Is there any answer - MY03 STi Flat Battery Problem??
#1
![Question](https://www.scoobynet.com/images/icons/icon5.gif)
Happened again to mine just now, 3 days unused & completely dead!
First time a new/better battery was fitted at the dealers which improved the general hesitant starting but this has gradually returned.
Car is 100% brilliant apart from this but it's a touch annoying!
Has there been a definitive answer as to how this can be put right? (If there is my dealer is unaware of it), otherwise might have to invest in one of those trickle charger things.

Steve - seems like it's perhaps a combination of a duff batch of batteries and/or the tracker continually drawing current....

Mmmmmmmmm, couldn't access search function earlier, but it would seem that it's likely to be the alternator/tracker/battery, any one or a combo of all 3! The new(er) battery suggests the former 2 as the culprits maybe.
Is the trackstar testable? If so by whom - dealer or RAC?
Steve
PS, the rest of the car is spot on unlike Elmers!

mmmm more like it needs charging for 6 hrs at 1/10 of an amp before fitting then it may have a chance as the new charging system will never put in any more to the battery then was first there

i got my battery replaced and no problems since then,dealer said it was a known problem due to batch of batteries-check code with dealer and get them to keep it for a few days and see if it is a charging problem

Steve, there's been many theories about this problem as you can see. When mine went the most popular culprits were a dodgy batch of batteries, but as many people have had repeat occurances with higher spec units that one's ruled out. The alternator overcharging, suggested cure was to leave sidelights on to create a small continuous drain, which I have done ever since. A dodgy foglight relay, had mine done along with my new battery and so far so good (15th may 04).
Are you coming to the next WYIOC meet, or do you fancy a coffee in between ? Haven't seen you in a while.

had mine changed and still flat if left for over 5 or so days
. Suppose I could leave it on trickle charge if i wanted as I just jump start it at present.

The tracker should go to sleep after 60 minutes and stop polling back, if not it will drain the battery.
Also running with the headlights on makes the alternator charge more.

This is what can happen.....
The donor cars engine is running, and you start the car with the flat battery, thats all fine. Then you leave the jump leads connected for a while.
When you eventually come to disconnect them, if the donors car engine is still running, its alternator is working Very hard to charge the flat battery on the other car. Suddenly that load goes away and it takes a finite time for the donor cars alternator to react to the change. That spike can fry your ECU. I have even known it to fire off the Airbags on a Mercedes!
There are expensive surge protectors available to prevent this, but most jump leads don't include them. I believe if you follow the instructions provided with the leads exactly, you may also be OK
But, my advice would be to never jump start, or offer anyone a jump start from a modern car.

just had the same problem, car left over x-mas & new year at airport carpark, tried to start it on our return - nothing completely dead.
its due a service this month so i,ll ask the dealer to check it out.
strange thing though the car park operators would only jump start, using a battery pack, the car after i signed a disclaimer to say that if it damaged the car in anyway they could not be held responsible

Steve
the times I have jump started the car, I get it started & disconnect the leads straight away. Just leave the car running / take for a run then to charge the battery.
Cheers 4 the info thou, noted

...as for my battery constantly discharging
My local main dealer(in the UK)reliably informed me that I had a Tracker problem.
in as much that when I garaged the car at night,the Tracker would then spend up to 7 hours trying to locate a sattlelite,constantly drawing so many amps an hour.
The fix was to contact the Tracker people,who will then come out to you and adjust the search time down to 1 hour.
Whether this is true or not,or if its whats causing your problem I don't know![Frown](https://www.scoobynet.com/images/smilies/frown.gif)
Just relaying what I was informed,Jon

If you use the super lock option it stops the alarm scanning for a radio transmitter, thus saving the battery, it worked for me over a 17 day airport stay.

OK, diagnosis from subaru assist is a duff battery, which has again been replaced FOC.
After speaking at length to trackstar technicians I reckon that whilst it's quite minimal, the drain from the tracker is probably compounding the 'smart' alternator inaction issue, with the battery being asked to supply power for that plus the ice, interior lighting etc etc. All small drains but none of which is enough to kick the alternator into life to replenish the battery.
The answer (for now) - drive with sidelights on all the time as a test at the dealers shows that this is enough to get the alternator active, so we'll see if that sorts it!

These sort of solar chargers could sort out the problem, but not the cause.

you say you have an 03 sti. mine has a battery volt indicator in the alarm system. the little red light by the clock will flash to tell you what the volts are. try checking that to see when you are losing power.
