Lead acid batteries are rechargeable energy storage devices commonly used in vehicles, uninterruptible power supplies, and various other applications. They consist of lead plates submerged in an electrolyte solution of sulfuric acid and water. These batteries produce electricity through a chemical reaction between the lead plates and the electrolyte.
Proper maintenance of lead acid batteries is crucial for ensuring their longevity and optimal performance. Regular care can prevent premature failure, extend battery life, and maintain efficiency. Neglecting maintenance can lead to reduced capacity, shortened lifespan, and potentially dangerous situations.
Battery revival, also known as reconditioning, is the process of restoring a weakened or seemingly dead lead acid battery to a functional state. This process typically involves cleaning, desulfation, and recharging techniques aimed at reversing the effects of sulfation and other forms of deterioration.
Sulfation: The buildup of lead sulfate crystals on battery plates, reducing the battery's ability to hold a charge.
Overcharging or undercharging: Improper charging practices can damage the battery's internal components.
Electrolyte loss: Evaporation or leakage of the electrolyte solution can impair battery function.
Physical damage: Cracks, corrosion, or other physical harm can compromise the battery's integrity.
Age: Batteries naturally degrade over time, even with proper maintenance.
Slow engine crank or difficulty starting the vehicle
Dimming headlights or other electrical issues
Swollen battery case
Unusual odor (rotten egg smell)
Low electrolyte levels
Corroded terminals
Battery not holding a charge
Revival is often possible when:
The battery is relatively new (less than 3-4 years old)
Sulfation is the primary issue
There's no physical damage to the battery case
The battery still holds some charge
Replacement is necessary when:
The battery is old (more than 4-5 years)
There's significant physical damage or internal shorting
Multiple cells are dead
The battery fails to hold any charge after reconditioning attempts
Safety goggles or face shield to protect eyes from acid splashes
Acid-resistant gloves (rubber or neoprene) to protect hands
Protective clothing such as a long-sleeved shirt and pants
Closed-toe shoes or boots
Apron or lab coat for additional protection
Work in a well-ventilated area, preferably outdoors or in a garage with open doors
Use fans to circulate air if working indoors
Avoid working in enclosed spaces without proper ventilation
Be aware of potential hydrogen gas buildup during charging
Always add acid to water, never water to acid
Use a plastic funnel when pouring acid to prevent spills
Keep a neutralizing agent (baking soda or commercial neutralizer) nearby
Know the location of emergency eyewash stations or have a clean water source available

Remove corrosion using a baking soda solution
Dry the battery thoroughly after cleaning
Remove cell caps carefully
Check electrolyte levels in each cell
If low, add distilled water to just cover the plates
Do not overfill as the electrolyte expands during charging
Use a low-amperage charger to apply a pulsing current
Alternatively, use a dedicated desulfator device
Continue the process for 24-48 hours, depending on battery condition
Monitor battery temperature to prevent overheating
Use a multi-stage charger for optimal results
Start with a low-amperage charge (2-10 amps)
Allow for a full charge cycle, which may take 12-24 hours
Avoid overcharging by using a charger with automatic shut-off
Use a voltmeter to check resting voltage (should be 12.6V or higher for a fully charged battery)
Perform a load test to assess the battery's ability to hold charge under stress
Check specific gravity with a hydrometer (should be between 1.265 and 1.299 for a fully charged cell)
Monitor the battery's performance over several charge/discharge cycles
Remove battery caps and drain the old electrolyte
Mix Epsom salt (magnesium sulfate) with distilled water to create a new electrolyte solution
Fill each cell with the Epsom salt solution
Charge the battery and test performance
Note: This method may provide temporary improvement but can shorten overall battery life
Remove battery caps
Crush 12-15 aspirin tablets and dissolve in warm distilled water
Add the aspirin solution to each cell
Charge the battery and test performance
Caution: This method's effectiveness is debated and may not work for all batteries
