West Mountain Radio Computer Battery tester.

Hi,

I just got my CBA II testing my first battery today, and was very interesting to see the way my 12V 12A hour battery discharged. I noticed a pattern like a stair step. Which got me to thinking why does not the energy come out of the battery at a constant rate? What in the chemical process is making it do this? or something else?


Anyhow, I was thinking about hooking it up directly to the charging side of the SSG to measure the rate the battery was charged. I was wondering if there would be the same stair step effect as on the discharge...... But I was afraid that I might kill the tester with the direct spike from the ssg.

Another idea hit me that I could put a capactior on a dpdt switch that I then could swap back and forth between the tester and the load of the SSG.
This should give me an accurate measurement of the rate the battery charges and all of the inbetween jumps ...


Any thoughts on this?

i would surmise a dpdt switch that could handle the voltage and current of the ssg and the analyzer would work. looks like a nice analyzer ,i checked specs and it looks like a good one,many features . i have a simple load tester ,nothing special ,i went for analog load tester because the digital one's relay stuck within a few days .i do not own an advanced analyzer as this one you have but (my opinion only) should work. btw project i was working on was successful and i will email details soon also movie is almost done should be where you suggested in a couple days as well as google and maybe metacafe
yay!

Modified test with the CBA on SSG

Interesting comparing meters when testing....

I believe I am not getting the true amount of amps with my amp tester...
