New knockoff battery pack worth it for my 2005 - 299.999 KM?

    I have a 2005 GenII with a little over 300.000 KM (200K miles) with a triangle of death, a P0A80 fault code, loss of power and cooling fan on in the back.

    Took it to a shop that specializes in hybrid replacement and they confirm one or more bad cells and I need replacement of the battery.

    Been here before 1.5 years ago and at the time replaced my battery for a "revised" one (they take good but used cells to create a "new" used battery) but it has only lasted me 1.5 years so doing that again is not really a viable option I think as the warranty is only 3 months which is a big risk (costs 500 euros).

    I have been looking at buying a 2010-2012 Prius with less mileage but they are quite expensive (~10.000 euros for > 100.000 kilometers) and I really love my current car. The GenIII does not really offer me anything I want over what I have now, except reliability as my current one is dead.

    The hybrid shop offered me a new battery instead of "revised". It is a Chinese knockoff and not Panasonic. It will cost me 1450 Euros and comes with a one year warranty although they claim to have never had any problems and have been selling them a lot for over 4 years.

    I read positive things on the knockoff batteries on this forum and am tempted to take the offer (I really kind of already did) and have it built in this Friday.

    Does anybody want to chime in? Is this a smart way to enjoy more years with the car I am happy with or am I taking a big risk and throwing away my money?

    What do you think?

    How much is an OEM battery from the dealer, with or without installation? o_O

    The only knockoff that might be worth the cost, is offered by one of our esteemed members : NewPriusBatteries

    If you do go with some other knockoff please take pictures of the battery before the install, and share future updates here.

    Edit : fixed link, seems like there are some server configuration issues that need sorting :eek:

    Not sure, I'd have to call the dealer but if I remember correctly from the last time it was roughly € 2500. I also have the option to purchase official Panasonic from the hybrid shop I visited, this costs € 1850.

    Care to elaborate? Does that mean that the other knockoffs often fail soon? Do you have any experience with this?

    Might check with the various available dealers once again.

    Didn't know you could purchase new prismatics over the counter (Panasonic or otherwise), are they new or ??

    Take some photos and post them for further advice.
    No personal experience with either, though the stories told are that the CEBAs (or their knockoffs) don't test at the claimed capacity.

    The battery linked above is reported to test above the OEM capacity, and shares the CEBA form factor. Your mileage may vary.

    Unless they buy the battery from a Toyota dealer, it would not be the same as the OEM pack. Panasonic only sells the modules direct to Toyota.

    The vast majority of members here have had bad experiences with the knockoffs which are usually just old packs with used modules replacing the failed ones.
    The kit from newpriusbatteries is a kit of new cells that basically gives you the equivalent of a new battery for much less cost. They are based in the US but I believe they have sold the kits elsewhere too. The link is in my signature or @2k1Toaster may respond here.

    @SFO @Prodigyplace thanks for your replies!

    I have contacted the shop and it is indeed a new CEBA that they will use as replacement. I searched the forum for CEBA and indeed found a big topic from 2K1Toaster detailing his quest designing his own battery based on the ceba formfactor.

    After reading this I would definitely prefer his battery however it is not available here in the Netherlands and as I need my car AND need someone else to install it, his battery is not really an option for me...

    The option I do have is to have the new CEBA installed Friday. From this forum I understand that it is not as powerful as the original from Toyota, but it is difficult for me to know how much less...

    In other words, is this battery likely to die within a few years? Will this battery make my car use a lot more gas than I am now?

    If not than I don't really see the issue. It is not as good but also not as expensive. Original at the dealer will cost me 1900 which I find too much on my 2005 car with over 300K kilometers.

    I wonder if the Prolong grid charger could revitalize these CEBA batteries?

    I would think not, at least not until a good way down the road.
    Again, I wouldn't expect so. If I recall correctly the tests on the CEBA units that 2k1Toaster did they came out with these packs rated at 3.5 Ah capacity. This against the OEM capacity of 6.5 Ah and gives a 53% discount when comparing the CEBA vs OEM. Assuming you can nicely factor that in a linear fashion, which I am prepared to accept is not necessarily so, it would mean you could expect that the battery might last only 5.3 years to 8 years rather than the 10-15 years you could expect from an OEM.

    I would also expect that maybe the battery would cycle more frequently given that it had 53% less capacity. But you live in the Netherlands, which being so flat is hybrid paradise, so you will more likely be very gentle on the pack which will help it a lot.

    My €0.02.

    Alle beste, meneer.

    PS, I'd expect the price of these to be 53% of the cost of a new OEM so €980.

    I don't see why not.

    Bedankt @dolj

    If I can get 5 more years (~125K KM) out of this car with the CEBO battery I would be more than happy to pay the 1500. Indeed no mountains here, mild climate and I am gentle on the battery with my driving style.

    450 additional euros is significant, but then you would have an OEM battery that would last, with an increased resale value.

    Will the knockoff shop let you keep the old modules and sell them off?

    When was the last time the HV battery fan was cleaned?

    I guess that's true, but we are talking about resale value on a 2005 car with an odo meter stuck at 299.999 so I am not sure that would be worth investing an additional 500.

    I didn't ask but am sure they will not let me keep them as they will definitely be using them to create a new reconditioned set to sell to someone else...

    I have no idea, never by me in the 3 years that I have owned it. Perhaps when I had the battery switched for a reconditioned set 1.5 years ago? Not sure...

    @2k1Toaster tests of CEBA cells showed they do not produce the rated capacity. He helped them design the brackets holding the cells, but his cells are higher quality. Have you verified he cannot get a kit to you in the Netherlands?

    I did not verify this with him yet. It would mean longer wait during which I don't have my car and depending on weather he knows the kit from 2k1Toaster it could also present difficulties for them concerning the warranty as they normally work with CEBO and have spare parts/cells for that probably. But of course I can always ask.
