Prius (2004-09) :: Losing Traction Battery Charge In Morning
I have a 2005 Prius with about 170,000 km on it. I bought it two years ago used at 150,000 km. Everything worked fine for about 8 months, them I noticed the main battery started to drain on first start in the morning after driving a short distance. It would drop down to about 2-3 bars most days, especially on cold mornings. After reading on this forum for a bit I turned off the key locator, and it went back to normal for about 6 months, at which point it started dropping again. I haven't had any warning lights come on yet.
I replaced the 12 V battery, as recommended here with an Optima Yellow Top, even though the original one showed no voltage drop. It actually tested higher than the new Yellow Top I got. My fear is that the traction battery is losing modules. I'm planning on testing them soon.
Prius V :: Battery Losing Charge Whilst Driving
I've bought a used prius v ,the mileage is now 72k and as of monday (2 days ago) the maintenance reqd light came on intermittently when I start the car. So, I checked and saw that this meant it was due for a service, no big deal.
I don't know if it's linked but Monday I drove about 360 miles and then last night (Tuesday) I noticed my battery drained quickly on a 7 mile trip , it went down to 2 bars (they became blue on the car display) and took forever to go back up. Then same thing this afternoon but funnily enough, not this morning.
Prius (2004-09) :: ICE Rough Idle / Dies - Battery Won't Charge?
In reading a lot of the threads here, it seems that my traction battery or inverter is dying/dead? 2004, 135,000 miles.
A couple months ago, got the triangle of death and parked it at my office. Next day, came back and it drove fine. Then, a couple weeks ago, drove 100 miles fine, parked at the house. An hour later I hopped in the car and didn't get more than two miles down the road before it died. Came back a couple days later and it drives/runs fine, battery at 50%+ on the MFD. Had it towed to shop and they haven't had time to look at it, so I'm going to figure it out myself. I don't have a scanner but want to get one.
As described in the thread title, the ICE won't even run, and the traction battery drains down to one bar. If I let the car sit for a day or two, it will probably run, but I know there's something that needs to be addressed. Is it the traction battery, or possibly the inverter?
I called the dealer to do the inverter coolant pump recall, but they said I did it back in 2011. Was the problem identified back then? Or are they lying to me?
Geo - Metro :: Battery Is Losing Charge?
New battery, new terminals but my car won't turn over if I need to make a quick stop somewhere. I must wait at least an hour for the proper amount of voltage to build up and then the car starts just fine. What is going on?

Is there a way to keep the 12 volt battery charged, especially during extended period of time the vehicle has to stand idle (with accessory on).
I wanted to try firmly depressing the brake then press down the accelerator. This way the car won't move but energy is being used from gas and traction battery to recharge the battery?
Would like to know is this an okay method to maintain the 12 volt battery charged.
Prius (2004-09) :: Possible To Charge Hybrid Battery When Car Is Idling
I recently purchased a used 2007 prius. The car has not been driven for some time. I won it in an auction from a used/wreaked car lot and am in the process of fixing it up. I need to know if it is possible to charge the hybrid battery when the car is idling or will this only discharge the hybrid battery and if so, is there any way to charge the hybrid battery other than driving the car?

Prius (2004-09) Fuel :: Any Way To Force ICE To Charge HV Battery?
I got my car about 2 month ago, and i started to understand how she is working ( how the hybrid cars works in general ), in my daily trip, there is about 5 mile flat road, sometimes when I reach this road SOC shows 3 bars only and its not enough for EV that 5 miles road, but if the battery have more than 6 bars i think it will do the job, and if you will ask me why you don't charge it through the car movement, the answer is very simple, because I am gilding the car before getting that flat road, so, is there any why to force the ICE charging the HV battery?

