@100vg Год назад

He may have blown up the Energizer faster than the Duracell, but, really, who's going to do that and how could that ever happen under normal use? I switched to Energizer cells for everything because of your testing. I used to use Duracell exclusively because Duracell CLAIMS they last longer than all others, but they always make that nasty white corrosion mess which turns terminals and wiring rivets green when left in any device I've ever used if the device is not used for a long time. As I recall, your testing (and reviews all over RU-vid) show that Energizer cells do not do that. Because of my extensive Duracell corrosion issues for years, I started taking all Alkaline cells out of all devices and storing them in tiny ziplock bags (so the terminals cannot touch) along with the device in a larger ziplock to prevent that corrosive buildup and this also prevents the devices from discharging the cells. It's odd that the Duracells don't do this when stored out of a device. I came to the conclusion that something about the pressure from negative terminal contact spring is what's causing it. I can't say if Energizer cells would do this under the spring pressure or not because I still take them out, but I have a wireless security system with door/window open, motion, and glassbreak detectors that use Alkaline cells, so I may find out soon enough. Thank you for everything you do for us, Todd!

My Maglite flashlights have SO many internal battle scars, but usually I can get the batteries out and clean them up with Vinegar. A few years back I decided it would never happen again so I've been gradually switching to lithium rechargeable lights. All remaining Maglites get a battery change every NYE regardless if they need it or not.

@shaun5552 2 года назад

Practical experience is alkaline batteries leak when they're partially discharged and not being subjected to a decent rate of regular discharge. Eg a flashlight that's been used then left switched off is partial discharge with the light followed by weeks or months just sitting there with very slow self-discharge only. Or a TV remote that simply never applies a significant load to the battery even in use. Both will cause leakage whereas regular use, for example if the flashlight were used every day, doesn't leak. Just my practical experience.

@electronicsNmore 2 года назад

Correct. I was only trying to speed up the battery pressurization process. Heat is also a factor. Storing electronics in hotter climates makes them more prone to leaks, based on my experience.

@craignehring 2 года назад

Not so sure this reveals why the copper top batteries leak just sitting in the package. There must be some degradation of the materials due to age. Case in point though, do not leave any battery in a device for an extended period

@electronicsNmore 2 года назад

Agree. My guess would be that the Duracell alkaline battery design is also allowing higher levels of hydrogen gas to form within the battery compared to Energizer. Even if the Duracell has a better seal, if it produces more hydrogen than other alkalines, it will be prone to leaking.

@Homer19521 2 года назад

@electronicsNmore 2 года назад

Glad you liked it Jason! Be sure to share. Thanks

@antibrevity 2 года назад

Thanks again for the tests, but I think that your previous pressure test was more revealing about the battery seals. As you noted, this test depended heavily upon how much pressure the chemistry produced at the resulting power level. It might have been better to have limited the current to a few hundred milliamps, but either way I think this test is interesting, but inconclusive. Higher internal resistance is not a good thing. I have a rule that I buy name-brand rechargeables, generic alkalines, and don't buy heavy duty batteries at any price, ever. Rechargeable cells are worth the brand-name prices, as quality usually improves longevity, which increases the dollar value for cells that should be reused hundreds of times, but tiny differences in alkaline performance are not worth the higher prices of the big brands. This is especially true for the premium tiers of those brands, such as "procell" or "optimum", which should, by rights, include a tube of vaseline in the blister pack. Any company can make a decent alkaline, while rechargeable chemistries seem to require some expertise. Even if you paid $5 per cell for a rechargeable NiMH, it would still less expensive over time than the cheapest heavy duty 100-pack you could find. Just *don't* use rechargeables in smoke alarms and you'll be fine; they work fine in remote controls, thermostats, etc. Rechargeables should account for >90% of your battery usage, yet I still see most families that I know repeatedly buying bulk packs of heavy duty cells and suffering with horrible performance and high waste. Yet, they think that they're saving money :|. Most people should stop worrying about which alkalines leak and start buying Eneloops or Amazon Basics NiMH cells and one or two decent chargers to have in the house and garage. And don't buy the premium or high-capacity versions, either; they won't last as long and are simply more profitable to the brand. If a device needs high capacity, it should be using lithium-ion anyway.

@electronicsNmore 2 года назад

Yes, it is an inconclusive test, but it does show that one has higher internal resistance and one leaks less when ruptured, and tends to be more liquid expelled rather than solids. I have one more video planned on this subject, and it should be highly conclusive. Thanks for watching!

@h8GW Год назад

It's possible many families aren't smart enough to use rechargeable NiMH batteries or they had a bad experience with a brand and wrote them all off forever -because the word "green" makes them gag.- I personally like to lean towards the former 😎

@kellykirk5754 2 года назад

I was at a daycare that had many donations of old battery powered toys. We went through and removed the batteries. Overwhelmingly Duracell had the most failures. Even worse the China brands. Which are much cheaper constructed. I use energizers exclusively now and really have problems. I also had to take care of a gas fireplace it used 4 d cell batteries the owner was getting Duracell batteries and every year they would fail leaking all over the place. These were for using the remote to turn it on. She switched to energizers and hasn’t had a leak in 8 years. There are backup batteries and never dead after a year. To be fair Duracell does say remove batteries when not using. Almost like they know their batteries leak over time.

@David-hm9ic 10 месяцев назад

It's possible that subjecting batteries to higher pressure and overvoltage conditions may be barking up the wrong tree. Seals sometimes depend on some pressure to fully seal. For underwater photography, it's common knowledge that once a diver is in the water, they need to get down below 10' quickly so the O-rings in the camera housing have a little pressure to help them seal. At the surface or just a couple of feet down there isn't enough pressure to assist in sealing the O-rings. I suspect the same thing occurs in batteries. They leak under a low, slow pressure condition rather than a high pressure condition. They seldom bulge under pressure as they likely would under higher pressure for extended periods.

@tedlahm5740 2 года назад

I have no idea what this is suggesting (proving) ? Leakage under extreme adverse condition. Which would not be experienced under normal operation?

@electronicsNmore 2 года назад

This was a viewer requested video. Since both batteries use the same chemistry, by overloading each brand using the same voltage setting, you would think the weaker seal would blow first. This experiment showed that the internal resistance of the battery is also an important factor that would need to be taken into consideration for a test like this. Thanks for watching

@electronicsNmore 2 года назад

@@rydplrs71 Of course the seal wasn't designed for this test. The purpose of the test was to create a certain condition that would increase pressure within the battery causing the seal to rupture. To see which brand can take the abuse better. As for lower IR, according to my tester, the Duracell was higher, and it took longer to rupture. You could see the higher resistance of the battery reduced how much current was flowing. 2.65A compared to 3.05A for Energizer.

@sapelesteve 2 года назад

Interesting test results eNm! Now I am wondering how this would translate to real world applications between those two batteries? 🤔🤔

@Quickened1 2 года назад

What might be interesting, would be to place the batteries in a vacuum chamber with a resistor soldered to the ends of each of them, to simulate a fairly heavy/ continuous load, and see which one leaks first! It's no surprise that overcharging them leads to rupture, but what about over discharging? This kind of relates to your last video as well, and may more closely mimic prolonged self discharge...

@electronicsNmore 2 года назад

Thought of that one. :-) I'm beginning to think that the seal strength isn't the real issue, the real issue is that the Duracell brand must be producing more hydrogen gas during self-discharge and use compared to the Energizer and other brands. When the level gets too high, the seal leaks. One thing I learned after these tests, is that the Duracell leaks out a larger amount, and the material is much thicker compared to the Energizer.

@Quickened1 2 года назад

@@electronicsNmore that's exactly why I think this test would, at least to some extent, confirm whether or not, that is the case! Putting pressure behind the seal only reinforces the seal, but a vacuum, along with steady discharge, might actually allow the seal to leak when the gases build. As the saying goes, great minds think alike! lol...

@jerrygaber6150 2 года назад

That sounds like a much better test to simulate real conditions.

@tarstarkusz 2 года назад

Of course, all the heat is a confounding variable. Another test, but one that will probably take longer is to discharge the battery down pretty far and then hook a very large resistor to it and just let it sit.

@electronicsNmore 2 года назад

Yes. The two brands have different IR. Believe it or not, the Duracell temp after it blew was 110F, the Energizer blew the seal fast and it was cooler.

@100vg 2 года назад

It is my thought that the pressure from the Spring, which is so common in AA and AAA devices, is what causes the corrosion or leaking to start over time, more so in some brands than others. Another RU-vidr tested several alkaline battery brands and found that Energizer leaks/corrodes much less than Duracell, with Energizer the winner overall among those tested, but I can't remember if they were tested under Spring pressure or not. Since Spring pressure is the most common installation configuration, maybe compression is the issue. Maybe also the combination of Spring pressure and discharge level. I do know that Duracell has always made big leaky corrosive messes, so I switched to Energizer on his results, but haven't used them long enough to know if they are really better at this or not. I know that this would be a rather lengthy procedure of testing with maybe each battery or set under the same load and compression and load conditions, but if you're interested, I'll leave the procedure(s) up to you. Maybe a 1KΩ or 10KΩ resistor would do. Something for a relatively slow discharge under a constant set load, continuous or not. You tested Energizer and Duracell here, so those two would be fine, or add others if you like. Thanks I just subscribed.

