Amazing.. I am leaving a review 4 years after the purchase as I now have an opinion after use.. EXCELLENT, they still hold up strong after dozens of countless charges.. Very slight, almost imperceptible drop in duration but that's to be expected now..

I recommend

11/11/2025 and they are installed in a cordless phone and work just fine, they hold at 80% compared to when I bought them.

Placed (2 pieces) in a Siemens Gigaset cordless phone. Even after a 2-hour call, the phone's indicator shows a fully charged battery.

Theoretically good but discharge quickly. Expensive and not as they promise that the charge lasts for a long time. The price is not justified compared to the competition.

For now, I charge them once a week without excessive use of the phone. They seem good. I give four stars because it's in the first month of use and I am reserving judgment. I would say I am satisfied.

So far, flawless.. I solved the problem with the batteries... Anyone who has small children understands..

Excellent batteries, I have been using them for about a year for my wireless mouse and other general use devices. I am completely satisfied. They last much longer than store-bought batteries.

Excellent.
Panasonic consistently produces some of the best batteries.
I have been using Panasonic rechargeable batteries since 2000 and they still work perfectly, having only lost about 25% of their capacity after all these years!

I have the Eneloop AA batteries which are really unbeatable. I have read very good comments from other users about this Panasonic series. I have the larger AA batteries in a blood pressure monitor and after 8 months they haven't even dropped halfway. Eneloop batteries are widely used by photographers, as they know their durability and quality.
These batteries are also COMPATIBLE with CORDLESS DECT PHONES.
An exceptional product from Japan! MADE IN JAPAN

Πρακτικά δεν μπορούν να αξιολογηθούν από μένα σε τόσο σύντομο χρονικό διάστημα όσον αφορά τους κύκλους επαναφόρτισης και την χωρητικότητα τους. Μέχρι στιγμής δεν προέκυψε κάτι αξιοσημείωτο με την χρήση τους.

Σταθερη αξια εδω και χρονια,εγγυηση,κατηργησα καθε αλλη μαρκα που αργα ή γρηγορα με αφηναν ''στην μεση'' οπως λεμε.
Τις δουλευω σε φακους Led αλλα και σε αλλα πχ ποντικι pc.

They are used exclusively in the Gigaset A420A (one pair at a time, of course).

From fully discharged, the XTAR V4 shows 700-741mAh, so at least they are true to the advertised 750mAh.

With this specific DECT phone, the battery life is approximately 7 to 8 days, mainly on standby with minimal phone calls. For 750mAh, it is okay (previously, with 1000mAh batteries, the autonomy would reach 10 days).

When I have an opinion about how many discharges-charges they will withstand and when they will start losing capacity, I will come back.

So far, in the 3 charges, it seems that they charge normally and their performance is satisfactory.

I have been using these specific Panasonic batteries for years in various devices.. I have never had a problem

I installed them on my wireless phone. I have had them for 2 months now. From the first moment, it was evident how good they are. With moderate use of the phone, they last several days. Very satisfied with this product

τις είχα για πάρα πολύ συχνη χρήση σε ασύρματα τηλέφωνα και έπεσε λίγο η απόδοσή τους μετά από 8 χρόνια περίπου. Ξαναπήρα τις ίδιες και ελπίζω να κρατήσουν όπως οι πρώτες.

I have been using eneloop batteries for years and they haven't had any issues with countless charges and discharges. I use them in all devices (remote controls, mice, phones, etc.) and I no longer worry about buying regular batteries. They do not lose any energy no matter how long they remain unused, always ready for use.

I have changed almost all of the batteries. They are perfect for my little one's toys, remote controls, and many other things. They are worth their money. I want to buy them again.

After 4 years, they work just fine while other cheaper long-lasting ones I bought later were useless after the second charge. I recommend them!

Τις χρησιμοποιώ παντού, σε ασύρματα τηλέφωνα, κοντρόλ, ποντίκια, πληκτρολόγια, γενικά όπου χρειάζεται. Είμαι απόλυτα ευχαριστημένος απο την αντοχή τους για το χρονικό διάστημα μεταξύ των επαναφορτίσεων, αλλά και της διάρκεια ζωής τους

The best thing, affordable and work perfectly on a wireless phone. They don't discharge and are made in Japan

For anyone who hasn't tried them: Eneloop is perhaps the best compromise between quality and cost for rechargeable batteries. To find something better, you would have to spend a lot more money.

Warranty. They are effective. They actually retain their energy over time. I trust them. I think they are one of the best options for a rechargeable battery.

In combination with the original charger, they are perfect and charge quickly. I have replaced all the conventional batteries in all the devices in my house.

I have had them for 1 month and we are talking about incredible durability compared to other batteries in the same price category.
The phone that used to charge every night, I have had it for 3 days and I talk constantly!

The new ones are perfect. I am writing this comment about Eneloop batteries that I have been using for over 10 years. They work just like new now that I needed them again

There is absolutely no reason why someone should not choose it. I have bought many different types and brands of rechargeable batteries. No other product has the durability and stability of these batteries. They may be more expensive, but they are truly the best rechargeable battery I have ever purchased. They are worth every penny, 100%.

Durable with most devices. Only for landline phone, I might prefer a larger capacity. Very good price
