This is the type of multimeter that you find at Harbor Freight, Walmart, or Target. It's fine for batteries but not much more.
I included some links so you can check out the prices and see a bit more about them. I would recommend spending at least $50 if you think you will be using it often and doing more than test batteries. The better meters are safer and have resistance when testing batteries (more accurate) also they will be auto-ranging. That means you do not need to turn the dial all the time.
The one I'm using in the video is a Cen-Tech, P35761
The black one you saw is an ESun DT830

Just got this for free at harbor freight. I got this specifically for testing a drawer full of batteries to see which ones are good and which ones aren't. Thanks for explaining the basics on how to do that. I appreciate it!

@Milesco 3 года назад

But without putting a load on the batteries, you can't really see whether they're any good or not. You need to put a fairly heavy load on a battery to get an accurate reading of its condition. I use a 1-ohm resistor in parallel with the meter in order to draw enough current out of the battery to properly and accurately test its condition. If you don't do that, the battey will give you a falsely high voltage reading and it will look "good" even when it isn't.

@sarsaparillasunset3873 2 года назад

if you don't have a resistor, load your batteries into a TV remote control, that oughta put some load on it. Then measure the voltage on the battery terminals while they're in the remote control.

if my multimeter got the "9v batt" does that automatically mean it will put a load? thanks

Do you know what the cutoff voltage is for the battery? At what point do you replace the 9v battery?

@adebcfc885 8 лет назад

Thanks Adam, was totally confused with all the settings on mine, now I know, just keep it on 20 (DCV) :-)

@dougier8093 9 лет назад

Use a resister around 100 Ohms to draw the battery you'll get a better reading. And thanks for a very clear, good instructional video

@Milesco 3 года назад

Indeed, except that I would go further and say that even 100 ohms is too high (far too high, to be honest) to really test any battery. It's just nowhere near enough of a load to properly test a battery. I would use 1 or 2 ohms for a 1.5-volt cell and around 5 ohms for a 9-volt battery. That way, you can get a good idea of the battery's internal resistance (which is really what you're measuring when you test a battery). A 100-ohm resistor is so much higher than the battery's own internal resistance that it "swamps" (overwhelms) it and masks the battery's own condition and capabilities.

@bl8rg8r 7 лет назад

Bad Bad Advice. One should know how to use a multimeter before "teaching" someone else how to use one. the "audio" function he is referring to on the better meter is a diode tester. forward and reverse voltages are not gonna be the same due to circuit protections in most good batteries. One should only test batteries with a battery tester or a meter with a battery testing function. Read your manual for you meter to understand how it works and how to get good readings from it.

@ray0gun 7 лет назад

The other Cen-tech model 90899 has a 9V(25mA) on the dial for this very purpose. It puts a load of 370 mΩ and it should read 25mA.

@nhlakancube6614 7 месяцев назад

Your video is clear and simple, thank you for that.. was testing the 12v car battery 👌🏽👌🏽

@somesharunvn 6 лет назад

Without Load its impossible to confirm whether the battery is good or not..I would say reading closer to 1.4V on a common multimeter can be considered as a good battery. I had a bad battery which is not functional anymore read the voltage as 1.26V in multimeter, but when i applied a 100mA load the voltage dropped to 1.01V which is below the nominal threshold voltage of 1.1V. As a result the battery was not operational!

@neilwilliams5814 8 лет назад

batteries have an internal resistance. You need at least a 100 ohm resister to get the ACTUAL voltage reading.

@satan4635 7 лет назад

This comment is actually more helpful than the video

@eolhcytoos 7 лет назад

Quite correct. A nonsense video and no use whatsoever to indicate the state of a battery. You need a load across the terminals to get an accurate voltage reading.

@bobone866 7 лет назад

Neil Williams so How do i do that? i want to test some cr123 batteries. i have the AA and AAA setting but ithink the setting won't work for these batteries

@pershop4950 7 лет назад

He mentions the other multimeter that should give the load test at around 2 mins. However, he didn't open the package to use it to show. So take it with a grain of salt...the video shows how to get the Voltage reading, which some people may not have know. It also mentions the load test, which someone may or may not have caught.

