    Well there you go. Everything you need for a Gen 2, plus ten spare modules.

    Maybe it is a supply chain issue and there is currently no stock in the system. Maybe it will become available again in the future.

    That may just be a side effect of an upcoming part number change, or some other issue with the price file exchanged between Toyota and the third party (SimplePart) that operates parts.toyota.com. As I recall, the HV batteries for fourth-generation Prius cars were listed as “No Longer Available” for a while, too.

    As I’ve written before: I wouldn’t assume that any part has been discontinued until a Toyota dealer parts department—with access to Toyota’s actual parts ordering and inventory system, for which I’m not aware of a publicly-available interface—has confirmed this in person or by telephone or e-mail.

    Has anyone tried to buy one lately?

    Do they use gen2 modules in new gen1 packs? Gen1 module will not last long with double the current.

    It would say out of stock, possibly Electroingenieur is right about part number change but I would expect introducing new one before removing old.

    What is this double current that you speak of?

    This is interesting. I wonder if the cells in this pack are higher capacity?

    FYI, the Gen 2 oem Toyota battery I bought and installed last week utilizes gen 4 (NIMH) cells.

    It is about math, gen1 have lower power but higher voltage battery than gen2. In result gen1 battery current is in +-100A range when gen2 need pull up to 200A to cover higher power under lower voltage. For this purpose gen2 cells are redesigned with improved heat dissipation and stronger links between cells in the pack.

    Interesting. What is your source for these numbers? It doesn't really resonate with me particularly as a Gen 2 HV battery is 35% smaller than the Gen 1 so it seems strange that you're claiming a 100% difference for the same power.

    Wouldn't the lowering of internal resistance (which they did) be more of a factor than a specific current? This combined with a 35% smaller battery doesn't seem to stack up with what you're saying.

    Can you elaborate on how you can tell the difference between Gen 4 and Gen 2 modules?

    I’m the original owner of an ’04 Prius (Gen2) with almost 200,000 miles on it. The hybrid (traction) battery is failing and I’m wondering whether to sell it as is, or fix the battery. I’d like to repair it, then driving it longer, but it’s not worth it if it means driving an unreliable car. I’ve read too many horror stories of battery repairs or replacements that fail, and mechanics that don’t stand behind their work.

    Is there someone honest & knowledgeable in the LA area who can repair or recondition my battery? I can assist as necessary if that would be helpful.

    Additional question: How much will the resale value of my Prius decrease due to the impaired battery? Will a repair or replacement offset or more than offset the cost of fixing the battery?

    Thanks for your time & interest!

    Gen1 electric motor is 33kW, nominal battery voltage 273.6V so need 120A for max power but I never seen that much, gen2 is 50kW with battery voltage 201.6V, this make 248A but again never seen that high value.
    To be honest I don't see any significant internal resistance improvement, even so in result it will waste less power on battery heating. I'm too lazy to calculate actual power difference but for sure this is not 17kW.
