  • How to Check AA/AAA Alkaline Battery Using a Voltmeter

    Awesome - I want a multimeter that applies a load during testing! What kind do you have and do you remember where you found it? I ask people at hardware and electronic stores if testers or meters that apply load during testing exist, and they don't even understand the concept, let alone know if and where those might be in the world.And when I search online, I must not know what search terms to use, because I've found nothing.Thanks!

    "If in doubt-throw it out!" UNLESS you're one of those weirdos like me who is concerned about things like not being wasteful, not polluting, caring for the environment, caring about other people and stuff like that.

  • How to check AA/AAA alkaline battery using a voltmeter

    Hi Jerry & msurguy - thanks for the tips!Do you happen to know if there are any resistance/resistors inside the ol' Radio Shack battery testers (mine is pictured here w/"Radio Shack" label, but nowadays new ones may have"Enercel" label on it)? If so, how much resistance?I'm wondering if these Radio Shack battery testers put any load on the battery when testing.Thanks!p.s. I keep trying to Finalize this Reply, but nothing happens when I hit the "Reply" button, so THIS Reply effort will now be withOUT the attached picture I mentioned above. If this goes through, I'll try a follow-up WITH the picture again.

    Thanks for the Joule Thief mention, Ujwal - I'd never heard of those, but just read about them online now. Do you know where I can purchase an already assembled Joule Thief led light? I'd love to use my alkaline batteries until they're way more drained!Thanks,Ted
