Contact UsGel Battery vs. Lead Acid: The Differences Explained
Invented in 1860, rechargeable flooded lead-acid batteries are the most common and widely used type of lead-acid battery. Flooded batteries are composed of alternating lead and lead oxide plates along with liquid electrolytes (sulfuric acid and water). Using an electrochemical process, these components react to produce energy.

Try to charge the battery with the 12 volt charger. Hook it up to the battery charger and let it charge for a full cycle. Note: If you are using a smart or automatic charger and your Step # 1 voltage reading is below about 6.5 volts, then you will need to hook up the battery in parallel with another battery in order to charge it.
Contact UsCharging lead acid batteries in parallel? [closed]
All (not some) lead acid batteries I know need a "bulk" charge voltage over 14 Volts (look up the datasheet of any lead acid battery to confirm this). 13.8 V is just to maintain the charge ("float voltage"). You will never completely charge a lead acid battery by just applying 13.8 V. $endgroup$ –

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.
