Testing batteries with multimeter
bc888:
I recall Dave Jones doing a You Tube on how to charge batteries with a Power Supply Unit, but don't recall if he detailed discharging or measuring with a multimeter first, you might do a search on Daves videos. To add to the subject, there are battery chargers that will first fully discharge and then charge batteries if you need an accurate number. Folks doing laptop pulls to reuse old 18650 lithium for example. Litokala 500S comes to mind. HKJ has some great info on his web site.

Clicking first on the chart you want, then you can click the header to sort for what you are looking for. He lists the 500 but not the more recently released 500S. https://lygte-info.dk/info/roundCellChargerIndex%20UK.html
If you sort by "analyzer" you get the discharge current he measured. Quite a remarkable amount of good information. Link https://lygte-info.dk/info/roundCellChargerIndex%20Analyzer%20UK.html
