I have been using one of these winders for several years.  Apparently it was manufactured in Ukraine. It has a built-in torque meter and a battery-powered counter.  It is very smooth and a delight to use, but a little on the expensive side.

I need to replace the battery for the second time.  I am having difficulty removing the battery.  It is one of those coin-style batteries.  I assume you slide it out laterally as there is a clip that holds the battery in place that spans across the upper side (exposed face) of the battery.  The clip does not seem to release or unclasp in any fashion that I can determine.

I am having difficulty sliding the battery sideways. It won't budge.  Am I doing something wrong?

It has been a while since I replaced the battery and I forgot how I did it.

Hopefully someone who owns this same winder will let me know how to solve my problem.  I don't want to break the circuit board.

Thanks in advance.

is that some sort of latch on top of the clip?

Crabby -

Thanks for your input. The clip appears to have a leaf spring formed in the middle of the same, apparently to squeeze the battery in place.  

My wife was able to get the battery out safely.  You have to tip the circuit board and then slide out the battery toward the closer side wall of the compartment for the circuitry. It slides over the upper edge of that side wall.

See the attached picture.

I am still trying to talk my wife into building a free flight model, and in particular, a P-30.  She will go to contests, handle equipment, time my flights, and keep sight lines for me.  But she is not willing to build a P-30!

One of these days I would like to build and fly a vintage coupe.

Have her build a catapult glider or something else that's a smaller project.
