How to replace the battery of the auto-darkening welding helmet

Here is a fast guide to help you replace the battery

First, we need to remove the headd band to make room for us to change the battery.

We just need to press the button on the component and hold it, then push or pull the head band to remove it from the helmet.

Repeat this step on the other side.

Then we can see clearly where the battery is, now let’s pull out the battery compartment, we just need to find the right spot to apply our hand.

Okay, now replace the dead battery with the new battery we’ve prepared. The type of the battery is CR2450.

Before we put back the compartment, we need to make sure the positive side of the battery facing upward, this is critical important.

As long as we place it correctly, no need too much force to put the battery compartment in.

Final step, like how we remove the head band, we need to install it back, again, we just press the button, align the band correctly to the component, then push or pull the band in.
