Insert the rechargeable battery in the battery holder; when the rechargeable
battery cell is fully charged. The LED lights up. Now push the button. The LED will
darken slightly. With the 100 Ω resistor, about 15 mA of load current will ow. This
is easily possible for the rechargeable battery. Therefore, the rechargeable battery
voltage will only drop slightly.
13.2 Test at High Current
Test setup: Plug board, red LED, resistor 1.2 Ω, battery holder, rechargeable
The tests can be performed with different rechargeable battery types as well
if you have a multimeter with which the rechargeable battery voltage under
load can be displayed.
The test at higher current is a bigger challenge for the rechargeable battery.
Observe the maximum discharge current to be applied to the rechargeable battery
without damaging it. In lithium rechargeable batteries, it is usually a current of twice
the capacity, in nickel-zinc rechargeable batteries, the recommendation is: do not
discharge any lower than to the voltage of 1.2 V and at no more than 1C.
