(ET) Charging batteries

[Neil Dennis <wombat RealNS com>]

Interesting, Grant:  In working as applications engineer for over 30
years on automotive charging systems, we always used a max of 14.4 volts
(2.4 v/cell) for voltage regulator settings on a 12 volt system with
usually 13.8 volts for "high temp" operating conditions.  I'll have to
do some looking, must be deep cycles are different.  At that charge rate
they must use a lot of water also.  Learn something new every day.
