Usually, radios have a slot at the back or bottom where you can insert batteries (Often AA). If it does not have a slot, and isn't solar powered or anything, then contact the radio manufacturer, who will tell you how to use batteries.
If the radio has to be plugged into a socket outlet and has no slots for any batteries, then the only way you can use batteries to supply it with power is to use an electronic power inverter unit. Several types are available. The most common can use a 12 volt battery and has a socket outlet into which you can plug the radio.

Does a battery have a recharge memory?
The NiCad or nickel cadmiun battery develops a "memory" of its duty cycle (called - surprise! - "memory effect") if it is used in a "pattern" for a while. If, say, a 2-way radio is used only a few minutes a day over a number of days and then put back on a charger after each use, it will "remember" this. If an attempt is made to use the radio for more time, the batteries just "drop dead" and the radio is unusable.
