Our take on the CS-THL400XL : Battery for Theradome LH40, LH80, LH80 Pro - Replaces Theradome INR18650-1S1P

The CS-THL400XL is a single 18650-style lithium-ion cell built to replace the Theradome INR18650-1S1P battery in the LH40, LH80 and LH80 Pro laser helmets. It is a 3.7V, 3400mAh cell measuring 68.4 x 18.9 x 18.9 mm and weighing 75.5 g. The 3400mAh capacity is at the top of what a standard 18650 cell offers, so runtime should match or beat the original cell when new. It suits owners of a Theradome helmet whose original battery no longer holds a charge and who are comfortable opening the unit to swap a cell.

Questions and answers

Will this battery fit my Theradome helmet?
It is listed as compatible with the LH40, LH80 and LH80 Pro and replaces the INR18650-1S1P part. Check your helmet's original part number before ordering.
How does 3400mAh compare with the original cell?
3400mAh is a high capacity for an 18650 cell. Expect runtime similar to or better than a new original battery, though age and charging habits affect real results.
Is it the same size as the original battery?
It measures 68.4 x 18.9 x 18.9 mm, the standard 18650 form factor the Theradome helmets use. Confirm clearance inside your model before installing.
Do I need special tools to install it?
The battery ships as a bare cell. You will need to open the helmet and reconnect it yourself, so some soldering or connector work may be required depending on your unit.
Is it safe to replace a lithium battery myself?
Li-ion cells can short or overheat if mishandled. If you are not confident working with batteries, have a repair shop do the swap.
