Question about 2006 Toyota RAV4
My battery went from fine to dead in 1 hour. I have a "good ear" for low batteries, so this really took me by surprise.
Situation: I parked my Rav4 in the garage and :45 minutes later, it wouldn't turn over. No headlights, and the interior lights barely came on; not even enough power to turn on all the warning lights that show up when you first turn on the key. I first thought of my headlights, but they were off, and it was daytime.
I then checked the voltage with my Fluke voltage tester and have 12.83 volts. So, I figured I needed to clean the battery posts and connectors. Still won't start. I pried off the battery caps and checked the water level. It was good.
I finally hooked up my gell "battery jumper" and gave myself a jump start. Started fine. I only idled it for 5 minutes and turned it off. Tried to start it, but it wouldn't start. Then, I hooked up my charger, and the battery won't take a charge either.
Is it really dead?
1. Is there some sort of regulator that prevents a Toyota from turning over on a low battery? I didn't get the expected 'buzz' noise that I was expecting.
2. I used to drive my Rav daily and now only drive it few times a week. Could that be an issue?
3. Can I check my charging system myself, with my fluke? and where would I touch the pos and neg testers?
Answering your questions in order:
If a battery charger isn't handy, try hooking up the jumper cables and leave the other car running for at least 15 minutes. I hope this answers your questions. Best of luck.
