After Seeing Jim Frye's thread " https://www.sawdustzone.org/forum/di...ging-batteries ", I have been thinking about mine. I do have some that are about 12 -13 years old and a few do seem to have a shorter life than others, even though I don't notice it on my impact driver or cordless drill because I only use them for a few minutes at a time. But on things like my 12" chain saw or weed eater or a couple of other 18V tools, they are short lived but IF I put one of my newer batteries of the last 2 or 3 years, I get much more work done.
So the question is: How does one test a multi-cell lithium ion battery to know its real world viability?
I asked this question on Google, but it brought up people with volt meters that tests only the charge on a single cell. Not exactly what I was looking for.
One other thread said to take them apart and measure them a week after being charged! Again, not what I need.
Is there anything, way or instrument that will tell me the viability of the 18V battery as a whole? I would like to see the potential left in the whole battery. Something like an automotive battery load tester.
Thanks
