I was asked to if possible post some scope screens from a C204W charger cycle. These were done using two AA cells, so the maximum current is 2A but again this is another PWM cycled charger! It appeared to be the best way to show the cycle was to plot the duty cycle, so all five screens are showing duty cycle. Whatever the percentage it is that part of 2A. The first four are zoomed in traveling from left to right each one overlaps a bit. The last screen is after the charge LED turned green and it was in trickle mode which lasted around two hours(8% or 160ma) and although I don't have a screen of it, the current dropped to around 130ma, still PWM. It slowly alternated between 60ma and 130ma.
For a charger that claims high initial currents to shock or jolt a old cell it starts off rather wimpy at around an effective .5A and stays at 1A for some time!!
I remember testing this charger for cell temperature and it got over 140F but most of that heat must be generated by the built in power supply, etc. The cells ran much cooler because the cells were extended outside the charger for this test.
