    The CF-VZSU71 is recommended for CF52 mk4 and later, but not the earlier mks
    Why?

    Voltage is lower than the CF-VZSU46. but the CF-VZSU46 will work in all CF52's

    I think I need to do a battery thread for the CF29, CF51 CF52, CF53, CF30, CF31

    A lot of different batteries with different voltages and amperage's.

    What's important is that all of these batteries will physically interchange for the most part..CF29 and CF51 are a tiny bit different.
    but they are not all completely electrically compatible. They MAY work in various mode Toughbooks but not efficiently.

    VZSU29
    VZSU46
    VZSU65
    VZSU71
    VZSU72

    I eliminated the letters at the end of each model.

    You explained why my i noticed my CF-53 i5 is getting such poor performance with the VZSU72 they gave me as a replacement battery. I guess I need to get VZSU71 instead. Thanks for the clarification on the batteries and their compatibility and features.

    In my opinion it is best to get the same model batteries if using more than one and do a recalibration for those batteries voltage and mah ratings.
    I have used a VZSU46, VZSU72, and VZSU65 in the same laptop without recalibration. The laptop gets confused and reacts unpredictably.

    That being said, where do the 29AS fit into the picture?
    Just wondering with a bunch sitting here.

    A VZSU29 battery is designed for a CF 29, CF 51, and early CF 52.

    They do seem to work in a CF 30 and CF 31. Although they have lower run time than a VZSU46 battery
