Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.

I think that, if you have replaced the rechargeable battery in your heart rate monitor, you will need to charge it up for at least 6 hours, before trying to use it.

Rechargeable batteries that have sat upon a shelf waiting to be bought, have that reluctant quality, in many cases, that require their initial recharge be prolonged, even if the charger says they are charged long before the 6 hours are up.

Try it.

Let me know how it turns out, please. Thanks!
