Dealing with corrosion from mercury batteries :
Upon inspection there was no battery inside but the battery door has some slight green corrosion from the (old) mercury battery. Just the lid, it doesn''t look too bad, but I also want to take (my health) seriously. Do you think I will be fine taking it outside, wearing gloves, a mask and glasses to clean the battery pad with some vinegar?

6 FAQs about [What are the mercury batteries ]
What is a mercury battery?
A mercury battery (also called mercuric oxide battery, mercury cell, button cell, or Ruben-Mallory) is a non-rechargeable electrochemical battery, a primary cell. Mercury batteries use a reaction between mercuric oxide and zinc electrodes in an alkaline electrolyte.
What is a mercury cell?
The mercury cell, also called “mercury battery, mercury oxide battery”, is a primary cell, which is a non-rechargeable, non-reusable electrochemical battery.
How many volts is a mercury battery?
The voltage during discharge remains practically constant at 1.35 volts, and the capacity is much greater than that of a similarly sized zinc-carbon battery. Mercury batteries were used in the shape of button cells for watches, hearing aids, cameras and calculators, and in larger forms for other applications.
Why do button cell batteries contain mercury?
Build-up of hydrogen gas can cause the battery to leak, limiting the ability of the battery to function. Mercury suppresses this zinc corrosion, which is why it is added to button-cell batteries. These batteries may contain mercury in the insulating paper surrounding the battery, or mercury may be mixed in the anode itself.
What are the different types of mercuric oxide battery?
There are mainly two types of mercuric oxide battery – one zinc mercuric oxide battery and two cadmium mercuric oxide battery. Environmental problems are also associated with cadmium. The market of this battery has been occupied by alkaline manganese dioxide, zinc-air, silver oxide and lithium battery. It has very high energy density.
How does a mercuric battery work?
Mercury batteries use a reaction between mercuric oxide and zinc electrodes in an alkaline electrolyte. The voltage during discharge remains practically constant at 1.35 volts, and the capacity is much greater than that of a similarly sized zinc-carbon battery.
