Battery acid counter balance for longevity

  1. I collect branded goods and came across this old Energiser battery which had been left at one of those communal recycle collection points in our local supermarket, what a find, it's the old ones that I remember from my childhood and labelled as "Made in Britain" (my God, that must have been some time ago!).

    Anyway, I managed to peel off the outer logo to discard the batter as it had been foaming and wanted to know how to treat it so that it wouldn't dissolve over time. I know to keep it in an air tight container and out of direct sunlight, but I'd like to counter the effect of the Alkaline from the broken battery.

    I suppose the first step would be to test this, perhaps using this: http://www.ebay.co.uk/itm/100-STRIP...t=UK_Health_HealthCare_RL&hash=item3f27a345f8

    Then make a solution from ..lemon? and dilute it as necessary... apply it with a cotton bud and wash it with water and it should be okay, yes?

    I am not convinced you will be able to stop the process without destroying the battery, but it is not clear to me what you are trying to save.

    The only way of slowing the reaction is to keep the battery in as dry place as possible.
     
  4. Battery wrapper

    Sorry, I meant the branding, the film on wrapping the battery. I have since disposed of the battery itself, but wanted to preserve the film:

    Sorry for the misunderstanding, thanks!

    It is some kind of plastic foil? I would just wash it with a copious amounts of tap water, perhaps followed with a wash in DI water. Any other approach means you are introducing more compounds that are not necessarily inert.

  6. Well I thought about using the pH paper to tell, but the part I test it on might not be uniform, so it could do more damage than good?

    Not sure what DI water is please?

    It's also called 'deionized water', water which has all dissolved ions removed from it:

    As SteamKing explained, DI means deionized. It is just one of many ways of naming water that was purified by any means.

    You can use pH paper to test pH of tap water in which the foil is washed, to make sure bath is neutral after wash. To be exact, it won't be exactly neutral, as tap water rarely is. Even DI water won't be neutral, it will typically have pH somewhere around 5.6 due to dissolved carbon dioxide.
     
  9. But for my purposes it should be fine?

    I'm looking to archive the plastic cover.

    I can't think of anything substantially better. Could be those professionally involved in conservation and preservation of antiques/collectibles know better ways of dealing with such a foil. I am not one of them, but I am also reasonably sure water will remove base - and the foil itself was designed to be reasonably resistant, so some water can't be dangerous.
