tmart0828

Use the battery tester to see the batteries are empty or not, and to see the volt of the batteries. Throw away dead batteries and keep good ones. Price is decent:US $2.99 (AU $3.31)

The $1 BT-168 battery tester is different from this one. This one can show the volt of the battery with LCD screen!

    The battery tester looks pretty cool. No messy cables.

    this for B.J. Tmart or?

    • what is B.J.?

      • Bob Jane Tyre Mart.

          I tried to fit a tyre between mine and broke it!

          Damn you to heck!

  • oops double

  • Looks good ordered one. Then remembered that I didn't use your discount code…doh..
    Paid $5.51 !!

    • why?

      • +4

        Because I liked the gadget so much I excitedly went to the page and clicked buy, then went back here and saw the discount code…

        • I've done that so many times on Ozbargain deals.

        • @E4xtream:

          I'd say he is in good company, I too have done that more than once over the years.

  • It's a shame it can't test 18650 :(

  • DMM FTW

    • +2

      Digital multimeters do not test cells under load. They're not very good for testing batteries.

    It doesn't allow you to use coupon, it is AU$5.51

    • Do you go to the Secure Checkout to enter the coupon?

      Pay by paypal, and before you reach the "pay now" screen it takes you back to Tmart where you can enter the coupon.

      $3.31 AUD delivered.

      • Thank you. Purchase completed.

  • Thanks, can't wait to get it!!

  • Came out as $3.31 AUD delivered. That is 35 cents cheaper than eBay:

  • The nature of the sliding Negative contact suggests this would a!so be able to test (ie, measure voltage of) LiIon batteries (with 5-digit nomenclatures, as are now in, eg, new Tecsun portable shortwave radios, etc. (eg, 18650's, from memory).

    • Nope, not for testing lithiums. See comment below.

    • I can confirm that a 18650 cell is unfortunately too long for this device. However I hacked the end of the case so that the red slider doesn't stop, so with the slider's end hanging out past the edge of the case the 18650 fits.

      EDIT: Possibility of the 18650's higher voltage may damage the device although mine's been ok so far. Try this at your own risk.

    This is a great little tool and cheap too! I've got one and wondered how I ever lived without one!

    • +3

      Easy… The thing you're using stops running, you take out the old batteries, you put new ones in, and throw the old ones away… and so the cycle continues!

      • Like a lot of households, I keep spare batteries in a drawer for just such occasions. Trouble is some go flat faster than others. Most of my devices take 2 to 4 batteries, but will run on less for a short time.

        So I stick 4 batteries in a device. It goes flat a few days/weeks later. Which ones are still ok? Which ones are dead?

        With the cost of batteries, it happens enough to have made a $3 tester an easy investment.

          Can I suggest one of OzBargains most favourite brand names… ENELOOP!!! ;)

  • I have 3 of these floating around at work for testing batteries for my Radio Mics. They all read fairly close to each other ie: 1.53V in one will be 1.51 in another (Very close to what my Fluke DMM read). I haven't tried to see if they fit a 18650 but will try to remember to report back. They do 9v Batteries as well so it is a possible length issue not a voltage issue. Very handy to have around.

    • Please do check whether 18650's fit, it'd be much appreciated.

      Do you know of any other devices like this that work well for testing 18650's?

    • all read fairly close to each other ie: 1.53V in one will be 1.51 in another (Very close to what my Fluke DMM read).

      Hmm. So that means this doesn't test the battery under load?

      • It does test with a significant load, and the initial voltage reading drops quickly to reflect that…

        Fappo, tester will not physically accommodate even an unprotected 18650 battery, and is not designed to test lithiums of any sort. Separate wiring and (SMD) resistance values applied to the 9 volt input.

        Review on a site somewhere mentioned a meter working fine until a 3 volt lithium button cell was tested in the main slide - then, kaput.

        • +1

          I've modded mine to fit 18650 cells and so far it hasn't gone kaput. Naturally you don't leave a cell in there for any extended time so maybe short test periods are ok, or it may blow the next time I try it.

          Just out of interest I've tested the current draw of this device. A new AA alkaline has around a 50mA load and a near full charge 18650 (around 4.15v) around 150mA. The 9v side input draws about 8mA from a new 9v battery.

        • It does test with a significant load, and the initial voltage reading drops quickly to reflect that…

          doogiechap says it's very close to his DMM, which would mean no load or a very light load. Does yours work differently?

          Review on a site somewhere mentioned a meter working fine until a 3 volt lithium button cell was tested in the main slide - then, kaput.

          One of the photos on the site shows a 14500 being tested. Hmm… misleading ad?

          Ahh, good to know, thanks. I prefer my all-sun BT21 tester with selectable load but it's quite hard to find now.

        • @eug: Concurring with your doogiechap-confusion. Mine definitely tests with a significant load.

          I've had my 'BT-168D' for about 18 months - identical to the unit in the T-Mart photo, but purchased from another seller.

          Given reports from sellers of angry lithium-testing buyers, manufacturer/manufacturers may have tweaked the internals so as to display the higher voltage.
          Cheap enough to replace without any mourning, for anybody who wants to risk it.

  • The youtube review is not in English @_@

    • Turn on translation

  • It looks no longer available. Checkout page says coupon use is restricted.

    What a waste of time, went through the checkout process only to get this message at the final page

    "Oops, you miss the chance; the code is use up."

    Right……

    • same. code no longer works

    • The coupon code is used up now. Pity that you come too late.

        That's usually better than coming too early, right?

        • haha

  • Leftdrop - what did you guys have, like, 10 uses of this code? Emptying my basket now…

    • Hi, the coupon code is 200 uses.

      • oh well. no stuff I probably didn't need anyway for me.
