Prius (2004-09) :: Installed New 12v Aux Battery - Engine Won't Start
Dec 30, 2013
I purchased a new 12 volt battery from Toyota and installed in my 2009 Prius. My car wouldn't start. So, next I tried to jumpstart it. I pressed the Power button (the light was GREEN) but it wouldn't start. I pressed the Power button again (The light was AMBER) and the hybrid drive engaged and the CHECK ENGINE light came on; however, the engine didn't start, the dashboard didn't light up and the READY indicator did not appear.
Next, I grabbed the Owner's Manual and went through the Troubleshooting sequence. Engine still wouldn't start.

My mechanic installed a new Hybrid battery in my 2005 Pruis using the repair manual and a video that showed him how to do it. He also replaced the harness and the ECU battery. When he tries to start the car all of the lights light up on the dash but no ready light on the start button and the car will not start. The instructions did not say anything about this issue so he is lost! He thinks the smart key and the ECU have to be synced in some way but doesn't know how to do it.

I decided to install a new Optima yellow top battery because I performed the battery check and found the voltage low and therefore believed my 2008 was still running on the original OEM 12v battery. Much to my surprise I found a non-OEM battery installed and the vent tube elbow missing!

Just put in a new 12v battery but when I try to connect the ground cable, I'm getting sparks, indicating a current draw. And the horn starts blowing nonstop.

I just bought 05 prius from a dealer I don't know the history was told all it needed was a hybrid battery.
Now I have a 05 that I drive with known good parts so I pulled my hybrid battery and installed it in the new car the monitor showed engine charging inverter then going to the battery. However the bars on the battery graph start dropping. only code is a engine code 2102.
I also noticed the old A/C condenser in the back.

My car had a new bumper installed, and now they can't get it to start. When you hit the button to start, the red "immobilizer" anti-theft light blinks for a moment like the key is not in the car.
This is true even if the key is inserted into the dash. The remote key still can open and close/lock the doors just fine, so this is strange.
They did mention that they had to recharge the battery for some reason. I don't know why the battery had died for them, but it is charged now. (Headlights, etc work fine).

Tested and replaced 2 bad battery cells in my 2007 Prius... Got everything put back together and now all dash lights are on and engine won't start... When i try to shift into drive or reverse it goes directly into park... I tested the battery without removing the safety key and the inside terminals are at 220 volts and the outside terminals are at 0 volts as shown by photo... Maybe due to a fuse somewhere?

Over last two years have replaced a few alternators and (3?) batteries in my 2000 Solara SLE with 150,000 miles. However, In last three months I have had three additional alternators. Car wouldn't start, had it towed, and a mechanic put in new alternator and battery. Happens again, car won't start (now own a jump charger!), and the same mechanic puts in new alternator. Happens again and Mechanic #1 says he has checked it and its fine. I then go to my regular mechanic... Says its the alternator which is bad (when you put the AC and Radio on, it appears to charge for a while, but if you leave it running it will stop charging and then after a while it will go to overcharging and undercharging. I noticed when driving on highway my lights will brighten and dim).
He sends me back to the first mechanic because the alternator is bad. They put in a new alternator. I take it back to Mechanic #2 my regular mechanic to test it so I don't get stuck. He says its still doing the same thing. I tell him I will pay to have him put in the new alternator and he can own the warranty.... He sends me to a car electrical specialist. After having my car for 3 days the car electrical specialist just called and said in 30 years he has never given up but he has now. May or may not be related: My check engine light was coming on and I had mechanic put in new oxygen sensors. I also have intermittant traction light and ABS light coming on and the check engine light will sometimes come on too. My dash board feels like Christmas...

So my 2003 VW Passat will not start. I last drove it a few days ago, and it has been sitting inside a nice warm garage. The battery was replaced a few months ago. The car doesn't "turn over" but just has a steady sound when you try to start it. It's not a clicking sound like I had 6 months ago with it. I attached a link to the audio file of me trying to start it today. There are no warning lights per se coming on only the typical ones coming up when the ignition key is turned on. The lights and interior lamps come on indicating there seems to be power but nothing else. The plugs were cleaned a few months ago as well. Could it be alternator? I could try jumping it but the sound it makes leads me to believe there is plenty of juice.

I replaced the battery because I was getting the red triangle with no screen powerup. This is a slight improvement but I'm stuck as to what the "Problem" indicator on the MFD is about.
I've checked the battery in maintenance mode, reading 12.6V.

2009 Sonata 4 cyl with 40,000 miles.
My car was slow to start last night. This morning took it to Autozone and they checked the battery, which was bad. Got the new battery installed and drove about a mile then turned off engine. Upon restarting engine, Check Engine Light came on.
The timing is such that it seems the CEL is because of the battery. How to handle? My car has otherwise run perfectly in its first 40,000 miles of life. Only other relevant detail is that the presets on my radio kept resetting, I figured this may be because of low battery power.

I wouldn't do it myself, but I was wondering if it was even possible to have a remote start installed.

2005 Prius was dead this morning. I had left a light on a couple of days ago and had to jump it. It started right up. I only drove short distances in the next couple of days, so I thought battery hadn't charged fully. But when I tried to jump it this am it was to no avail. Took battery out and had it charged at parts store, reinstalled and still nothing..
I pushed start button twice without foot on brake;it just flashed some symbol quickly, nothing more.

I have a 2004 prius that had a HV batyery problem. HV battery was rebuilt. After that car started ran but after shut down it will not start. It will only show red triangle, abs, vcs, yellow tire. Basically all yellow lights on dash board except check engine. Also on the MFD it shows the red car with exclamation symbol. I scanned it but shows no DTC codes.

I had my dead 12V replaced two weeks ago with a new OEM batt. The car had been working fine until I parked it in the garage four days ago. There was a single bar of HV charge left at that time, at least according to the MFD. Today it's stone dead, not even a single beep or a blinking light. I've attached a working 12V battery to the jumpstart points under the bonnet and the dash came alive, but the car would not start. The HV battery gauge on the MFD had no bars, and the shifter indicators were all flashing.
Is my HV really dead? Would it really take only four days to discharge completely and take the new 12V with it? Perhaps the OEM 12V was faulty and another 12V battery (not a booster) is not enough to jumpstart the car?

I just replaced my 12V battery and now the car won't start. It will take a jump and show "ready" on the dash but as soon as the car is turned off, it won't start again - no lights, nothing. I checked some fuses and they looked fine.

I have an 06 Prius and I just swapped the transmission out. I got the car to start while it was still on jack stands but after I lowered the car onto the floor I went to start it and it would not start. I am wondering if my battery could be the issue. I am new to prius so I am not sure how this is supposed to work. When I initially put the service plug back in and started the car the display was showing about half bars. When the car would not start I am only showing one bar on the battery display...I assume this is showing me the HV battery charge. So I went into service mode to check the 12volt battery, while in acc the car shows 11.7Volts, then when I switched the headlights on it dropped down to 10.8 volts. Is the 12 volt battery bad and stopping the car from starting? Can I put my jump box on the 12 volt battery and try to start the car?

I changed a bad cell in my hybrid battery (only one cell was bad) and put everything back together and it wont start. I've double checked all connections, fuses, everything I took off. I put the orange plug back in, fiddled with it, pushed it in more. It's got a brand new 12V battery and I dropped it off at autozone to get it charged up as well. Here are some pics and what it's showing .....
