Most lithium small radio batteries are 3.6 volts. If AA or AAA batteries, multiply by 1.5 volts. 4 batteries = 1.5 * 4 = 6 volts MAXIMUM. Rechargeable batteries are 1.2 volts. Your charger would be a much higher voltage because it takes power to "push" the charge into a battery. You didn't say, so I am assuming you want to operate the radio with a wall charger. I've done this by soldering the wires to the battery contacts. You need a higher voltage than 3.6 volts, but milliamps is more important. You need enough milli amps to get the radio to transmit. Too much and it frys, literally. So, this is all on you to decide if the risk is worth it. I use a 5-6 volt power supply set on no more than 1 amp (800 ma is my favorite size) 1 amp = 1000 ma. Let us know if this helped!
You would need to have a stable 12 volt DC power supply that plugs into a 120 VAC outlet. You can google these, and they come in quite a few varieties. The most expensive are the variable voltage "lab grade" ones, then the bench grade fixed voltage variety, and then the cheap consumer grade 12 volt 1 or 2 amp device designed for CB's and small 12 volt devices. But this will not work, because you are transmitting and could be putting out 40 or 50 watts with that thing. So you will need a good 10 amp to 20 amp dedicated transceiver power supply, unless you just plan on receiving in which case you only need a couple of amps and the cheapie will do. It's always better to have more amperage in a power supply. You then need to think about issues like back-up power with a gel cell 12 volt battery, which also would allow you to use the cheapie supply, because you would have plenty of current to XMIT from the battery. Schematic shows a very basic 12v - 30 amp supply. Good luck!
It is very possible that one of your batteries might be dead from the factory. Just because the product is new, does not mean that it will work. Errors in production of products, does happen. Take the battery from the working radio and try it in the radio that does not turn on. If it does not turn on then you have proven that the radio is the problem. If it turns out that the battery is dead, you still might be able to revive it.
I have seen this battery problem happen quite often. If you have a 12vdc power supply. Try zapping the battery with the power supply. What I mean is, connect the negative from the power supply to the negative on the battery and then Connect a second wire to the positive on the power supply and just touch the other end of that wire to the positive side of the battery just momentarily. Check the output voltage from the battery. If the battery now shows a voltage reading, you can now try charging the battery with the charger for your radio. it there is no voltage on the battery I would say that it is dead from the factory and would get the seller to exchange it. If you do not have a power supply, a local radio shop might be nice enough to zap the battery for you.
your device should be marked with polarity and voltage requirements. Any power supply with the correct plug meeting those specs (if amperage isn't marked, look for one that is between 500- 1000 mA) should be fine. MAKE SURE it is a DC supply if the device you are using is marked DC.
