Quote from: countryman on November 26, 2022, 07:28:47 AMIt seems rechargeable alkaline batteries are still in use, yet uncommon:https://en.wikipedia.org/wiki/Rechargeable_alkaline_batteryApparently they are not suitable for high current applications, where NiCd, NiMh or Li-Ion cells must be used.It is known that also regular alkaline batteries may be "refreshed" at low current rates and that is what supposedly happens in the phone - the battery only has to give off a relatively low current for limited time, and then is recharged at low rate for long time. Maybe 8 normal 1.5 Volt alkaline cells will last long ways in the application?Good luck with the restoration - metering pulses are a tough challenge, be it those 50 Hz pulses or 12 or 16 kHz like in other countries.
