    Thinking Multimeter with battery load test

    Hi, I looked for an answer to this question and couldn't find.

    I purchased a Innova 3320 multimeter which has a battery load test function. I use it to check the state of charge on 3.7 volt li-ion's. I have read on this forum that I should load the battery with a 10 ohm resistor when testing with a multimeter.

    http://www.candlepowerforums.com/vb/...d.php?t=214963

    Does the battery load test function act as a resistor or do I still need one? If so which voltage should I use? (1.5-6-9-12 ) Thanks for help, John

    With LiIon you do not need a load resistor, just select the 20 volt range.
    For NiMH and alkaline batteries a 1 ohm load resistor is much better than 10 ohm and you use the 2 volt range.

    And might I suggest that you check this guide to use a DMM.
    My website with flashlight, battery and charger information: lygte-info.
    More than 200 battery reviews and 80 charger reviews.
    Compare 18650 LiIon batteries or smaller (RCR123, 16340, 14500, 10450) LiIon batteries.
