Testing the TEC-06 battery discharge tester on a selection of 9V batteries
I have discovered secret settings and wonder what they are for. After powering up the TEC-06 while holding in the button, two numbers appear and can be fine adjusted up and down. The first number is 326 and the second is 5200. Any idea what these do? Enable calibration?
Thanks for the video. If you get a chance, I would like to see an explanation of the two modes shown in the usage instructions step 5 for "Start/Stop". It seems that "mode 1" is started in the "capacity" display state (first LED) and is meant for batteries or cells, and "mode 2" is started in the "voltage" display state (second LED) and is intended for power banks where no internal resistance measurement is desired. Did you ever do that video on internal resistance measurement? It seems the unit does a open circuit voltage check every few seconds and updates the milliohm reading.
Can this circuit test 18650 lithium battery resistance?
it is not linear, it is pwm…
Is it possible to set below 50mA load? I'm guessing not, but that'd be a nice feature.
Thanks for this, waiting for mine to arrive
If you could buy the God P battery for very cheap, it would be a good source of the half AAA sized batteries to use for replacements in solar garden lights, since each of those is around 68mAh that is basically what is in small solar garden lights.
Youmention the non-optimal position of the usb port. I agree, but the location of the fan in relation to the display and the rotary encoder bothers me slightly more. The fan will get in the way if you want to put the battery tester in an off the shelf enclosure. Oh, and thanks to the vid! Thumbs up!
I'd like to build one of these things except you would wire it up to your actual load in series with the battery and it would record the discharge current levels onto an EEPROM. Then, you could "play it back" with just the battery attached. I'm sure something like that exists already, but I think it would be a fun little project.
How do I calibrate this unit? I just bought one but mine is completely off with the voltage and the mAh is way too much. If I push in the button and power it up it seems to be in calibration mode but I dont know what to do there.
you can test 18650 with this right?
What cut-off voltage must one set for testing (discharging) AA NiMh batteries? At the moment I use cut-ff voltage of 0.9V (and discharge current 50mA) (these are the lowest possible settings on the TEC-06. Is this bad?
