    I just installed the battery on my alarm system and thought it might be defective. It wasn?t as my system needed a few hours to recognize it was a new fully charged battery. Very happy w battery!

    After 10 years our alarm system battery died. We researched the Mighty Max Battery and decided to pick it…buying thru saved us some $$$$ and my husband was able to install it very quickly.

Mighty Max Battery
Based on 3470 reviews
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
