Replying to: evelyn6 (Apr 10, 2009 6:09 pm) You sound like you are getting P1447 errors. The car will continue to try to use the battery, but will have less and less success. You should only see a loss of assist and a reduction in fuel economy because the car will constantly try to charge the battery. You are already seeing the loss of economy. EVENTUALLY (like probably months from now) the car will give up on the battery. If it does because of a battery degraded condition P1447 then it will simply have no assist and no regen for the brakes. If it gives up because the battery has started to overheat (P1449) from the charging, then the DC-DC converter will shut down and the car will stop charging the underhood battery. Then you MUST fix it. You'll see the alternator light (or whatever it is called) at that time. >2) Can nightly charging my (relatively-new) 12V battery help keep my hybrid battery charged? If the hybrid battery sucks power from 12V while parked, could this extend my hybrid battery life, long enough to shop for a new ride? No. The 12V battery has nothing to do with the 144V hybrid battery. Also, when parked, relays disconnect the hybrid battery from the system. It does not ever consume any power from the 12V battery. >3) I had both catalytic converters replaced around 10k on recall and again at 98k; if they're likely to fail again soon, why replace hybrid battery? Any insight? no pun intended Why would you assume they would go bad again? I replaced mine at 96K. It was clogged. Normal failure. (You always replace both because if one is clogged, the other probably is too.) >4) If I drive another vehicle while advertising this car for sale, is the hybrid battery going to die from being parked too long? Drive it at least 30 minutes per week. >Honda America won't budge on the $3000 price tag, though I was told less than half that cost when I bought the car. Reluctant to invest in this car, trying to decide whether to keep or sell You can repair the battery to like-new (or at least "spring-chicken") condition for 1/4 to 1/3 of that. Search google for "ima battery repair honda" and check the first listing. |

| I have a 2002 Honda Civic with 125,000 miles. My battery will only charge to about 80%. If the car is not runnin gofr 2 hours and then driven the battery will charge all the way? Any ideas? | |

For at least 6 months, I have not seen the IMA battery fully charged on my 2008 Civic Hybrid. During this time, I have also noticed a reduction in my gas mileage. I haven't gotten more than 36 mpg in the past 10 months. I would imagine this is due to the constant charging of the IMA battery, without every reaching capacity. So, why did I spend the extra $$$ on a hybrid when I could have gotten this mileage with the standard model. Twice in the past year, Honda has "checked my battery and charging system and all was fine". This week, I took the car in on Tuesday for a 3rd time after having a lengthy discussion with the Service Manager himself. My car would be worked on by the "shop foreman who is the Hybrid expert". I made it clear that I see the battery charging as I'm driving, but the last of the 8 bar never illuminates and after sitting for several days, I find only the last 4 bars illuminated. This occurs in the parking lot at work after the car is parked for 8 hours, too. My conversation with the person scheduling the appointment was ... they either need to fix the problem or help me get out of this car without losing my ASS. This is ridiculous. I receive a call from the "Expert" telling me the car needed 4 software upgrades and these would correct the issue. Their "testing equipment" which downloads/uploads these updates wasn't working properly, so Honda sent another which would arrive in 2 days. I was without a car for 2 days since they had shuttled me home. On Thursday morning, just after 9 am, I received a call that the car was finished. When I picked it up, there were 4 bars on the IMA battery. I drove the car 40 miles to charge the battery. Despite the fact that I tried to ensure minimal use of assist and maximum charging, the battery FINAL reached a point of 7 bars, but by the time I reached my driveway was back to 4 because of a MINOR INCLINE. I'm not an expert, but it appears the IMA battery is TRYING to charge, but if it can't charge to the maximum and HOLD the charge, IT ISN'T WORKING PROPERLY. I expected them to replace the batteries earlier this week. Has anyone here experienced similar charging issues? Enlighten me... I'm currently logging IMA battery performance for 10 days, taking pics of the levels, the charging/assist, etc and putting together an obnoxious technical review of the situation. Perhaps I need to have a MAN explain it to them. Is the problem that a WOMAN thinks she knows what is going on?

