Same question. Fenix five /+ guide on the way?

Erik E123 -

Thank you. It saved me around over £100 to change the battery myself. Garmin quoted around £121 for battery replacement for out of warranty watch. I bought the battery around £15 and followed the guide to change the battery myself in my Fenix 3 watch. My watch does not have heart rate monitor, perhaps the ribon at step 5 is for HR monitor as I didn’t have it in my watch. Thanks again for simple, detailed and easy to follow instructions.
