Pretty sure this could be an issue with a dead battery, but thought I’d throw it out there for other ideas:
I tried starting my 2005 Jeep Wrangler yesterday and there wasn’t enough charge to get it started. I got a few slow revolutions and that was it. I gave it a jump and it started fine. Drove it for an hour or so and then went to restart it 3 hours after I shut it off and it was dead again. Another jump and I drove it for an hour (home). I was able to start it a few hours after that on its own, though it struggled to a bit.
Tried again this morning and it was dead from sitting overnight. A few other bits of info:
- With the key in the ignition, the charge indicator is hovering just above 9V (it is a 12V battery) before I try to start it. When engine is running after start, it jumps to around 12V.
- I am pretty sure I didn’t leave the lights on or door open overnight. I haven’t noticed the engine struggling to start leading up to the dead battery.
- After I jumped it again this morning, it seems to be idling very low. In fact, the engine shutoff when I let it idle in neutral with my foot off the gas for a few seconds.
- When I got in the Jeep this morning before trying to start it, it had enough charge for the radio and dashboard. When I turn on the lights/highbeams it struggled and the high beam indicator on the dashboard (blue light) was flashing.
- Battery is not too old. I don’t have the receipt with me, but I think I bought a new one 3-4 years ago. The +/- connections are clean with no corrosion. I didn’t look too closely, but I didn’t notice any obvious connection issues from the battery leading into other components.
I’ll probably go buy another battery, but wanted to check with the experts out there to see if there is anything else I should be checking. If I do get another battery, would also appreciate any advice on things to check to make sure that is definitively the issue before draining it too.
