A value of 12.2 volts is about 50 percent, which means readings of 12.2 volts and lower indicate a bad battery. Once you''re done checking your battery state, remove the negative terminal first.
The open circuit voltage of the battery can also be measured and the voltage drop (under load) can hence be calculated. Dividing this voltage drop by circuit current yields internal resistance. A note on the load resistor value of 30.5 ohms is that it was probably carefully chosen as being representative of a "mid-range" AA battery load.
If the battery has a CCA rating, you can apply a load equal to ½ the rating for 15 seconds. The voltage should stabilize above 9.6 volts while on load. To apply a more determined test, you …

An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [2] The terminal marked negative is the source of electrons. When a battery is connected to an external electric load ...

Please consults with the battery documentation for its exact value. Maximum short-term battery load, W – the approximated recommended wattage the battery should handle within a very short period, e.g. a couple of minutes. However, in the range of several seconds, the battery can also sustain higher loads. This is the so-called "surge ...
R1 and R2 appear as one ohmic value. The two-tier DC load method offers an alternative method by applying two sequential discharge loads of different currents and time durations. ... If it''s a cranking battery, load to 10 times the Ah The 2 tier (fig 4) is far better way to measure internal resistance . On May 14, 2017, Anita wrote:
C-rate of the battery. C-rate is used to describe how fast a battery charges and discharges. For example, a 1C battery needs one hour at 100 A to load 100 Ah. A 2C battery would need just half an hour to load 100 Ah, while a 0.5C battery requires two hours. Discharge current. This is the current I used for either charging or discharging your ...

A battery''s capacity rating (e.g., 100mAh) indicates how much charge it can deliver over time, not the instantaneous current measured in this test. If the measured current aligns with the expected value for the load, the battery is likely in good condition. However, this does not directly indicate the battery''s total charge capacity.
