Prius (2010-12) :: Engine Making Pinging / Knocking Noise At Low Hybrid Battery Level

Recently I started to hear engine pinging/knocking-like noise when the hybrid battery level becomes low like two bars and the car starts a charge cycle. I also hear it occasionally when I accelerate on uphill. Is this normal or should I take it to a mechanic?

Prius (Gen 1) :: Input Vol Error Appears When Charging Battery

I was wondering how I would charge my gen 1 battery cells and balance them with my IMAX b6 lipro battery charger. Every time I try to charge it or hook it up the thing keeps saying "input vol error". Now I don't know if that means I need a different ac adapter since I'm now using a 19.5 v laptop charger and most of the time they use a 12v ac adapter.

Most of the cells have a reading under 6v but we have 38 new cells coming in today. How we can balance them with this charger because I know it has a balance charge setting for the lithium batteries. That has a separate plug though. Should we just put the cells closest to their voltages and have them balanced that way?

Prius (2010-12) :: Battery Charge Level - Never 100%

Seen the battery charge level at 100%? The battery charge display seems to never go up to the top bar. I think I may have noticed it once, but I might have been dreaming that.

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

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 (2004-09) :: Checking Water Level In Battery

After trying to check the water level in my auxiliary battery and not getting a clear view of any place to add water, I decided it was time to remove the battery so I could get a better understanding of how this was to be done. I went through the whole process of dismantling all the brackets, clamps and wires that were in the way, removed the battery and, to my surprise, read the warning on the top that said "Never add water" and "Do not attempt to remove cover". Oh well, I'm supposing this is an agm battery and I'm going to let "sleeping dogs lie".

I got prius i-tech Australia (should be IV or V in US). I just noticed this morning that my fuel economy is better when I got 6-7 bars on battery level, and worsen if i only got 2-4 bars. Is it just my imagination or any explanation for it?

Prius (2004-09) :: HV Battery Drop Discharge Level Running On ICE Only With Slow Acceleration

I have a 2005 with 165K on it. Just within the last 2 weeks, at start up, no matter what level the charge shows on the display, the HV battery will almost fully discharge and then come back up to full charge within a mile of driving. I just replaced the 12V battery thinking this could have been an issue, but it didn't change anything. The car never acted like this since I bought it in 05. When it drops to the discharge level, It running on ICE only, with the typical slower acceleration. What could be going on?

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 2) :: New Hybrid Battery Installed Now Car Will Not 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. (none of the books covered this.

Prius (Gen 3) :: Hybrid Battery Downs The Bar When Car Is Parked

I've had my 2015 Prius Two for almost 6 weeks now, and so far am loving it. However, I noticed something strange today. I'm pretty sure that when I parked at work this morning, the hybrid battery was nearly full (two bars shy of full, I think). When I came back to leave work (~6 hours later) and started the car, the hybrid battery was down to only two bars (as in two bars above empty mark).

Prius (Gen 2) :: Hybrid Battery Starts To Go Down Quickly When AC Is On

Since the summer started, our hybrid battery has been acting different - when the AC is on (even on low), the battery starts to go down quickly! It happens when we are not driving, but standing in traffic or parked. We just changed our 12V battery and I though it would work, but it didn't work much. In order for it to charge up, we have to keep driving. Is that normal? If not, what can be the problem? What can happen when the hybrid battery will loose charge?

Prius (2010-12) :: Hybrid Battery Fan Turns On Quite Often

It seems like the fan that cools the hybrid battery pack turns on quite often, almost everyday after two or three hours of driving. I heard it once or twice on my '05, but on this one I hear it pretty much everyday.

Prius V :: Hybrid Battery Lower When Starting

I've noticed often the hybrid battery level is lower when starting than when I shut the car off. My thinking is: maybe it was used for cooling either the battery itself or the engine. Is that correct and normal?

Prius (2004-09) :: 2007 - Hybrid Battery Always At One Bar Down?

My concern: The hybrid battery, or the monitor really, has never, ever, not once, shown an all-bars charge. It is almost always at one bar down, and will drop below that but never goes above. My brother has a Gen I and his battery shows all bars from time to time. Not mine.

Prius (2004-09) :: Hybrid Battery Is Low Overnight

My hybrid battery has been running low the past few days. This has never happened before, but it has been around 90 degrees out during the same few days. I noticed it this morning as I left for work. It was down to two bars when pulling out of the garage. I was getting pretty nervous, but at least the ICE was charging it. Although, it never fully charged the system, as I live pretty close to work. On the way home, I tried to drive around for a mile or so to see if I could get the battery fully charged.. The best I could do was four bars. Is this typical of the hybrid system in warm weather? Should I be worried about it? Also, the system has a fan, why doesn't it come on if the hybrid battery is so temp sensitive?
