Testing double-A batteries: dollar stores vs. major brands (Marketplace)

[@viviancrompton1920]

Disposable batteries should be required by law to state how much usable energy they contain - for example how many watt hours (or how many milliwatt hours) they can deliver until their voltage drops below some usable threshold. Everything else has to state exactly how much product you are getting for your money - if you buy a chocolate bar, loaf of bread, petrol or can of beans, it always says how much weight or volume of product there is. Even rechargeable batteries usually say how much they can store. Why don't single use batteries have this packaging requirement? Even better would be if they stated both watt hours(ie. energy) and the rate at which they can deliver that (ie. power)

[@lumberjackdreamer6267]

The usual standard is to rate the capacity at “1C”. For example if a battery is 2800 mAh, that’s 2800 mA for 1 hour. That’s 1C If you discharge that same battery at 2C, you would draw 5600 mA, and it will last less than 30 minutes. If you discharge it at 0.5C, you draw 1400 mA and it will last a little more than 2 hours.

[@zybch]

Problem is that the vast majority of rechargables only rate at 1.2V (not sure of enerloop) but devices are designed around 1.5V. Not good on the device, not good on the batteries.

[@Xenon255]

@@zybch 1.2V is the nominal/average voltage of NiMH battery cells. They range from 1.45V freshly charged to 0.9V at the end of charge. Typically they hover over 1.25V to 1.3V for the majority of its discharge. Also many devices (unfortunately not all) tend to tolerate a wide voltage range since even alkaline cells will drop in voltage as they're used up.

[@Jackson-T23]

I'm assuming you are talking about NiMH and not Lithium. I bought a bunch years ago, but recently started switching back to alkaline for many applications. The rechargeables aren't bad, but far from perfect. First is the upfront cost. Second their voltage (as previously mentioned) is lower. Third - It's almost impossible to find good C or D cell NiMH.....and those AA conversion shells just don't cut it. Four- many brands the batteries are physically larger.....making it a problem when they get stuck inside something like a pen flashlight. Five- the biggest drawback is their short shelf life. You have to top them off every 6 months or so because they lose power sitting on the shelf. I have a ton of battery powered devices and don't have time to recharge 3 or 4 dozen batteries twice a year.

[@ColinWatters]

For decades manufacturers have resisted calls for the capacity to be printed on the batteries. They say its not possible because it depends on the current draw. That's true but it also applies to rechargeable cells and they can mark them.

[@GillhamFamilyShenanigans]

What Duracell and Energizer missed was that they can come down on their price and still make a profit by being competitive with the cheaper brands, especially now that people know that the cheaper brands are just as good. And the 2 that leaked were name brands. The cheaper ones didn’t leak

[@TheEudaemonicPlague]

They didn't miss a thing, goofball, their profits are very high--in what way do you think reducing their profits would benefit them?...because people like something they can depend on, and no-name batteries are always going to be a gamble, no matter what the test today says. Yeah, so the abuse they put the batteries through caused a couple to leak...but the test is not real-world results, but lab results, and there's often a great difference between the two.

[@weirdplasticlabs]

@0:34 does “sloppy top” mean something different in Canada than it does in the states? I don’t think that phrase means what he thinks it means

[@maxheadrom3088]

The bounce test works more or less and that voltmeter should not be used to test the battery - and here's why: digital voltmeters have what is called high impedance inputs. High impedance inputs behave like open circuits so they'll show the voltage of the chemical setup without considering the internal resistance. The best way to test that is to put some resistor (50 ohms, perhaps) between the battery's terminals and then measure the voltage - that's why the battery tester is the best device for that. What is the "voltage of the chemical setup"? If we go back a few centuries to Italy, Alessandro Volta (the guy that lends his name to Voltage) built the first galvanic battery. That was zinc and copper places with salt water soaked cloth between them. That battery has 1.10V because that's the the difference between the two metals "will to get or give electrons". Copper wants to get electrons at +0.34V while zincs wants to give electrons at -0.76V. (it might be the opposite but ... that's the idea: it's a property of the metals and if I use a device that draws no current from the battery I'll read 1.10V regardless of how well the chemical reactions are happening.)

No, the “bouncy test” does work, it’s just you don’t understand what the expectation is.

Not only that but _significantly_ used. I think that 1.3v is a cut off for a lot of electronic devices to function, so it's misleading to say that the battery is still good. It's lost most of it's energy, and will only run specific devices, likely a flash light or other primitive device.

"Best" depends on your metric. The metric generally depends on your use case. For example, you might prefer a battery with more total power for your smoke detector, even though you are paying more for the power you're getting. You would want it to last until your next scheduled battery change.

