Replacement battery for Theradome helmets

This lithium-ion cell replaces the original pack in Theradome LH80 Pro, LH80 and LH40 models. It matches the factory voltage of 3.7 V and delivers a rated capacity of 3400 mAh. The pack is built to the same physical dimensions as the original, measuring 68.4 x 18.9 x 18.9 mm and weighing 75.5 g. Safety circuits protect against over-charge, over-discharge, over-voltage and short circuit.

Suitable for owners of compatible Theradome devices

Buyers with a Theradome LH80 Pro, LH80 or LH40 can use this as a direct swap when the original battery no longer holds charge. It is not suitable for users of other hair-growth helmets or devices that require a different voltage, connector or form factor. Anyone needing a higher capacity than 3400 mAh or a different chemistry should look elsewhere.

3400 mAh capacity at 3.7 V

The single figure that decides fit is the 3400 mAh capacity at 3.7 V, which equals 12.58 Wh. This matches the energy rating the Theradome LH80 Pro, LH80 and LH40 were designed for. If your device specifies a different watt-hour value or voltage, this cell will not work correctly.

Questions about this item

How often will the INR18650-1S1P cell need replacing under daily use?

The 3400 mAh lithium cell is rated for hundreds of charge cycles; capacity will gradually drop to about 80 % of its original 12.58 Wh after typical long-term use.

What stops the LH80 pack from running longer on a single charge?

The 3.7 V, 3400 mAh capacity sets the energy limit; sustained high-drain operation will hit that 12.58 Wh ceiling before voltage drops.

Does the battery get hot or draw extra power when the Theradome runs all day?

Built-in over-charge, over-discharge and short-circuit protection limits heat rise; normal operation stays within the 75.5 g pack's thermal design.
