    Hi
    Yesterday I purchased a 9V battery. here is a picture of it:

    But there is something on the backside:

    Three question:
    1- What does mean "transitor Block"? IMO because there is several Battery cell within it.(https://en.wikipedia.org/wiki/File:9V_innards_3_different_cells.jpg)
    2- What do mean those symbols?(I marked with red circle and rectangle)
    3- Why do they say "For Brazil only"?

    1. I suspect it is supposed to be 'transistor block'. It is for transistor devices?
    2. I think, rectangle left to right.
    2a. Connect with correct polarity
    2b. Do not short circuit
    2c. Don't cut open
    2d. Don't incinerate
    2e. Don't charge
    2f. ????
    2g. Don't mix battery types
    2h. Don't mix new and partly discharged batteries.

    I don't know what the circled symbol means

    3. I don't know but it may be a tax thing.

    The symbols in the rectangle mean:
    • This is the correct way to insert the battery
    • Do not carry with keys
    • Do not store with metal tools
    • Do not dispose in fire
    • Do not attempt to recharge
    • Keep away from children
    • Insert correctly
    • Do not mix fresh and partially discharged batteries

    PCT is a Russian GOST certification icon..
    Just like you would see the UL mark or CSA or VDE,etc...


    and transistor block because its a "block" shape and was first used on transistor radios..

    The icons should be self explanatory..

    The "Brazil only" statement is there because the package complies with all the laws of packaging materials, warnings and environmental statements unique to Brazil. Likely complies with local liability risks or packaging "norms" or advances for competitive reasons.

    At the same time, the battery chemistry may contain (or specifically not contain) components that are only allowed in Brazil (to give extra performance) or banned in Brazil (for safety of the user or environment).

    Even though several languages are used, they all say the same thing and are targeted at the foreign immigrants within the country of Brazil.
