Sorry,

I was trying to wind up the long concept and used
the term "overcharged" inappropriately. Given the
posed scenario, I attempted to explain, when the
charger detects the "need" for a considerable amount
of electrical charge (a dead battery or cell, for
example) the charger applies maximum amperage to the
entire bank (or banks, if the "boost" or "battery
switch" is "on") and that is akin to a pot of water on
the stove with the burner turned up to max heat - i.e.
the battery water/acid begins to literally "boil" and
the H2O component of the liquid evaporates, the
battery becomes hot to the touch, and as the liquid
level drops below the top of the closely aligned lead
plates, they begin to warp and touch one another, and
so on until permanent damage occurs. A vicious cycle!

An undamaged battery, properly charged, can
withstand ambient temperatures well down to zero
Fahrenheit for a considerable period of time. A
severely damaged battery (or cell) within a bank can
electrically drain the others, and at temps below
freezing, can result in multiple cracked cases.