[@SmallSpoonBrigade]

For the most part, no, a battery is a battery. The only measure that typically matters is the number of mAh that are in the battery. A 9v battery is a 9v battery, as long as the mAh is the same, you shouldn't see any meaningful difference. There is some variation in how well they do with cold and how flat their discharge curve is, but chances are that any differences that you're seeing are the result of the placebo effect. If you want to see a significant difference, you have to jump to something like NiCad or NiMH which do have significantly different characteristics.

That expiration date is typically ten years when new. Further, while remotes and clocks are low-drain devices, a flashlight is definitely NOT.

The eco fee is yet another useless cash grab... As for alkalines, Duracells are absolutely the worst in terms of leaking - they are simply awful. Energizer ultimate lithiums are outstanding in hi drain devices and outperform alkalines in cold temperatures as well, won't leak BUT are expensive. Rechargeable NIMH are the absolute best value for your dollar as they can be recharged hundred or thousands of times. They will work as well as alkalines - and even better in some devices, such as cameras as they maintain a more constant voltage. They do start at a lower voltage than alkalines (roughly 1.3 V vs 1.5 in alkalines), but stay in the 1.2V range for most of the time, while alkalines drop quickly from 1.5V to 1V...

An executive picked up the line and told me they will send a local repair company and they will honor my warranty. When I received the repair invoice from the repair company, it said the repairs cost LG $1800, which is the same price as the fridge brand new.

[@tookitogo]

Bear in mind that a NiCd charger will overcharge NiMH cells, reducing their overall lifespan. A good modern NiMH charger will get the most out of your batteries. (Proper NiCd and NiMH charging work on the same principle: once the battery is full, the excess energy being pumped in turns to heat and the battery heats up, which in turn causes the voltage to drop. So the charger looks for the peak voltage, and once it starts to go down, it ends. However, in NiCd, the voltage drop is much larger than in NiMH. By the time a NiMH cell’s voltage drops to the point a NiCd charger can detect it, the battery has been significantly overcharged. Many old “intelligent” chargers actually weren’t that smart. What you want is a modern one with “-dV/dT” charging.)

In most flashlights however (for example), the extra performance you'll get is generally not worth the price difference I find (especially is you find cheap alkalines, which is often the case).

Great work on doing this test, but at 2:37 you reinforce the important myth that simply measuring the voltage on a battery tells you if it is still good. You need to place some load on the battery, and then see what the voltage reads. The comparatively primitive looking 'battery tester' you use a few seconds earlier will almost certainly be reading the voltage under load, meaning it gives a more accurate result than the digital voltmeter. Some voltmeters have a battery test setting, but many don't. To test this, measure the voltage across your car battery with the ignition off. Now look at the voltage when the engine starter is turning. With a good battery it will drop a volt or two. With a dud battery it may drop to 5V or less, despite a good and a bad battery reading over 12V without load (I forget the exact values you want to see in a car battery).

[@dafly46543]

Yea, but we are talking low capacity vs high capacity batteries and different battery technology. Yes a car battery you have to put a load on it to test it. I don't know if the same is true for small batteries like this. Besides, who wants to drain the capacity out of such a small battery just to test it. That's kind of silly. The voltage test on these is good enough. Heck, who even test batteries anymore. Unless a device doesn't work with new batteries, is wasting your time worth it? Heck, any weak batteries out of some high drain items, I would sometimes finish up in a remote and use fresh batteries in the device that benefit from it.

[@gnuthad]

@@dafly46543 The principle is still the same between large batteries and small batteries. The only difference is the load under which the voltage should be tested. A digital multimeter will be putting on an absolutely tiny load which is effectively no load at all. The battery tester is putting on a more typical load (although still small by many current equipment needs) and so gives a more accurate result.

[@dafly46543]

​@@gnuthad I'm referring to the battery type as to whether a load needs to be placed on the battery for testing. Car batteries are generally lead acid batteries. You also need to have a charged battery to load test it. You do not or should not charge disposable batteries. I have never had issues using a voltage meter when testing disposable batteries. It is more than suitable for someone to tell if the battery is good or not. These batteries are very low capacity to start with. So why would you use a portion of it just to test it? Again if you power on a device and it doesn't work, then by all means check its voltage if you wish. But why even go through that. Toss in a set of new batteries and see if it works with fresh batteries. If it don't, try a other set of batteries as maybe someone placed old batteries with fresh batteries. I personally don't mix them. As you should never mix fresh with used anyways. Disposables are cheap. But again, as far as load testing, why? A car battery makes sense as your plates build up sulfate. But again, if the battery is not charged, you can't do a proper load test. If you don't get a proper reading after charging for so long, consider the battery junk. This is the reason we are load testing car batteries, due to sulfarication that happens over time. I guess instead of saying to use a digital voltmeter, I should have said voltmeter, or more preferably an analog volt meter as this was what was originally used to test disposable batteries with and uses more current to get your reading. But I would not call this load testing. You will see the meter drop if the battery is bad. If it is good, the needle will shoot up instantly and hold. I use to test disposable batteries all the time when I was a kid as this was installed into me from my cheap grandfather. I also tested many automotive batteries as I was a licensed mechanic.

