They cost about $US10-$US11 for a set of 4 with free shipping in USA. They still are a smidge tight IMO, but much better than normal ones. 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! |
