Hello there and welcome to my video. In today's video, I'll be making myself a little tool that I believe every computer technician should have. CMOS batteries go bad all the time and need to be tested very often when working on computers. But, testing these batteries using a multimeter is cumbersome and awkward, so I've decided to build a DIY CMOS battery tester today!

You are right. 3d printing, custom pcb, soldering, arduino coding, all of that is so much simpler and easier than just using the multimeter. Loved that you had to use a multimeter to calibrate it :)) irony was exquisite
Awesome idea. Though my fat fingers struggle pulling the batt out of the socket. But way better than a multimeter
I am not disrespecting the author for his work - great. but for those that do not want to build a cpu based solution and have to do coding, how about this - take a battery holder for the 5 vold motherboard battery - glue to lucite. take 2 of somthing ( I think the standoffs for motherboards with screws ) and put into the lucite. Wire battery adapter to the standoffs. ( use screws or solder to hold the wires to standoffs ). Now you can put battery into holder and lay lucite board down an use multimeter to check battery ( no holding - problem solved ). You might have to add the resister to the circuit as author stated.
Certainly a way to do it if you don't want to do the screen and Arduino thing, thanks for sharing!
Or just put battery +ve side down. Hold down battery with negative probe, positive probe on the side... amost like you did at 10:05
Probably the better method for a lot of people!
I love your Tinkery attitude towards such problems. You *could* go out and buy a tester like the one you showed in the video. But you chose the option which is harder, and more expensive! I will say though, I would totally buy that device if you ever sold a v2 of it!
probably should've used a gpio to toggle the load to prevent draining the battery too much...
Definitely a good idea for a revision, thanks!
Love it
Could it be that the wrong measurement of the empty battery is due to some current sourced by your device into the relatively high impedance battery? You should measure the voltage across the battery terminals with no battery in and check if it is pulled towards 3.3V
Great idea, that did cross my mind while I was troubleshooting even though I didn't mention it. There wasn't any voltage coming from the Arduino. but definitely a worthwhile check!
