The HRM-Pro Plus uses a standard CR2032 coin battery and Garmin lists the battery life at 12 months if you train for an hour a day, the same as the HRM Pro. I trained a little more than an hour a day on average and needed to change the battery on the Pro every six to seven months.

Unfortunately, the pod is not recognized anymore by my watch. I tried deleting the pod from my watch (FR735XT) and searching for it again (while walking around with it), but no luck.
