Best Rechargeable AA & AAA Batteries: Esperanza vs Eneloop Pro vs Regular - Worth the Extra Cost?

Hello, I am looking for good batteries for several years. For PLN 40 I found a set of 4x AA and 4x AAA from Esperanza. I suppose it is better to buy eneloopy, but I would like to make sure whether it is worth adding another 40 zlotys to better batteries. Which eneloopy would be better to buy? Pro or regular? Thank you.

Eneloop or any others with low self-discharge can stay in a drawer for a long time. Regular NiMH needs to be recharged monthly.
I use GP recyko + and they are reasonably good. I have been using them for 3 years, so the course of 15 years expected by my friend is still a long way off. I also have a professional black variant and let's say that the camera lasts a bit longer than on standard batteries. In size R03 the Fujitsu is quite nice. In this case, I use the equipment sporadically and so far (2 years) the batteries have not failed.
Like all NiMHs, Eneloop does not like deep discharge. Then there are problems with them - they self-discharge quickly.

Okay, but the entries in the auctions that the batteries have a low level of self-discharge are somehow checked? Esperanza is supposed to be low, but I don't know how many% it is true

Buy at IKEA. They are eneloopy pro.

35 + 15 Shipment, which is the same as on the Allegro for normal eneloopy pro.

Ok thanks everyone for the advice. I will buy eneloopy. I do not close, if someone else could add something, I would ask.

I have a lot of AA batteries at home. They differ greatly in size - some are like "regular" AA sticks, some are a bit larger, and some are so large that I can barely press them in half of the devices and then it is difficult to remove them or close the flap. I understand that manufacturers do this to increase the capacity and write more mAh on the package than the competition, but at home I would rather change the batteries comfortably every 3 weeks than bother with them every 3.5 weeks.

Can you recommend any AA battery model that is sure to hold "normal" AA dimensions and is worth buying? I used to think that it would be the case with the GP, but for the GP model there are different dimensions and a different declared capacity and I lost confidence in this brand a bit.

I have been using Enelopy AA for 10 years. 4 sets of 4 are really irreplaceable.
I recommend.

I confirm that the Enelopes are unbreakable I use them for a camera for several years and they have not lost anything in their value. I have Enelopes from Sanyo but I read that when Panasonic took them over in 2014, they are of lower quality.

I have a dozen AA Eneloop Sanyo cells. Plain white ones. They are about 12 years old. I use them all the time, maybe moderately intensively. Today I took 1 rechargeable battery out of the box, which had been sitting there for at least 2 months since the last charge, and measured its capacity by discharging with 165mA. The final voltage was 1V, and the capacity was 1700mAh. The declared capacity on the rechargeable is 1900mAh.
I charge them with a current of 300mA maximum (usually 200mA) with a Newell C8 charger, and before that with a BC-900.
Not to be outdone.
I add that freshly charged show about 1840mAh.

Fujitsu no longer produces rechargeable batteries, eneloops only white 1900 or ladda 1900.

White eneloop - medium internal resistance, high number of discharge cycles.
Black eneloop - low internal resistance, fewer discharge cycles. Lower resistance means higher current, so better for cameras or automatic wrist or arm blood pressure monitors.
Orange-green eneloop - high internal resistance, high number of discharge cycles. Very good for mice, keyboards, cordless phone handsets (no range problems like mobile phones).
There were also series in other colours, but intended for less demanding applications than white or black.
Recyko makes similar batteries. The white ones quite long-lasting, quite strong, quite capacious. Black with less resistance and green with a little more internal resistance than white. It is worth noting the self-discharge current or rather the rate of self-discharge (loss of capacity). Now, batteries can sit for several years without discharging. There is no need to keep an eye on them to make sure they do not break down from being discharged too deeply during storage.
I will also mention NiMH batteries in the R14, R20 sizes. These also have a lower self-discharge rate, although not as low as Eneloop (Panasonic today) or REcyko (GP).
