2002 battery drain, please help...

[bajuss21]

Hello, I'm so sorry for my language, I'm from Slovakia. I have ford explorer 2002, 3rd and I have a problem with draining of battery....my problem -
The battery consumption is 0.55A. Fuses in the interior:
3 (radio) - 0.14A - I have already disconnected
20 - 0.07A
17 - 0.08A
Engine fuses
29 - 0.15A PJB (I have no idea what it is)
1 - 0.14A
15 - 0.08A
18 - 0.07A
I'm desperate....when is temperature outside between 9-13 °C battery is absolutely exhausted in a few hours...thank you so much!

.5 amp draw with the engine off doesn't seem too excessive.

I thought I had an issue with parasitic voltage loss in my Dodge Ram. Turned out to be a bad battery. Have you had the battery load tested?

I agree with Rick, you likely have a very weak battery..
On the low end automotive batteries have 45-50 amp hours state of charge..
which means you should get 81+ hours of voltage from 45 AH battery before it falls below 10 volts..
