Special steps need to happen in order to ensure proper measurements are taken without upsetting the normal operation of the unit under test. Measuring sleep currents can often cause problems with units because of the equipment used to measure very low currents accurately requires a large resistor in series with the power supply.
To ensure accurate and effective battery testing, follow these initial steps: Determine the battery type (e.g., AA, AAA, lithium-ion, lead-acid). Check the battery’s voltage rating (usually printed on the battery or in the device’s manual). Note the battery’s capacity, typically measured in milliamp-hours (mAh) or amp-hours (Ah).
Lithium-ion batteries are widely used in electronics and must be tested for safety and performance. Turn the dial to the DC voltage mode. Set the range higher than the expected voltage (typically around 20V). Ensure the battery is not connected to any device. Handle the battery carefully to avoid short circuits or damage.
A weak or dead battery will show significantly lower current. Turn the dial to the resistance (ohm) mode. Attach the red probe to the positive terminal of the battery. Attach the black probe to the negative terminal of the battery. Observe the resistance reading on the multimeter display. Ensure the reading is stable before recording the value.
Turn the dial to the DC voltage mode. Select a range higher than the battery’s voltage if the multimeter is not auto-ranging. Attach the red probe to the positive terminal. Attach the black probe to the negative terminal. Look at the digital display for the voltage reading. Ensure the reading is stable before recording the value.
Usually, you start by turning to a quick and simple formula like the one used in the DigiKey Battery Life Calculator. You will receive an estimation of battery life based on nominal battery capacity and the average current that you assume the load will draw from it.

A load test measures the battery''s power when it''s in use. Higher-end multimeters have 2 load settings, 1.5V and 9V. For a AA, AAA, C, or D battery, set the voltage dial to 1.5V. Set the voltage to 9V for a 9v battery. Hold the black probe to the negative end of the battery and the red probe to the positive end to test the battery''s milliamps.

Properly measuring the sleep current helps to accurately estimate battery life requirements. To ensure that you take proper measurements without upsetting the normal operation of the unit under test, read the following steps.
Use a battery simulator to monitor State-of-Charge, Amp-Hours, equivalent series resistance, open circuit voltage, terminal voltage, and load current. A battery simulator emulates the battery''s voltage drop, ∆V, due to its internal resistance when the load current changes near instantaneously by ∆I.

Hi, I agree with Ironic, measure the voltage across a small resister between the battery and the pic (or between battery and pic regulator if used). As Ironic said select the resistor to get a …
The current draw will also vary depending on network and system activity. You can clearly see a reduction in current draw from the battery as the networks begin to sleep and the parasitic current draw from the battery as it settles at 40 mA for over 21 minutes (sleep mode). The target parasitic drain is < 80 mA and stable throughout.

First prepare the vehicle for the parasitic draw test by making sure the battery is charged. Weak batteries don''t give accurate results when performing a draw test. In addition to diagnosing and charging a weak battery (or if you installed a new one to replace a dead one) make sure to verify that the charging system is operating properly. 2. Turn the ignition OFF, and then make sure all ...
Place the battery on a flat surface and check that no bulge has formed on the surface of the battery. Doming of the battery is the result of overcharging.
