The repairers cam modify the G1 PCBs to fit the latest CR2450 battery and holders.?
Also developed an¡±ideal or diode ¡° modification that removed Dual Schottky ¡±D1¡±and replace it with LM66200. ?This is a more modern switching device made for 5V/3v battery back up systems. ?It¡¯s drops far less power than ¡°D1¡± indeed tested SRAM is kept ok, down to 2.3V (possibly lower).?
It¡¯s just putting a more modern switch in the cct that probably would be done if they had been available when designed. ? It¡¯s just ¡°ideal or diodes¡± are a more modern efficient (less losses) method of using 3 or 5V and switching 3V battery backup power switching. ?
This should give as good if not longer battery life to any G1 as compared to a G2,
This is early trial. ?The LM66200 is tiny pin pitch ~1.1mm. Hell to solder in but works beaut.?
FWIW.?
