Is there a reason why battery manufacturers can get away with describing their products as long life, extra long life, super, best ever. These are meaningless, battery’s have measurable capacities in mA. You would not expect to buy any other measurable product in this way

    mAh.  mA is not a measure of capacity.

    They "get away with it" precisely because the terms you give as examples are all relative so as much as they are meaningless, they're also not incorrect.

    Plenty of other measurable products are sold that way.  S/M/L/XL on clothes, for example.  None of those sizes is universally defined but the items themselves are measurable (and measurements are often stated alongside the sizing).  Broadband is another, with providers using terms like "superfast", "extreme", "lightning fast" to describe enormous variations in maximum speeds when typical speeds might be nowhere near them.

    Absolutely you do... many things have mesurable and yet they are sold on marketing slogans instead. Tesla, and other EVs, do a "Long Range" and "Performance" versions but they are all terms relative to the base model.  Matches (length), torches (brightness), clothing (size), flour (protein level), shoes (width) etc 

    Getting words like "Extra" into the name is emotive and influences customer behaviour... long list of numbers tend to be a turn off

    “Which” have done extensive tests on batteries.  Some are better than others.  How long they last is often related to price but that’s not guaranteed.  The very cheapest are often rubbish.  I bought some in IKEA once, they were ridiculously cheap and lasted a ridiculously short length of time.  

    If I want advice/help on batteries I’ll ask my house mate.  He worked as a technician for Ever Ready for donkeys years  :)

    Also what they are used in makes a difference.
    Blink Camera's
    Use Alkaline can be looking at months at best, use lithium & it can be up to 2 years. All depending on usage.

    Not in my experience.  Keep it in the fridge and it lasts for ages.
    If it sticks, force it.
    If it breaks, well it wasn't working right anyway.

    I use rechargeable ones, which do have the capacity listed online - but given it costs so little to recharge them, it's hardly a big deal. If you're annoyed about battery capacity often, you probably use enough to warrant splashing out on the initial cost of a charger and a stack of rechargeable ones. Both eco friendly and money saving!
