Two-Pack Replacement Battery

This two-pack supplies lithium-ion cells rated at 1900 mAh and 7.3 Wh for GoPro HERO 12, 11, 10 and 9 Black cameras. Each unit matches the ADDBD-212, ADBAT-001 and ADDBD-001 part numbers so action-camera owners can keep shooting without hunting for a wall outlet.

Built-In Safety Circuit

The packs meet UL 1642 and CE requirements and include protection against over-charge, over-discharge, over-voltage, over-current and over-heating during normal operation. Voltage sits at 3.85 V so the camera’s power management sees the same profile as the original cell.

Sustained Recording Sessions

Under continuous video capture the higher capacity extends run time compared with lower-rated alternatives and the protection circuit prevents thermal shutdown mid-session. Users who need all-day recording on a single swap will benefit; buyers needing more than two spares or a dedicated charger must look elsewhere.

Questions about this item

How do I install these batteries in my HERO 12 Black, and what step do people often miss?

Open the battery door, insert the 3.85 V 1900 mAh cell with the contacts facing the camera, then close the latch until it clicks; the step often missed is fully seating the latch so the waterproof seal engages.

What maintenance or replacement will this 2-pack need over time?

The lithium-ion cells have built-in over-charge, over-discharge, over-voltage, over-current and over-heating protection; when run-time drops significantly after many cycles, replace the pack.

What limit appears first during extended recording with these 7.3 Wh batteries?

The 1900 mAh capacity determines recording duration; once the charge is depleted the camera powers off, so carry the second cell for continuous shooting.
