Works Well

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.

Hallett 210 starting battery for mercury 502

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.

Great batteries

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.

HOLDS A CHARGE AND GREAT FOR FARM USE

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!

Great battery - still going after 4 years

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.

Excellent Battery

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.

Disappointment!

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.

One dead at 25 months

I purchased two in Jan 2020 to replace flooded wet cell batteries that were 3 years old. I was hoping the AGM would have longer life. WRONG! The 'house' battery is dead at 25 months. The alarm on the chart plotter is set at 12.3V, roughly a 50% charge. Draw on the battery while fishing is the livewell, stereo and marine radio. Last 2 times out fishing the alarm goes off only 30 minutes after shutting the motor off. Going back to flooded wet cell; cheaper and lasts longer.

AGM not worth the hype

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....

This Battery is bad, bad, bad

I bought two of these in March 2020 for my boat. I installed them in April and they worked very well for a while. The first one went bad just before the 18 warranty expired. The Sam's Club battery tester kept saying that the battery was fine, but it was not. I spent about three hours arguing with them and making them retest the battery. Finally they replaced the battery, just to get rid of me. The second battery went bad a month after the warranty expired, so I'm out of luck. I've never seen batteries that will not even last two years. I will not buy them again.
