Garmin HRM-Dual not working

Garmin HRM-Dual not working after less that 1 year. Should i change the battery? The spec states battery should last about 2-3 years. Any advice?

    Have tried this twice now after battery replace (with two different batteries). Edge 530 sees it, but never connects..  Going to shop some other brand HRM now.

    Bought a Polar and it just keeps working like a charm. Connects instantly, even to multiple devices at the same time with no issues at all.
    A true delight.

    Ultimately the HRM-Dual didn't work for me after all, so I purchased the Garmin HRM-PRO + and have had zero problems with it using both an Edge 830 & Forerunner 745.  In fact the running metrics it provides are terrific.

    Adding a new battery did not work for me.  It wasn't until after I did the reverse polarity reset did it finally connect and work fine.

    I had the same problem. Android phone Bluetooth finding the sensor but not transmitting data. Solved the problem by resetting Phone's Wi-Fi, mobile networks and Bluetooth (search this action in phone's settings)

    So happy this worked (flipping the battery) was just about to buy a new one. Thanks. :-)

    Just to be clear, flipping the battery didn't help in my case.

    Bought an HRM-Dual together with a Concept2 rower. Ant+ module works fine, but the BT module connects but won't send data. And this was out -of-the-box, Day 1 of ownership. Day 2 of ownership was spent at the local service center, figuring out the issue. Managed to confirm the BT module of their demo unit connects to Polar Beat (connects + transmits heart rate data), while mine connects but does not transmit heart rate data. Regret buying this over the H9 I wanted to buy (wasn't in stock). Had bought the dual anyway thinking I might buy a forerunner in the near future - well, forget that. RMA'ed the dual through the original vendor (service center said they might need weeks to sort out the replacement due to mine not being a local unit), but went ahead and bought a polar. When the dual is replaced, I'll keep it as a spare or sell it. My advice? Avoid this product.

    Hi people

    I do not understand how can the reverse polarity work if turning the battery up side down there is no contact in the + area ? Both metal contacts will only touch the - area.

    Please advise
