Three-pack for HERO 9 10 11

This three-pack supplies replacement lithium-ion cells built for GoPro HERO 9 Black, HERO 10 Black and HERO 11 Black cameras. Each cell delivers 1900 mAh at 3.85 V, matching the original ADDBD-211, ADBAT-001 and ADDBD-001 form factor. Photographers and action-sport creators can keep shooting without waiting for a single battery to recharge.

Steady output during long sessions

The 7.3 Wh rating represents usable energy under continuous draw rather than a brief burst figure. Built-in protection circuits guard against over-charge, over-discharge, over-voltage, over-current and over-heating, so voltage remains stable during extended 4K recording or time-lapse capture. Cycle life benefits from the consistent current management.

Compact cells with multi-layer safety

Each battery measures three by two by three inches and meets UL 1642 and CE safety standards. The three-unit pack lets users rotate cells through the camera and a charger, reducing wear on any single pack. No extra cables or adapters are required; the cells slot directly into the camera battery compartment.

Questions about this item

How much heat does the 3.85V lithium-ion chemistry generate during all-day shooting?

The 1900mAh cells include built-in over-heating protection that activates before temperatures reach unsafe levels, so extended recording sessions stay within the safety envelope defined by UL1642 and CE testing.

Which original GoPro battery part numbers must I already own for these replacements to fit?

These packs are direct replacements for GoPro ADDBD-211, ADBAT-001 and ADDBD-001 batteries used in HERO 9, 10 and 11 Black cameras.

Will the 7.3Wh capacity work with the dual-battery charger I use for my HERO 9?

Yes — the voltage and chemistry match the original ADDBD-001 specification, so existing GoPro dual chargers recognise and charge each 1900mAh cell normally.
