As there is no single analytical device to assess the health of a person, nor are instruments available that can quickly and reliably check the state-of-health of a battery. Like the human body, batteries can have multiple hidden deficiencies that no singular test method can identify with certainly.
A dead battery is easy to check and all testers are 100 percent accurate. The challenge comes in evaluating a battery in the 80–100 percent performance range while on duty. Regulators struggle to introduce battery test procedures. This is mostly due to the unavailability of suitable technology that can assess a battery on the fly.
No practical method exists to quantify all conditions of a battery in a short, comprehensive test. State-of-health (SoH) cannot be measured per se, it can only be estimated to various degrees of accuracy based on available symptoms. If the symptoms are vague or not present, a reliable measurement is not possible.
This Battery Discharge Testing is rock solid, proven and terribly reliable. You can also find resistance connections this way too if you measure voltage drops across the straps. You only have to do that one time at the start of the test. It may be an old fashioned method but it works. Its great learning here, pls keep it up.
Other important tests include safety testing (to make sure the battery won’t overheat or catch fire) and cycle life testing (to see how many times the battery can be discharged/charged without degrading). Both of these tests are essential in ensuring that lithium-ion batteries are safe and reliable.
Battery testing is complex even for the sighted man but progress is being made. Better technologies will eventually immerge. Story of blind men trying to figure out an elephant through touch. The tale provides insight into the relativism and opaqueness of a subject matter, such as a battery.
