Battery leak: is it toxic? This is what you should do

A battery leak can occur in almost any electronic device. In this practical tip, we explain whether this is toxic and how you should react in such a case.

Is the liquid in a battery toxic?

When a battery leaks, this is usually indicated by white deposits in the battery compartment of the electrical appliance. However, the leaking liquid does not pose a serious hazard.

• When a battery leaks, it is usually electrolytes that leak out – slightly caustic acids or bases.

• Although they may sting a little on contact with the skin, they are not seriously toxic. If you touch the liquid, you can simply wash your hands thoroughly.

• The same applies to clothing: if it comes into contact with battery fluid, a normal wash is enough to remove the stains.

Battery has leaked: This is how you should act

Proceed as follows:

• As soon as batteries are deformed or leak, you should replace them and dispose of them properly. Otherwise, the device may be damaged.

• You can put on ordinary household gloves to remove the batteries. This will help you avoid direct skin contact. If batteries have leaked in a device, it does not necessarily mean that the device is defective. Often a simple cleaning is enough and you can continue to use it.

• A cloth with lukewarm water is usually sufficient for cleaning. Wipe the white deposits inside the device with it.

• If battery acid has settled on the metallic contacts, water alone may not be sufficient. In this case, you can add a little vinegar or special alcohol for cleaning.

• To clean hard-to-reach places, you can use cotton swabs or a toothbrush.
