My usual practice is to remove batteries from most electronics when not in use, unless it is a life-saving device or not practical to remove them... but a couple months ago I discovered a couple batteries I had stored with an Aimpoint (removed) and found both batteries had leaked in their individual storage spaces in the box.

I decided that my MSA Sording Supreme Pro-X might be at risk leaving the batteries in them and decided to remove them when not in use.

The Supreme Pro-X instructions are somewhat vague but describe installing the bottom battery as simply slipping it into the compartment and then shaking it until it falls into place. My bottom battery fell part way down into place but my inserting the top battery in it forced the bottom battery into it's proper location. The instructions state that the process is the same for removal.

The batteries are in a stacked arrangement with the top battery in line with the removal cap and once the cap is removed the top battery is free to slip out...however the battery underneath it is held in place by the spring tension of the contacts and that battery is not easily accessible.

I've tried holding the unit upside down while shaking the unit as hard as I felt was appropriate for high end electronics as well as tapping on the earpiece with a plastic handled screw driver...no go.

I've tried prying the battery out with long screw drivers, short screw drivers, wooden popsicle sticks, a lollipop cardboard stick, various swizzle sticks, I even used a Starbuck's coffee cup plastic hole plugger/swizzle stick. The battery is tucked far enough down that I can't get any good contact to either pry up or push the battery back far enough to leverage it up and out...the best I've managed is to nick up the vinyl coating on the battery.

Any ideas on how to remove the bottom battery?

I have the DEHP TC1 headset which is the same housing with different electronics, but the technique should be identical for battery removal.
I have to hold the headset cup in one hand and with the other hand I give it a healthy smack. The second battery usually pops down so that it can come out. Sometimes a second or third smack is required. I know that they are electronics, however I feel these are made for tough duty environments and can withstand much harsher treatment than a few smacks of my hand.

I've also done the smack method with mine. Some good taps on a wooden bench should do it, too. If that STILL won't work, your battery may have leaked and gotten crusty.

Any chance of that?

The guys at SRS Tactical do great repair work on Sordin muffs. I've used them in the past. You could give them a call or send them in as a last resort.

Invert, tap (lightly) on hard surface. This has worked for me for over seven years.

Success! It took 3 full force smacks with the heel of my hand, a lot more force than I feel comfortable applying to electronics, but the bottom battery finally popped out.

I first tried the Allen wrench trick thinking it was certain to work...but the battery was wedged in the compartment tight enough and there just wasn't enough clearance to turn it and get any leverage.

Thanks everyone for all the input!
