Polar Loop 2 has an internal, rechargable battery. When fully charged, Polar Loop 2 can hold its charge up to 8 days, depending on the usage. For example, if you browse the display a lot or use your Polar Loop 2 for heart rate training, you need to charge the battery more often.

Use the USB cable included in the product set to charge your Polar Loop 2 via the USB connector on your computer. If you want to plug the USB connector to a wall outlet, use a USB power adapter (not included in the sales package). If the battery has drained and the display doesn't light up after plugging in, it may take up to 20 seconds for the charging animation to appear. The display will rotate between the charging symbol and the battery level percentage as it charges to 100%. It takes approximately 90 minutes to fully charge the battery.

You can charge the battery via a wall outlet. When charging via a wall outlet, use a USB power adapter (not included in the product set).
