Quick, get ahold of the engineers at Boeing! Tell them to switch to whatever they used on their older planes! Surely they haven't considered that idea yet!

Have you ever been in a situation where a manager proposes a technical solution that everyone else has already dismissed as preposterous? Now you know how it feels to be on the other side of that.

With that mockery out of the way, I'll give my understanding of the situation: The lithium ion batteries on the 787 are much smaller and lighter than their predecessors. They also take up less space and require different input and output voltages and currents. They have different charging profiles. Swapping them out with an older battery technology is infeasible. It would require redesigning other components to make room, building new transformers and voltage regulators, and writing new software to charge the batteries safely. It would also reduce the range, capacity, and/or efficiency of the 787.

I do apologize if I went overboard with the mockery. Please don't take it personally; it's fun to write.

You certainly do live up to your name there, Parsley.
