How to install batteries in old-style power supplies
All early radios used batteries—as many as three batteries in the earliest sets. These batteries were known as A, B, and C. Radio engineers soon designed circuits to eliminate the C battery in a typical radio circuit. That left two battery supplies, A and B. Rechargeable nickel-cadmium battery packs didn't exist in the "good. . Battery radios offer great bargains for modern collectors. Not everyone knows how to power them, so they often sell for less than their AC-powered counterparts. Many of them are still in. . For about $10, you can build a simple circuit that converts 120-volt AC household current into the DC current needed for a battery. . Adding this battery eliminator introduces a risk of shocks that was notpresent when the radio was powered only by batteries. Depending on which way youplug the cord into the wall, the radio. . The next photo shows the completed battery eliminator tucked into the old battery compartment in Walter's radio. The B supply is housed in the small blue box at lower right. It's a snug fit,. [pdf]
FAQS about How to install batteries in old-style power supplies
How do you install a 9v battery?
Hold the battery at a 30° angle and slide the connector side in first. Once you’ve lined up the snaps, tilt the 9V battery slightly. Push the top of the battery in until the snaps are touching, then press down on the battery so that it snaps into place. These types of batteries can be a little hard to install sometimes.
Can a battery be replaced with a power supply?
Say half an hour, then 24 V 24+ A supply. Replacing a battery from a battery-operated equipment with a power supply can be tricky. Especially when the equipment uses an electric motor. The problem is that an electric motor can draw very large startup current - it can be as 10-20 times the nominal for a couple of seconds.
How do you install a battery?
Insert the battery with the positive side facing up. Most devices that use coin or button batteries install them with the positive side facing up, unless they state otherwise. If you don’t see any markings on your device, it’s generally safe to assume that the positive side of the battery goes in face-up.
What type of battery should I use?
An alkaline battery (such as Duracell or Ever Ready Gold Seal) would be much better in this position since the voltage does not drop off as the battery ages to the same extent as normal zinc-carbon cells. I feel that the best approach is some sort of mains power supply.
What should I do if my battery portable stops working?
If your battery portable quits working, try replacing the A battery before the B battery. Many battery-powered tube radios require only 1.5 volts for the A supply, which you can provide with ordinary 1.5-volt "D" cells (flashlight batteries). If more than 1.5 volts are needed, connect additional batteries in series.
How much does a battery radio battery supply cost?
Although simple to construct, this battery supply will not last long and you will still have the problem of disposal. For about $10, you can build a simple circuit that converts 120-volt AC household current into the DC current needed for a battery radio's B supply.
