    What about rebuilding before you get the P0A80 code? Deep cycling all modules to get capacity up and replacing modules that are not responding. Then rebalance the entire pack

    Thank you for yet another twisted opinion out of your library of thousands of them. :eek:

    What does the science say about the chemical composition of the reactive materials changing over time and irreversibly changing the capacity of the cell ??
    You seem to have conveniently overlooked that part.

    That is a temporary "fix" at best.
    Really it IS.

    seems like you guys in the US have the same problem as us, even though we are just a few years into the hybrid game, difference of opinion, can anyone say how long a module that was cycled multiple times to increase capacity, would maintain those new numbers voltage and capacity, 6months, 1 year, 2 years?

    The error codes are designed to tell you what to fix, not to tell you what to give up on. As for "memory" effect, I already explained that it can easily be restored and has been a standard practice for more than 3 decades when it comes to Nickel-based batteries. Just because Toyota doesn't use the standard battery care science for NiMH because they're greedy doesn't mean you have to go along with it: BU-807: How to Restore Nickel-based Batteries – Battery University

    And it doesn't mean that anyone should go along with inaccurate and incomplete advice like this either.

    That article talks extensively about Nickel Cadmium (NiCd) cells.....which are not used in ANY hybrid cars.

    Nowhere does it indicate that a Nickel Metal Hydride (NiMH) cell will benefit to any significant degree from the procedures used for NiCd cells. In fact, it says that they are much LESS affected by the shortcomings of the old NiCd cells.

    +1. NiCd had obvious memory issues. NiMH are much less in that regard. You can get some more life from them sometimes, but if they are used properly (not fully charged or discharged) then that is not really worth the effort for most people. That is also why you very rarely see ALL bars for the battery. The only time I've ever seen that is on long downhills and the engine will start revving high as well to suck off as much excess energy as it can to keep from charging the battery as much. It makes sense to not discharge below ~20% since you need the hybrid battery to start the engine.

    So, back to my original question if changing out modules and reconditioning a pack is only a temporary fix, and if a OEM pack is just not possible, what’s the best Chinese cylindrical/prismatic option available?
