Our Mission

Powering a Greener Future

The average household disposes of dozens of batteries each year. Most end up in landfill, leaching cadmium, lead, and lithium into soil and groundwater. We're here to change that — one charged cell at a time.

♻
Second Life, First Choice
A rechargeable battery can be charged hundreds of times. By buying a second-hand rechargeable instead of a new one, you save the energy and raw materials needed to manufacture a brand-new cell.
🌿
Fewer Batteries in Landfill
Single-use batteries account for a significant share of heavy-metal contamination in soil. Keeping rechargeable batteries in circulation reduces the pressure on collection and recycling systems.
🔍
Honest Testing
We don't just charge and hope for the best. Every battery is fully charged and visually inspected before listing. Batteries with visible damage, swelling, or leakage are safely disposed of — never sold.
📦
Packeta End-to-End
Both sell-in and delivery are handled via Packeta — a well-distributed parcel network across Central and Eastern Europe. Batteries travel from drawer to doorstep with minimal friction.

Proper Battery Disposal

Batteries that are too degraded to list are never thrown in household waste. They are deposited at official collection points or hazardous waste facilities in accordance with applicable law. If you're unsure how to dispose of old batteries near you, check with your local municipality or any major electronics retailer — they are legally required to accept used batteries free of charge.
