Recharge rates for lithium batteries depends on the total Amp Hour (AH) rating of your battery bank and the output rating of your charger.  

For example, a 100 AH LiFePO4 Battery connected to a 60-Amp shore charger would recharge in under 2 hours.
 

A Lead/Acid Battery of the same size would take 15-20% longer to reach full charge.
