MIL-STD-461, like every other such standard, requires that the test sample be tested the way it is used. In the case of a battery that means being charged, or discharged. So the test had the battery charging until full, then discharging until a certain potential was reached, and then charging again. At all times a permanent magnet moving coil (d¹Arsonval) meter was used to monitor both battery potential and current (charging or discharging). Ken Javor Phone: (256) 650-5261
