I have a small battery that is rated at 12.8V and 6.4 amp hours. Suppose it is connected to a 12V motor that is rated to draw 1.25 amps. 6.4 amp hours divided by 1.25 amps equals 5.12 hours and indicates that is how long it will operate at continuous discharge but info on the battery indicates it will shut down when the voltage reaches 10. That, to me, indicates that voltage drops while the battery is being discharged, or does it(?) since when I use this same battery on my dry washer, that motor (no specs available) does not slow down as an indication of low battery, it just suddenly stops running. I was told that was what would happen. Any idea how long it should actually run a motor rated at 1.25 amps?
