Description
Varta to CR2032
Replace old leaking Varta 3.6V NiCd batteries in old computers and other retro devices that used them for battery backup.
This pcb uses a vertical CR2032 battery socket and
- 1n5711 schottky diode (low reverse leakage current)
- LM66100 ideal diode (two silicon parts for safety redundancy)
This prevents the motherboard from trying to charge the battery, allowing the battery to provide backup power to retain settings.
Depending on the motherboard, the battery may or may not also be able to properly retain the clock/calendar settings, but retaining CMOS configuration at least can be very helpful on some motherboards when using them for a while and not wanting to re-enter the configuration on every cold boot.
