AA Battery Test - which are the best? Which are profitable? Which are you overpa

Does not make sense. Nothing special will come of it. The ranking will be close.

But it does not have to apply to batteries, e.g. rechargeable batteries.

The batteries are the best. However, maybe someone on YT has already done it recently and it's enough to discuss it now.

Virtually all. This is called electrode depolarization.

Can you explain it to me or give me a link where I can explore this topic.
For me, depolarization has always been associated with reversing polarity.

What you are talking about is reversal. Depolarization consists in the automatic removal of harmful substances or gas bubbles that form on the surface of the electrodes when current flows through the cell. After some time without current flow, these substances are deactivated, increasing the active surface of the electrodes, which translates into an increase in cell efficiency.

Thanks for clarifying the term.

A very nice test. In my opinion, 300mA is a good value. By checking with such a high current, we also check the quality of the materials used to build the battery. Namely, the internal resistance of the battery. The smaller the better, the more current you can safely pull. There will be no problem if we put a battery with a low Rw into the remote control or watch. But if in the 10mA test it turns out that the X battery will be the best and everyone starts buying it and putting it in toys, flashlights etc. where the current is high and the battery has a high Rw, then there would be a problem. It would rain quickly, pollution, costs, etc. And it would turn out that for many such a test would be useless, because for applications with higher current it would still not be known which batteries to buy.
I bought myself a few years ago on aliex .. such a small tester.

As a load, I connected a 7.5 ohm resistor and set the end voltage to 0.9V. I have already measured several batteries and accumulators. My results cannot be directly compared to the measurements of others, but due to the same conditions, I can compare my measurements. Lidl was the best for me. And GP is the worst. Varta industrial all blue very good. And with the Energizer recharge battery nominally 2300mAh.

I am testing R 14 batteries in clocks with an R 6 battery I accepted, the R14 battery has a large capacity

How did you put it in there?

I soldered the tape from the laptop battery to the poles of the R 14 / R20 battery, and the R 6 battery with pole insulation to hold the tape - plates It is easier without soldering the battery baskets R 14 R 20
P.S. above scribble applies to wall clocks

How long does such a test take?

In my clocks, an AA battery lasts for such 2 years, which means that R14 (C) should last for 4-5 years.
I wonder why my colleague performs such strange tests, it is known that the larger the battery, the greater the capacity (we are not talking about fakes).

There are a lot of battery tests on the net, various testing methods, for example here:

I use a lot of batteries (I buy them in bulk), mainly for interactive toys, so before buying I watch the available tests and do the financial calculations. Unfortunately, when shopping online, there are fakes of even branded batteries, which can only be found after some time. I will not give the name, but one of the branded AAs, with a very good term, poured out after a few months of use (it was found twice in different devices).

Only R14 is not a battery. How can electronics not know this?

OK, a battery must have at least two cells, but colloquially a cell is a battery.
The author of the topic, admin DIY also uses this vocabulary

One of the most interesting technical bloggers undertook to examine over 50 models of various AA batteries, i.e. the most popular "finger".

Do you personally think it's a linguistic error? Or technical? The word battery seems to stick strongly to 1.5V cells

Oh, it fell hard like many others, e.g. LED bulbs. It annoys me but hey, it's a fight against windmills

There is a big problem with this, the AA "battery" is a cell, but e.g. a 9V block is already a battery because it consists of several cells,
the battery is reserved for rechargeable sources, interestingly, inside the VRLA 12 there are 6 "cells" and it is still a battery no matter how many elements it has, for Li-ion batteries in the packages there is often a number indicating the number of elements connected to each other.

The same thing as with the "LED bulb", it's a mistake, but everyone knows what it is...

In general, I try to use these terms correctly, but I happen to write / say incorrectly, but as long as the recipient knows what it is about, it's ok.

Easier (or maybe harder?) is in English - battery and that's it.

Eno, there is a word "cell" for a link (electric because it is different for a chain and in turn it is the same with us. And how to get along without context ).
It's common to say "battery" for a car battery in jargon.

It's actually 'cell' also goes with 'fuel cell'. In the UPS, the batteries connected in series are string/string.

In Germany, even industry people won't say AA Zelle, but AA Batterie.

I hate these naming conventions. Ask your "baby" what an AA cell is and if she sees it, she probably has a mustache.
By forcefully using specialist terminology, we close this forum to new users. I was taught that in order to teach someone something, you need to use simple everyday language.

We've gone a bit off topic, but that's okay. Continuing with the naming there is confusion with confusion.
An electric cell is called a battery, but a chain link is not called a chain. A light bulb is colloquially referred to as both incandescent and LED light sources, but somehow I have never met an electroluminescent bulb, only a fluorescent lamp.

Then go to the kiosk and tell the saleswoman that you need to buy an R-14 battery.
This lady's face will be priceless when she sends you to the auto parts store.
Or that you need a 10W LED light source for E27.

But if you say "R14 battery" she will probably already know what's going on.
