2006 Accord Tourer petrol auto 2.4 Vtec. Owned for over 12 years and a great car!
I was going to write a long saga about trying to find out why my 2006 Accord 2.4 petrol Tourer's battery had suddenly started to go flat (only 3V!) after 3 days of non-use but this is the "long story short" version. I replaced the battery, as it was elderly and looked "weak" on my battery tester, but the new one showed the same problems.
With a 10A meter replacing the battery negative lead to chassis I checked the leakage current with everything switched off. There was around 255mA flowing continuously with a surge every 30 seconds to 450mA lasting about 3 seconds. A search of Google suggested 30 to 80mA was the norm for such leakage currents (I had not found this forum at that time!). I removed, one at a time, every fuse and relay I could find under the bonnet using the diagrams in the Owner's Manual. Nothing made any difference to the current or the surges. I tried the interior fuse panel by the driver's ankle and apart from the light in the driver's door (on because I could not get at the fuses with the door closed), pulling each fuse in turn, nothing changed the current or the surges. Now what???
Then I found this forum (I should have looked first you may say!) and spent several hours looking for battery leakage or quiescent current topics. What I did find was a lot about the Hands-Free Telephone (HFT) system with one contributor ("Gerryf") saying that faults with the HFT could cause "parasitic current drain".

That sounded encouraging! Today I disconnected the HFT (using the very helpful description and pics of how to access the module) and the current drain instantly fell from 255mA to 37mA!!!!
I do not believe in taking phone calls while I am driving so the HFT has not been used in the last 12 years. I shall leave the module in place and leave the connector out!
This could be a BIG RESULT! I am so grateful to this forum and the many contributors whose words I read! Thank you all so much.
Having had the car for 12 years and never before needing to look for a forum, I hope that it will be another 12 years before I have to search for your help again!
