Prius (Gen 2) :: Battery Level Never Fills Up - No Bars Showed Up


Jun 3, 2011

I notice on my MFD that my battery level never fills up to the top. I've seen purple when it's low, blue, and green when it's in a high charge state, but there's always a missing 'never filled in' space for another bar, though always blank.

I can let off the gas downhill with it already green and that blank space for an extra green bar never fills. It just stays blank. Is this normal?

Prius (Gen 2) :: Battery Fills Up And Engine Brake Kicks In

My daily route includes the following road segment,

5 km steep climb (30 mph, 50 kph)

3 km fast downhill (60 mph, 100 kph)

4 km fast climb (45 mph, 70 kph)

6 km steep downhill (40 mph, 65 kph)

The speed between parentheses is the traffic flow speed for each segment.

Even though I tried varying the driving speeds and styles, a constant problem I have is , Before starting the final descent, my battery is almost full. Half way down the hill the battery fills up and the engine brake kicks in, which means energy is wasted.

1. Will the battery be affected in time by the fact that it fills up to 80% repeatedly?

2. If I drain the battery on the last climb by slowing down and switching to electric and then fully recharge it on the descent (and avoid engine braking), will this reduce the battery's life span?

Prius (Gen 3) :: Hybrid Battery Sometimes Goes Down To Two Bars?

I'm a new Prius owner and don't know if this is normal. Sometimes after being parked for a while and restarted, the icon shows the battery is down to 2 bars. It charges back up after a mile or so of driving. Also if I sit and idle for a while, the battery will drop down, and once going thru a car wash (car in Neutral), a message came on the screen that the Tractor Battery was in trouble (I don't remember the exact words). When I put the car in gear and drove off, the message disappeared and the battery charged up. What's the deal?

Prius (Gen 3) :: Only 2 Or 3 Bars On The Battery In Stop And Go Traffic

I have been driving my new 2011 prius for a week now and have noticed that in stop and go traffic I occasionally get down to three bars before the engine kicks in. Is this normal?

Also today I was in a traffic jam for a half hour and got to 2 bars a few times(lots of stop and go). Is this normal also? When driving on the freeway the bars are always 6-8. There are no colors on the bars, just white.

Prius (2004-09) :: HV Battery Dropped At 2 Bars

So I met my wife after work. I was killing some time with my son. We drove across the street, then to a neighboring shopping center. I changed the display to see the more accurate instant MPG and noticed my battery was at 2 bars. This is the first time that's happened, that I'm aware of. During normal operation, it stays at 2 bars above the halfway mark, or above.

Prius (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) :: Low Bars On Battery Gauge After Idling A While

I am a relatively new 1st time Prius Owner. I have a 2007 Touring Model, [69k miles] that I love so far, and have only had it about 3 months. I do Night Watchman work part time as a retiree, and mostly sit around equipment yards in my Prius. I've noticed that although everything seems fine on the road with no problems or unusual occurrances, that when I do start my Prius and let it idle, the Battery Bar Gauge will after about 5 minutes or so, begin to drop, until there are only 2 bars left, which causes me to panic and start driving around to get the battery bars to start coming up again. If the bars go to 2 or lower , [1] and I don't do anything, will the Pius go dead on me, or will it eventualy kick the gas engine in to start charging the battery and make the number of bars go up? I don't want to get stranded in the middle of nowhere, and when I do idle, it's just to throw on a little heat, or have the radio on, no lights .

Prius (2010-12) :: Battery Charge Down To 4 Bars Overnight

Should I be concerned..I have been noticing my battery is charging down overnight. I checked and all lights are off. It does charge immediately in the 10 mile I drive to work..but I am concerned why overnight it should be discharging.

Another Question - The right/left indicator sound is very muted..is that normal? Like, if I have the indicator on to merge into traffic, I am not sure it is as I can barely hear it chirping..

Prius (2004-09) :: Sitting Idle For Three Days - Battery Down To Two Bars?

I had my 2005 Prius sitting idle for three days and when I last used the car it had 6 bars of battery (blue). Today I turn it on and it has only 2 bars of battery (purple) and the engine stayed on about 10 minutes to charge the battery. After about 10 minutes it went all the way to 7 bars (green) and the engine did its normal idle stop. Is it normal for the battery to drain that much in only a few days?

Prius (Gen 3) :: Battery Indicates 2 Bars And Engine Falls Back To Ignition On Mode

I have a 2011 Gen3. It's driving perfectly. Its charging when being driven by the ICE as normal. Its also charging by regen braking. However, when the car is 'stationary' with full EV battery- and when it looses its charge with lights, fans etc, it cuts out. When the battery indicator drops to the normal 2 bars, the engine falls back to 'ignition on' mode (i.e the dash lights illuminate and the steering goes heavy)

Prius (2004-09) :: Traction Battery Go From 7 Blue To 2 Pink Bars Within 5 To 7 Minutes

2004 Car has 106,800 miles and for the last several weeks, when I'm stuck in traffic, like trying to get into the Lincoln or Holland Tunnel, the battery seems to go from 7 blue bars to two pink bars within five to seven minutes. Used to be that it took 3 five-minute bars of traffic, running fully electric at 100 mpg, to then go down to 2 pink, when the ICE would run and charge the battery. Today the battery indicators went down to 2 pink after sitting in traffic with the AC on and stayed there for the remainder of the time we sat in traffic - another 45 minutes or so.

The ICE would run at idle sometimes, but didn't seem to bring the battery back up unless we were really moving. A couple of times I held the brake with my left foot, revved the engine with my right, and that seemed to bring the battery up a couple bars. After we finally got going on the highway, the battery recovered. I got no warning lights, no triangles. But I'm wondering if these are symptoms of the battery failing. Time to get it tested at the dealership?

Prius (2010-12) :: Power Bars Rapidly Disappearing - Battery Drain

I recently was stuck in a traffic jam in the middle of the Mojave desert. Outside temp was about 102 and we crept along for maybe 15 minutes going no more than 5-10 mph. I had the air conditioning on. I noticed the power bars were rapidly disappearing and got worried that I would lose the battery if I didn't get moving. Needless to say, I finally was able to speed up and the bars came back. (dropped to 2 bars).

Prius (Gen 3) :: Parked With 6 Bars But Power Up With 2 Bars

Had a Gen 2 years ago, first time with a Gen 3. Specs: 2011 Prius Two, not II, CPO'd with 83k miles. I've been experiencing this phenomenon for the past couple of days. I would park the car with 6 or 7 bars, but after 8-10 hours of parking it would power up with only 2 bars, or it would power up with 4-5 bars and quickly go down to 2 cars before it charges back up to 6-7 bars. I called the dealer and the SA tells me it's normal. I know for a fact my Gen 2 didn't and my TCH didn't. So is this something I should be concerned about or is this normal for the Gen 3?
