Rechargeable Goobay AAA batteries are an economical and environmentally friendly solution when the built-in batteries in shavers, hair clippers, or cordless phones have exceeded their charging cycles. Instead of replacing the entire device, you simply swap out the battery, thus avoiding electronic waste and costs. The batteries are also characterized by 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 applications as well as for use as replacement batteries in electric toys, cordless phones, and small devices with built-in batteries. Rechargeable flat-top batteries with a flat positive terminal are also suitable for model building. The AAA batteries weigh 36.5 g and are ready to use immediately thanks to the "Ready to Use" technology. Goobay HR03 type rechargeable batteries are especially environmentally friendly, as they can be recharged more than 500 times. The charge of the micro batteries remains over 70% even after 12 months of non-use. The rechargeable AAA batteries are fast-charging and are distinguished by their high performance and long lifespan.