My 2006 Prius battery is not holding a charge very well. About a month ago I had rodents in the engine and had both my stereo and wiring harness replaced at the dealer. I've noticed that every morning the Energy Monitor screen shows only 2 purple cells left in the battery. It always recharges as I'm driving it, but then it loses its charge after siting still a few moments. No idiot lights are on. I've done the DIY system check mode and everything says OK, except audio- it shows "check" in red. Also, my 12v battery is at 11.9. (I replaced my original 12v battery several months ago with no problems).
View 1 RepliesPrius (2004-09) :: Battery Charge Up To 8 Bars All The Time
My 05' with 130,000 miles has been acting weird lately. It likes to charge up to 8 bars all the time now. Before it was always around 5-7 bars. It goes down to purple 2 bars on a 2 mile hill climb. I see the bar from 6 going down to 3 or 2 immediately.
When I am driving on a flat road at constant speed. The battery is charging or being used continuously. Never does it stay at discharge or charge for longer than 2 seconds. The arrow goes green then orange then green, on and on and on. Besides that, it seem to drive ok. No dash lights what so ever.
Prius (2004-09) :: Battery Will Not Charge In Neutral Warning When Put It Into Drive
I've had my 2006 Prius since Jan. Today it started giving me a warning when I put it into drive. The warning was the battery couldn't charge while it was in neutral. It told me to place it in park. I did. I repeatedly tried and even drove out of my parking but it continued to say this with the ! in the triangle appearing. I've never even put it in neutral before.
View 4 RepliesPrius (2004-09) :: Engine Charge For HV Battery Not Working Properly
When stuck in traffic jams, and my 2004 Prius shows 2 bars on the HV battery charge, it attempts to start the engine to maintain the charge on the HV battery. What was happening was the engine would attempt to start and then it would immediately die. It would keep repeating this process, over and over again, and would not charge the HV battery. Once I started driving out of the traffic jam, the engine ran fine and it charged up the HV battery while I was moving down the road. I decided to clean the throttle body. My charging problem did change due to me cleaning the throttle body. Instead of starting and immediately dying, over and over again, the engine no longer dies.
It now revs up, and slows back down to idle over and over again when sitting still with 2 bars of charge. The display does not show any charging going on during this revving up and slowing down episode. I need some more hints as to what to check out. I am studying electrical diagrams of the vehicle, but I need a synopsis of which system starts the engine for HV charging, and which system keeps the engine revving at the same RPMs during charging while not in motion. The throttle body cleaning made my 257 K mile Prius run like a scared deer again. I just need to get her charging while sitting still again. 12 volt charging system is in the 14+ volt range and 12 volt battery with no load is around 12.2 volts.
Prius (2004-09) :: Shut Off While Driving - Battery Charge Drops Suddenly
Its not my car (its my father in laws). The other day his 05 prius (170k miles) shut off while he was driving. He pushed it home and I sent him a link on how to check the 12v battery. He said it showed it was low so he used his golf cart battery to go and take it for a test drive to see if that fixed the problem. In the drive way at idle his hybrid battery charge went up half way but when he went to drive it he got 1/8th of a mile down the road and it dropped to 0 then the car shut off again. He said the display says something about the battery (I haven't been over to look at the car).
They are sure its the hybrid battery, but if it was me I'd go to the dealer and find out for sure. My husbands aunt had her hybrid battery go out and hers did other things, like go into turtle mode and a/c blew hot. I think her inverter pump went out and she kept driving it till the battery got messed up, but anyway...What does my father in laws symptoms sound like? Is there any extra at home testing that can be done?
Prius (2004-09) :: Traction Battery - State Of Charge Drops To Red In 20 Minutes
A month ago I bought a 2007 Prius with 140,000 km. I notice that the state of charge drops into the 'red' bars within about 20 minutes of the car switched on, in Park with no accessories running. A mechanic connected his diagnostic computer and saw 2 cells are low. However, the mechanic informs me there is no value in replacing those cells as others are likely to go down, thereafter. Is there anything I can do to avoid having to replace the entire traction battery?
