VRLA (Valve Regulated Lead Acid)/Gel Type batteries can be reasonably brought to life from zero volts to full voltage capacity at 13.1v for a 12v rated battery by charging the battery continuously for approximately 1 1/2 weeks. Rocket (Made in China) is the brand of VRLA/Gel battery I have used. My own test was undertaken on 4 VRLA/Gel battery I own. The charging voltage tested is 6 amps at 15v using automatic charger manufactured by Panther Philippines.
Unfortunately, the same procedure undertaken on a Motolite (Made in the Philippines) Solar Battery, a flooded deep cycle battery, does not work. At most, the Motolite battery only registers between 9v to 10v, after 2 weeks (Tested on 2 Motolite Batteries).

Notes on Lead Acid Battery
1. Positive and Negative: Lead Plates
2. Separator: Polyolefin
3. Electrolyte: Sulfuric Acid
4. Charging time (Single Cell): 24 hrs at 5v (Creates Lead Dioxide in the Positive Plate
5. Voltage Reading: 1.8 (Based on this; it will need 7 cells to create 12.6v or 8 cells which is preferred to create 14.4v for home solar use)
Note:
- The battery cell still got very high internal resistance, most probably on the use of solid Polyolefin separator; a separate test will be undertaken to determine the cause of very high internal resistance
