You can return your old batteries at various institutions or organizations to potentially receive cash back. Here are some places where you can try to hand in your old batteries for money:

1. Battery collection points: Many supermarkets, electronics stores, or recycling centers have collection points for old batteries and accumulators. Although you may not receive direct payment, you contribute to sustainable waste management.

2. Manufacturers' take-back programs: Some manufacturers of batteries or electronic devices offer take-back programs where you can return your old batteries and potentially receive compensation. Contact the manufacturer of your battery to inquire about such programs.

3. Scrap or recycling companies: You can contact local scrap or recycling companies to ask if they are interested in buying old batteries. These companies can extract and reuse the valuable materials in the batteries.

It is important to note that the financial value of old batteries is usually relatively low and can vary depending on the type of battery and the current market prices for materials. Furthermore, there may be local regulations and requirements regarding the processing of batteries. Contact the relevant authorities or recycling companies in your area to inquire about the specific options for handing in old batteries and whether compensation is available.
