A power supply such as PR48 has an analogue of the DA13 type, ZA13, AC13. They're essentially the same thing. Before purchasing, make sure the battery is compatible with your device. It's shaped like a metallic disc with a distinctive sheen.
The positive pole usually occupies a larger area, while the negative pole is much smaller. The dimensions of this current source are as follows:
- Height: 5.4 mm.
- Diameter: 7.9 mm
It weighs about 0.4 grams. Its voltage fluctuates between 1.4-1.45 volts. This is quite enough to to power an electric hearing aid.
Form factor R-48. Electrolyte type: air-zinc. Supplied in plastic-coated cardboard packaging. Typically in quantities of 6.
Manufacturers produce only high-quality PR48 batteries. They fully comply with ISO9001 and ISO14001 standards.
To start the energy storage device, you need to remove the special shutter and wait about five minutes. The element operates on oxygen, so it must be allowed to enter. The capacity of these power sources is much higher than that of silver-zinc and alkaline cells. They maintain a constant voltage throughout their entire service life. They do drain quickly.
