Next message: Bob Hinely: "TWL: RE: Spider Droppings"
Well, 390 minutes at 25 amps would be 25*390/60 amp-hours or 162.5
amp-hours.
110 minutes at 75 amps would be 75*110/60 or 137 amp-hours.
The reason these numbers are different is that battery capacity is not
linear with load, i.e., if a battery will deliver 1 amp for 100 hours it
won't necessarily deliver 10]0 amps for 1 hour. Higher currents decrease
the total energy available from the battery. I believe batteries are
generally rated at below 25 amps, so that the first number would be a
conservative estimate of amp-hours.
