How to make 1.5V battery tester

The measured voltage can be changed by changing the series resistance of the voltmeter.
For accurate test, load resistor must be connected.(50~100ohm)
It can be conveniently used in places where batteries are used in large quantities.

NIce video, great system 👍

It's always a pleasure to watch your videos. You make everything seem easy :)

video intelligente , bravo ! j'ai un voltmetre 0-150 v dc et je n'ai pas compris votre raisonnement pour l'adaptation des resistance!! dois -je diviser par deux votre exemple pour que cela fonctionne ? merciiiiiii--------clever video, well done! I have a 0-150 v dc voltmeter and I did not understand your reasoning for the adaptation of the resistors!! do I have to halve your example to make it work? thank you

In general, what is a good current load to check a 1.5v alkaline battery? 20mA?

Напряжение, желательно, мерить под нагрузкой. Поставить нагрузочный резистор. Не увидел его в ролике.
