Best Price Square3 X Renata 393 Button Cell watch battery

I have a Misfit Ray that uses this type of battery. The first batteries that came with the device lasted about 5-6 months. I then replaced them with cheap 393 button cells that I found - these lasted about 4 weeks. After talking to Misfit support, they pointed out that the quality of 393 button cells differs massively between brands and recommended buying Renata. They sell these exact type - Renata 393 Button Cells on their US website but not in the UK, so I found these on Amazon. So far my device has been running for 2+ months so looking good. My advice - buy this brand and don't waste money on inferior brands.

This is the second time all the batteries I ordered were flat, although the first time I blamed it on my device. Not worth buying if not fit for purpose!!😡

Perfect for use in my misfit ray, will purchase again.

3 of these batteries are required for Misfit Ray - step and sleep tracker.Seems a fair price.Prompt delivery.
