Build a Battery Internal Resistance Meter with Arduino and Atmel ATtiny85 IC In an ideal scenario, a battery should have zero internal resistance. But batteries are not made perfect and the electrodes are not 100% conductive, which creates a small resistance within the battery called internal resistance. Practically batteries will always have some internal resistance. On paper, the value of the resistance will appear low around 0.1Ω for… |
