That's because your battery is rated at 500mAh and not 500Ah. For the purposes of that calculator your battery capacity is 0.5 Ah. Discharge rate is 0.0135 Ah. This gives you a safe 80% discharge time of 43.784 hours.

A Lithium rechargeable battery cell must NEVER be discharged lower than 3.0V or it is ruined and might catch on fire.
Lithium cells in products have an attached circuit that disconnects the load when the discharging voltage drops to 3.0V.
A Lithium rechargeable battery is 4.2V (which must be regulated by its charger) when fully charged then the voltage slowly drops to 3.0V as it discharges. Many loads are resistive and drop their current as the voltage drops (a light dims or a motor slows down).
My electric RC model airplanes have a circuit that pulses then shuts off the motor when the voltage reaches only 3.0V. Sometimes the airplane is flying slowly at a low current and I don't notice or hear the motor pulsing then the battery is destroyed.
I wanted to delete it yesterday,but i didn't know how to do.
i'm sorry for my rush...
Yes, Li-Ion battery discharges till 2.75v(someone say 2.5v) and charges up to 4.2+/-0.02V. i didn't consider of it
In battery pack there's protect circuit.
Thanks to all of you for your help. 43 hours isn't all that bad really. I was hoping for more but maybe having it off every 30 seconds will prolong that time a little more instead of being on 24/7.
