The TI500 (Drager, Hill Rom, Air Shields, who ever owns it now) manuel we have says to check the battery by making sure it has charged for 20 hours, open all the hatches, turn on the light, up the heat and let her cook for 1.25 hours without the LOW DC alarm activating. I did this test yesterday and I think only one batt status LED went off after the 75min. This must be a typo in your manual.
Also, does anyone know where I could get a chocolate Teapot? Christmas you know.
