Hello Jens. This does not matter for most devices. Batteries only have a nominal voltage of 1.5 volts when they are brand new. This voltage decreases with batteries in the course of use. Rechargeable batteries have a more stable voltage over time. This means that practically all devices must be able to cope with a certain voltage range. In general, rechargeable batteries should be used for devices that consume a lot of electricity (flash lights, cameras, toys, etc.). Batteries in devices that consume little power or are used only rarely (remote control, thermometer, etc.). Reason: unused batteries discharge much less quickly than unused rechargeable batteries. Greetings, Michael
I noticed that the rechargeable batteries are slightly thicker than the normal batteries. However, by "slightly" we are talking about fractions of a millimetre. In the case of a template cast to the hundredth, this can be a problem because the bodies do not fit into the shell. I have been using the batteries in various devices for years: Telephone receiver, clockwork, computer mouse, remote controls of HiFi components etc., with me the deviation has never led to complications. But I can understand why there might be a problem with the accuracy of fit in your area of application. I don't see a solution, except that you switch to normal batteries.
I don't think that Power or Endless make much difference here.
There are more important factors.
I use batteries with a large capacity whenever possible and operate almost all devices that actually need batteries with them.
It should be noted that rechargeable batteries only deliver a voltage of approx. 1.2 volts, whereas batteries deliver 1.5 volts.
This means that a rechargeable battery has to supply more current to generate the same power and therefore often lasts much less time than "real" batteries.
In addition, wireless phones often have charging stations, but these are not very intelligent - which means that the battery suffers in the long run.
But these things are the same for all batteries.
The Endless is completely sufficient for a wireless telephone in the home. The capacity depends on the duration of the call. For normal private use, the 750mAh is sufficient for several days of stand-by operation.
The capacity has nothing to do with it. The mAh specification only tells you how long a battery lasts, so to speak. It therefore does not matter whether you charge 2000mAh or 3000mAh batteries. It doesn't matter to the device.
These batteries are nickel-metal hydride (NiMH) type and can be recharged using a compatible NiMH battery charger designed for C-size rechargeable batteries. The charger must provide the correct voltage (1.2 V per cell) and be suitable for NiMH chemistry. Charging typically involves placing the batteries in the charger with correct polarity and connecting the charger to a power source until charging is complete.
Note that the Varta plug chargers mentioned in the sources are designed primarily for AA and AAA NiMH batteries, so you will need a charger that supports C-size NiMH batteries specifically. Always follow the charger manufacturer's instructions for safe and effective recharging. The charging time depends on the charger's specifications and the battery's degree of discharge but usually ranges from a few hours to overnight.
This type of battery should be discharged at regular intervals and then recharged (memory effect.
Otherwise there is exactly this 'phenomenon' when they are always in the charging cradle.
I would interpret it like this: A device with a uniform energy demand "sucks" a relatively constant amount of energy from the battery, for example a wall clock, a remote control,... As an opposite, I can think of a remote-controlled car that needs much more energy when driving at full throttle than when driving slowly.
With this offer it is possible to order only 2 pieces without any problems.

For products that are not only offered by us, but also by third party retailers, it may happen that there is a different minimum order quantity for each supplier.
No, a charger will not be included. The "Rechargeable battery + charger" is marked with product type. This means that this product is filed in the category "Rechargeable battery + charger". This has nothing to do with the scope of delivery.
The batteries usually have a size indication, such as AA or AAA. If you are not sure, you can also measure the battery and indicate the diameter and length. The manual, inside the remote control slot or cover, or on the battery itself should normally indicate the designation.
