Alperator Posted September 29, 2018 Share Posted September 29, 2018 The power supply for the Torn. E. b is done by a collector 2B38. Since these batteries don't supply electricity after almost 80 years, I converted it to a new rechargeable battery. The collector is cut open from behind with a fine saw, the lead plates with connections are cut out, cleaned and the new battery is connected with the old connections. The new battery (2 Volt 10 Ah) is charged via the connections + and - from the collector 2B38 with a standard charger. greetings http://der-fernmelder.de/ 1 1 Link to comment Share on other sites More sharing options...

Have you tested how long your Torn.E.b works with this battery? Link to comment Share on other sites More sharing options...
Alperator Posted September 29, 2018 Author Share Posted September 29, 2018 Long-term test is still pending, I charge the battery fully and test the runtime. 1 Link to comment Share on other sites More sharing options...