[@gnuthad]

@@dafly46543 The load you use to test a car battery is much higher than the load you use to test a AA cell which is much higher than the load you use to test a tiny button cell. The load varies depending on the claimed capacity and cell chemistry. The principle of load testing is, however, the same. An analogue multimeter set to 2V or so is ideal for testing these disposable cells because the load is about 20kΩ. The digital multimeter has a typical load of 10MΩ. The load you need to test a 12V car battery is fractions of an ohm.

[@tookitogo]

@@dafly46543 Yes, you absolutely have to measure small batteries with a load for the result to be meaningful. The open-circuit voltage of a battery can be fairly high, but the voltage plummets under load. That’s what battery testers do. Of course, different batteries behave differently under different types of loads, so it’s always going to be a generalization of the battery state of charge. However, you’re confusing car battery load testing (i.e. determining the state of health of a rechargeable battery by seeing how much current it can push) and rechargeable battery capacity testing (determining how much energy the battery is capable of holding) with state-of-charge testing, which is what the segment of the video was about: determining how much energy is still left in the cell _right now._ The point is that a battery’s open circuit voltage is not in any way a reliable indicator of state of charge. This is true for every type of battery, whether primary (disposable) or secondary (rechargeable). In fact, for some battery types, the voltage tells you almost nothing, because the voltage remains constant right until the end, where it just suddenly plummets. For standard AA alkaline and carbon zinc, voltage is a decent indicator, but they must be tested with a load. You don’t have to discharge the battery to do that. You just attach the load, measure the voltage, and then disconnect the load.

It’s much cheaper to produce products in countries or facilities that don’t follow best practices when it comes to dealing with chemicals and safe work environments for their employees. The price of more responsible production COULD be built into the price of the bigger companies. Cheaper brands often cost cut when it comes to environmental considerations in their supply chains and processes.

Sometimes I forget other people don't know things I experimented with as a child. I take for granted this kind of info is not well known. Well done educating others.

[@Robbie-mw5uu]

Um yes other people have different experiences than you...? It's not that difficult of a concept.

Good to know! appreciate CBC for doing the comparison, good to watch a marketplace where people's lives aren't being ruined by scammer, but please continue to do those shows, I show them to my mom so that she becomes more aware, better to hear from victims than me, paints a clearer image.

[@Ben10Arg]

actually the CBC is lying to you and the public. The only reason this video was created was to fire shots at American owned Duracell and Energizer because the recycling of the batteries will no longer be happening in Canada but is now forwarded to U.S companies. Think about it, the video was originally about the quality of the batteries then suddenly they diverted to talking about how Canadians are being targeted and ripped off.

I think this was a great and very informative test, thank you! I’m pretty sure I won’t be buying those EXPENSIVE name brands again. Have you done any testing for the other size batteries? C, D etc? Thanks again

[@itsnotme07]

Good info on the pricing vs "dollar" stores, which most of them aren't a dollar anymore. LOL I already knew the alkaline part, but wow on some of those carbon zinc batteries capacities.

[@4seeableTV]

It makes you wonder why anybody would buy them. Sure they're cheaper, but probably end up costing just as much as alkaline because you need to buy so many of them to equal the same capacity.

Blame Jerome Powell and Donald Trump who hired him as well as the guy who destroyed the business cycle Ben Bernanke. All of these people should be doing life terms in prison.

[@baneverything5580]

@@parkerbohnn Trump is involved in the alkaline battery business? WOW! You leftists are far beyond deranged...

[@IAMSatisfied]

It's a sad state of affairs when this stuff isn't taught by parents or the schools, but you have to rely on a tv news show to get a clue about this.

[@kylereese4822]

Yea I learnt about this stuff when I was about 7-8 years old my granddad taught me :):)

[@truthseeker2797]

Yes, but do cheaper batteries have a higher probability of corrosion or leakage?

[@westabsupplyebay4093]

I've stuck with AC Delco brand for years up until recently where I can't find them as easily.

[@violinmke]

Amazon ca has them
