Replacement Battery for Theradome Devices

This 3.7 V lithium-ion cell delivers 3400 mAh and 12.58 Wh, matching the original INR18650-1S1P specification. It is built for the Theradome LH40, LH80 and LH80 Pro personal-care systems. A decoded chip ensures communication with the device exactly as the factory pack does. The pack measures 6.84 in by 1.89 in by 1.89 in and weighs 50.5 g.

Compatibility Check Before Ordering

Verify that your device model is LH40, LH80 or LH80 Pro and that the original battery carries part number INR18650-1S1P. Confirm the connector orientation matches the replacement before fitting. A new cell reaches full capacity after two or three complete charge and discharge cycles. Avoid low-quality third-party chargers, which can reduce service life.

Sustained Use Behaviour

The integrated protection circuit guards against overcharge, over-discharge, over-voltage and short-circuit events during extended sessions. Operating temperature must stay below 60 °C (140 °F) to maintain safety and longevity. Do not disassemble the pack or expose it to fire or water. Shock-absorbing foam in the packaging protects the cell during transit.
