An anode battery is a chemical current source used to power the anode circuits of a self-powered lamp radio equipment. It is a battery of series-connected galvanic cells (usually manganese-zinc ) with a total emf of several tens to one hundred or more volts . Typically, such a battery had three conclusions: two from the extreme poles and the third from a part of the elements. This made it possible to use part of the battery, and when its EMF decreases markedly - to connect the entire battery, together with the remaining fresh elements, and thus extend the battery life. In addition, shielding nets of tetrodes and pentodes could be fed from the tap. Often, the anode battery was structurally combined with a power source for the filament circuit (anode-filament battery) or bias voltage (anode-grid battery). Despite the fact that battery-operated tube equipment around the world is almost out of use, anode batteries are produced by the Russian industry so far for use for other purposes [1] . Below are the characteristics of some anode batteries produced in the USSR.
| Name | EMF, V | Initial capacity, Ah | Appointment |
|---|---|---|---|
| 31-SAMCCH-0.02 (GBCH-SA-30, “Rumor”) | 31 | 0.02 | For hearing aids |
| 65-ANMTS-1,3p ("Tula") | 65 (anode) 2.5 (glow) | 1.3 29.5 | For broadcast receivers |
| 70-АМЦГ-5 (BS-G-70, "Friendship") | 70 | five | Also |
| 68-AMC-X-0.6 (BAS-60-X-0.6) | 68 | 0.6 | For broadcast receivers and communication equipment |
| 87-PMTSG-0.15 (GB-80) | 87 | 0.15 | For receivers and dosimetry equipment |
| 102-AMC-U-1,0 (BAS-80-U-1,0) | 102 | 1,0 | For broadcast receivers and communication equipment |
| 120-AMTSG-0.27 (BAS-G-120) | 120 | 0.27 | For broadcast receivers and communication equipment |
In addition to dry anode batteries (ALS), ready for use, until the 1930s - early 1940s. “wet” (BAM) were also produced, which worked with liquid electrolyte . Before use, their elements had to be filled with water. Radio fans successfully made “wet” batteries themselves.
