When the minimum charge current termination method is used and no battery is present, a sawtooth waveform of several hundred mV p-p will appear at the charger output. This is a function of the output capacitor and the charger output cycling between the recharge threshold voltage and the float voltage. The sawtooth frequency is dependant on the value of the output capacitor. With a 2.2μF output capacitor, the frequency is approximately 40Hz, which will cause the CHRG LED to appear dim. With a larger output capacitor, the LED will flash briefly.
