WebApr 26, 2024 · Here are the most common battery test methods: Voltage. Battery voltage reflects state-of-charge in an open circuit condition when rested. Voltage alone cannot estimate battery state-of-health (SoH). Ohmic test. Measuring internal resistance identifies corrosion and mechanical defects when high. WebJan 12, 2024 · 5. Test the battery under load after charging. For AA and AAA, use a resistor of about 10 ohms, or a small incandescent flashlight bulb, in parallel with the multimeter. NiCd or NiMH cells should be ~1.4 volts, though different cell chemistries may give a range of ~1.35 to ~1.5 V.
