Bar the flat top and the button top issueFrnc wrote: ↑Wed Feb 15, 2023 6:58 pm Had an annoying day. Phone carrier swap had a few glitches. Had to do a Network Reset in the end.
Then I got some 18650s and they were longer than my old ones and got jammed in my radio. Had to poke a screwdriver in and risk damaging them. Bent one of the springs. They go in but a very tight fit. Was hard enough getting the old ones out. I guess they'll do as spares. Two batteries cost half as much as the radio!
I've tied a quadruple lenth of strong thread in a loop around each of the original batteries before pushing them in the radio, makes getting them out a lot easier. One loop per battery. I let the excess thread dangle out under the battery cover so it doesn't fall down the small gap at the side of the battery.
So - when buying 18650s, bear in mind protected can be several mm longer. Mine are 69.8. 65 is the 65 in 18650. 18 is the diameter. Mine are 18.5.
Also there are flat top, button top, and another kind I think!
Protected cells have a little PCB at one end hence a little longer the none protected ones don't therefore shorter length
