Product details

AccuCell Battery – compatible with Garmin Fenix 7X Solar, Li-Polymer, 3.8 V, 550mAh, 2.1 Wh

Product Overview
The AccuCell replacement battery is a high-quality replica specifically designed for the Garmin Fenix 7X Solar. It impresses with the same electrical specifications:

  • Battery type: Li-Ion-Polymer (Li-Po)
  • Nominal voltage: 3.8 volts
  • Capacity: 550 mAh (2.1 Wh)
  • Dimensions & weight: matches the original battery, including integrated connector, dimensions approximately 36.2 x 25.3 x 4.0 mm, 7.28 grams

It is not an original part from Garmin, but a compatible third-party battery – ideal as a secondary or replacement battery when the original battery loses power or no longer functions.

Why a replacement battery?

  • Battery performance over time: Li-Ion batteries lose capacity with each charge and discharge cycle – often noticeable after 2–3 years.
  • Cost efficiency: Significantly cheaper than a Garmin service battery replacement or purchasing a new device.
  • Sustainability: Extends the lifespan of your Fenix 7X and reduces electronic waste.
  • Full compatibility: The AccuCell battery can be easily used with the original Garmin charger as usual.

Installation & Notes

  • Tools & instructions: Requires disassembly by removing the back – ideally with special watch case tools.
  • Compatibility: Ensures identical technical specifications as the original (voltage, capacity, connection).
  • Safety note: Battery free from hazardous material classifications – however, caution is advised during installation (avoid short circuits).
