    This battery is a little heavier than expected but my Mariner 4 had no problems with the battery installed. I think I’ll get an Optima Blue Top Deep Cycle Marine Battery as my main battery and use this one as a backup.

    I’ll start by putting my usage of this battery into context: I was looking for a battery to power a trolling motor as the sole propulsion source on a 12’ aluminum boat for use on two small lakes. I’ve had no less than three batteries in the past spanning from an inexpensive car battery to a higher-priced marine battery and the problem with all three was exactly the same: After about two trolling passes around the 46 acre lake, the motor would start showing obvious signs of slowing down due to battery depletion. That being stated, I was fairly dubious when I bought this battery two years ago, but it has proven me 100% wrong. I have yet to see any measurable power depletion and I’ve used it for hours on end. This battery has been worth every penny and I even bought one for my son this Christmas. The only knock I can give this battery are the flimsy handles it has. They will break, however I bought a case for it and have no issues.

    It’s a heavy battery, and holds a very long charge. After 4 hours of using it on a trolling motor, it still had 80% charge

    Fantastic batt, only reason 4 stars is weight and slow recharge rate. Knowing it’s a lead battery it ain’t a problem really. Definitely one of the best out there.

    For a 100 Ah battery, I was surprised that it didn’t run my snook light for 48 hours.

    All I know is that I took it out for many hours, like 6 hours, and ran the trolling motor at full speed most of the time. At the end of the day it was still fully charged. It’s nice to know I have a super powerful and dependable battery. Especially when you are way out on a lake. Spend a little more for safety and security. Totally worth it.

Battery arrived in a good shape package strait to my door steps
Arrived just in time to power my generator here in the cold Maine winters. Excellent service!
Arrived quickly from WALMART.COM. Perfect size and proper placement in my generator. Installation was easy. Generator fired right up. Battery came fully charged.
New battery. Ready for cold weather!
So far these Might Max batteries are good but it’s only the first day and they were on charge for 12 hrs. I’ll have to come back and do an update at some point in time. Ordered them on Amazon and got them the next day. I was encouraged by Mighty Max to make this google review and post pictures to extend my warranty for 3 months but there is no way to post pictures 🤣🤣🤣 It’s been a few months and I was able to go back and edit, so here is a video I made, the rest of the photos I have deleted. Batteries are still going strong. Update 12-11-2025
They arrived within 2 days of ordering them packaging was really good I haven't put them in my MX350 yet I hit them with my multi meter fresh out of the box and got 12.4v on both batteries so that is good
Fonctionne bien et s’est bien adaptée pour le remplacement de l’ancienne.
Battery arrived in perfect condition and 100% charge.
Strong battery! It spins my 24 hp Kohler engine super fast!
Arrived fully charged..great price
