Do lead acid batteries need to be fully discharged?
Since that is no longer an issue (and never was an issue with lead acid batteries) there is not a need to fully discharge. By discharging a lead acid battery to below the manufacturer's stated end of life discharge voltage you are allowing the polarity of some of the weaker cells to become reversed.
How long should a lead acid battery stay discharged?
Lead acid batteries should never stay discharged for a long time, ideally not longer than a day. It's best to immediately charge a lead acid battery after a (partial) discharge to keep them from quickly deteriorating.
What happens when a lead acid battery is charged?
Voltage of lead acid battery upon charging. The charging reaction converts the lead sulfate at the negative electrode to lead. At the positive terminal the reaction converts the lead to lead oxide. As a by-product of this reaction, hydrogen is evolved.
Should a lead acid battery be fused?
