Sometimes the battery shows same voltage(12volt),but still its faulty.This is because battery getting old.A basic life of car battery is approx 2 to 4 years.Its not that it will not perform after 4 years but mostly these batteries are to be replaced,to make your vehicles electrical system upto mark.

Regarding replacing car batteries i will say.Always buy branded batteries if possible.Why because local aftermarket batteries are made up of weak internal cells.Cells are inside the battery,which actually hold the charge.If the cells are weak,then battery will not remain charged or loose its charge in few hours.

A branded battery is bit costly,but you will really enjoy its performance.Also if in case a new brand original battery gets faulty,you have warranty on it.So there is no risk of investing in original genuine battery product.
As compared to aftermaket local batteries,they don't come with warranty and there is just few months guaranty provided.
Some times these aftermarket low cost batteries don't get completely faulty,but there performance will be very weak or it will not support your vehicles system.

In this case first thing to be checked is car alternator and battery.
Load test the battery and see if its checking ok,Bench test the battery and alternator and confirm both are good.

Also see if any lights inside or outside the car is not turning off after you turn the key off.
If any light is remaining ON,that there is your problem.

But if all things checks out ok,then its issue with radio.

As long as the alternator is charging ok (14.0 volts) and the battery load test passes is the radio on the 2002.
Try pulling the #31 radio fuse and see if the draw goes away.
If it goes away,then yes problem is with car radio.The radio has to be replaced,before that without forget,inspect the car radio wiring.If all wires are checked intact,then radio has to be replaced,its draining your car battery.This problem is very much noticed on 2000 to 2003 ford focus car models and issue is with car radio,causing this.

So without forget,first confirm the other possibilities,if all checked out ok,then yes its issue with car rtadio causing this problem.

This will help.

Thanks.
