Then you did something wrong: Added acid instead of water, or not applying temperature comp correctly. There is no way to charge a battery and end up with stronger acid than shipped from factory.
No, I don't add anything. Maybe didn't compensate correctly, I'm just learning to use the hydrometer. Maybe I read wrong. I don't know.
Without proper temperature compensation, the readings are not useful

Ok I have taken measures again. Here are some pictures. Help me undestand the reading. By point, means .005 in difference? Example 1.275 + compensation of 2 would be 1.277? What are the values between numbers, 1.225 to 1.250 are increments of .05 or .005?
The hydrometer should have come with instructions on how to read and compensate it. Or you can google hydrometer instructions and chose winemaking, or battery acid, all the same sort of tool.
Rinse with distilled water before use, and again afterwards. Acid residue is really sticky and will gum things up and it won't read right, Also beware any tiny bubbles sticking to the float,
