No, I have not. I wonder what the concern is? Maybe Soviet-era rechargeable batteries are a little sketchy in terms of leakage? Or maybe the nominal voltage of the rechargeables is a little low for the DC-DC converter needed to drive the VFD?

I haven't used the calculator extensively, but it did work and I didn't notice any trouble.
Perhaps I need to exercise it a bit more!

If it's built anything like Russian farm equipment (Formerly Belarus - now MTZ) you'd need a bazooka and maybe some small-scale nukes to hurt it.
