Owners of the listed Theradome models needing a fresh 18650 cell will find a certified, tested match here. Buyers whose device uses a different form factor, voltage or connector should look elsewhere. The pack is sold as a single unit, so systems requiring multiple cells are not covered. No charger is included.

Questions about this item

Should I choose the LH80 Pro, LH40 or LH80 version of this 2600mAh 18650 battery?

At 3.7V the cell stores 9.62Wh, giving the original runtime the Theradome LH80 Pro, LH40 or LH80 was designed for.

What interface or standard does the INR18650-1S1P cell use, and what does it cap in practice?

It is a standard 18650 lithium-ion cell with built-in protection against overcharge, over-discharge, over-voltage and short circuit, limiting voltage to 3.7V nominal.
