Mighty Max Battery Y50-N18L-A3-12 Volt 21 AH, 350 CCA, Rechargeable Maintenance Free SLA AGM Motorcycle Battery

After a long break, I needed a new battery to get my bike project moving forward again. Bought this Mighty Max battery and was glad to see it was nearly 13V right from the box. Fit was good in the bike, and b/c the carbs were all empty it took a while to get it turned over, but the battery never gave up. I cranked on it off and on for a while and it never got too low. Always rebounded great from key on to key off. Finally the gas got moving and it turned right over. Idled for a while, and now I have plastic to put on. Do like me: overcome your laziness and get things ready to ride again. Getting a new battery really got this project to the finish line and got me in the mood to get riding again! Two bikes down with new Mighty Max batteries, two more to go!

Battery seems good. The grizzly 660 2003 started right up didn’t have to charge the battery. The only downfall is like customers are saying is the battery connection it’s terrible but the best way to give you is they have these little flat nuts with rectangular connectors, so my best advice would give you is use electrical tape shovel electrical tape underneath the first put the bolts to hold the flat nut into the square box on the plus and positive and minus side then installed Electrical tape to keep the nuts in place because the batteries fit lay down inside the belly of the grizzly and then put electrical tape around the hole connector and everything worked out fine

I've been running this Mighty Max battery for a full year now and it has been great. I can't remember exactly which bike I put it in—I have a few dirt toys—but it has worked every time I hit the starter. For the price, you really can't beat the value and reliability. It's a solid, maintenance-free option that just works.

Going on 3 years with this battery. Doesn't hold a full charge without being used for a few days.

Works great ! 2004 Polaris Sportsman 400 4x4

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.

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.

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.

Su capacidad y función no le pide nada a las más caras

Estoy contento, porque la batería es exactamente para mi motocicleta, en bona perfecto
