Can a lead acid battery be fully charged?

This results in the battery being partially recharged quickly, but it requires prolonged charging to obtain a fully charged state. Neither constant current or step charging are ideal for stationary lead-acid batteries, and constant voltage charging is recommended. With constant voltage charging there are two common charging voltage levels:

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.
