  • What is the capacity of a R6 AA 1.5V alkaline battery?
    Can a battery "have amps"? We can correctly say the capacity in ampere-hours or the maximum current that an alkaline battery can generate, this current depends on its internal resistance. The internal resistance of a cell will depend on the type of cell and the degree of discharge and temperature. For a fresh R6 zinc carbon cell, the internal resistance will be greater (i.e. maximum current lower) than for an LR6 alkaline cell (approximately 0.2?-0.3? ;) . A fresh L91 / FR6 lithium cell will have lower resistance (approximately 0.1?-0.2? ;) than the alkaline cell. An additional feature of FR6 cells is their lower mass than LR6 and longer storage period without loss of properties.

    From practice I will add that the useful instantaneous current of an LR6 (AA) alkaline cell with a voltage drop to about 1V can be as high as 2A-4A. For an AAA alkaline cell, it will be 1-1.5A for the same conditions.



    An important parameter of galvanic cells is the capacity expressed in Ah (or Wh), the capacity depends on how long we will be able to draw current from the cell with a certain intensity. How do you imagine what an ampere hour is?

    The capacity of AA cells can reach:
    -R6 1Ah,
    -LR6: 2Ah,
    -FR6: 3Ah.

    Examples of manufacturers' catalog data:

    I met with R20 parallel connection in spark gaps for gas flow water heaters,
    maybe it was about reducing the internal resistance of such a set?

    I don't understand what the purpose of this article is. All this information is available and rather self-explanatory. It's like rediscovering Ohm's Law.

    For people who systematically learned electronics / electrical engineering, yes. But take into account that there are electronics enthusiasts among teenagers, they don't have an electrical engineering course from college or even high school physics, they read what interests them, and such articles can make sense.
    The Electronics for Everyone magazine exists because there are people who would read something about electronics, but are afraid of the intricacies of an academic textbook :)

    Unfortunately, I only have access on the phone and I will not make a table. Pensanic with some pocket weight. In a few other cases, the Rw could also be up to 2 ohms with some free batteries, the rest were relatively fresh. What is the capacity of a R6 AA 1.5V alkaline battery?

    What is this article supposed to represent? The engineer should be data driven. So in this case on tests or catalog notes, and not on your "whim".

    See in which section this article is placed.

    Beginner Electronics

    I think it might be useful to them, although the article is very sketchy.
    It would be worth, for example, to write more about Rw, at least the way it is measured!
    Because someone else accidentally had a multimeter set to ? will want to hit her ...

    @Cockroach the more there should be a reference to some catalog note. Let beginners educate themselves to check component parameters, not to copy mindlessly.
    For example, the Varta Industrial LR6 battery has (https://www.tme.eu/Document/4625fd5330c463bc44336a2038117f0c/BAT-LR6_V.pdf) capacity of up to 2.8Ah, depending on the discharge conditions. And you take some Chinese or "marketer" and you can never exceed 2Ah for alkaline AA.
    The maximum and recommended current is also in the note. There are links that can handle 2A well, and some cells that will tire with 1A.

    I am asking the author for forgiveness, but in my humble opinion there is a basic error in the title of the thread ... What does it mean "How many amps have a battery"? A mistake in the vocabulary, because I don't think that in terms of the essence of energy storage ...

    This is something similar to the question of how many Hertz a TV has.

    The beginner's question about the possibilities of cells usually sounds like this topic ...
    I am fully aware that the battery "has no amps" and the socket "has no Hertz" :) and the title of the material is not perfect,
    I am counting on the fact that:
    -seeker exactly this phrase they will find the answer
    -the content of the material will present how (at the beginning) to correctly characterize the possibilities of the cell

    Well, I don't know ... You didn't convince me. The search for a phrase can also be in the text, not only in the subject. And because (as it still seems to me) we are on the technical forum - the topic should be truthful and have the right nomenclature. Personally, I fight with flowers such as "230V Current", so this title also made me gag.

    Everyone has an opinion and that's it
    the title of the material attracted people who expanded the content of the material with their posts, which is very beneficial.
    From my point of view, the discussion of the content of the material is more important than its title.

    Four materials from the last days in guides:
    https://www.elektroda.pl/rtvforum/forum505.html
    relate to basic issues that may be of interest to beginners,
    such basic topics often develop a discussion that begins to touch upon more and more complex issues,
    In this way, you can learn interesting things by reading the statements related to the original short and simple content of the material.

    And it's not easier to correct the question (preferably in two)
    1. What is the current efficiency of the cell? - that is, how many useful amps will flow to the receiver (and here we take into account the internal resistance of the cell)
    2. What is the capacity of the cell? - how long will the receiver work with the specified power consumption, i.e. how many amperes they put into the battery (and here the cell's capacity is expressed in Ah - ampere-hours)

    And so, for example, the Varta R6 has a capacity of 1.8 to 2.7 Ah depending on the type of load and operating conditions. In this chart, the duty cycle is defined as one hour per day. And the second assumption, the current flowing from the battery will not exceed 0.25A, probably at high loads the battery will end its life quickly.
    So in the end - alkaline batteries do not like heavy loads, the assumption is max 0.25A or a light bulb with a nominal current of 0.3A. And the amps in it sit from 1.8 to 2.7 in the typical operating range and operating conditions.

