    Installed these last summer and never seen them flash:thumb: so happy travelling and easy checking:thumb:.

    Over winter the tyre pressures have dropped quite a bit, 5.50 down to 4.90 for example, this seems quite normal as it's been stood for a few months. As the LEDs weren't flashing I can only assume that they have triggered and run the batteries down to zero.

    Is there a way of testing the batteries, or is it a case of trying to simulate a pressure drop to see if there is any battery life ?

    Also from memory you can't change the batteries, is that correct ?

    In this case then I'll need a new set:Sad:

    How did you check your pressures? you'll lose some air simply by unscrewing them.
    I'm happy that mine are holding fast and I have a keen eye for a correctly inflated tyre.

    BTW I would use psi rather than bar as more increments give better accuracy

    The LEDs will flash for a full week or more, yes you can test them with the tester we gave you, it's a small extension, however it is fiddly. Bring them to any show or rally and I'll test them for you and change the batteries if necessary :thumb:

    I used a digital tyre pressure gauge and agree that you get some air release when you unscrew them although not much. Why BAR ? well only because it's a global standard and some countries have yet to catch up:Laughing:

    Argh that little gizmo tool that came in the packet with them…… got to end it now:Doh:

    Any other way to check them without the tool ?

    Yes side impact screwdriver :Rofl1:

    With a figure of 0 to 80 psi I prefer 80 increments

    With 2 decimal places in metric BAR testers I prefer 999:Wink:
