Now that the subject has come up. I have some 6V sealed lead acid batteries from
 the kids Power
Wheels cars that are getting weak. I have seen some advertizing and searched pat
ents on pulsing
lead acid batteries to eliminate plate sulfation. I don't think that this charge
s the batteries
rather just cleans the plates. I am interested in finding the pulse voltage, fre
quency and
duration needed to rejuventate lead acid batteries. I figure a PIC could control
 it nicely. I only
plan to use it to save the power wheels batteries and maybe my cars not developi
ng a product.

As a side note. One of the 'brilliant' engineers here used a 12V supply with cro
wbar to charge his
old car battery. Wasn't he suprised when the battery hit 12V. Needless to say he
 is a manager now.
His hair seems quite pointy too.