    The title attracts the most attention of young adepts of electronics and electrical engineering.
    As a technical one with many years of experience, I just often need to flex intellectually in order to explain the basics of electricity, sources of electricity, etc. to the non-technical and small-tech ones.
    I once had a scratch with a "sales representative" who happened to be from Duracell.
    I asked for full battery data - alkaline cells, just in terms of capacity. The lady immediately stated, there is no such thing, batteries are batteries, only batteries have capacity ...
    Over time, the lady serving my area has changed. I repeated the query.
    This salesman's copy turned out to be more cooperative, she grabbed the phone right away and started calling her tech support.
    The result as expected - a similar answer to the predecessor :-)
    Well, the internet and let's do it.
    The Polish side of Duracell - technically a failure - only promotions, contests, advertising materials, etc.
    Duracell USA - there was everything you needed for happiness. I downloaded catalog notes and printed them.
    At the next visit, the most charming, but altogether very nice and intelligent lady sales representative from the battery, handed her the prints.
    This is for you, homework done, R6 / AA batteries have such and such capacity of ampere-hours etc .... You have been collecting your jaw from the floor for a long time :-)
    Returning to the disputed title "how many amps does the battery have?".
    It just cannot be otherwise. So now they teach in technical schools that if an ambitious student does not learn on his own, he will not achieve anything.
    What can I say myself when the apprentices from the University of Technology could not handle the simplest multimeter and chose an internship in a telecommunications-broadcasting company ...

    Especially since it's not true. Most people think they have a charger for their phone, and that's just a power adapter - and the charger fits inside the phone. Some modern power supplies could act as chargers, but they are power supplies anyway.

    It depends on the facilitator. I had people who talked about crap for half of the lecture, and in laborkas they sat in the closet most of the time. But I also had people who described in detail and interestingly, solved problems right away, and on labs they saw exactly who is doing well and who is not.
    Technical secondary schools also prepare rather poorly. Remember how in laborkas my colleagues from technicians mostly did not manage to connect even a wattmeter and they could not understand each other, and people who graduated from high schools quickly understood this topic and quickly caught up with the lack of technical knowledge and chased them away.

    One woman asked for a laptop cable - after the investigation it turned out that it was a power supply that was needed.

    I was taught (I don't know, maybe something has changed in this regard in half a century?) That a battery consists of cells. So, for example, a 6F22 battery consists of several cells connected in series, each of them producing a voltage of about 1.5V.
    Similarly, in the phone - there is no battery, but a battery ... A battery, in turn, can also consist of several battery cells - right? Naming changes, the way depends on the interpretation and (unfortunately) results from the lack of knowledge of the majority of society what is what. An example that (probably because of my interests) irritates me the most is calling portable "self-playing" (speakers, housing, amplifier, power supply and battery - sometimes a radio) "SPEAKER" - a speaker because what? Because loud? And in fact (see earlier) it is a portable amplifier with a built-in power supply, an amplifier and an MP3, USB, BT player module and God knows what else. And the speakers are only a part of this device ...
    There are many more such "kfatkuf" in common speech / nomenclature; The only question is whether in the technical forum we should equal the (low) level of knowledge of the general public, or (similarly to the example of Col. OldSkull) require and equal the best?

    True.
    Only that these cells connected together form a storage battery. A battery is, by definition, several identical pieces joined together. And not only in electrical engineering. For example, cannons working together also form a battery.

    Well, brother, now he showed eloquence ... :)
    Seriously, if you think it is correct to write about the amps in the battery, I have no questions.
    Such simplifications may appear in everyday language - among non-professionals and we do not have any influence on it, but (in my opinion at least) the technical forum (and I still consider the Electrode as such, after all) should have its requirements (and it has - in the regulations) ) and "level up".

    Do you like verbal games: Battery

    I know that this is not the best way, but I have been checking the condition of batteries / cells / accumulators for a long time by measuring their short-circuit current reflecting the internal resistance that increases with the consumption / discharge of the cell. Measurement of voltage without current load is misleading because even a discharged AA cell can show 1.5 V.

    Nobody mentioned; A fresh AA NI-MH rechargeable battery can give a short-circuit current of 10-12 A.

    Well, you wrote that there is no battery in the phone and I still use cells from an old Nokia where there was an accumulator battery consisting of 1.2V cells :) .
    I know that today there is usually one 3.7V cell and it is not a strictly speaking battery.
    But when you go to the kiosk, will you ask for an AA cell or a big finger battery?
    Anyway, there are no kiosks any more.

    And while writing about the cannons, I also thought about the sink faucet and found no explanation, unfortunately.
    It was also said that there was a bottle battery (prepared). This appeals to the imagination more :) .
