    Seems good. Charged up but I haven’t undertakes it yet because I’m not sure if it’s safe to with this crack. I’m guessing it should be alright since there’s no liquid.

    This battery has 210 cold cranking amps,and the stock one only has 120. This one weighs 1.5 lbs, and my stock battery weighs 6.5 lbs. They are the same physical size, but the mighty max weighs 5 lbs less, and is way more powerful. Win Win!

    Weighs almost nothing, super low discharge rate, great price. Fits the size of a stock battery so you dont have to have foam fillers to keep it from bouncing around. It also has a built in meter so you can see the charge level.

    Perfect fit in my 1995 TRX300EX Honda. I like the fact that I didn’t need to use pads around the battery case. It is lighter than a 210 CCA Shorai that I bought 6 years ago for my Suzuki DRZ400S. The battery posts on the Mighty Max seem to be a little stouter than the ones on the Shorai. I am happy with the battery. I haven’t had it long. No problems.

Shipped fast and easy. Perfect fit. Thank you Mighty Max.
Nice replacement, same size, nicely packaged and fast delivery
Purchased two batteries ML9-12 SLA for a Cyberpower unit CP1500AVRLCD to replace old/exhausted OEM batts. The new ones were easy to replace and are a direct replacement and perfect fit of the OEM batts
product showed up in two days and they were fine condition.
I ordered a battery through Walmart online. My mother ordered it for me. It came in 3 days. It started right up. It made my 150 cc moped run so smooth.
