Ummm, all you did was restate and verify what the grandparent originally posted.
1000 batteries * 1.5 mW per battery = 1.5 W
check.
1000 batteries * 1.5 V per battery = 1500 V
check. (for batteries in series)
1.5W / 1500V =.001 Amps = 1mA
P (watts) = V (volts) * I (amps). Therefore I = P/V. check.
The grandparent post's calculations are correct.
