What you have going on is the classic "weak link in the chain" battery
problem. One cell has less capacity than the others, and once it is
exhausted (at 360 mA load), the voltage across it collapses and then
reverses (reverse charge). Thus the drop to about 3 volts.
Charging can be thought
Ed,
I'm aware of the typical C/10 rating for Lead Acid batteries. However,
many NiMH cells are rated at higher discharge rates.
Problem is, my cells are unmarked; so I'm somewhat in the dark. Even
after I opened the blister pack; I couldn't find any manufacturer's
markings.
I may have to get a

Hi all,
I have a question for you not specifically related to EMC; but I hope that I
can “hijack” the group’s attention for another sort of problem.
Recently, I’ve been allowed to do some non-compliance design work.
Specifically, I’m working on a battery charger/power supply design.

We purchase a supply that indicates compliance with EN61000-3-2 harmonics.

All,
I finally found the R&O for the antenna rule change I referred to. Here it
is...

The change to 15.204 is about 1/2 to 2/3 of the way through the document.
