HRM-Pro bad after 8.10 update?

might be worth posting here

forums.garmin.com/.../accessories-sensors

thanks, you are right.

Hi, I already posted there. I checked and everything looks very clean inside, even left the battery out for one hour, but after that still bad HR data. I have already packed the HRM and is back to be replaced in warranty where I bought it from. They will check it and report back to me. I will let you know if there is anything than a faulty device.

here is one workout, for the first 3 min the HRM reported some very low HR than I disconnected it and used the wrist HR, but you can see how low the data was considering I was rowing moderately.8578091244_ACTIVITY.fit.zip

I have two HRM Pro and they both work fine after the 8.10 update. 

Hi Meste,

I read that you replaced the battery in your Gen 1 MARQ by yourself  :)

Since I will be attempting it as well, may I ask what type of battery you ordered and perhaps from where?

And apologies for bothering you here but I got a MARQ question for you and the MARQ Gen 1 forum has been archived.

All the best,

M

Hi Mandini, i ordered the exact model for fenix 5 from aliexpress write me to my email and send you more info (serbanmeste at gmail.com)

Thank you Meste, that is very kind of you. Email sent. 

Hi,

I’m also interested because the one I tried with my Fenix 1 was a total failure.

The vendor announced as new but it was used and it only charged to 70% and it going down like a rock …

Worst was Alliexpress . I opened a dispute but the result was sending the battery back… Turns out the freight was more expensive that the battery …

Tks.

PS: I’m just looking for a trustable store…
