<VV> battery area question

[Western Canada CORSA]

Have I got this ass-backwards, or not.

The vented battery was because the gases could react with the magnesium fan.
Or was it that they tried a plastic fan and the battery gases reacted with
the plastic; which is why they settled on magnesium?

Regards,
Joel

Joe,

The vented battery caps were STANDARD on ALL '65-9 Corvairs, and meant
to vent battery vapors out of the air stream of the heater. The Corvair,
by virtue of its design, was the only car to use them, and has been
forgotten by every battery maker since. So really, when we don't have
the batteries vented per factory design, we are risking whatever made
the engineers design the venting system in the first place. Oddly
enough, early Corvairs don't use a venting system, so my guess is that
the system was just overkill. Particularly since few of us anymore make
much use of the heater anyway.
