I came across this interesting article to convert a standard lead acid battery into alkaline: http://blog.hasslberger.com/2007/01/how_to_convert_a_lead_acid_bat.html Seems very promising. Not only does the capacity increase slightly, but the battery also withstands deep discharges much better than a conventional lead acid. Still charge with approximately the same voltage. Perfect right? There are a few testimonials of the success and failures of people attempting this conversion. I am just curious as to what you guys think. Would love to hear an intelligent opinion on this matter.
