"Yaesu VX-6 battery pack (FNB-80LI) rebuild"에 답변The only difference was that my radio is a Yaesu VX-7R. But will be basically the same procedure for both radios. Slowly and carefully keep slicing until you have gotten thru. And not too deep. That’s what I did was with my power supply set to 3.7 volts I held on to the terminals on the battery, not the connections for like 30 - 40 seconds (You have to go direct to bypass the board.) Until I got somewhere like 3 volts in the battery I did it with both of them. Then put back gasket attached to the radio and now charging on the screen. And now you have working batteries, without replacing. And it will work on all your electronics with rechargeable batteries as long as the batteries have some life in them.
