Mighty Max Battery YTX12-BS -12 Volt 10 AH 180 CCA Rechargeable Maintenance Free SLA AGM Motorcycle Battery

So far so good. You can't beat the price. Fit in my 2014 Vespa GTS300 with no issues. Fired up right away. No need to charge before using. The last battery I bought, you had to fill with water yourself and charge overnight before using, and cost twice as much as this one. Read more

Battery went dead, immediately after talking to support received a good solution Read more

I think you’re getting plenty of battery for the price. I’ve only used these batteries for my four wheeler in freezing Ohio weather. Each one has lasted years. If you keep a battery tender on them, they go even longer. Battery comes super well packaged! Thanks mighty max for making an affordable battery that lasts. Read more

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. Read more

I purchased this battery (YTX12-BS) as a replacement for the one on my 2016 Vespa 300GTS scooter. It fits snugly but perfectly and has excellent power for starting the motor. Shipping was ultra fast (same day!) and I was riding the scooter within a half-hour of delivery. Just a note - the included terminal bolts are just a little bit short so you may have to wedge something under the nuts to lift them up to engage the threads on the bolts when you install the wiring terminals. Certainly not a unique issue for this battery in particular, but just be aware. Otherwise this battery is an excellent value and I would buy it again. Read more

Just buy one if you want to spend as little as possible on a reliable power sports battery. Even much more expensive batteries do not compare. In the very rare occasion that something is wrong with a MM Battery the company will quickly remedy the problem. For the price what you get is amazing. Read more

Great so far. Extremely well made. Less than half the price of my last one I had in but the last one did last two years. No complaints. Read more

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 Read more
