Today I received the specific battery. The color and shine are exactly as shown in the photo. It has a nice mechanism. Reliable company. The purchase concerns 2 pieces.

Update 24/7/2024

After 1.5 months with cleaning only with mild vinegar and a damp cloth (to avoid scratches) on the handle that opens the battery, it has a dullness and the color has faded a bit. Chemicals should not be used on any colored object, whether it is gold, black, etc. Of course, we know that the quality of products has dropped significantly. I know this because the same thing happened to the rubber of the gun in 2 gold Armando Vicario showers I bought. It's a shame to spend so much money and not have them last long.
