'05 TL Battery Drain

'05 TL Battery Drain
I own an 05 TL no navigation. I have been through 3 batteries the last 12 months. It appears that if the car is not started for several days the battery drains. The car is currently at the Acura dealer. The service rep told me they charged the battery and found no problem. She also said it is normal for the battery to drain if it sits for 4 or 5 days. Can this be true? I find that very hard to believe. If it is true, it’s is unacceptable, going to have to find another ride.
Is this normal?

I also have an 05 TL. I had my battery replaced under warranty about 2 or three years ago. I've had the car idle for one month without any issue since then. However, I had to replace the battery yesterday. I am out of warranty. I did it at Autozone because I don't trust the batteries the dealer sells.

I got my car new in the middle of 06 and had to replace my battery at the beginning of 08. I thought maybe it was the cold NY winter that may have put a strain on the battery. I took it to a local shop and they tested the battery and alternator at the time and they showed me some printout that showed inconsistencies in the alternator output and it wasnt recharging my batter correctly? (sorry not mechanically inclined)
I then took it to the acura dealership and asked them to do the same test but they found nothing wrong and assured me the batteries have a limited lifespan.
now thinking back at it i think they MIGHT have gave me some BS because the car was still under warranty, or maybe the local shop was BS'ing me ...
I changed my OEM battery w/ an interstate battery at the start of 08 and low and behold as soon as some cold weather comes in this year, im noticing the same symptoms i had 1 1/2 years ago.
has anyone else replaced 2 batteries in a little over 3 years?

Man I swear...your problem is exactly what I am going through right now. Replaced battery under warranty year and half ago. Now that sucker won't hold a charge overnight. I'll take it to the Dealer to make sure there isn't anything else wrong. Any good recommendations for a replacement?.....no dealers please

acura batteries suck! Your best bet is to get an aftermarket one that'll last longer and have a better warranty, plus it's cheaper!

The car was not started for 4 days, battery remained strong. Looking good. I suspect the HFL being the culprit. Stay tuned!
Anyone know what the normal battery current should be when car is off?

it should be drawing about 25-30 milliamps when the car is off. To figure this out, set it in a series with the positive terminal of the battery.

I bet it is NOT your battery. My '07 TL was going dead too. Based on info I read on this site and others I narrowed it down to the Bluetooth Hands Free Link. Took it to the dealer and told my problem and had them check that out specifically. They checked the battery drawn with everthing off (as off as it gets). Something was still drawing too much power. When they unplugged the HFL, the batterey drawn dropped to normal. They are replacing my HFL under warranty.

nfn,
thanx. but i can't see the file, hovvevefr, i am in here specifically due to being on my 3rd or 4th battery.
just got a del sol beater, and car is garaged using a good battery out of a '07 rx-8. battery dropped to 12.6v and still dropping. even my battery tender can't bring the charge up... vvhat gives?
let me knovv if this is a free of charge adjustment on the HFL( novv i knovv vvhat HFL means) and maybe i'll tell my vvife to turn off her bluetooth setting.

Have you had your whole charging system checked? Could be an alternator...

The battery needs to be a group 24F battery. I tried the Optima yellow 34 78 something... dead in 3 months, I brought it back from the dead with a solar charger. This battery needs a longer time to charge than 24F batteries while the engine is running. So if you're taking 15 min. trips or shorter this battery is not your best choice. I got a group 24F Exide battery from Home Depot and so far I have 10 months and it looks like a good battery. I make a 20 - 30 min average trip everyday. HFL is disconnected even tho it's still running good. I found that isimple has a 165ma current draw when the car is off so it went to igarbage. I see the memory driver 1 LED on the door it never goes off after the car is armed unless you change a seat setting but that's no biggie. Other than that no major voltage draw.
