Plug a booster pack or car charger with a power point adapter into the power point (cigar lighter) of you vehicle before disconnecting the battery. This will keep power to your radio and security system. The bonus is it will even save you radio presets.
You will loose your radio presets and clock time. You will have to reset the clock and radio presets and that is all.
No, all you need to reset is the clock and radio presets.
Yes; pilots have to be able to use the radio without the engine running and most engines have electric starters so batteries are essential.
The batteries in a portable radio can be recharged you must buy rechargable batteries and a rechargable plug that you can charge them with the are great to have and save lots of money.
AC - Alternating Current, same thing that comes out of a wall socket DC - Direct Current, batteries. <<>> When a device has AC/DC on its name plate, it can work off either of the two voltages. Many portable radios have this function. When the radio is plugged into AC, the voltage is transformed to the working DC voltage and then rectified to a DC voltage. When the radio is on battery operation, the radio operated strictly from the DC voltage supplied by the batteries. The change between voltages from AC to DC or DC to AC is almost instantaneously. This change over is done through an AC powered relay in the radio. When the AC held in relay looses its supply it de energizes and switches over to DC power if the batteries are in the radio. With batteries in the radio try it. Plug into the AC supply, turn on the radio that has batteries installed in it, unplug the AC supply and the radio will not miss a beat.

Put batteries into a radio then press the on button
You can power your DC toys with the AC power plugs in the house. Like a Radio without using batteries.
A radio that gets power from batteries instead of the outlet on the wall.

Many or most two-way radios run on AA or AAA batteries. This depends upon when and where the radio was purchased, how many watts the radio has, and the development of rechargeable batteries; it may be worthwhile to purchase rechargeable AA or AAA batteries.
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.
