ML12-12 - 12V 12AH F2 Razor Battery fits MX650, W15128190003 - 3 Pack

After 3 years the batteries on the kids Razor MX650 motorbike stopped charging. I was afraid we'd have to scrap the bike when I found these online at Walmart. When the batteries arrived we pulled out the old batteries -- no small feat as there's a lot of plastic in the way and screws to the bars holding in the batteries are not easy to access. Next we discovered that Razor had soldered the wires directly to the original batteries, but the new ones had really nice slice connectors. We cut the batteries loose and replaced the ends with slide on connectors and reconnected all the batteries. Recommend taking a picture of how the cables are connected in series to make it easier. Everything was a perfect fit and we let it charge overnight (per the original instructions) before taking it out. The boys say its as good or better than before and they are thrilled to be riding again.
