    So, has anyone dissected these newer modules? Are the studs threaded in, or attached some other way? Any chance I could remove them and replace them with something that'll function? Maybe take studs from the old modules to replace them with?

    Do not attempt to repair those modules. It is not worth the risks. The terminals are riveted in. Here's a good example of what can happen when a battery is not properly assembled.

    If you are fairly strong, then you could likely achieve 48 in/lb with a screwriver. (might need both hands for 60)

    Point taken and will not pursue. Thanks for sharing the pix.

    Can you suggest a source for buying Yabo modules for the USA?

    As suggested in post #10, get some modules from @TMR-JWAP

    That'll be my next move if I can't find new 3rd party modules.
    1. I struck out with the dealership, so no new Toyota modules, which would have been the first choice.
    2. Looking to get new non-Toyota modules as the next choice, as it was said, yes, "they are crap, but better than any used modules". And if I can't locate/acquire, then...
    3. Third preference is to get the best used Toyota modules (newest, fewest hours, characteristics closest to new Toyota modules), and I'm happy to consider suggestions like yours, as this is all greek to me (I have no expertise in this and am appreciative of the wisdom of the forums).

    Thanks for the recommendation.

    So, I have a genuine Denso SK16R11 sparkplug rated for 100k miles. For whatever reason, I remove it after 5k miles, clean it and put in on the shelf with 20 other various used genuine Denso plugs. Since it's now used, am I better off buying a Chinese counterfeit and install it, because it's new and it must be better than any used sparkplug. What if I had a way of marking those used Denso plugs so I know which ones only had 5k miles?

    I have a flashlight and just put 3 new Energizer D cell batteries in it. I used it for 3 minutes to look for a dog toy under the couch. I removed the batteries and put them in a drawer with 20 other used D cells. Next time I need it, am I going to run to the Dollar Store and buy a pack of Dollar Store Chinese D cell batteries because they're new and must be better than any used D cell. What if I knew which of those used batteries had 3 minutes of use?

    Several salvage yards near me have a wall full of used 12v batteries available for about $35 bucks each. We can buy the cheapest 'value' 12v battery that has a one year warranty. (walmart special) It's new, so it must be better than any used battery. I sure wish we had a way of testing those used ones to find the diamond in the rough.. Oh wait, we do. (for me, it's a OTC 3183 electronic load tester).

    When you find someone selling new Yabo modules in small quantities, let me know. I'll purchase some also. I'll throw them on the test bench and see how they compare to the OEM modules. That info is probably out there somewhere, but it's always interesting to see it first hand.

    You can probably find newish modules (2018+) on ebay. Last time I saw ones that were ~1 year old, they were advertised for about $80 each give or take a little. If you're focused on the "year" instead of capacity, just make sure you get an actual serial number so you can decode it to a manufacture date. People sell modules as 2004-2018 (etc) all the time, but they could be from a 2004 or any other year. The serial numbers don't lie.

    I think I understand the point you're making. I'd prefer to take this off-forum to a PM/Conversation, but I can't seem to initiate a conversation. (If I click the start a conversation link under your username, I get a "page not found" and a suggestion to start a new thread, which doesn't sound right.)

    One point about the replacement modules that has not been addressed is State Of Charge. Your brand new pack had 28 modules with a matching but unknown SOC. TMR-JWAP can charge the replacements to any level desired, but it will just be a guess to match your pack. All modules also self discharge over time. New modules self discharge slowly. This makes matching the SOC a moving target.

    Great to point out, thanks. I have a VOM to read static values, but no idea if that's helpful? I have an external charger I could hook up and test over time or read stationary max. Guess I could wire a load and that to testing? Any advice welcome. Again, thanks.

    You need to buy them from China and import them. With DHL you can have them in a week.
