RE: (ET) batteries - (re)building website

["Markus Lorch" <mlorch vt edu>]

Thanks John,

very interesting. The guy publishing this website claims that sulfation
is very rarely the reason for battery failure. Here a section from his 
website:

"Lead acid batteries can die from a number of causes but no matter what the
cause they can be rebuilt.
According to all the battery manufactures and other sources of information 
I
have read - the leading cause of battery death is due to sulfation 
(Although
I have never seen one). The second cause is shorted cells (I have seen 
heaps
of these). 
The third is cell interconection failure due to corrosion (I have also seen
a few of these).
Other causes are excessive top up with contaminated water, broken casings
and general old age. 
In my experience every failure I have seen can be attributed to anodic
corrosion. The positive plates have simply corroded away.
"

Interestingly, to form the plates when he builds/rebuild a battery he
purposely 
revereses the battery polarity several times to build lead peroxide, which
in turn
increases the surface area and thus increases capacity (according to him)

Hi All,
A couple people (Bill & Markus) asked for the website, so here it is:

Also, book (download PDF from same website) was from 1922.
