As of my last knowledge update in October 2023, lead-acid batteries, including G-Wiz batteries, have a high recyclability rate in both Europe and the US, typically around 95% in Europe. The European Union has stringent regulations that promote the recycling of lead-acid batteries, ensuring that a significant portion of materials is recovered and reused. In the US, recycling rates are also high, though they may vary by state and local regulations. Overall, lead-acid battery recycling is well-established in both regions.
