- completely discharge your battery overnight by wiring a headlamp bulb across it, and then re-charge it fully. Do it a few times over a month.

Ummm... Rob? Are you sure about this one?

I have always taken it as gospel truth that deep-cycling a lead-acid battery was one of the many Really Bad Things (tm) you could do to it.

Can you explain to me what this will do and why it won't cause sulfation of the battery plates?
