GoPro Hero 13 AEBAT-201 Replacement Battery 3.89V 1950mAh

GoPro Hero 13 — 3.89V Li-ion Replacement Battery (AEBAT-201)

This 3.89V, 1950mAh lithium-ion cell is a direct replacement for the GoPro Hero 13 action camera. It matches the OEM cell dimensions of 40.80 × 33.40 × 13.20mm and drops into the existing battery bay without modification. Voltage and capacity are matched to the Hero 13's power rail spec.

• Hero 13 platform fit: The Hero 13 uses a single-cell 3.89V Li-ion architecture with a BMS that validates cell voltage before enabling the power rail. This replacement cell sits within the accepted voltage window so the camera boots normally without throwing a battery error on a properly conditioned cell.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the Hero 13 body. The BMS accepted the cell, capacity readout stabilised after one full charge cycle, and the protection circuit tripped correctly at low-voltage cutoff without triggering a hard fault state.
• Video mode thermal draw: Sustained 4K or 5.3K recording on the Hero 13 combines sensor, processor, and image stabilisation loads. Run the camera with the door open or a media mod frame to reduce heat buildup on long clips — thermal throttling affects the cell before it affects image quality.

Why the Hero 13 battery percentage jumps or reads 0% on a new cell

The Hero 13 maps its battery percentage display against a stored discharge curve calibrated to the OEM cell. A new replacement cell with a slightly different internal resistance profile can confuse that mapping, causing the readout to skip between values or drop to zero before the camera actually shuts down. This is a calibration gap, not a cell fault. Run one full charge-to-discharge cycle entirely through the camera body — not an external charger — and the BMS recalibrates its curve to match the new cell. After that cycle, percentage readout typically stabilises.

Hero 13 showing dead battery indicator on a cell that still has charge

If the camera displays a dead or critically low battery indicator immediately after inserting a replacement cell, the BMS is reading resting voltage as below its threshold before the cell has had time to equilibrate. This can happen when a cell ships in a partially discharged storage state — around 3.6V — which the Hero 13 BMS flags as depleted. Place the cell in the camera, connect USB-C charging, and hold the power button for three seconds to force the charge controller to wake. Once the cell charges above 3.75V, the indicator clears and the camera boots normally.
