Prius (2004-09) :: 2008 - CEL Came On / Battery Display Shows The Battery Is Green
Dec 23, 2013
I tried to turn on my car this morning, but the "Ready" sign didn't go on. The whole display is black. "Check Engine" sign blinked briefly. Battery display shows the battery is "green". Everything else works - cd/radio/bluetooth, etc. As I tried to start it, the screen showed that the engine briefly charged the Prius battery, then it was all quite. I tried to wait and restart a few times, but still the display was all black and no "ready" sign. I WAS able to still move the car, but I didn't chance to drive it out of the garage. I just had it serviced (oil/fluid change). Small battery was replaced in July.

When battery is low (purple bars IN DISPLAY) EV mode is not allowed, obviously; but WHY is it not allowed when the battery is full or nearly full (green bars on display) ?

I have noticed that my 2008 Prius does not always engage EV mode (after I push the EV button) when the battery is green (nearly fully charged) and speed is well below 45 km/hr. Message displayed is "switching to EV mode is invalid now". So it seems there are factors at play other than the speed and the level of traction battery charge.
What these are? Is battery temperature monitored? Will the operation of the air conditioner affect it? Most times it doesn't but I wonder if under certain circumstances it might.
I use it at times if I am going up a slow speed incline, often from a standing start, knowing that there will be plenty of opportunity to recharge shortly after.
Weather here is pretty warm- around 30C maximum during the day.

2006 Prius with 130k miles. I'm thinking that my HV battery has slowly deteriorated to the point where it's causing drivability issues, and now needs to be replaced.
The main symptoms I'm experiencing are rapid charge/discharge according to the MFD and significant loss of power once the battery has discharged to one bar. I realize the latter is "normal," but the problem is that I'm seeing one bar frequently now. Hill climbs that my car used to do with no problem and would drain the SOC to 2-3 bars now cause the battery to drain to 1 bar about half-way up and then loss of speed from 65 mph to 45 mph by the time I reach the top. Descending hills, it's not unusual to see the SOC go from 2 bars to 7-8 bars within 30 seconds or so.
I'm not seeing any error lights, and my (cheap) code reader does not report any logged DTCs.
This seems to be a slow degradation of battery performance, rather than an outright failure. I first noticed that the battery would charge/discharge a little quicker than it had been at about 90k miles. At 99k (before the warranty ended) I took it into the dealer and they tested the HV battery. Block voltages ranged from 16.59 to 16.68 V and resistances ranged from 0.025 to 0.026 ohms. Based on this, they said that the battery was fine, and sent me on my way. Since then, the problem has just gotten worse and worse, though.

I have a 2007 Prius and the red triangle showed up. It has less than 50,000 miles. I noticed that almost right after I start it up the hybrid battery fan kicks on. This leads me to believe that maybe one or more cells in the hybrid battery are overheating due to charging problems. Is there a way I can check this out without going to the dealer?

About to hit 130,000 in 20 miles. For the past 10-15k miles, I have been consistently getting under 40 MPG, about 36/37. Only can I get 40+ for a whole tank when I do mostly highway driving. Before, my tanks would average 42-48 mpg.
My battery is also doing some funky things, sometimes when I turn the car on for the first time on a new day, my battery will go from green or blue (the blue right before it hits green) and will literally drop to one or two slivers of red in 15 seconds. I took it in when it first started doing that and they did a software flash or update, something along those lines.

So our car has performed flawlessly since 2005/135K miles. Still getting 55 mpg in the display in the summer, 45 mpg in the winter. Only issue is traction battery SOC quickly goes to full green when coasting downhill, and 1 or 2 purple bars when climbing. In Colorado, this happens a lot. Within a mile or so coasting downhill the SOC is full green. Question is: should I replace the traction battery? Is there any harm to continuing to experience this behavior? When full green, I realize I am using friction braking over regen braking, have actually felt the crossover from regen to the pads, as the SOC goes full green.

I've got a 2010 Prius w/ NAV. Yesterday morning, my Prius would not start. When I pressed on the brake, the green "Ready" button would not light up. When I pressed the start button, the NAV screen came on as did some of the dash lights, but the car engine itself was not on. When I hit the start button again, I had a yellow triangle on the left side of my screen that continued to blink.
From reviewing the forum, I believe that the issue is the 12V aux battery. I was able to get my car into maintenance mode, and the 12V battery was reading 8.6V; however, this was after my car had sat in the garage for 10 or so hours. However, by going into maintenance mode, I was again able to get my car to start. This morning, I drove my car to work (about a 15-20 minute drive). After I got to the office, I turned the car off and got back into maintenance mode. This time, it was reading 11.6V on the battery.
Am I correct that this is most likely an issue w/ the 12V battery going bad on me? I purchased my Prius in July 2010, and I have never changed the battery. It sounds like the "typical" lifespan for the battery is right around 4 years, so this seems to make sense.

