* Note: Compatibility for chargers and batteries is guaranteed for all products manufactured from 2021 onwards (G2). Earlier productions (2019 & 2020 / G1 chargers and batteries) may experience compatibility issues with G3 chargers and batteries. This is due to, for example, software updates since 2019. This is common in electronics, where evolving standards can reduce backward compatibility. A well-known example is mobile applications (apps) that no longer function properly on older smartphones.
