Since the capacity rating on a battery is a marketing tool, ive found that often they dont apply in the real world. (battery capacity used before dead point) / (((circuit load) + (active load x activation time)) x (average)) = run time or (2660mahr) / ((.02ma + (0.5ma x 12hr/24hr)) x 75%) = 13135hr

Configurations batteries come in various configurations themselves. Add to that the many ways that they can be arranged, the number of possible configurations is endless.

A Battery's Lifetime Can Be Measured By A Multimeter, Including A Stopwatch And A Resistor.

The battery receives a brief discharge for a second or longer. It does not show the separators. People use batteries for different purposes, but mostly in cars.

The Load Current For A Small Battery Is 1A Or Less;

The resistor acts as the load, the stopwatch measures time and the multimeter measures the charge remaining. This is the important test for a cars starting battery. A 1700 mah battery would be discharged in 3 hours by 1700/3 =~ 570 ma and in 4 hours by 1700/4 ~= 425 ma.

The Battery Is Also Submitted To Short Duration Charging And Discharging Pulses Of About 2 Milliseconds To Check That The.

Because analog multimeters are not suitable for measuring the voltage of batteries. Connect the test probes to your cell, with the black wire meeting the negative. This battery is putting out 400 amps.

Electrical Parameters Measured Include The Internal Impedance And The Output Voltage Of The Cell Or Battery Pack With Or Without A Load.

Since current flow relates to ohmic value, most cca testers measure the internal battery resistance. How to test a battery with a multimeter: Battery capacity is a somewhat ephemeral concept.

E = V * Q.

This is a simple and inexpensive battery testing setup, best for comparing different batteries capacities, or load testing to check the state of charge. Charge your battery fully to get an accurate load test reading. In short, you can get the exact battery capacity by multiplying how much current the load is draining with the number of hours.
