Answer 1

P1225 is not used for this car, try to use a different OBD-II reader the one you used might not be compatible with your car. If your battery light is coming on the alternator should be checked.

 

B1813 is related to the air bag system the wiring will have to be checked 

Answer 2

B1813 Short in D squib circuit

This code condition is for the Airbag system, which does not cause the condition that you have in dead battery, Majority of Toyota owner have this code condition for the airbag. You may be dealing with a poor battery terminal connection, For the batery to die so soon when when the key is off, this can be from a relay staying in the on position when the engine is off and key is out.
