No problem Greg I charge the battery without disconnecting it all the time. Just don't put it on to high of a charging rate. Ten amps for a couple of hours is great.GregC said:Is it safe to charge the battery connected to the car and if not what are the effects of disconnecting the battery if any ?
Thanks
Thanks,Rocket M5 said:no problem charging the battery with both terminals connected. But I do recommend you to put the charger negative cable to the vehicle's body(or any ground source). Just for your safety!
Sounds like a defective battery, Greg. Leaving the glovebox open will not do it. After 16 minutes of not touching the car it will go into "sleep mode" (consumer shut off mode) whereby it will kill the light in the glovebox until the car wakes up again.GregC said:Thanks,
The inspection light was totally dark as the battery had gone dead when I left the glovebox door open over night.I'm sure it must have been weak form it's winter snooze...anyways a roll down the driveway,clutch out and she started up immediately.I idled it for some 30 mins,then put the charger on her for 10 mins and the cahrged showed no current and the green "charged" light came. on...but...still no green light in the battery inspection hole.I suspect the unit is pooched...What's the warranty on the battery ? This is a 2003 car with only 16000 miles ?
Yeah Mike..I thought that too..But today now I know it's toast for sure.I idled it for 30 mins then it sat for about 1.5 hours and barely started..What are these things worth...should it not be a warranty thing?mdernst said:Sounds like a defective battery, Greg.

I would think it is a warranty item but I'm not sure. Check your warranty book?GregC said:Yeah Mike..I thought that too..But today now I know it's toast for sure.I idled it for 30 mins then it sat for about 1.5 hours and barely started..What are these things worth...should it not be a warranty thing?
Couldn't really find anything on it...looking still...mdernst said:I would think it is a warranty item but I'm not sure. Check your warranty book?
Idling won't charge a battery. You need to get the car out on the highway for at least 30 minutes to charge it up. Of course, putting a charger on it will do the same thing. If toast and not under warranty, do a search for a replacement of the same rating for a lot less than the dealer will charge.GregC said:Yeah Mike..I thought that too..But today now I know it's toast for sure.I idled it for 30 mins then it sat for about 1.5 hours and barely started..What are these things worth...should it not be a warranty thing?
Battery warranties are pro-rated. Depending on age of battery. I had to replace the battery on my old 540 (under warranty) I ended up paying about 50% of the pro-rated original cost of the battery. Better than paying 100%mdernst said:I would think it is a warranty item but I'm not sure. Check your warranty book?
