For my purposes, not useful, ...

Hello, I've bought these rechargeable batteries for my in-ear transmitter with band performances, as after a gig are always empty and every time new buy unfortunately in the long run the Gage wegfrisst ;-)

Unfortunately, many high-end products are a result of your held Extrasmall shape or design for a perfect fit
Space-saving and for that matter the battery compartment. Normal AA batteries fit well in and come out even on its own again, or very easily get out, Attention, these ones are from Ansmann thicker than normal batteries !!!
Since they are embedded in my device from above and there is no lateral access to the batteries do I have to rely on the fact that they are easy to take out again with the flip open. They went inside and barely not get out more than ever! Much too big, so I had to pull a Spitz Ange on the batteries to them at all to get out, which may not be a solution in the long term but, as a result, the lining of the battery is damaged and it may eventually leak permanently, ....

Will probably even have to try another brand, or halt but unfortunately batteries must return again to the 1x use ....

As for battery life, so I can not complain, the hold as long as the normal, but not really any longer.
