dead battery no computer

[janprimus]

I left my key on yesterday and did not find it until this morning. tried to jump start my 2005 gs and I am getting no display whatsoever. Am I up that old fecal waterway or do I just need to get a new battery?

Try a charger. If it's the original battery it's time to replace it anyway.
Good luck

WAG - battery. Not unknown when they fail..

It is probably going to take more than a maintenance charger to stand a chance of recovering one that is as discharged as this is likely to be.

If its original I doubt one this old would pass a load test after a recharge anyway.
A load test is the only accurate way to tell if a battery is any good. Voltage measurements tell little about available cranking power.

Speaking of killing old batteries, I left the rear compartment light on in my 1995 SAAB turbo for a week and killed the ORIGINAL fifteen year old battery deader than a doornail. Jump started it from my pickup and drove to town (35 miles each way). After two days the battery is doing fine but I'm thinking seriously about taking it out and putting it in my tractor and buying a new one for the car.

You might try an Optimate 4 on it. Some report complete revival of the battery after two days on this unit.

Yep, I've got one. It revived a old lawn mower battery. Good stuff.

Depends on whether jump starting the tractor is easier than jump starting the car.

Paul;
I park the tractor on a hill and I can coast start it if necessary.

Were good!

It is an Odyssey battery. I read on their website that if the battery is totally discharged, a trickle charger wont do it. You have to put them on a serious charger so I took it to my local dealer and they charged it for me and it did the trick. It is holding a charge and I am back on my favorite bike! I actually had to ride my Yamaha Roadstar for a couple days and it reminded me why I bought the BMW! Within two blocks I was scraping my footboards again.
