AMIRO AMLO1 INR18650-2 Replacement Battery 7.4V 2600mAh

AMIRO AML01 / AML02 — 7.4V Li-ion Replacement Battery (INR18650-2)

This is a 7.4V, 2600mAh Li-ion replacement battery for the AMIRO AML01 and AML02 LED cosmetic mirrors. It slots into the mirror's battery bay and powers the LED lighting system used for makeup application and grooming. Capacity figures come from the product data — 2600mAh / 19.24Wh.

• AML01 and AML02 compatibility: Both mirrors run the same 7.4V two-cell Li-ion architecture and share the INR18650-2 cell format. The LED driver circuit and BMS handshake are identical across the two models, so one battery covers both.
• Bench tested on actual hardware: We ran this cell through the AML01's LED driver under full-brightness load. The BMS held the output rail steady across the charge cycle and tripped correctly at the low-voltage cutoff without flickering the LED string.
• First-charge calibration on install: After fitting this battery, charge it fully before switching the mirror on. The LED driver reads cell voltage on first use to calibrate its constant-current output. A partially charged cell at first use can cause uneven light intensity across the LED ring on that initial session.

Makeup mirror LEDs dimming before the battery indicator shows low

The AML01's LED driver runs a constant-current circuit, but that circuit has a minimum input voltage threshold. As the cell voltage sags under full-brightness draw, the driver starts reducing current to the LED string before the battery indicator triggers — so the light dims while the gauge still reads mid-charge. This is voltage sag under load, not a fault. Switching to a lower brightness mode reduces draw and stabilises the output rail. If dimming starts early in a session, the cell is likely worn and no longer holding its voltage curve under load.

Mirror not charging via USB after battery swap

The AML01 charging circuit requires a USB adapter that can sustain its minimum input voltage — a low-output or worn cable often drops below this threshold and the charge IC never activates. Swap to a wall adapter rated at 5V/1A or higher and check the cable for damage. If the mirror still shows no charge activity, confirm the battery is seated fully and the connector is latched — a partial connection prevents the BMS from completing the charge circuit. A properly connected cell on a stable 5V supply should trigger the charge indicator within 30 seconds of plugging in.
