I prefer kWh listings over amp hr listings
Amphr listings are for a constant current draw, But the voltage keeps dropping
20 amps @ 12.7v is more watts than 20 amps @ 11.5v
And the draw down test goes to 10.5v
So while the amps are consistent the power used aka Watts, is not
KWH ratings give a truer rating of total power capacity
