He said unequal voltage. In which case he's right.
Capacity is not voltage.-


How to properly analyze the problem:http://www.electronics-tutorials.ws/...its/dcp_4.html

Look at Example 1.

Thank you Jim. I was sitting here wishing I could draw
a simple circuit into the newsgroup that models what we
are talking about and shows what really happens.
You've gone one better and found a perfect example
from an independent and credible source. That
circuit is EXACTLY the model for the dual battery
example I brought up. Each battery is modeled as
an ideal voltage source in series with a resistor. And
each supplies part of the current flowing through
the load. One never charges the other, nor does
one need to have a higher voltage to "push" current.

I suspect we'll be hearing soon from Homeguy
about how this isn't a valid way two batteries connected
in parallel to a load can be modeled.
