The Curing of Lead-Acid Battery Plates 57 With the oven set to 175°C, plates were dried for either 2 min or 10 min. Originally the paste contained 12-7 per cent water and 16-1 per cent free lead.
ABSTRACT Ways are considered of accelerating the curing process through closer control of conditions. To ensure uniformly-fast processing, plates should be hung vertically in racks rather than stacked horizontally. The atmosphere should be maintained at 30°C and at 100 per cent relative humidity.
Several changes occur during curing. Oxidation of the residual metallic lead in the paste takes place, with evolution of heat, and the plates dry out. Corrosion processes occurring at the surface of the grid help the paste to adhere and the microstructure of the active material changes.
Curing temperature not to exceed 160°F. The purpose of the flash dryer is to dry only the surface of the plates. The Curing of Lead-Acid Battery Plates 67 M. E. D. HUMPHREYS: NO, I am sorry we have not.
When the temperature is increased and an appropriate humidity cyclogram is chosen, the curing processes are enhanced which allows the duration of the curing process to be reduced from 72 to 48h. However, temperature rise is limited to 65°C because above this temperature, a transformation reaction of to begins.
Batteries 1-6 contained plates cured for 12 hr under conditions suggested by this investigation, while batteries 7 and 8 contained plates cured for 72 hr in 15-in. high stacks. DISCUSSION Two substances are essential for the oxidation of the small particles of metallic lead present in the paste: oxygen and water.

Curing of the positive paste is the most time consuming technological procedure in the process of lead‐acid battery manufacture. During curing the following processes take place: Pb oxidation, and oxide recrystallization, grid corrosion, improvement of the paste/grid contact, and drying of the plate.
Get a fresh battery. If you really must fix a hole in your battery, get a good quality acid resistant glue or do a plastic weld. Remember to also clean or replace any corroded battery terminals and wash all traces of acid from the battery compartment with a neutralizing solution like soda bicarbonate or soapy water.
