I am looking for a battery charger/tester where I can check the mAh of the batteries...
Sizes mainly would be AA, AAA, 18650... Place for a 26650 would be nice, but not essential...
Suggestions? Couple of units recommended via internet were... the OPUS BT-C3100... & the NiteCore Intellicharger D4
TIA,
George

Get a El cheapo multi meter.

I've never seen a multimeter that measures mAh.

I am not aware of a charger that tests or the reverse. Two purchases may be necessary. I find multi meters at garage sales for a couple of bucks.

A multimeter, a low resistance -high wattage load and ohms law. The load will be the hard part. I am not familiar with those numerical battery models but Google Indicates they can crank out 30 amps. A 1 ohm power resistor (highest wattage you can find) and maybe submerged in non conductive oil or fan cooled will help.
