How to Test AA Batteries with a Multimeter
If your battery is fully charged, the voltage reading should be around 1.5 volts. If the voltage reading is lower than 1.2 volts, the battery may be dead or close to it. Assessing Battery Health To assess the health of your AA batteries, you will need to measure their voltage under load..
current measurement
Yes, in general, you need to put an ammeter inline with the circuit to measure current. If your "simple voltmeter" is actually a multimeter, then it likely includes an ammeter which will do the job. Multimeters are very inexpensive. It''s possible in some cases to deduce ...
