Frequently Asked Questions

SULFATION (Lead Sulfate crystallization) produces electrical insulation on plates, reduces pore size on negative plates, reduces surface area for ionic diffusion to generate power. Reduced ionic diffusion generates more heat and increased electrolysis resulting in more gas formation and loss of electrolyte. 

When batteries pickup irreversible Sulfation following changes are noticed in batteries. 

1. More heat generation less power back up. 
2. More water loss. 
3. Requires frequent water topping. 
4. More gas formation from batteries. 
5. Less power back up and quick discharge. 
6. Discharged batteries need more charging hours but less power storage EFFICIENCY. 
7. Due to more heat and gas generation rate of corrosion increases.
8. Operating costs increased due to less back up power and more power needed to recharge. 
9. Sulfated batteries consume more power to recharge and time. 
10. Increased temperature and gas generation damages battery separators.
11. Sulfation is main cause for premature death of batteries. It is important to have batteries that are free from Sulfation. Even new batteries are not free from Sulfation.

All batteries, including those that are merely stored and not in use, undergo a certain degree of self-discharge. 

However, the rate at which lead-acid batteries self-discharge is influenced by several important factors.

1. Additives in the negative paste play key role in self discharge.
2. Different alloys of negative plates and alloy of terminal post add to increased self discharge.
3. Separators pore size reduces due to sulfation, adding to self discharge.
4. Distance between positive and negative plates if too close will add up to self discharge.

To address this, choose negative paste additives carefully. Ensure that additives have synergies in the end results.

1. Undercharging a battery is not as harmful as leaving undercharged battery in unused conditions. Sulfation builds rapidly in under charged battery when left for long time. 
2. Overcharging doesn't help to remove Sulfation. On the contrary presence of sulfation promotes overcharging. 
3. Overcharging an AGM batteries results in bulging of battery cases due to gas accumulation. Oxygen recombination efficacy of most AGM batteries is far below the required International standards and most ignored parameter of AGM batteries.
