| Etymology | from Middle batri |
batra — a pile; plates of two metals stacked with an acid between them, giving a small steady current.
Notes
Runs instruments, never motors: chronometers, gauges, indicators and timing triggers. Plates corrode and acid is spent, so a batra is renewed on a schedule.
