Mighty Max BatteryYTX24HL-BS -12 Volt 21 AH, 350 CCA, Rechargeable Maintenance Free SLA AGM High Rate Series Motorcycle Battery

Amazing cranking power in a small and completely seal package, came 90% charged. Don't buy a standard lawn mower battery, they lose their cranking power fast, this is far superior technology. Installed on a cub cadet 42 inch zero turn and now it starts instantly because of the increased cranking power. Can't comment on longevity because I just got it but Mightymax appears to make a quality product that they stand behind. Very happy with the performance of this battery, it was a great purchase, I recommend it.

I wanted to share my recent experience with motorcycle batteries. Over the past three years, I spent an extra $30 to $40 per battery each year on a box store brand, mainly because I didn’t have electricity in my garage to keep the battery charged with a trickle charger. Living in Ohio, I expected a battery to last through a winter, but I was left feeling underwhelmed by the box store option.After some enthusiastic research, I discovered Mighty Maxx, a highly rated alternative that is both affordable and seems to outperform my previous batteries. I decided to give it a try, and I’m thrilled I did! This battery is the same size as the one I used before, but it offers more cranking amps—both regular and cold. Right away, it started my bike effortlessly! I’ve only had it for a few weeks, but so far, it’s been absolutely reliable. I'm excited about this find and confident it will serve me well!

Great battery!!!Prime shipping delivered to my front door in less than 24 hours after purchase.It came almost 70 % charged. I only connected my trickle charger for 2 hours and it was up to over 13 volts. Amazing cranking power, I wasn’t able to ride for weeks but when I started back again it was like never lost charge.

Ordered 2 and they seem to be working fine. They have enough power to crank over fine and start pretty quick like normal on our 2 different 4-wheelers. No clue how long they’ll last at this price point but we’ll see.My only complaint is the company’s quality control because one of the batteries arrived in not perfect condition. The positive post was bent very close to being unusable. Both the company’s box and the shipping box were in perfect condition so the battery had to have been placed in the box with the bent post. I was barely able to get it bent back to a usable state and thankfully it was able to be used. I would’ve had it replaced but didn’t feel like dealing with the return process so I just fixed it best I could.Also the included hardware for attaching the cables was complete garbage quality, the anchor nuts spun in the posts and basically crumbled into pieces to the point I had to reuse the old hardware. Just so things to keep in mind if I decide on buying these again

Battery fits right in the holder on my Snapper tractor. I bought an AGM type battery as I didn't have to buy acid for an additional cost. Too seen to assess durability

Mighty Max battery can be mounted in any position. Easy to install, ready for power outages and hurricane season. Very powerful battery. I highly recommend

Seems to be a great battery for a fraction of the cost as the part stores charge. The terminals seem to be a little cheaper than other batteries but my wires hooked right up. My bike is hard to start because of the high compression and this battery spun it over like it was nothing. So far so good. I have used this brand before for my home alarm system and they always seem to have great batteries.

I replaced the auxiliary battery A0009829608 on my 2015 Mercedes CLA250. The cars eco on/off at stop lights kept dying completed and had to restart the car so then got Auxillary Battery Malfunction warning. It’s exactly the same size and fits with the cover snapped. Only paid $39.95 and MB online wanted $165 plus shipping. Looks nice and well packaged. The reason I didn’t give it 5 stars is because 1) it has no vent hole so the tube from the car can’t be used 2) the terminals are not a solid piece of metal that is treaded for the bolt. Instead it comes with two rectangular threaded plates and what should have taken me 5 min to change took me 30. First I thought the plate fit snuggly one direction but instead it is perpendicular and loose. Second as it is loose it can’t stay in place and under the dash is tight and goes in at an angle. I had to use my McGyver skills to wedge a rolled up piece of paper in each to push the plate and center it. Then once threaded a few turns I pulled the paper out. Worked awesome. TIP: remove the cabin filter cover before removing this battery.
