If you don't have a voltmeter or battery monitor installed, it's possible to use a multimeter to estimate your battery's state of charge (SoC). First, you want to make sure that there are no loads drawing current from the battery, and no charging sources putting current into the battery.
With the multimeter correctly integrated into the circuit, turn on the battery power (if there's an on/off switch) or complete the circuit connection. The multimeter will now measure the current flowing from the battery through the load, displaying the value in amperes (A) or milliamperes (mA).
To check the charger’s current with a multimeter, follow these steps: Start by setting your multimeter to the amperage mode that can accommodate the expected current output of your charger. Select a range on your multimeter that is higher than the expected current if you are testing a charger that should provide.
To accurately measure the instantaneous current output of a battery using a multimeter, follow these steps: Prepare the battery and multimeter: Ensure the battery is disconnected from any circuit. This is to prevent any external circuitry from affecting the measurement. Set up the multimeter: Set the multimeter to measure DC current.
If you are happy with the overall condition of the battery it is time to start the tests with the multimeter. When testing a battery you should test both the level of voltage and also the level of current that the battery is supplying.
Connect the red lead of your multimeter to the charger’s positive (+) terminal, usually marked with a “+” or “POS” symbol. The black lead should be connected to the negative (-) terminal, denoted by a “-” or “NEG” symbol. With this connection, the multimeter can accurately measure the charger’s current.
