Batteries are used to generate power for portable devices such as calculators, watches, remote controls, flashlights, electronic instruments, etc. These make the operation of these devices possible, thanks to the fact that the chemical energy is converted into electrical energy, thus maintaining a constant potential difference and generating a small voltage. However, when the useful life of a battery ends, it becomes waste that, if not properly managed and disposed of in household garbage, becomes a threat to the environment since the metals that compose it are highly toxic.
If you want to know how long the batteries take to decompose or what to do with the used batteries so that they do not contaminate, be sure to read this interesting article by Green Ecologist where it will be explained in detail from how long does it take for a battery to degrade to its impact on the environment, how it is recycled and what is done with recycled batteries.
It is estimated that the battery degradation time is understood between 500 and 1000 years, once these begin to decompose, the protective layer that covers all the heavy metals that make up the batteries first degrades, and later these metals are released being very toxic and dangerous for the environment and all types of life that are part of he.
Some of the metals that can be found in the composition of batteries are lead, chromium, mercury, zinc, arsenic, cadmium, among others. The most polluting metal is the Mercury.
The battery degradation in household garbage, or in natural environments, has as a consequence great impacts for the environment:

There are many types and varieties of batteries that can be found, but they all have in common that a large part of the materials that compose them are heavy metals. These metals are toxic to any kind of life and for the environment.
This is why a good management and recycling of them will prevent environmental deterioration, as well as stop being a danger to living beings.
After the life of a battery has expired, it is cannot be disposed of in household garbage, but will have to be deposited in a specific container for batteries or take her to a clean point and, later, they will be managed according to their typology and recycled. Clean points can be found both in towns and cities and specific containers are very common in some businesses such as pharmacies, supermarkets, etc.
We encourage you to read this other post on What to do with used batteries so that they do not pollute.
To avoid battery contamination, these must be recycled. Once the batteries arrive at the recycling plant, there are different processes to do so, but in general all of them are based on the separation of the metals and the rest of the materials that make up the batteries. In this way, they end up obtaining pure metals that can be used for the manufacture of new batteries.
For example, in the recycling an alkaline battery, which is one of the most used, are separated:
