peltor tac 6, battery question

so a friend of mine in the military just hooked me up with a set of peltor tac 6’s. now one side works fine but i guess the battery is dead in the other side. can anyone tell me how and where the batt. compartment is located so that i can remedy this. thanks in advance.

you need to remove the ear cushion assembly and the foam baffle from each cup

Next to the knob where the muff connects to the wire headset, you can see a small space (bout a 1/4") on the plastic under the foam.

Stick something in there (penny or pocket knife) and twist to pry the two halves apart.

what type batt’s. that seems like alot of work. thanks.

AAA

I never noticed the notch…:o

got it taken care of. thanks guys.
