The advice is correct. Lead-acid batteries do not develop "memory". NiCad batteries do. Completely discharging a lead-acid battery is the quickest way to shorten its life. The lead oxidizes. Try to recover lead from long-dead batteries and you won't find any. Only lead oxide. (don't ask me how I know that). Regarding "deep-cycle" and "starting" (lead-acid) batteries: The difference is in the lead plates. Starting batteries have holes or fins in the lead plates to present more surface area to the acid and give more power quickly. "deep-cycle" batteries have solid plates and discharge more slowly but provide power over a longer period of time. Bob ----- Original Message ----- From: E.
