Fig. 042 shows the test setup for a very simple charge status display. After setting

up the components, rst connect the lithium rechargeable battery to the plug board

with the alligator clamps. Then the orange LED lights up. Once the USB plug

is plugged into the USB mains adapter, the rechargeable battery is charged at

approx. 200 mA. A short time later, the ashing LED starts to ash and indicates

that the rechargeable battery has reached the voltage of about 4 V. The ashing

LED will rst slow down and then speed up. This indicates that charging must be

terminated at once. A comfortable charger would do this automatically.