View 10 RepliesPrius (2004-09) :: 12V Battery Won't Hold Charge - Fusible Link Broken
About 4 months I accidentally reversed the polarity when jumping my car and fried my 12V battery and blew the fusible link. I replaced it with an Optima yellow top but due to other issues I haven't driven the car since about that time.
Last week I got most of the other issues resolved and tried starting the car, nothing. It was reading less than a volt on the voltmeter. I used my portable jump starter and got the car started. I only drove it to the gas station (1 mile round trip) to fill my tires and back. I went to start it the next day and nothing again. I thought maybe I didn't charge the battery enough since I hadn't been driving it.
I charged it overnight using a wall charger and again the next day it wouldn't start. Yesterday I jumped it again and drove it about 20 minutes, about half at low speeds (<30 MPH) and half at higher speeds. I got home put the car in park, but still on, and checked the voltage again, about 13.8 V. Turned the car off and checked again and I could see the voltage dropping like a rock. Within about 30 seconds it was down to 6V and within another 30 seconds it was so low that I didn't have any interior lights or dash lights.
It seems to me like the battery is bad. However after I "fried" the original battery I had similar issues. In fact the reason I had to jump it in the first place is because the battery died a few times in the same day. Could something be killing the battery?
Prius (2004-09) :: Keeping Engine Running To Full Charge Battery
I have posted separately about my 'supposed' dead HV dead battery. The charge was down to one bar and the the system didn't allow ICE to start for recharge. I finally got a reading of a about 207 volts today and when I fiddled with the start button on and off a few time today, the ICE started. After about 15 sec.
It indicated it was pumping juice into the battery. When it finally got up to about 4 bars it turned off. I had to move the car off the tow dolly (it's home for the past week) and did so in electric mode even though there was a Ready on the display the engine never came on. Before maneuvering it around much I tried to get the ICE to start again to recharge the battery, now down to 2 bars.
By pressing the gas in park and neutral, it would start and rev up but never generated any power to the battery. Fiddled around with the power button some on/off/on, etc. until I got the ready light and sometimes it would start charging but only once did it charge to 6 bars and usually stopped as soon as there were 4 bars.
Prius (2004-09) :: 2006 - Check Engine And Red Triangle / HV Battery Charge Fault
My daughter recently bought a 2006 Prius with 170K, Car was running great at purchase time with no issues but unfortunately the honeymoon was short lived. Less than 50 miles, she got the check engine light and red triangle. Car seems to still to drive fine. Had a dealer near Knoxville TN pull the codes and the only code was a P0A9C - Hybrid Battery Temperature (Sensor A) Range / Performance. Was informed also as they checked history on the car that another dealer had recommended a new hybrid battery and inverter. Dropped by the other dealer today to get the codes that they had seen. The codes they had pulled at 169K on the vehicle were:
P0A80 - HV Battery Cell Delta State of Charge Fault.
P3016 - either a bad cell, or a shorted cell in the hybrid battery
P0A08 - dc/dc converter status circuit.
Prius (2004-09) :: 2002 Toyota Keeps Dying With 3191 Code After 12V Battery Charge
My 2002 Toyota Prius keeps dying (triangle of death and OBD Code 3191) after running smoothly for a few seconds each time I start the engine. Clearing the DTC code allows restart. But the check engine light and triangle of death keep returning after a few seconds.
It has been doing all this since I recharged the 12V battery (which had been drained completely by a dome light left on for 3 days). Initial attempts to recharge the 12V battery were causing current spikes at charger, and (relay?) clicking sound under the hood. So I disconnected positive battery cable and charged the battery in isolation, then reconnected it to the vehicle after charging was complete.
When I reconnected the recharged 12V battery the vehicle (honking horn) alarm went off. But that stopped when I unlocked door with key. It may not be related, but I'm also hearing a fan-like sound (under driver seat) when ignition key is in run position. I don't recall hearing that sound in the past.
