New 12V battery was totally dead after 2 days

I have got a problem with my 12V battery because when I don't use a car; my battery was totally dead after 2 days.
I bought new 12V battery Bosch S4 022 and problem is the same. I checked power consumption when car is off and consumption is 0.8A (800mA). I know consumption should be less than 0.05A (50mA).
I removed every single fuse below steering wheel and consumption is still 800mA and my battery is going down 16 times faster than should be.
Any ideas how can I find a fault?

 

Yes you are right I am from Suffolk in UK.
I never installed alarm system but last owner maybe did it.
Light in the boot is turned off and all doors closed. All internal lights are turned off. I checked internal fuse box only but I will check second fuse box tomorrow (under the bonnet). I hope consumption go down when I remove one of fuse.
I know Audio System (Radio) sometimes make a problem and there are 2 Audio System fuses under the bonnet (38. Dome 15 A Fuse and 44. AMP 30 A Fuse). I will start from them.
I have got one more question: If key fob is 2 meters from car can discharge a battery (No smart key system).
Thank you for quick response.
If any other ideas please let me know.

 

My Prius II is the cheapest T3 model. All lights include the vanity mirrors behind the sun visors are turned off when I checked power consumption. It is 0.8A immediately after shut down and 1 hour after shut down. Please let me know how long time Prius (after shutdown) needs to go to be in asleep mode?. When I open a car by key fob is still in asleep mode or is not?

 

Thank you for reply. I checked my battery voltage and is 11.88V in this moment and probably tomorrow morning will be dead.
I removed fuses under the bonnet. When I removed fuse number 38. DOME 15 A (Audio system, Interior lights, smart entry and start system, gauge and meter, turn signal lights, luggage compartment light, clock) consumption of power go down to 0.2A (200mA).
When I fit it a fuse again consumption back to 0.8A (800mA). I know 200mA is still too much but is absolutely satisfactory for me.
I think to check as a first Interior lights and luggage light by remove all light bulbs.
I really need your help. I hope we sort it out together.

 

Thank you.

 

Thank you for reply. I will remove them tomorrow morning. If I do not find fault with bulbs I will try cut off Audio System but I am not sure how I shoul do it. I know about 4 fuses to Audio System 20. ACC 7.5 A, 16. Panel 7.5 A, 44. AMP 30 A and "lucky" fuse number 38. DOME 15 A.
I will remove 3 other fuses together (I leave just fuse 38) and I hope Audio System will be cut off. If you know other way to cut off Audio System (I have not idea how can I take out a radio) please let me know.

 

Thank you for help.
I am studying prius wiring diagram just now.
I found wiring diagram as below

This is 2004 prius diagram but I am sure is the same as 2007 prius.
I am not an expert but maybe we figure out together.
I will contact to you tomorrow.

 

I am not sure which one is IG2 relay and which one is IGCT.
I do my best to find them.

 

I try pull them out but all relays are dificult to take out and I am worry I can brake them.
I will make a risk anyway but I will be graeteful if you let me know which exactly relay is IG2 and IGCT.
We have got 9 relays in total.
1st top row are ABS NO.2 green (small one)
2nd row ABS MTR 2 blue
3rd H-LP grey
4th DIM light blue
5th row P CON MTR grey, FAN NO.3 light blue(small one), FAN NO.2. red (small one),
6th row ABS MTR blue, ABS NO.1 green (small one).

 

I found relay location.
IG2 - is connected with fuse 30. AM2 15A
IGCT - is coneccted with fuse 32. HEV 20A

 

Problem is partly sort it out. I removed (IG2, IGCT) 2 fuses from relay B (FIRST RIGHT TOP RELAY) than I connected Multimeter and power consumption was 800mA than I closed a boot door and I activated alarm by fob key and after 5 second consuption was still 800mA than I almost give up but power consumption go down to 150mA. I was sure relay B needs to be replace but I was wrong. I fitted fuses to relay B and I checked PC again (same way) and I discovered when I close door boot and activate an alarm by first 10 seconds PC is 800mA and than go down to 150mA if bonnet is open when bonnet is close alarm needs 10 seconds more to activate (I do not know why).
I think my electricity works fine but I did not check PC properly because I did not know I have to activate an alarm and than wait about 20 seconds. In my opinion my 12V battery is discharge quickly because is Bosh S4 022 12V Car Battery should not be fit it in Prius!
I bought this battery on eBay follow item description: "This item fits 12 version(s) of the Prius".
I need to buy another New 12V battery.
I hope I am right. Please let me know best quality battery 12V to Prius. Maybe start-stop gel one? Please let me know model details.
If someone used Bosh S4 022 12V Car Battery please give a feedback for this battery because my feedback in negative.
I would like to thank to Britprius because I never sort it out without his help and support.
