HRM Dual stops working mid way through activity

I’ve had my HRM dual stop transmitting heart rate one and half hours into an activity. I know I have a new battery installed. It’s done this a few times already and very frustrating. I move it around and it starts transmission again but a very low heart rate and after few minutes stops transmitting. Anyone with similar experience. Thank you

    I had my HRM Dual  less than a year and suddenly giving me issues. I have done the reset (upside down battery) and everything as advised. then it worked for about two workouts and then again my edge not "seeing" the HRM. so i repeated it all, again replaced with a brand new battery. this morning an hour in to my training got message the HRM battery is low and then just gone. i really take good care of it, make sure i hand wash my strap after each use, wipe off the pod.... really sad considering the cost. I will again try a new battery today but it almost seem like something is draining the battery

    Same experiencee with a HRM Pro plus in combination with an edge 530. Disconnecet during a coffee break, did nod connect again.  Sensor reset, new battery, next day it worked fine until the coffee break after about 2 hours... disconnected, did not connect again. At home sensor reset, works fine again with the same battery.

    Very frustrating during a 100k ride. Please fix the problem!!

    Yes i did resolve it i bought another brand Slight smile tired of struggling like this. plus no light on the device to know if it is even working or not. i got one for half the price of the Garmin and it works really well and come with excellent reviews. totally compatible with the garmin edge as well.

    I am having the same problem, except in less than an hour of exercise, sometimes from the onset.  Tech Support doesn't offer much, only to clean the strap thoroughly once a week and clean the monitor itself after each use.

    I am using mine while rowing on a C2 erg.  I read somewhere on this forum about a HRM Dual update, but cannot find out how to do the update.

    I used an older HR monitor when I ran and cycled, but don't remember it being so particular in cleaning instructions.  

    If you find another solution to the problem please post.

    Yes similar experience.. Very frustrating!!.. I see it happening even more so as soon as im doing CV in seated position..

    Wondering why no-one from Garmin is on this thread advising how to proceed?? (other than the upside down battery reset)

    I got on the phone w Garmin tech.  They sent me a new battery and said if that didn't work they would replace it.  The battery didn't solve the problem and they shipped a new unit.  So far so good, but it takes a good 15 minute warmup before it starts working.
