Battery Replacement

Well, today I got the news. Got the code poa7f, and my hybrid battery is at 19% capacity. I’m looking to replace it, and was quoted 2700 through Honda. Is this a fair price? And is there any way insurance would potentially cover a portion of costs? Any help would be appreciated.

First advice is build yourself a simple cheap <$30 charger/cycler and cycle the IMA pack.
Then reset the IMA useable capacity using a borrowed HDS or OBDIIC&C and see how long it lasts.
It's probably just got lazy and weak.

See this thread for details..

A company called Bumblebee Batteries makes hybrid batteries for the CR-Z, so you could have a look at their website: Find My Battery - Bumblebee Batteries

By the way, did you get this error out of the blue or did you notice something before (or maybe know that you or the previous owner did not use it correctly, for example not driving for many months)? I am very curious how this could have happened, since you are probably the first person on this forum to replace the hybrid battery.

I will look into those batteries thanks. It’s been a pending issue, I noticed a slow decrease in mpg at first, but it was hard to diagnose how drastic with a change to my wheel/tire/intake set up, then it became more noticeable and the battery would frequently and rapidly charge and discharge on even short trips. The last week, it was making the car pretty undrivable with the lack of torque when I needed it. I intend to keep the car for a long time so I am going to replace the battery. As far as when the code popped up, I would say that was maybe two months ago and reaching out to some people it seemed like it may have just been a software issue, which I know Honda issued an update for. On my own personal faults, I dismissed it as that but started to suspect something else. I am curious to know if replacing the battery is something I can do myself or not.

There is also a warranty on the battery that varies in length depending on where you live but it may take some convincing at the dealer to apply it. Even though it is expired you may be able to as a courtesy get the dealer to help. Since it is a 2011, was the update done to yours? If not it might help. Another option is a used battery and here is a source https://www.redlineautoparts.com/honda-cr-z/

Yours will be the first case of a replacement IMA battery in a CR-Z.:( But as they get older this will occur more and more.

In the Netherlands, there are a few companies that repair/refurbish hybrid battery packs to at least 80% of the original capacity. The cost of a refurbished hybrid battery (including installation and a 6 month warranty) is about €700, which is about $850. Even some official Toyota dealerships use their services, since Toyota offers a lot of hybrids in the Netherlands and hybrids sell really well here (tax/financial reasons).

Maybe you can find something similar in the US... I hope you will find a good solution! :)

I also drive a 2011 and mine has 170k on it. The battery still sees to be working fine. I have been wanting to build the charger that PeterPerkins was mentioning to see if I could coax a little more capacity out of my battery. This charge he has mentioned would likely cost less than $20 and should be worth a try.

Based on some things others have said, be sure to check your 12volt under-hood battery as well before you write your IMA pack off. The 12v battery is used to drive various parts of the management system, and you can get some strange things going on when circuitry is run under-voltage. (I got an IMA error when my 12v battery was dead, but at that point, it was too dead to even make the IMA motor start the car.)

That is not likely to be the problem, but a $100-$200 battery is much better than a $1000+ battery, if it is the problem!



I also drive a 2011, with nearly 170k miles as well. During a recent oil change, I had the dealership run a battery level test, and they reported that the battery still had ~75% capacity. I do a fair amount of highway driving though. I wonder if Cwilliamsvalenzuela lives in a large city or ends up doing some other kind of driving that resulted in significantly more charge/discharge cycles. Or, if it is just an early failure of multiple cells/packs.

@TNThomas @PeterPerkins hey guys, thanks for the links!
No, I didn't do anything yet because don't have the CR-Z, I was walking yesterday and spotted one in the suburbs and have spoken to the owner.
He might be selling his Honda so I decided to Google what it would cost me and so on :)
BTW is there a list of what is a must to check in a 10-year-old CR-Z before buying?

Yes i know but all engineers here in greece and i also ask 2 shops that do that job repairs hybrid batteries both telling me that rejuvenation is waist of money that the battery wont last up to 3 to 6 months they keep telling me to add a new one that I discover after a visiting them that they change the battery cells with new ones and keep the rest i dont know what to do cause i believe as u told me to and after research from internet rejuvenation will work anyway the situation here i leave is this are 3 shop that making that job and all of them try to install me a new battery and i can’t trust to tell them to balanced my battery when they all telling me that rejuvenation dont do anything and i spend money for nothing
 
#27 ·
Of course there is a chance the rejuvenation process won't help in your case.
We can only work on the information you give us.
Every battery is different.

But cycling is cheap to do <$50 and if it only last six months you could do it again.
Yes you risk a small amount to potentially save a lot more.

Of course you can buy a new battery if you wish.

O dont know wh they charge too much hear i read u said 60 bucks i just talk with a hybrid battery shop they told me 600 to do that i am thinking how i can do that by my self the problem i am leaving in a flat have no garage the car is parked outside on the road i have no access to electricity i must find a way very confusing here in greece all professional telling for rebuild my battery with new cells asking me 2.400 for that

Okay, so I looked more into the replacement options. There are companies out there that sell refurbished or new hybrid battery packs, that they can potentially install for you if your car is located within their service areas.

So far I found:

Unfortunately it appears they only carry hybrid batteries for 2010 to 2012 model years.

My questions are:

  • Has anyone used them to replace (including mobile installation) their failing or failed hybrid batteries?
  • Are there any options for 2013-2016 model years?

Interesting update, this morning I learned (per bumblebee website) that Bumblebee has merged with Green Bean Battery. Hopefully that provides an better alternative to stealership pricing to replace these batteries for the 2013-2016 model years

@CRZen-it By posting all over the place in different threads I can't work out what you are doing.

Keep everything in one place so we can help you.

So to recap.....

What is wrong with your current pack? We need exact details.
What fault codes do you have? These are vital.
Can you get an HDS IMA data list printout? This is highly desirable to help fix it.

Have your read the threads that were linked earlier?

You can't replace a Lithium pack with a Nimh pack unless you want to deal with the IMA code issue that will result.
See that previously linked thread for details.

We could possibly help you fix your lithium pack if we knew what is wrong with it.. See my questions above.

Unfortunately, I don’t think this has the information you requested but I do see some codes that have been mentioned in other threads. I will dive into it more when i can get to a computer.

@CRZen-it Yep you have a P0B3B fault which is a fairly common BMS board failure.
You need a proper diagnostic report and HDS IMA data list printout so we can identify which board is faulty.

You should strongly consider getting your own HDS Clone diagnostic tool to assist in this repair.
Then I can send you a replacement BMS board in due course or you can source one locally.

Read all that has been written on here about the fault code 'P0B3B'. Just search that phrase.

Make sure your 12v battery is perfect and well charged.

Post further information on the main P0B3B thread. (Read it thoroughly first)
