The fact that 25V supply is dropping to 23.4V shows it is drawing far more
current than it is rated. I am assuming this is a regulated power supply.
Does the power brick actually shuts down at 500mA or does it let the the
voltage drop and try to supply what it can? Maybe one or more Nicad
Hi
I would dump the batteries. If you need backup, run a UPS or some sort of
external DC setup. Batteries inside something like the 105 only seem to
lead to messy problems down the road.

Hi All:
A 105B (quartz oscillator) is blowing the 1A fuse, after it is on about 1 hour.
The fuse appears to have just melted (not a black mark as the result of a
flash, in the case of a high current short.)… just looks like the fuse wire
(inside the glass capsule) melted into some little blobs,
I have a bunch of these chips, and log everything I can think of.
I use the BME280 connected to an Arduino ESP8266 (that has WiFi)
The setup itself has no clock. It wakes from sleep, takes a temp, connects to
Wifi, sends a JSON string to a server, then sleeps.
The server logs the time.

I just used a Raspberry Pi, and interrogated the values over SNMP:
