Battery draining info help
So I rebuilt my power steering pump on my 04 Acura TL yesterday and left the trunk open for about 4hrs and when I go to start the car after I have everhbing finished it won’t fire, dead battery symptoms, had to jump start from my wife’s car with jumper cables, also few weeks ago I was cleaning the inside of the car out and and had the radio on and ignition on but car not running and the battery was dead within 1 song when I went to fire it up! Any ideas if this is normal? Battery and alternator testing normal, the car does have an aem CD player / radio Bluetooth etc and I think it has aftermarket speakers cause there’s wires coming from there then into the engine somewhere, must be spliced into the battery leads somehow NOT sure... I can get pics, not sure if this helps but also o believe someone removed the navigation screen and replaced it with the other one (Canadian model it states in the manual) and only can see the ac on or off not the bottom screen doesn’t work.. any thoughts ?

If 3 years or more, it's probably the battery.
If newer, look for a drain 30 minutes after shutting off the ignition. The two major culprits in stock 3G TLs are a bad HFL unit or a bad A/C clutch relay. Check for draw with a multimeter at the interior fusebox; this might be best given your car's custom wiring work.

How old is the battery?

Had a similar problem with my acura rsx 05. Put a voltmeter on the post and got a good 12.5 - 13 volts. Then I put my battery tester on. It connects to the bolts on the clamp, it only read 5.75 volts. Then I had a light bulb moment. Clamps were tight but when I took them off then I could see a layer of oxidization. Cleaned them up and all is well. My car would seemingly die after 12 hrs of being on a charger. I would put the key in and when I turn it everything would go completely dead, couldn't even take the key out of the ignition.
Cleaned the posts...all's good now. Might be worth a try.