@robertrose3068 6 лет назад

He said in the video to get a better multi-meter to put load on it if people would listen. Pay attention.

internal resistance increases as you reach the end of the battery life. If you directly read the voltage without a load you may have a normal voltage which would fail in a few seconds when connected on load.

@sirjcurry2182 7 лет назад

Great video. Thanks.

@G56AG 9 лет назад

This is a classic example of a crappy multimeter, your meter showed 1.8 volts for a AAA battery, there is NO WAY that AAA is putting out 1.8 volts DC, that meter is grossly inaccurate, which is what I found when I got one of those Cen Tech meters, it was so inaccurate it was almost useless. Spend a little bit more money and get a better meter. Battery testing without a load doesn't tell you much, some batteries will test OK with no load, but bad with a load, so add a little resistor (about 100 ohms) or get that meter with a dedicated battery tester built in.

@timothy790110 6 лет назад

@danhard8440 4 года назад

yes a 1.5 volt battery can and will be over 1.5V that is how they get the extended life just like all 18650 are rated 3.7 but there range is usually 2.5 top out at 4.25V

Those cheap multimeters from Harbor Freight can sometimes be way off, they often give those away, at least they used to, I had one that was so far off on low voltage DC that I spent a lot of time trying to find a problem, and in the end the problem was with the meter.

@JuQmadrid 8 лет назад

So does de voltage measures the juice left in the batery?

@Milesco 3 года назад

Nope. At least, not the way this guy does it. In order to properly test a battery, you need to put a load on it. That means putting a resistor in parallel with the meter so that it draws a fair amount of current out of the battery. Only then will the voltage reading tell you the true condition of the battery. In order to draw an adequate amount of current out of the battery so you can get a reliable measurement, I would recommend a fairly low resistance e.g., about 1 or 2 ohms for a 1.5-volt cell and around 5 ohms for a 9-volt battery. Be sure to connect the resistor _across_ the leads of the meter (not in series with them.)

@lowelltilley8267 5 лет назад

Batteries have an internal resistance which goes up as the battery dies. Just testing with a voltmeter with no load doesn't tell what the internal resistance is which determines if it is good or bad. I used to use my tongue to test batteries until I heard people have been killed that way.

@h8GW Год назад

Your multimeter seems to be measuring a lower voltage when your polarity is reversed. Even my cheapest Harbor Freight one works more consistently than that.

@sas9858 9 лет назад

Thank you for your video. My ? is what is the lowest V for a battery to still be useful. I have AA that are 1.45 (used) and 1.51 (new). Both are RAYOVAC Alkaline, Expiration date 12-2018.

@AdamDIY 9 лет назад

If you are using them for a TV remote, you can get away with a voltage as low as 1 or so. But for me if the batteries get to about 1.2 or lower, I usually throw them out. Thats just me.

You need to place a 100 Ohm resistor across the battery to give it some load. No-Load readings can be misleading.

A better instructional video would have been 15 seconds long, and would have shown using only the better multimeter in 9v mode. The audio commentary would be "Use a multimeter with a built-in load like this one, to test batteries correctly under load, otherwise you'll only get the voltage".

@jeffreydeutsch7336 6 лет назад

The meter you are using has a load test position for 1.5 and 9 volt batteries. Why would you use the no load voltage ranges? The meter has often been compared to meters costing far more. Accuracy is not the problem. It is the fall apart leads and flimsy construction. You also got ripped off. You have a Harbor Freight meter. They often give them away with any purchase. When they are not being given away they are about six bucks. People put their freebies on ebay and sell them for 10 bucks.

Decide. Is the yellow meter reading right? No. Why? You need a load on the battery. Then you show the other with the battery tester, which is the right way. BTW, it does not give "true voltage", it goes the current in mA. You're not helping anyone with bad info..

@myradioon 5 лет назад

You skipped an important part in explaining which two holes (out of three) you have your leads hooked up to on your meter and why? If you're measuring volts in the first example -why is your red lead hooked up to the 10A dc? hole (which I had to zoom in to see and also says Voma whatever that means). This is the kind of stuff that is confusing about multi meters. Assuming it's common knowledge when doing a video like this is whatever.
