Battery charger/tester...
« 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'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.
