not recommend this battery as we have now learned the one we purchased has poor performance....

AGM not worth the hype

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.
