No your battery needs replacing. I bet if you go out in morning and cold start patrol you won't start because dead battery has lost the surface charge Tony was talking about.

Your radio may be fryed inside as 36 volts through a 24 volt radio is not a good idea, worse if it's a 12v radio. The only way to prevent this for CB and UHF is to run fuses on both (-) & (+) feed wires to sets.
