A multimeter doesn't put any load on the battery.
A (decent) tester will have an appropriate load for the type of battery of about 0.05 to 0.1C, so for a 2200 mAh AA NiMH, about 110 mA to 200 mA. 10 - 12 ohm resistor for 1.2V nominal.
This shows you the cell's internal resistance, an increase of which is a sign of impending doom for a battery.
If you use your batteries at high currents, test at those currents.
- horsawlarway 3y agoSure - but a multimeter also doesn't require the battery to be inserted into it - you can test the voltage while the battery is under load in most devices. Not saying you can't buy a really good dedicated battery tester if that's what you want - but that dolla-fiddy version from ebay ain't gonna be it :)
