I am tired of pulling out the multimeter to test my Eneloops. This volt meter is an easy way to solve that problem.

I have been trying to get a deal for this for some time. I finally managed to get a deal on it today.

Thanks Oppick for the codes.

Description:

BT-168D Universal AA/AAA/C/D/9V/1.5V LCD Display Battery Tester Button Cell Volt Checker

Things seem to be running a bit slow? Still running slow after you replace the batteries?
Why waste time inserting and removing battery after battery when you can just test it.
Maybe it's not your batteries at all. With this tester, you can make sure of that.

Test the voltage of AA, AAA, C, D, 9V, and even mini cell batteries. Voltage range on the back of the tester will help you determine the quality range of Good, Low Power, or Replace.

    I had this from last year's deal, similar price, but the quality is very bad, only last about 6 month with 7-8 times use.

      How did it fail - did it fall apart, or just stop working?

        I got the analog version but believe the construction would be the same. The red terminal is linked with a piece of wire and with the sliding action it breaks every often I have to pull it apart and solder the wire all the time. At the end I gave up and bought this.

    Get a tester with actual load built in so you can see true condition of batteries. A cheap volt meter like this will only frustrate you and not tell you much about them at all.

    • OzBragain on 12/06/2017 - 20:44

      Any suggestions?

        These are fine for checking voltage of batteries. Voltage is nearly always a good indication of whether they're full, half-full or need charging. In 99.9% of cases, it's all you need. Cheapest ebay price is a bit above this one.

          'These are fine for checking voltage of batteries.'

          I agree with this 100%. I have owned two of these in the last 3 years, and used both well over 100 times. The 'build' of this product does feel kind of flimsy cheap, but that is no doubt because it IS in fact dirt cheap. The important thing is that it works, and it works well. It seems to apply a very small load to the battery wile testing it, such that an 'almost dead' battery will decrease in charge on the LCD screen as you are testing it/before your very eyes. I'm told this is a good thing, re a reliable charge test.

          In short, I have owned two of these units (first one was destroyed by a young child/it did not 'fail' in the course of normal use), and both were remarkably durable/useful/accurate. I am still using the second one often, which is now well over a year old.

          For educational purposes, please check out the following short video:

          https://www.youtube.com/watch?v=HcikzMG7mMU

          Skip to about 3min30sec in for the nitty gritty, otherwise listen to the whole lot to get a better understanding on what I'm talking about.

          In a nutshell, voltage is a POOR way of determining battery condition. The video quickly demonstrates why.

          By all means buy these crappy little voltage testers… but they won't tell you much at all.

          Just sayin.

        • lomie on 13/06/2017 - 11:08

          @UFO: How much "actual" load is required for a battery tester?

        • UFO on 13/06/2017 - 11:36
          +1

          @amts:

          When I was first bought my Eneloops and Lacrosse charger, I really wanted to make sure I was looking after my batteries and wanted to know their real condition during use.

          About a year ago I found this very useful thread, which explains Ohm's Law nice and simple like :).

          http://www.instructables.com/id/Add-Battery-Test-to-a-Multim…

          Have a quick read. It basically explains why 360 ohms is an ideal load to place on smaller 1.5v batteries.

          Some multimeters have the setting readily available, but if you like it's easily made yourself for a few cents!

          You need to load up a battery when testing folks. Reading the voltage only (like all of these cheapy $3 ebay meters) is next to useless. An almost dead battery can still give a 'fake' high reading, achieving only frustration on your part when you try and use it. In that case, you may as well not test them at all and still get the same frustration :).

        • lomie on 13/06/2017 - 12:11

          @UFO: So a 4ohm load is not enough for 1.5V?

          @UFO:

          By all means buy these crappy little voltage testers… but they won't tell you much at all.

          There is a (higher value) resistor inside this unit.

          I can store this unit in the same compartment box I store my eneloops. It's convenient. It works for indicating whether your batteries could use a top-up. Only in special cases do you need anything more, in my opinion. So the unit performs its function well.

          @GnarlyKnuckles:
          It does indeed place a load on the battery. Easy to verify by opening it up. I honestly don't know what the complaints are about.

          @UFO:

          '… but they won't tell you much at all.'

          You are over-generalising/assuming that the only purpose peeps would have for these is determining battery 'condition'.

          If you've accidentally mixed up some batteries you recharged with some you haven't, this device will help you out instantly/without plugging anything in.

          If you want to know if a toy/torch/etc. has suddenly stopped working simply because the battery/ies are dead, this device will tell you that.

          If you want to know whether a 'random' non-rechargeable you find around the place is worth chucking into your cheap wireless mouse to keep it going for a month or three, this device will tell you that.

          Etc.

        http://www.ebay.com.au/itm/LCD-Digital-Multimeter-handheld-A…

        Just a quick ebay search. Might be able to get cheaper.
        Magnified view of the dial on the meter shows a 1.5v setting.
        Any meter with that on it would do the trick :).

          I have a Fluke Multimeter and it is a hassle to get it out of the tool box to simply test the batteries in the kid's toy.

          Based on reviews on some forums there is a load placed when using this cheapie meter.

  • cheepwun on 12/06/2017 - 20:42

    These are useful. No two units will be exactly alike though, but good enough for a quick check of voltage to gauge charge. The unit doesn't have its own power supply, so keep tests brief. Testing rechargeables, make allowance for the lower nominal voltage compared to prehistoric disposables.

  • Wiser on 12/06/2017 - 21:22

    Works well and good price.

    • cheepwun on 13/06/2017 - 01:43

      Those are about half that price on ebay. Lots of those listings with the analogue meter instead of the LCD (with false ebay ad titles denoting "LCD"). I prefer the digital LCD. Looks like ARLEC just put their name on the same unit as the ebay ones.

      • lomie on 13/06/2017 - 07:45

        Depends if you want it straight away or wait for shipping from China.

        • cheepwun on 13/06/2017 - 13:41

          As always! I'd rather get 2 for the price of 1, personally.

  • cheaparse on 13/06/2017 - 08:38

    Can this tester be used to test 18650 batteries?

    • trev likes bargains on 13/06/2017 - 09:05

      It doesn't fit. People have modified these to make them fit and then it works.

      I think you can only test them one at a time.

  • ShipShapeRC on 13/06/2017 - 14:10

    Forget the BT-168D (digital) get the BT-168 analogue version as it has a bit more load when it tests, so it give a better indication for all reasons spoken about above. Plus it's cheaper too!

    • UFO on 13/06/2017 - 14:30

      Actually, I believe you are quite correct!

      With an analog version, the current must physically move the needle… so there must be some resistance to that.
      With a digital one, there would be less drain simply powering the LED.

      It would be very interesting to measure the difference between the two.
      Any rockerfella's here want to buy them both and test? :)

      • ShipShapeRC on 13/06/2017 - 14:40

        I do have both. Not sure of the testing method though. Unless tie it to it and wait for the sharp drop after nominal capacity is met.

        • UFO on 13/06/2017 - 16:00

          At a guess (I'm not a pro at this :)), maybe make a simple circuit with a couple of loose wires?

          1.5v battery > one end of meter being tested > multimeter > and then back to other end of 1.5v battery.

          The entire meter being tested would be a 'resister' in the circuit being tested.
          Take the measurement and then swap the meter over to the other type.
          It would be interesting to see the difference!
          My bet is the analog would be of higher resistance, unless the digital one has extra resistors to match the analog one… which I doubt.

    • [Deactivated] on 15/06/2017 - 17:37

      I used to think that, until I run into issues where battery give 1.3 volt and still can't power the remote. You need to have a resistor in series to perform a load test
