Technical FAQs 4

How accurate is battery current measurement?

If you're able to accurately sense the current draw, and the battery is well-characterized, you'll be able to accurately determine the amount of time remaining before your mission-critical system dies. With careful design, you can measure battery current to within 0.2 percent of full scale.

How do you measure battery capacity?

One of the easiest ways to take the required measurement is by using a multimeter and a simple calculation. mAh. The milliamp hour or mAh is the most common measurement of battery capacity and pertains to the amount of electric current it can constantly deliver to last one hour. Ah.

How do you measure current across a battery?

You don't measure current across a battery like that because an ammeter setting is effectively short circuiting the battery. In this case you were lucky it was only an AA cell. Had it been a car battery you would certainly have blown the fuse and/or destroyed the meter. Current is measured in series with a load. Voltage is measured across.

How do you charge a battery with a buck converter?

To charge the battery, the buck converter is enabled while the first-stage voltage Op Amps and current-sense INA are used to measure battery voltage and charging current of the battery cell or battery pack.
