Pulse charging is used to revive tired lead acid battery which is either improperly
charged/discharged or allowed to self-discharge as occurs during non-use. Basically,

A high constant current is provided so the battery can be quickly charged to 2.4V
per cell.
A constant voltage of 2.4V per cell is provided until the charging current naturally
tapers down to a low level.
