They are rechargeable batteries. They do what they say. If someone has enough, it is worth buying the charger from the same company.

For at least 15 years, I have considered Eneloop the top rechargeable batteries, and they have never disappointed me. I use these specific ones in a cordless phone. It is true that they come pre-charged, so I placed them in the phone and left it for a week before charging it, ignoring the "battery empty" indicator.

Low capacity for low consumption use. For the night light that I use them in, they are just fine, but for the keyboard, they lasted one day.

It is what they say. Lite. Adjust the usage accordingly

The best one can find for mice, keyboards, air conditioning remotes, etc. They do their job.

Installation on wireless phones a Panasonic and a Siemens. They last for days without daily charging. It goes without saying that we don't leave them charging all night, only when needed. In a house and a store with many phone calls.

The best batteries on the market. These specific ones are for use in devices with low energy consumption such as cordless phones and TV remotes. However, you will also need a charger.

Pre-charged you can't call them, when placed in the wireless phone they were almost empty (unless the manufacturer means that, then I pass).
HOWEVER, they show excellent batteries. A full charge was made without interruptions, it has been 3 days with normal use outside the base and the phone indicator still shows them as full.
So far they are flawless.

It was installed on a wireless phone, and its functionality changed 100% in its use. Ideal for replacing the wireless phone.

For a DECT wireless phone, it's great and lasts longer than others. Of course, you charge it once it shows the need for charging and as soon as it's complete, we remove the wireless from its base. Time will show the durability issue. After 3 years, they continue without any problems.

I bought them for a wireless phone. They last 3-3.5 days with the phone closed at night. I would expect them to last at least 5 days. Let's hope they hold up for a long period as the company claims.

How to evaluate batteries, since (everyone) manufacturers do not provide lifespan... They seem to be worth their money, but you can't know with batteries! Anyway, they perform well in terms of quality, because the device I use them with (pressure gauge) is a bit "picky" in this matter - it doesn't work with lower quality ones!

value for money, you simply forget to charge it. It lasts for days up to a week.
After 4 months of use, no issues, it can last in standby mode for a week or even more for sure. I don't regret buying them

These specific batteries are worth NOTHING. I bought them for use with a cordless phone according to the manufacturer's specifications. Unfortunately, after charging them as recommended by the manufacturer, they would not last more than 8 to 10 hours, often without even using the phone, just on standby.
