Trickle charge it for a few days From wiki trickle charging is charging rate is equal to discharge rate*, trickle charging happens naturally at the end-of-charge, when the lead-acid battery internal resistance to the charging current increases enough to reduce additional charging current to a trickle, hence the name.
The ability of pulse charging to restore a lead-acid battery depends on various factors, including the extent of the depletion and the battery''s condition. Pulse charging involves sending short bursts of high current to the battery, which can help to reduce sulfation, a process that occurs when lead sulfate crystals form on the battery plates during discharge.
