The 240 mAh battery capacity limits multi-day use when cellular and GPS are active continuously. IP68 water resistance protects against dust and immersion up to rated limits.

Questions about this item

Will the 240 mAh battery need replacement after a few years of daily charging?

The lithium-ion cell is rated at 240 mAh; like all rechargeable batteries it will gradually hold less charge, but the watch is sealed so any replacement requires professional service.

What limits continuous LTE use during a full-day hike?

The 240 mAh capacity and LTE radio are the first constraints; heavy cellular data will drain the battery faster than Bluetooth-only mode.

How warm does the 40 mm case get and does the fan spin when I stream music over LTE for hours?

There is no fan in the 40 mm case; the aluminium body dissipates heat passively and stays comfortable during extended LTE streaming.
