As a rule, you can recycle batteries and accumulators at stores that sell them and at regional collection points, which you can find at kierratys.info.
Remember these:
Tape the terminals of batteries and accumulators.
Reduce the risk of fire by covering the terminals of discarded batteries and accumulators with tape. Place leaking batteries and accumulators in a bag. Read more about how to handle batteries and accumulators safely here.
Take them where you bought them.
As a rule, you can return all batteries and small accumulators free of charge and without an obligation to purchase new ones to any store that sells them.
What can you return to stores?
- alkaline batteries (disposable standard batteries: e.g. AA and AAA cylindrical batteries, button cell batteries and 9V rectangular batteries)
- lithium batteries (disposable standard batteries: e.g. AA cylindrical batteries and 9V rectangular batteries)
- button cell batteries
- nickel-metal hybrid batteries (rechargeable batteries and accumulators, e.g. for cordless tools)
- nickel-cadmium batteries (e.g. for cordless tools)
- small lithium batteries (e.g. for mobile phones, laptops, power banks, cameras and cordless tools)
- small sealed lead gel accumulators (e.g. UPS, solar cell or alarm systems)

- Lead-based batteries, such as the starter batteries of cars, motorcycles, mopeds and other vehicles, lead-based industrial batteries and boat batteries. You can tell a lead-acid battery from other batteries by the Pb label on it and its heavy weight. All lead-acid batteries can be put in a collection container for lead-acid batteries, if one is available at the collection point. In the absence of a separate container, portable lead-acid batteries can be placed in the Paristokierrätys barrel and larger ones can be deposited at the collection points specified in the kierratys.info search service.
No batteries or accumulators must be disposed of with mixed waste. 
This is indicated by the separate collection symbol on the batteries and accumulators or their package.
