I have been testing batteries using a 10ohm resistor and 2 multimeters-one to monitor voltage drop across the load, and another to monitor current .I could get by with one and figure the current from the voltage drop but I have the meters so why not use them?
Has anyone else done their own testing without a "proper" battery tester?
If so what do you use for a load and/or what criteria for good vs. bad.
I just don't want to spend $40 on a tester when I have instruments I can use right here.
