N9mxq - I don't need guess work I would like to hear an answer from UPMAN.
Jaspence - more guess work and if you read my post you will know the answer to you Q.
Marksmith - same as above.
KK4JUG - I am not confused. I understand voltage and current very well thank you.
My question should have been more like this: Does the 436 limit or control the input voltage from the battery's or does it just take the .3.6 - 3.7 volts supplied by the battery's?? If yes, what is the maximum voltage we can supply?
Really? Really? I didn't know that you guys designed this radio, If only I would have known that, I could have saved some time and asked you all. Since you are the experts you should be able to answer this question. What is the maximum input voltage the 436 can handle? And answer that for the bcd325p2.
And don't give me your guess. Anyone can guess. I can guess.
gonefishn1, I answered from 50 years experience building electronic kits and doing computer and radio repair. I guess I should have been more blunt and told you it was a stupid idea and would lead to the predictions of the other honest answers.
It's designed run on USB power or 3 AAA batteries. The compartment was designed for 3 AAA batteries. They furnish you with 3 AAA batteries. If anything else was possible, someone, including Uniden, would be selling it. Get the chip off your shoulder.
jaspence - I apologize, I'm sorry I didn't know that your an expert in electronics. I should just listen to you instead of the engineers and designers of the radio. Oh, you didn't answer my question. I'm sorry again.
Silly me for wanting to know the answer.
No, the 436 doesn't have a built in over voltage protection circuit. Approximately 5.5 volts is the max. Any thing over and your scanner will do a fry. Depending on the amount of over voltage how fast the fry will occur. There's a reverse voltage diode, but it will not protect from too much voltage coming in.
Two 3.7 vdc (?) equals ~7.4 volts.
