Replacement battery guide for the Fourier GR-1 — specifications, buying advice, and safe replacement.
Fourier has not published battery specifications for the GR-1 research humanoid. Labs typically source spares through Fourier's research sales channel.
If your lab runs GR-1s, keep a spare pack in rotation — research uptime depends on it. Verify the revision against your unit before ordering; research platforms iterate frequently.
Always match the exact model and revision — Fourier packs are not interchangeable across models. Buy OEM wherever possible; the battery management handshake is model-specific. For installation help, find a technician experienced with Fourier hardware.
Check current listings from sellers, or look up the official charging guidance before you buy.

Batteries are the riskiest component to go third-party on — wrong voltage, missing BMS communication, or poor cells can damage the robot or create a fire hazard. OEM packs are strongly recommended.
Runtime drops well below the original spec, the robot shuts off under load despite showing charge, the pack swells or runs hot, or charge times stretch far longer than when new. A swollen pack is a safety issue — stop using it.
