I have no complaints about their performance and duration. I would even say I am amazed at how long they last. I use them for night observation binoculars. I just can't understand something: while I charge them with an Xtar X4 charger and it shows they are full, when I put them in the binoculars it shows they are at about 60% to 70%. But as I said before, they last incredibly long. So far I have charged them 3 - 4 times.

This particular batch was not good compared to another one that lasted longer. Almost all of them went bad, they didn't last at all. The purchase was made from Fotomarket and it had a 2022 date, I don't know if that played a role.

I bought them to make an 8-piece battery pack for a device I use at work every day.
No comparison with the worn-out ones from the old battery pack.
The device's autonomy has now skyrocketed...
While the old ones barely lasted 7 days (with 4-5 hours of charging) and would suddenly cut power, these have exceeded 1 month on the initial charge without even showing a recharge warning yet...

I use them mainly in my child's remote-controlled toys or other similar games, and they have very good durability in use.

For use in Speedlight (for DSLR) Godox TT685N II, in wedding/baptism environments, they are good and have great longevity, but with quite a few misfires. Possibly the Speedlight itself also plays a role in this.

They are considered the best on the market for this use and I haven't tried others, but the above combination is not perfect.

Overrated I think they are not worth it unless you have small children who constantly need to charge batteries

First charge at 500ma. I will return if the capacity drops.

Regarding premature capacity drop and devices like "smart locks, cordless phones, etc.", please inform yourself about "trickle charging" and "overcharging" and how these destroy batteries, especially when the charger for these devices is of poor quality without BMS.

This is the second set I have purchased, I measured them with the Vapecell S4+. The new ones, like the ones from two years ago, are 2520 to 2560 mah. Excellent.

Classic value. Once you start using them, you forget about the disposable ones. I have been using them for years in combination with a quality charger and I might have thrown away one set in the last 5 years.

Better than other rechargeable batteries. However, they do not maintain what they advertise regarding voltage drop when stored.

I have had them for 2 years. Their use is for my 2 Xbox controllers. I have truly forgotten what charging means! They easily last for 50 hours (with the controller's LED turned off). Also, the batteries don't run out easily, even if you stop using them for days. Their performance hasn't dropped at all, and I have charged them around 15 times.

I have no words for these specific batteries. Used them on a demanding old DSLR (Sigma SD10) where the rechargeable CRV3 batteries were the only option. With a battery grip and 8 of these inside, the number of shots I take has more than doubled. But the most important thing is that even though they have been in the camera for about a month, they do not discharge easily. It is important to have the right charger, I paired them with a Jupio 8-slot charger.

Excellent batteries, I have been using them for about a year for Xbox controllers and I am extremely satisfied. They last much longer than commercial batteries.
The only problem I have encountered is that sometimes they don't charge 100% in one session with the XTAR VC4 charger.
So I have to put them back in until the charger shows that it has charged close to the capacity in mAh indicated on the batteries.

What can I say, you get what you pay for. These replaced other rechargeable batteries from a well-known company. I have put them everywhere (where batteries are needed) and of course in the Xbox One X controllers that I have. Besides the fact that the build quality is very good, I also noticed a huge difference in their duration, meaning that while the others had to be charged 1 to 2 times a month, these, as soon as I got them and charged them once, don't need charging anymore (it's been 27 days and they still last).

I would definitely buy them again, I also got AAA ones for the air conditioner controllers, television, etc. They are worth it.

If batteries don't lose even one flash with full power in the flash, then I only have good things to say! With eyes closed

I bought them in early February.
I put all 4 of them in a landline phone.
They lasted until mid-September of the same year.
When I took them out to charge them, after a corresponding warning indication from the phone, one of them had a voltage of 51mV (0.051V), while the others had around 1.15V.
There are chargers that do not charge the battery at all when it has such a low voltage (51mV), while others do charge it. I have chargers of both types. However, even if you charge such a battery, its voltage will drop low and it will not perform well.

I did not expect such low quality from Panasonic, especially considering its price.
I was ready to buy another set of four after the first charge (I already had them in my Skroutz basket). However, after this, I am back to investigating.
Unfortunately, though, this problem occurs in a large percentage of rechargeable batteries (of any brand) that I have tried.

The best purchase I have ever made. We need batteries every 4-5 days. With the Panasonic Eneloop Pro Rechargeable Batteries, I have saved a lot of money

I bought it for the Xbox Series X controller, and I'm saved. I forget to change batteries! It literally lasts me 3 weeks!

I received today the "pre-charged" batteries as the package says, with a production date 10 months ago, meaning 5/2021. As soon as I put them in the mouse, they had a 67% performance. After 4 hours, they have dropped to 56%. What scares me is that the paper says that in 1 year, the performance will be 85%. And I'm afraid that if the purchase is of an "old" package, the batteries lose performance. Obviously, it is impossible to ask for "freshly cut" ones. Today is 23/03/2022 and I will come back when the batteries need to be charged. So, how long does a 2500mAh battery take to deteriorate unused? The essence is that 67% at the beginning and 11% loss in 4 hours of mouse usage tells me mathematically that in 1 week of mouse usage, they will need to be recharged. Something is wrong when new mice with 2 minutes of charging have 9 hours of usage.

For years now, I have been using Eneloop (pro) for my needs (gamepad, landline phone, wireless keyboard, etc.). I am very satisfied and I see no reason to change them.
I have read that Lidl has the exact same model under its own brand at a much lower price. However, considering that rechargeable batteries will withstand many charges and discharges and are essentially an investment, I don't see a reason to risk it to save 3 euros.

the best in battery performance and durability over time.. I wouldn't change brand for anything. Even the Duracell 2500mah I had in my possession in the past lasted 8 full years of daily use.

Very good batteries, I use them for my gaming controllers. The prices are accurate and correspond to reality

I got them with a charger perfectly, 8 batteries, I forget to charge for charging after 6 days Xbox Series S-X, I recommend getting it better than a large Microsoft battery, they last longer than we think Enloop 2000ml

There is no other battery that matches its performance! Recharges the flash faster than many other brands! They last perfectly for 3-4 years with not very heavy use. You simply replace them for peace of mind and use the old ones in remote controls ;-)

10-15 hours of duration on the Xbox Series S controller. For me, it's great if you consider that they charge again in less than 2 hours. I would buy them again.

I have bought them for the Xbox controller and they have twice the durability of the Xbox kit.
Attention, they do not require a cable to charge but the Panasonic charger, and they work perfectly

I bought them for my Xbox Series X controller, but they have an issue with charging. No matter how much I tried to charge them with the controller, it didn't work. Maybe they need their own "charger".

Over time, I have had various rechargeable batteries. I had various problems, maybe even from my own misuse of them. From the moment I bought this specific product, I understood their superiority on all levels. I highly recommend them for any use.

Excellent, I use them for GPS and they last at least 2 days with 7-8 hours of daily use. I don't know how long this capacity will last, but for now, I am very satisfied. I bought them because they had very good reviews. Their performance decreases to about half in around 10 months.

If you charge them for one year, you will have 80 to 85% of their power. The quality is evident. I highly recommend them.