The 2007 Prius starts and runs fine with no problem. However, the 12v battery check with a multimeter shows 9.9v reading. Does this mean that the 12v Battery is coming to end of life and needs to be replaced.

My '06 only shows 1 blue bar when I start up. Is this a bad indication as to its' longevity? Got me a little worried......126K on the car.

As I'm driving along, the normal battery strength on the MFD shows 5/6 blue bars but occasionally, it will change to the last but one green bar and sometimes all the bars go green.
Everything else is fine, no warning lights etc.
Is this a normal?

I saw a really weird thing happen about half an hour ago. Hadn't driven that car today until I made a quick trip a bit ago to pick something up.
As I was coming back from the store I noticed the display was showing extremely low numbers with barely any speed/coasting. After I got up to ~30mph and started slowing down, I noticed the display was actually showing the mpg decrease as I applied the brake.

My 2008 recently had auxillary battery replaces. My display (seems to me) that the battery bars on the display seem to be low or go low much more often. At freeway speeds the battery appears to be charging, that is, the number of bars get more numerous.

I own a 2008 Prius with 87k on it. The factory hybrid warranty was good through 11/15 and on 1/22/16 the dash lit up along with the MFD screen. After research I thought it was an inverter pump. I got the call from Toyota that it was throwing a P80 code meaning it is the hybrid battery. The dealership told me that it would run 3200.00 for a new replacement. I called the service manager and had him send in a goodwill exception since we service our 7 other toyotas with them.
Toyota corporate responded they would cover the battery under goodwill but I would have to pay the labor cost of 450.00. I spoke to the service manger and the dealership is covering half of that which I'm only liable for 225.00. I'm not out 3200.00 but after doing more research the typical battery last 60-80k. Some are luckier to get over 150k. For those Prius owners approaching those miles beware that you might need a battery replacement. This will be the last hybrid I will ever own.

The battery went dead on my 2010 Prius and when I had AAA jump start the car the clock plus the display with odometer, mpg, hybrid battery graph etc, no longer light up. Everything else seems to work.
Is there any easy way reset it other than taking to the dealer? (Could a fuse have blown etc.?)

Prius battery charge display is not very meaningful. Those line bars are not telling me much.

I am currently driving my dad's 2008 Prius because of other vehicle problems. When my daughter got out of the car last night, she did not get the door closed all the way. It sat that way all night in a VERY cold garage. Now it will not start and the malfunction indicator lamp, which looks like a check engine light to me, is very faintly flashing. I figured the battery was discharged and attempted to jump it per the manual's instructions. It still will not start and the lamp is still flashing. I can hear clicking under the hood, as well.
Do I just need to leave it hooked up to the jump vehicle longer? OR, is this a "dealership necessary" issue? I would have to tow it to a dealership, since it cannot be started, which creates a whole new set of problems. ( The car is parked in my garage and would be very difficult to get it towed.) What I may be doing incorrectly?

I've watched the DVD, I've browsed through the manual and I still don't understand this car. After 2 weeks, I have 150 miles on the car and the battery display has never shown it to be more than half charged - mostly under half, like only highlighting/reading 3 bars. I'm averaging 28 mpg. I've driven in power mode and EV mode and neither seems to make a difference to the mpg. I've been on the Hwy with it, but due to construction zones haven't had it up past 60 mph. Most of the miles have been racked up on roads with speed limits of 35/40 mph. I guess what I'm asking, primarily, is should I be concerned about the battery not fully charging? And, is there a break-in period with this car like there was/is with American made autos?

I have had my '08 Prius for 3 years and have little to no problems with it. This morning I jumped in to go to work and the entire dash lit up and then faded out and died. The only lights still on is the check engine light, Airbag light and the little green light on the Park button. The worst part is now I can not completely shut it down. I am wondering if it is just a dead battery or if this is something bigger. If it is a dead battery I am baffled at how it could be. I have AAA coming to jump it and I hope that is all it is. Sound familiar?
