2002 draining battery at night

Don't know if this has already been discussed...my battery on my 2002 retrobird is draining while in the garage...no lights remain on except the red blinking diode on the dash...doors trunk and hood are all closed...it doesn't make any sounds. Is there a switch somewhere that has notoriously been draining batteries or is this something new.

You can disconnect the battery and check it in one day to see if it is drained, it could be the battery even if it is new. Good luck and let us know the result.

Could be something else, even battery itself, but when i first got my 05 it would not last 2 days of sitting.

Turned out to be the defective REM - rear electronic module was causing intermittent but often huge draws that were taking battery down

It is located below collapsed convertible top

It was then replaced and been fine since .. although battery, brand new just before the problem, lasted only 3 years - Mechanic figured battery life was hurt by the previous excessive draw problem

The security system (the red blinking light) on these cars is notorious for draining batteries, especially ones that aren't fully charged. Since it's in the garage can you leave it unlocked?

I left it unlocked...started it turned everything on then off and turned the car off...didn't help. I didn't hear any clicking. I disconnected the battery

How much was that REM ??
 
I burned through two batteries when new 2005, it took three years and several jump starts, a week in the dealership. Much deduction and replacement. It was the battery. Something special about them, the third lasted 5 years. I bought a voltmeter from Walmart that plugs into 12 V outlet on center console I use to monitor. Using that, never been a battery failure, 10 years.
Pretty annoying first week of ownership, in the cold icy weather for the tow truck.
 
You may have a charging problem. The battery may not be getting full charged by the alternator so it runs down overnight. It also possible that the battery had a weak cell and can not get itself fully charged. This can happen even with a brand new battery.

What to try? If you can hook a volt meter to the battery, engine running you should see the battery getting charged by the meter reading a little above 14vdc.
The battery it self can also be tested at a battery retail store.
 
Several ways to check this problem. First put a volt meter on battery with car running, all
accessories off, should see 13.8 volts or slightly more. Second with car off turn headlights
on, voltage should slowly drop to about 12.6 volts and stay here for 10 minutes or so.
Third thing to do, disconnect battery and put an amp meter between positive battery post
and battery cable and see what your amp draw is with everything off. Should be 100 or so
milliamperes. If more start pulling fuses to see where the draw is coming from. That will
help pinpoint where to look.

This may seem "stupid" but .... I was having drained battery problem. Had to call AAA for jump start. Mechanic said let me check the light bulbs for your map lights in the rear-view mirror. Sure enough, both of them were dead and the switch was on. He said his cousin had a Tbird and the map lights kept draining his battery. Absolutely no problem since he changed the bulbs for me!!

I recently had the same problem and found that my map light was remaining on. Several others had had the same problem, and recommended dialing down the dashboard lights and the time that they remain on after the car was parked.
 
Had similar issues (as do many others) - The battery finally died at which point I found out that the previous owner installed an undersized/off-spec battery (check this out in your car). A few months after replacing the battery I again had a problem at which point I discovered that the alternator was also failing and needed to be replaced (also have this checked out). This of course was a key reason, for the battery drain. But because so many people have had this problem, and because I don't drive the car on an every-day basis, I also checked and rechecked all the other usual "battery draining" suspects - including making sure that there were no dead interior bulbs (and it's not a stupid thing to do!). Because I still don't trust that I could let the car stand for several days at a time without a problem I decided to buy a battery tender which I routinely connect when I return home from a drive. Although I suspect that there may still be some other obscure underlying issue(s) that can cause a slow drain (e.g., the on-board computer not shutting down), the battery tender keeps the battery fully charged. After ruling out everything else, I would highly recommend this very useful device that comes with a quick-connect cable making it pretty hassle-free to use: https://www.amazon.com/dp/B00068XCQU/?tag=thunderbirdforum-20. Good Luck! Mike

Some new batteries are defective from the start. I once had a DieHard that died easy within months of installation.

Thanks for all the info folks...I haven't fixed it yet...but about two weeks ago I was using birdie as an outdoor boom box...I went to start it and it just clicked...I brought my "escape pod" around to birdies trunk and gave her a jump. I charged the battery and the next morning birdies alarm went off...not enough juice in the battery to start her. I closely scanned the info I received here...every time I dis and re connected the battery the alarm would go off and the radio would turn on even when I made sure EVERYTHING was turned off when I disconnected. I pulled the fuse for the radio and voila it stopped draining. Now I read something here that said birdie wouldn't be able to "sleep" now. Or at least not sleep properly. I'm on a fixed income (broken really) and won't be able to replace the radio right away...is there something I should do??? I'll leave the radio fuse out...anything else??? Thanks again...I really DO appreciate the input I received here. Threebird
 
Bonjours
J'ai eu aussi un problème de batterie qui s'est déchargé rapidement et j'ai envoyé l'auto chez un spécialiste
de problèmes électriques
(LOGIQUE AUTO)
Il a trouvé le problème
Il y avait un système anti vol pour localiser le véhicule dans le cas de vol (BOOMERANG)
Le système boomerang était en panne et énergie de la batterie.
Je n'ai pas acheté l'auto neuve et ne savais pas qu'il avait ce dispositif.
Il a été enlevé le système boomerang et je n'ai pas eu de problème de batterie depuis
Le système boomerang peut être dissimulé n'importe où ou dans le véhicule
Salut