Replying to: funtechie (Jul 31, 2009 7:30 pm) 1. For at least 3-4 months I have noticed reaching the the last bar on the IMA to be very difficult. I need to accelerate real carefully to minimize motor assist. I have counted only 6 - 9 times reaching the 8th bar in this time span and reaching the last bar seems to take forever. 2. When I spoke to the dealer they "talked in code" and wanted $90 to check the charging system/battery. I decline. I figure the codes would not show a problem at this point and I wanted more "ammunition" when I speak to the dealer again. 3. I also notice unusual charging behaviors while driving (long steady trips - Not City). If the IMA fell into the 4th bar it would try to charge, as it should, but sometimes the charging would continue until I reached the 7th or 8th bar. It almost seem that the car knew its battery was low and, if I gave it he opportunity on a steady run, decided to charge all the way. 4. As far as MPG. When my wife drives the car she never gets above 35 mpg. Because of my "hyper-miling" techniques I can still get 55-60 on long runs and 45 - 50 around town. As I said, I drive the car like a science experiment and have learned how to squeak out more mpgs. It was on my trips to work during the spring that I first noticed the decline in IMA battery life. I will continue to monitor and take data. I will post these results shortly. |

| When I bought my 2006 Hybrid, the salesman told me how the 2006 had been changed from previous models. One change was that the charging system did not have as its goal a 100% battery charge. The goal was to average a 75% charge. It seemed that trying to maintain 100% was too taxing on the system. Under normal circumstances expect the charging meter to vary between 50 and 100%. | |

I understand the goal is not to have the IMA battery at max charge 100% of the time, however, my fuel consumption is 30 to 35 (sometimes less) while the battery is at 6 bars or less. My colleague has an identical 2008 HCH and continues to get the 50 mpg that I got with this car during the first 6 months. The driver, the drive to work and the car have been consistent. What has changed is the IMA charge level and the fuel consumption. A week ago, with 7 bars on the IMA battery, I drove 30 miles at 45 to 55 mph and saw 57.9 MPG. As soon as I got onto the highway, I found the battery dropped and my MPG dropped considerably. After 70 miles, I was at 35 mpg. THAT IS A PROBLEM. I purchased the car for the fuel efficiency. I could get 35 mpg with the standard Civic, so why would I pay a premium for THIS PERFORMANCE? I have purchased a second car while I address these issues. 3 days ago, I took the HCH to Roberts Honda in Downingtown. In a short test drive, there doesn't appear to be an issue. HOWEVER, the performance of the battery is erratic in the longterm. I've asked the mechanic to drive the car as he would his own for at least 3 days. I really want some to explain why I've lost 30% of my fuel consumption at the same time the battery indicator began to show reduced levels if the charging and battery systems are functioning properly. If I don't receive satisfaction, I'll be pursuing action through the attorney general's office. I first noticed the fuel consumption dropping 10 months ago, but it was still in the 40s. I was told it must be my driving, but it doesn't seem to matter if I drive aggressively or using hypermiling techniques. The result is the same. THIS IS UNACCEPTABLE. On one occasion, I left my driveway at 7 bars, saw 4 bars only 2 miles later (downhill) and less than 10 miles after that was at 2 bars. I doubt the level should ever indicate these values unless travelling in a mountainous area. This was essentially a flat terrain and when accelarating I focus on less than 3 bars on Assist.

Replying to: funtechie (Aug 28, 2009 9:39 am) BUT- i too have seen my mileage go down into the 30s and 40s. it makes me really angry. my friend who owns a Cobalt gets the same gas mileage as me!!!! it's absolutely ridiculous! when i bought the car it got in the 50s. Funtechie- PLEASE, post here if/when you take action! i would like details on how to do that. i feel like there's nothing else i can do and honda always jerks me around. i get email reminders when people put a new post up, so your reply will go to my inbox, that would be great help! thanks!!!! |

I have a 2005 Civic Hybrid that the dealer is telling me needs a new Hybris battery pack. I have found several places on line that speak of reconditioning a toyota, but nothing on the Civic. Does anyone have a link to information or could provide me with information as to options, if any to the new $3000 battery pack?
