Lead-acid battery load drops seriously
The less sulpheric acid, the smaller the specific gravity, the nearer it gets to just water (SG = 1). So, if after charging part of that lead-sulphate did not reverse back into acid and lead/lead-oxide it means the SG will not bounce back to that of the straight acid as it was put into the battery, and your SG reading will show this.

About the Lead Acid Battery | Battery Council International
Lead batteries operate in a constant process of charge and discharge When a battery is connected to a load that needs electricity, such as a starter in a car, current flows from the battery and the battery then begins to discharge. As a battery begins to discharge, the lead plates become more alike, the acid becomes weaker and the voltage drops.

Voltage drop under load
It is perfectly normal/acceptable for the battery voltage to sag by 0.5 to 0.7 V under heavy load. As you observed, a good battery will recover in voltage when allowed to rest. The fact a battery voltage recovers is why applying Peukert''s correction is not very useful (you didn''t ask this question, but I wanted to use this opportunity to say it).
11.5: Batteries
Because galvanic cells can be self-contained and portable, they can be used as batteries and fuel cells. A battery (storage cell) is a galvanic cell (or a series of galvanic cells) that contains all the reactants needed to produce electricity. In contrast, a fuel cell is a galvanic cell that requires a constant external supply of one or more reactants to generate electricity.
