Rechargeable Goobay AA batteries are an economical and environmentally friendly solution when the built-in batteries in your shaver, hair clipper, or cordless phone have exceeded their charge cycles. Instead of replacing the entire device, you simply swap out the battery, thereby avoiding electronic waste and costs. These batteries are also known for their long service life. Goobay rechargeable batteries are particularly eco-friendly, as they can be recharged up to 1,000 times. They are ideal for industrial solutions as well as for use as replacement batteries in electric toys and small devices with built-in batteries. Rechargeable flat-top batteries with a flat positive terminal are also suitable for model building. The AA batteries weigh 111 g and are ready to use immediately thanks to the "Ready to Use" technology. Goobay HR6 batteries are especially environmentally friendly, as they can be recharged more than 500 times. Even after 12 months of non-use, the charge of the Mignon batteries still exceeds 70%. The rechargeable AA batteries are fast-charging and are characterized by high performance and longevity.
