Hi Everyone,

I bought my 2007 TL Type S used about 2 months ago now, after about 2 weeks I noticed the battery would be dead or almost dead after not driving for 2-3 days. I'm pretty good with cars and Acura's in general so I checked the little things out like this:

Battery holds a charge fine
Alternator seems to be fine
No lights on in the car that I've seen

After reading a few forms on here I also saw something about he bluetooth not working and I actually did notice that mine always said " booting up " so I disconnected the unit last Monday and my car still kinda struggles to start when I turn the key.

This happened yesterday, I drove about 20KM and stopped for gas you would figure the car battery would be fully charged but it still kinda struggled to start which I found kinda odd.

I can't seem to pinpoint what the problem and I 'm reaching out to my fellow TL owners for help on this matter.

Thanks everyone Daniel

 

Alternators are not really designed to fully charge a dead or very low battery. Their whole purpose is really to just maintain the battery while the car is running. They are capable of fulling charging the battery, but it takes a lot longer than a 20km trip.

It sounds like the bluetooth was the issue, so try giving the battery a good charge with a real battery charger and go from there.

Edit: If you have already tried the battery charger, then see if you can get advance auto or autozone, etc. to load test your battery for free, or throw in a new battery to test. Sometimes a battery will appear to hold voltage fine, but as soon as a load is applied (the starter) it drops too far down to start the car.

 

recheck battery.
the HFL might have drained the battery so low that it might not be able to hold a charge.


or what he said above me! ^

 

I mean * draining not drying haha

anyways, thanks for the quick replays

Would anyone have any other ideas on what this might be or have heard of battery draining problems before

 

battery drained from HFL. you said you had HFL problems.


Did you check your battery like every suggested..??? Seems pretty correlated to me

 

Battery was the first thing I checked then I moved down the list..

I haven't had it checked after I removed the HFL but days before I did remove it the cells were fine.

 

A lot can happen in days, so check it again.

 

How did you "check" your battery?

you said the cells were fine.. you mean you checked the water levels...?

 

When you checked the voltage of the battery, where was it at? Also what year/month was the battery made? I'm still betting it's a bad battery.

 

This was happening to me very annoying, I removed the HFL. Its on the center(front) interior lights. You have to take off that panel with a flat head. Then you can remove it simple click and release. Ever since then i dont seem to have that problem anymore. Also you might notice you phone pairing not working one of the first signs the HFL is failing.
