    I have an inexpensive drill set that the charger keeps dying. Replacement chargers are very expensive. I was able to rig this charger to work on my batteries.

    This was the only 18v charger I could find for lead acid batteries. Pros: – easy to use – not expensive – charges in few hrs for 7Ah lead acid battery I was using for power wheels upgrade Cons: – first one was defective but thankfully seller sent a new one that worked when I told them of issue – clip on connectors are convenient however hard to keep them from touching now and then and unsure if this has short circuit protection.

    Bought this for my son’s upgraded 18v ride on toy. Couldn’t be happier.

    Not bad for charging batteries for my modified PowerWheels. Wish the cables were a bit thicker because I feel like i have to be delicate with these. The Status Indicator light is nice to have too.

    Upgraded sons power wheel to 18v. Spliced this charger into the power wheels harness. Charges like a charm. Particularly like the status light indicating red/green or charging/charged. Recommend!

    It works as designed. Shipped very fast. I’m using it to charge 3 6V batteries connected in series.Would buy again.

    This was purchased for a power wheels type ride on battery powered truck that I upgraded to 18v. It is an excellent smart charger for this application. And it was half the price of the same thing elsewhere.

Mighty Max Battery
Based on 3474 reviews
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
