Oh, please don't think I disabled that. I wouldn't even know how.

Not generally true for Li-Ion, though some manufacturers recomend it for LiFePo4 chemistries.
I inferred this from the Mugen instructions, which say:
"The first time, please charge the battery in the device for at least 8 hours ... After fully charged, please use the device until the device tells you the battery is verly low, then recharge. Repeat this process for 2-3 more times, where after (sic) you can recharge the battery whenever is suitable. Important: NEVER drain the battery completely to 0%."

That's a seriously defective battery. If the battery has been shipped empty, then it will have degraded seriously during storage and transport, to the point that it might even pose a safety hazard.
If you say so. But as I said, the original Nokia battery that shipped with my N810 wouldn't boot either in the same situation.
