    I put these batteries in a Black and Decker 36V Lawn Mower battery I bought in 2013. All that was needed was new batteries to restore it to power that it had when new. The install was fairly easy there are youtube videos that explain it. I needed to cut out a small piece off the case to fit in one of the batteries flush. It showed how easy that is in one of the youtube videos for B&D 36V battery replace. This saved me about $400 that a new self-propelled lawnmower would have cost. If I can get 2 or 3 years more out of this mower it will be well worth it. When you install the new batteries be careful with the gray piece that connects into the gray piece on the lawnmower. There is a very small bar that secures the gray piece to the case. You want to keep all that intact. so it snaps into the mower body.

    This is my second order of three of these batteries. The last three ran for about 2 years, which is what you can expect for an electric lawn mower. Make sure you fully charge them before using them the first time, and make sure all the leads in your electrical device are clean from corrosion.

    These batteries are great for power wheels and other ride-on vehicles. I have one Mighty Max battery that’s been going strong for 3 summers now- still holds a charge as good as the new set I just bought. I tried Chrome batteries and they lasted one summer. Won’t make that mistake again.

    Put this in the 3 year olds barbie jeep, works fantastic. Wired in a 12v socket outlet on the side like a tesla plug and put the male end on a 12v battery tender for easy charging. Kid loves the extra run time and easy to plug in without worrying about polarity. She also runs a radio and Bluetooth speaker wired into the battery and it handles everything as expected.

    A great backup battery for my ham radio and other emergency equipment. Sometimes use it with a small inverter to power patio lights in the backyard. Charges USB devices, as well. My last Mighty Max battery lasted 3 years before it gave up to the Arizona summer heat in the garage. Also used a Coleman solar panel to charge it while camping or helping our local PD with traffic management.

    I chose this because it fit the same exact footprint as my original ride on toys battery. However, mine was originally 12ah and the company only offers a 10ah for $100! This was 15ah for a fraction of the cost. I was able to take the connector and handle/case off my old battery and put it on this one. Installed product is identical to original but 15ah.

    Battery is a perfect replacement for the Kidtrax police car ride on toy. Just take the plastic case of the old battery. Disconnect the wires and then install on this new battery. Batteries are the same size physically but this one holds more charge.

    Used this as replacement of my daughters Bens power wheel battery. The original battery was 12v 12ah so the 15ah gives it a little longer run life. Also its the same dimensions so the original battery casing and plugs swapped right over. You cant tell a difference. This was a true plug and play replacement.

    I used these to upgrade my kids Power Wheels Baja Extreme to a 24v so I bought two. Even using one before the upgrade, the Batteries seem to outperform the stock battery that came with it. I have purchased these in the past for Power Wheels upgrades and have always been happy with the product. The 15ah is the largest size you can buy to where the battery will still fit in the compartment. The 18ah battery is too big. Upon receiving, I was pleasantly surprised that the batteries were pretty much charged and only required a mere top off. They have been sitting now for over two months due to the winter weather and I just checked to see if they discharged any and they have not! Still fully charged.

    Added 2 of these batteries to my son’s Razor MX350-24v bike. They were wider side by side but made them fit on same plate old batteries were on. My son now rides his electric bike a whole lot longer and same battery charger works to charge it. Also changed throttle switch. Nothing else. These batteries are worth it. Haven’t had any problems so far. Have had them only for about a week and used everyday since arrived with no issues. They came packaged good. Old batteries were 2-12v 7ah. These are well over that.

    I was concerned about the many reviews that said this batter will not fit the GoalZero Explorer 150 battery pack but went ahead and ordered it anyway. All I can say about those that say it doesn’t fit, is that they either got a different battery or really didn’t try very hard to insert the battery in the case. I’ll admit that it first appears that the battery might not fit but all you need to do to get it in place is to gently spread the two parts of the plastic case a part just a bit and then apply a couple of slaps with your hand and it will slide right in. I’m guessing that GoalZero designed the case to fit tightly so that the battery does not move around when it is being transported, etc. I just received this and haven’t had a chance to use it but will be going on an extended camping trip over the next few weeks and will update the performance after I return.

    I was a skeptical about the quality for time of use for this battery but I am very satisfied about having a 20 to 30 minute long (on average) driving session with my kids going up and down a 15 foot long steep hill and flat yard. I had to modify the vehicle’s wire harness using a old battery connector to change the connection to a typical spade style for this battery. The modification was expected to be done and not a problem to enable the use of this increased capacity battery. I will buy another battery in the future for other projects and to have a extra battery for the truck. The PEG PEREGO factory style battery was 12AH and cost more than double of this 15AH battery.

    I bought this battery for Wagan 2485 Power Dome NX (car jump starter and air compressor) as it is the same size battery and has same specs. The only problem was the battery connectors, the original battery had a RING terminal and this battery has a TAB terminal. Since it was hard to find a battery for my power dome, I just soldered some connector adapters I had handy and made it work.Other than that, the battery looks good quality and the rest I will find out in time.

    Purchased for a Razor MX650 electric dirt bike. Works very well, and fit nicely in place of older 12mah batteries. The main trouble was that the original batteries were soldered into the wiring harness, so I had to cut the wires to remove the old batteries. I then had to install crimp connectors on the end of the wires, which would connect to the new batteries. It would be nice if a wiring harness was included with the package, which would have eliminated some or all of this hassle.

    Excellent battery. They fit perfectly as a replacement for my original batteries in my Lynx L-3 mobility scooter. They significantly improved performance over the older batteries; I have a run I make nearly every day which is about 1/.2 mile long and most of it up a fairly steep (for a mobility scooter) grade. Even when new the original batteries tended to deplete some by the end of this run. Not the Mighty Max’s. I suspect the issue here is discharge rate and the Mighty Max does a great job there. I would recommend most strongly.

Excellent
Mighty Max Battery
Based on 5395 reviews
Received promptly very well packaged. I didn't see a request for the photo till after I installed them in my ups so here is a picture of the empty box and all the padding that they came in.
Battery works great. Bigger than original battery that came up as a replacement, but was still able to use it.
Very happy
Quick delivery and charge time. So far they have been great. Upon installing them hadca brief power outtage and they held up nicely.
The Mighty Max YTX7L fits perfectly in a Predator 3500 RV generator. Works Great!
The battery fit perfect. I did have to add F2 connectors, but that's not because of the battery, it's because my lawn mower battery exact replacement is discontinued. It's been working fantastic for 2 weeks now.
First day since receiving the battery. I am anxious to have it work. I have been without my APC for two weeks, and my Synology servers are disappointed in me.
Just received our MightyMax (ML5-12) security system battery and installed it in under one minute with no tools required. Looking forward to the same good service as our past experience.
Ordering was easy. Arrived within a few days. Installed easily.
Very good and quality, would recommend to anyone. The price is affordable compared to the quality received, and the package is good as well.
