There is a Wireless Light Switch at work, lies with me on the table. It is time to change the batteries, open, and I see the AAAA size batteries. As it turned out to be a very rare size for Russia, I found a couple of such batteries for 150 rubles. The toad strangled immediately.
But knowledgeable people suggested that some Crohn alkaline batteries with marking 6LR61 consist of 6 AAAA elements. Salt crown 6F22 is not suitable.
The experiment was purchased 2 crowns of manufacturers: GP, KODAK (the average price of the crown 70r).
Croon GP Super did not praise hopes, it consists of rectangular alkaline elements.
But Krone Kodak Max inside itself contains 6 Bathoreks of the AAAA sizewo.
Duracell crown, also contains 6 AAAA batteries.