@Random_4400 2 месяца назад

This test is actually very consistent with my personal experience with both brands, I've had countless energizers leak and ruin my electronics literally almost every time i use them and i find it quite funny just how bad it is, Whereas if you were to ask me i cannot remember when was the last time i had a Duracell leak on me. I definitely have but it's far far far rarer. Duracell is just the more superior alkaline battery in my opinion even though people often criticize them with names like duraleak and such. My experience has been the exact opposite lol. I have stopped buying energizer batteries after this experience and the only thing i buy is their rechargeable NIMH batteries now as they are made in Japan & cheaper than the chinese Duracell counterparts at least in my country. But honestly the way i see it is that single-use batteries just don't make sense to me at all. You pay so much for batteries that you'll very quickly throw out possibly in landfill & it only makes sense to me to use them in very low power devices like clocks and TV remotes or radios. I wouldn't even use them in such devices if the device is valuable to you as you can never predict when they'll leak. One thing is for sure no matter what battery brand you go with there's no guarantee that they won't leak no matter what the manufacturer claims on their packaging. I haven't bought single-use batteries in years. I do have quite a few laying around from devices that come with them included as i usually take them out and replace them with rechargeables. I keep those single-use batteries that came with such devices for other less valuable lower drain electronics. This way i literally have no reason to ever buy alkaline cells even when i do need them simply because of how much i have laying around from devices that came with included batteries. Most of my electronics run on 18650 21700 26650 14500 batteries and such etc. They are just far far more superior in every possible way. I try to modify the devices that i can that use normal single-use batteries to use such lithium batteries. And the ones that i can't i also have loads of NI-MH cells for those devices. In my opinion it is definitely worth investing in at least NI-MH cells for the average user

In my experience with corroded cells, it's the one on the most negative side of a set of cells connected in series that corrodes AND it's the negative side of that cell that leaks. That cell will be at zero volts or near it and the other cells are often OK. This is also the case with NiMH cells in series, but without the corrosion. The cell on the most negative side is the one which will be damaged by being below the allowable minimum discharged cell voltage. How to speed up whatever is behind this I don't know.

@winstonsmith478 2 года назад

@@electronicsNmore I don't get what is causing that. It could be that this happens in equipment where there is a continuous, tiny current drawn even when the unit is off although I believe I've seen it where that is definitely not the case. I don't see how there can be a corrosion preference for the most negative side or, for that matter, either side if no current is flowing.

I've always bought Duracell and Energizer batteries indiscriminately. MANY years ago, Energizers were more prone to leaking. But in the past 5-10 years every time i have had a leaking battery it has been a Duracell. It's gotten so bad that I now remove batteries from anything that won't be used in the near future. I'm ditching the Duracells and switching entirely to Energizers.

@EJEuth 2 года назад

Test should be constant Discharge from positive polarity until eventually it reverses the voltage. My suggestion: Use a power resistor (or an small car lamp) and connect Power Supply and AA battery in series, powering Resistor/lamp. This gives almost constant current discharge. Then comparing how long until Voltage reverses provides an idea battery capacity (mAh) and if/when it leaks the robustness of sealing and gas recombination features.

@Zanthum Год назад

I question whether a better deal actually promotes leaking. A worse seal/a vent may actually allow the gas pressure to escape without pushing the liquid past the seal causing the leak that causes damage.

this is going to be fun. Good to see the chemical reaction. good you are doing a 2nd time just in case.

Maybe try charring it in reverse.

@richardmerriam7044 3 месяца назад

The guaranteed way to make an alkaline battery leak is to leave it under load until it's fully discharged and then leaks. I've seen many people leave good batteries in flashlights for several years and they still leak. The best prevention is to check all batteries in all devices on a regular basis. I have about 20 radios and about 10 flashlights and only check disposable batteries. The rechargeable batteries are topped off once or twice per year depending on whether there is a weather emergency pending. I stopped buying Duracell batteries many years ago. Too many consumer complaints.

@Rudykanal 4 месяца назад

Did not see the current drawn at the time of ventilating. Thinking if the current was higher at one of them, it indicates lower internal resistance. Lower internal resistance could possibly cause this particular test to make the cell crack earlier. Meaning the test may not be revealing the desired result. Low resistance is by other consideration a goo thing. I also tend to think such test should replicate a realistic scenario. I´m working with Panasonic cells i 100k numbers and experiencing leaks at very low currents and way before they are depleted. The pressure in the cells may not hav been hig at all. Just not being tight. I dont know...
