To help you, and everyone else out a little. If you’re of a mind to do it again, note the starting and ending voltages of the battery. End voltage would be nice to see done with load and no load voltage. Also nice would be to learn how many milliamps were replaced in the battery to bring it back to full charge state afterwards.
If you don’t have the tools to establish load, a mention of the aircraft type with it’s payload and how it was flown would be helpful for many. Current load is of critical importance as the load determines how long the battery will last. A 6300mA battery used to fly a multirotor might last 15 minutes before reaching critical depletion under a 3 or more amp load but the same battery used to power another device continuously at 1 amp or less would last for an hour or more because of reduced current load.
