If a SLA battery is allowed to discharge to a certain point, you may end up with sulfation and render your battery useless, never getting the intended life span out of the battery. Sulfation is when the electrolyte in the sealed lead acid battery begins to break down. Sulfur in the solution leachs from the electrolyte and. . The combination of these issues weakens the ability of the battery to accept and and deliver a charge. If you are going to store sealed lead acid batteries on a shelf without charging them, it is. . When storing sealed lead acid batteries for long periods, it is recommended that you top charge the batteries periodically. The top charge should be for 20 – 24 hours at a constant voltage of 2.4. . If your SLA battery has been stored for some time and is now not holding a charge then it is no longer serviceable and will need to be replaced. Whatever the battery is, BatteryGuy can. A lead-acid battery typically lasts between 3 to 5 years under standard conditions. The lifespan can vary based on several factors, including battery type, usage, and maintenance. [pdf]
The lifespan of a lead-acid battery typically ranges from 3-8 years: Flooded Lead-Acid Batteries: Usually last around 4 to 6 years. Sealed Lead-Acid Batteries (AGM, Gel): Generally last about 3 to 5 years. Factors Affecting Lifespan Usage Conditions: Frequent deep discharges and high discharge rates can shorten the lifespan.
Sealed Lead Acid batteries should be charged at least every 6 – 9 months. A sealed lead acid battery generally discharges 3% every month. If a SLA battery is allowed to discharge to a certain point, you may end up with sulfation and render your battery useless, never getting the intended life span out of the battery.
Temperature plays a vital role in battery performance. Extreme heat can shorten lifespan, while extreme cold can affect capacity. Storing batteries in a moderated environment ensures better longevity. By adopting these maintenance tips, users can maximize their lead acid battery lifespan.
Higher temperatures significantly prolong battery life. You can leave a lead acid battery uncharged indefinitely. Double the charging voltage will double the battery lifespan. Using a battery regularly is more harmful than letting it sit unused. Lead acid batteries should be fully discharged before recharging is a common myth.
The number of charge cycles a lead-acid battery can undergo depends on the type of battery and the quality of the battery. Generally, a well-maintained lead-acid battery can undergo around 500 to 1500 charge cycles. What maintenance practices extend the life of a lead acid battery?
Proper charging is essential for extending the life of lead-acid batteries. Overcharging or undercharging can harm the battery, reducing its lifespan. Always use a charger suited for your battery type and size. Charge it at the correct voltage and amperage as per the manufacturer’s guidelines.

Luckily, sulfation can be reversed and prevented. The lead sulfate that has hardened and crystallized, which can’t be removed by charging, can be removed by another process, called desulfation. This is the most important aspect of battery reconditioning. Applying a very high voltage to the battery plates. . As we mentioned earlier, discharging a battery means sulfation will develop. Fact. There’s nothing you can do about it. The more discharge, the more lead sulfate develops on the battery plates. A desulfator charger is great. . Sulfation is not the only issue that can afflict batteries. There is also acid stratification, which can also be called acid layering. A well-rounded. . Around 50% of all breakdowns are due to battery failure. And as we said earlier, 84% of all battery failures are due to sulfation. That means the. According to battery experts, it can take an average of 48 hours to two weeks to desulfate a lead-acid battery. [pdf]
Lead acid batteries can sometimes sustain damage that cannot be repaired through reconditioning. A common issue is sulfation, where lead sulfate crystals accumulate on the battery plates. Severe sulfation may reduce the battery’s capacity beyond recovery, making replacement necessary.
The primary reason for the relatively short cycle life of a lead acid battery is depletion of the active material. According to the 2010 BCI Failure Modes Study, plate/grid-related breakdown has increased from 30 percent 5 years ago to 39 percent today.
The actual process is dependent on the type of battery we are talking about. In a lead acid battery, The cell voltage will rise somewhat every time the discharge is stopped. This is due to the diffusion of the acid from the main body of electrolyte into the plates, resulting in an increased concentration in the plates.
If at all possible, operate at moderate temperature and avoid deep discharges; charge as often as you can (See BU-403: Charging Lead Acid) The primary reason for the relatively short cycle life of a lead acid battery is depletion of the active material.
Steps to Recondition a Lead-Acid Battery Safety First: Wear safety goggles and gloves to protect yourself from the corrosive acid. Remove the Battery: Take the battery out of the vehicle or equipment. Open the Cells: Remove the caps from the battery cells. Some batteries have screw-in caps, while others have rubber plugs.
Once the phosphoric acid is added and the cells topped up you want to charge the battery for about 3 full days, a week if only charge during the day or night due to monitoring the process. During the charge the lead oxide (PbO2) is reduced back to lead. The presence of our phosphoric acid now also reduces the phosphate on the lead plates.

Ironically one of the most common reasons for battery failure is not an actual failure of the battery itself, it is people thinking the battery is dead. Some manufacturers and retailers report that up to 50% of batteries returned under warranty are actually fit and healthy. Another interesting fact is that most people have met. . The positive and negative electrodes (plates) in any battery cannot touch each other. If they do, they immediately short out and the cell dies. Note, this does not mean the entire battery. . If lead acid batteries are cycled too deeply their plates can deform. Starter batteries are not meant to fall below 70% state of charge and deep cycle units can be at risk if they are regularly. . When a lead acid battery discharges, the sulfates in the electrolyte attach themselves to the plates. During recharge, the sulfates move back. . Acid stratification occurs in flooded lead acid batteries which are never fully recharged. This is especially common in vehicles which are used for short journeys since there is not enough. [pdf]

All rechargeable batteries degrade over time. Lead acid and sealed lead acid batteries are no exception. The question is, what exactly happens that causes lead acid batteries to die? This article assumes you have an understanding of the internal structure and make up of lead acid batteries.
Lead acid batteries need a specific 3-stage charge process 6 in order to preserve their condition. In practice, if you don't discharge a battery beyond 50%, it takes less time to recharge the battery 7. It can be a good idea to hookup unused batteries permanently to a 'tricklecharger'.
