This problem relates to the battery which was purchased 5 months before the incident. While riding my motorcycle down the freeway I lost all power (lights, engine, instruments, everything) abruptly and unexpectedly. This nearly caused an accident. A couple hours later the bike started with full power. I decided not to ride it home and left it in a parking garage. Over the next couple days I tried to determine the failure, but it was intermittent, sometimes the bike had full electrical power and the engine started normally, other times no power. Of course I checked the battery cables first. The screws were tight, the cables were secure. I didn't suspect the battery and was checking other things like fuses, stator, and ignition switch, and so on. While riding around the garage with the seat off, and the battery exposed, the bike died again. I quickly probed the battery and found 0V. A couple of minutes later, is restored full power and the battery again read 13.1V (I took pictures). Such behavior is odd for a battery but this is a complicated, and expensive lithium battery with internal electronics. It is the ATZ-10 ReStart 360CA battery. When I called Antigravity (the manufacturer) I talked to the call center, and a manager of manufacturing. They claimed to have never heard of this. However, when I looked the battery up on Amazon reviews, other people reported the same problem for the same battery. I purchased a different battery and the problem is gone.
