Title: Battery charger/tester...
Post by: gdv on July 27, 2017, 02:31:27 PM: 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

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.
