    2nd one I have owned the first one even though they are sealed a sealed battery the top can be removed and you can use a baster syringe with distilled water to top off adding many more years. I missed doing this however this battery lasted 5+ years!!! If you examine the top of the battery you will notice a plastic cover which covers the rubber cell refill caps. remove is using a turkey flavor injector syringe carefully not to over fill each cell. For best results FIRST PLACE your battery in a empty plastic tub HOWEVER DO NOT REPLACE THE RUBBER CAPS JUST YET . next connect your battery charger and start charging. when complete wipe off any water on the top of the battery THEN reinstall the rubber caps. NEXT Using some clear silicone or any color you like reseal the plastic cover. You now have a battery which will work for a few more years. IMPORTANT NOTE. When you first remove the cover and then the rubber caps using a flashlight look into each cell to make sure they are still covered with water… if not you were too late and the plates will be ruined. Best practice is to remove the cover no later that the 3rd year. Check the water level and refill then. Set many reminders using your phone or calendar or any other reminder program you have. When that reminder goes off do not delay or put off do what I said right away and you will get many many more free years out of your lead-acid batteries. I run a 28 battery backup system and I was able using this practice to get 15 solid years from those batterys. This info is free enjoy!

Arrived quickly. Even got a sticker with it.
Solid looking battery, came well packaged. Have used their battery before for my lawnmower and now looking forward to see how it lasts in my snowmobile.
I can't believe it less than 48hrs since I ordered from Walmart and it's in the machine. What more can I say except great price.
Thanks Larry
Item as described and perfect fit and arrived on time
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
