    Just installed and works great. Batteries each had 12.95v out of the box and took about 30m to reach full charge after installed. If you want to use factory wiring read this! Have solder and hot glue available, or the right size clips. The factory MX350 wiring is soldered and hot glued to the terminals. You’ll need to cut off the wires at the terminals. At this point you can use the crimp-on terminal clips. However, the fuse cable is 10 gauge and my clips didn’t fit this. So keep in mind the size (10awg) if you plan to use clips. I’d also recommend adding the hot glue to help secure the clip and add some weather resistance. Soldering is preferred.

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.
Ordered via Amazon on 12/3/2025; arrived in 3 days.
Easy installation and charging as I am typing. Replacing in unit as shown.
