What can I do to maximize battery life and protect my radio warranty?

Turn your radio off before charging, use only genuine Hytera chargers and batteries, and replace the battery if you notice a clear drop in runtime (many teams plan replacement around the 2-year mark). Using non-approved batteries can damage your radio and void the warranty.
