When I READ the paragraph BEFORE your comment, it MADE perfect sense
to ME. Charging in SERIES is best done when the batteries are EQUAL in
BRAND, type and STATE of CHARGE.

I'd be WILLING to charge BATTERIES in PARALLEL since they all end up
at the SAME VOLTAGE.

No. If the batteries aren't the same size or the same level of
discharge
the strongest battery will take most of the charge. This is similar
to
memory effect in NiCad. Don't put them in series unless the batteries
are even, which is unlikely outside a device that needs three.

Actually you have it WRONG. Batteries are ALWAYS charged in series

If you think a little harder about it, he is correct. A single 12v
wet cell battery is comprosed of six 2 volt cells in series.

The conclusion you jumped to was that it's desirable not to charge
several independent 6 or 12 volt batteries in series unless they are
identical in composition and use. Even then it is a good idea to
independently charge each one periodically to try to maintain
identical charge states.
