Questions about this item

Will the 530 mAh lithium-polymer cell need periodic recalibration or replacement?

The 530 mAh lithium-polymer cell is a sealed replacement; no user recalibration is required and it only needs replacing when runtime drops below acceptable levels.

What limits runtime first during continuous GPS tracking on the Watch GT4 46mm?

The 530 mAh / 2.06 Wh capacity sets the hard ceiling for continuous GPS tracking before the watch must be recharged.

Does the battery generate noticeable heat during all-day wear with heart-rate monitoring active?

The 3.89 V lithium-polymer pack runs at low current for typical sensors, so heat stays imperceptible during all-day wear.
