I find that when testing batteries with a DVM sometimes they read good but they don't function, probably because the internal resistance has gone high. Can anyone recommend a tester that loads them during test, preferably one you actually have used. I could use a resistor in parallel with the DVM but it would be nice to have a tester so that I don't have to do that.

I have like that, it`s very useful
my Tester is a 07913, maybe out of production now, but a near relative in function

greetings

I spent some time watching eBay and scored a nice Simpson 379 battery tester. It's compact and cute, and quite useful:

RCA had a similar meter, the WV-37:

Simpson had an add-a-tester for the 260 that was a battery tester.

Radio-Shack sold one as a kit, I still use mine, despite the "cheesy" jacks... The jacks selected the voltage, a range switch selected the load. The meter, simply read GOOD-?-BAD...

It is best to place a resistive load appropriate for the cell or battery being tested.

When I was building "B" batteries from carbon/zinc "D" cells I would pre-test each cell at 125ma. I sent marginal cells to the clock if the voltage appeared too low. Result was a "B" battery that when exhausted, failed across all cells not just a few "weak" ones...

I have one of these I bought years ago and I use it often.

I like the digital display and it's easy to use.

If you want a really high quality battery tester, I recommend the Simpson 379. I have a few, and I love it.

There's lots of useful battery testers out there; they usually have some sort of loading resistor to test the battery under a medium to high load. I use a Triplett 1947 model that's about the size of the Simpson 379 photo(above). Its Good-?-Bad scale on the Triplett is neat, as they used only two colors of ink to make the three colors; the middle band is "benday"(dots and cross-hatches of the two ink colors spaced to create the third color). benday was popular in comic books and modern art. Some models capacitor esr testers can be used to measure battery cell resistance, which often rises as the battery goes bad...was discussed previously on ARF.

Thanks for the great advice guys, I'll keep my eye out for a vintage Simpson or Triplett. In the mean time I will get the BT-168D digital one.

Can you post a pic of it? I've never seen one.

I have one also; easy to use and see the reading, and seems to be relatively accurate.

I bought that digital tester and it lasted one week.

I still use my RS Micronta. 22-100A

I like my RCA WV-37A. It tests batteries up to 90 volts, and has a beautiful hammertone finish.

I thought I'd post some pictures of the Simpson Model 379 Battery Tester to this thread, and also mention an alternative: use a resistance substitution box in parallel with your DMM.

I had spotted a Simpson 379 at NEARfest a few years back and regretted not picking it up then. I spent some time searching for one on eBay and finally found a nice specimen, although at a steep price.

Image

But it did come with the original box ...

Image

... and test leads.

Image

I had to rebuild them as the old rubber insulation had hardened and cracked.

The Simpson260.com web-site has a scan of the manual.

RCA also made a similar meter, the WV-37.

Jeremy Schotter has a scanned copy of the manual for the WV-37A on his RadioRestorer.com web-site. One interesting feature of the WV-37 is that the range switch has blank positions where you can customize the imposed load and the voltage range.

However, you can also make a quite effective battery tester if you are armed with the battery specifications, a resistance substitution box, and a DMM.

Image

Just connect the resistance substitution box in parallel with the DMM, set the resistance value to give the current draw that you want to use when testing the battery, ...

Image

... measure the battery terminal voltage under load, and compare it to the manufacturers data.

Here are some more views of the Simpson 379 Battery Meter.

I have one of the free Harbor Freight meters that has the test functions that you are describing. Mine is a model 92020. The instructions from the manual are below. I use mine often and like it.

Battery Charge Measurement
Test the amount of charge left in batteries. NOTE: This setting is for testing the charge of small 9V or 1.5V batteries only. Never use this setting to test automotive or lead-acid batteries. The high current could cause damage to the meter and/or cause severe personal injury. Use the appropriate DC Voltage setting to test the open current voltage of such batteries instead.

1. Turn the Range Selector Switch to the Battery position.

2. Plug the red Test Lead into the VΩmA (Center) Jack. Plug the black test lead into the Com (Bottom) Jack. Switch the Multimeter ON.

3. Connect the red probe to the positive terminal of the battery and the black to the negative terminal.

4. The battery amperage under a load of 370 mΩ will be displayed to a resolution of .1mA.

5. Normal amperage: For a standard 9V (6LR61) battery = 25 mA
For a 1.5 V “AA” (LR6) battery = 4 mA
