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?
