Comparing AAA Varta Ready2use 1000mAh and Eneloop Pro 930mAh Rechargeable Batteries

So far I had Eneloops AAA Pro 930mAh . I will not say,they are great.
Price for 4pcs 55zl.

Today I see you can buy Varta Ready2use AAA 1000mAh.
Price for 4pcs 30zl.

Difference in price almost double.

Can you say something about AAA Varta rechargeable batteries ?
Ticky price,but will not "run over" ?




ps. i searched the forum but the topics go back a few years and not much can be found

Eneloop are unrivaled. Varta does not grow up to them. I bought one set of Varta once, because I used the batteries more than once and have a good opinion of the company, but the rechargeable batteries disappointed me a lot. I tried to use them in a camera, a fact, demanding a lot from batteries/batteries and it was a failure, it instantly signaled too low voltage. I put them in a thermometer (a weather station with a clock) and also a failure, despite the small load they died quickly.

I subscribe to this, based on years of using Eneloop rechargeable batteries. Top it off with a decent dedicated microprocessor charger and there is nothing better. Eneloop-batteries lasted one winter in (I think it was 2008, when it was below -20 degrees C at night) in solar lights outside (the lights were on every night). To this day, the rechargeable batteries work flawlessly.

hmmm Someone will say,why are you pasting this when you know better?
I just don't quite trust the tests on the web,but it certainly gives you food for thought.
Varta is on par with Eneloop here.This is a test table for AA batteries.

I wrote you down because I happened to use both these and these, although the fact is that eneloop in a larger quantity (about 20 pcs.) and Varta only one set of 4 pcs.

From those in the table I also used Sanyo 2700, and it would be difficult for me to praise them, because although they have a large capacity, they also have a very large self-discharge. They are probably suitable for, for example, powering toy cars and other similar applications, where capacity and the ability to give up energy in a short time are important. I rather value long-term energy conservation and here eneloop are unbeatable.

For example, in the weather station eneloop (the same set of 3 pcs.) I use about 6 years and charge regularly in the spring and autumn. No problems at all. And yet eneloop have only 1800mAh (the white ones). Sanyo 2700mA ones probably last less than a week there. And what do I care about their 2700mA, for which they certainly got a lot of points in this table, if they lose them in a couple of days? Incidentally, they didn't shine with durability either, the 6 years of service life they already have behind them eneloop can't even dream of.

What advantages does Varta have? I don't know, I haven't discovered. Maybe it just can't get along with my charger? I don't remember the details, but I think the accepted charge was much lower than nominal. As far as I remember their main drawback was low operating voltage. In the end, I think they ended up in some remote controls and there they somehow manage. With emphasis on "somehow".

For me, a reliable test would be to test rechargeable batteries up to the contractual limit of usage.

Varta is softer than Eneloop I suspect it has more internal resistance(you need to check in the specs) see '' average charge time for Canon lamp'''

I have in front of me Eneloops 750mAh,pieces 7.
They are about 6 years old.
This is probably the end of them.
I also have a BC-700 charger.Very popular if you look on google.
I will try to "Refresh" them, although I do not expect them to be like new.

How is the case with such batteries after 6 years? Decreases their capacity or energy storage time,or maybe something else ?

My eneloop AAs are performing great after 6 years. I charge them twice a year in spring and fall and they power the weather station. Maybe the secret to their longevity is a small number of charging cycles? How many have passed yours?

Sanyo 2700mAh after maybe two years of use in the camera (a total of maybe 20 - 25 charging cycles) rapidly increased self-discharge. The capacity they had, but you had to use it in a maximum of 1 - 2 days.

I do not want to start a new topic, so let me elaborate here...

I put 4 rechargeable Eneloop batteries.
I set Charge Test means I wanted to measure how much capacity they have.
I had a choice of 200,500 and 700 mA.
I chose 700mA.
After about 20 minutes of the test,suddenly something fired,such a "bang",like a bomb from a paper bag
I look,charger is fine,display is lit,no smoke.
I disassembled to see if any component did not "swell".
Everything normal.

What could have happened ?

I think you should, because your problem is quite different from the Author of this thread.

So what does the charger charge? Have you measured what voltages it gives, what is the charging current?

But you did not post any picture, nor did you give the model of the charger.
