How Long Do Lead Batteries Last and How To Increase Their Lifespan?


Lead acid batteries have been around for the longest time, taking pride in being the first rechargeable batteries to ever exist. Lead-acid batteries have a well-established, mature technical foundation as they are used extensively as a backup power supply in many appliances, such as computer systems, battery-operated vehicles, and start-up engines. Even with the advancement of technology, these powerhouses have managed to stick around and are the most commonly used batteries in solar electric systems.

The cells' ability to supply considerable power surges suggests that they have a high power-to-weight ratio compared to a low energy-to-weight and energy-to-volume ratio. Although different designs could offer higher energy densities, lead–acid batteries are widely used even when surge current isn't an issue. These batteries are robust and boast a good power supply, but how long do they actually last? Read further to find out how long do lead acid batteries last?


Lead Acid Battery Life Span

Depending on the manufacturing procedure of the battery, sealed lead-acid batteries can have a life span ranging anywhere from 3-5 years, meaning they can last up to 1500 cycles.

On the other hand, nearly 50 percent of all flooded lead acid batteries do not last even half as long as they should. A battery might die in less than 18 months due to poor management, lack of monitoring, as well as low-effort proactive and reactive maintenance.

However, the cost of lead-acid batteries continues to climb on the market, and it is only fitting that you make the most out of such a hefty investment. Therefore, we have some surefire ways you can ensure to increase their lifespan.


How to Increase Lead Acid Battery Life Span?

Below mentioned are seven suggestions for extending the life of your lead acid batteries as much as possible, so you can make proper use of them.

Check the Water Levels Regularly 

Water will evaporate from your lead acid battery even in normal working conditions, which means you must keep a vigilant eye on the water levels. Do this every five to ten charges, and then replace with fresh, clean water as needed. To avoid impurities from clogging the battery, only use purified/distilled water.

It's important to remember that water should only be introduced after the battery has been fully charged.


Don't Let Your Battery Run Out Completely.

Sulphation can occur if a battery is discharged below 20% for an extended period. If sulphation begins to build up, it will obstruct electron flow, causing a delay in charging time, severely lowering the battery's productivity and lifespan.

To keep a battery from fully draining, adhere to a maintenance program and closely monitor battery charge levels, never allowing it to fall below 20%.


Do Not Overcharge the Battery

When a lead-acid battery is charged at an excessive voltage, the battery's water levels drop, and the temperature rises. This may result in some serious damage to your battery, eventually reducing its productivity and life span.  

Furthermore, the frequency with which a battery is charged might affect its longevity, as each battery has a maximum number of charge cycles it can withstand before losing its efficiency. With that in mind, charging a battery at every downtime opportunity isn't necessary, as each charge brings you closer to the maximum number of charge cycles, accelerating the need to replace that battery.

To avoid overcharging or charging a battery too frequently, it is critical to understand the correct charging parameters for each type of battery. You can ensure that each battery receives the proper amount of charge by using a battery management device, which can be easily purchased from a hardware store.

Do Not Overload the Battery with Appliances 

The pound load rate of each battery is different. When a lead-acid battery is subjected to a load greater than its specified weight, the battery is forced to produce more current than it was actually designed for. The increase in current can cause the battery to overheat, impairing it to a great extent.

To avoid overloading your equipment, every operator should know the maximum load weight for each battery that powers it. This will prevent the battery from losing its longevity. 


Keep a Check on the Temperature 

The temperature of the storage location significantly impacts battery performance and durability. Lead acid batteries should be stored in a cool, dry environment with a temperature of around 59°F (15°C) to work at their optimum state. Avoid storing your batteries in bright sunlight or near refrigerators to ensure that they are kept in the best possible condition.


Keep Your Batteries Clean

To avoid any damage to both the battery and the environment, it's critical to clean a battery as soon as possible after any overspills. If a spill is left unattended, the damage will only worsen over time, drastically diminishing the battery's life. A maintenance plan should be in place to ensure that each battery is thoroughly inspected for any spilled residuals on a regular basis.


Equalize Your Lead-Acid Batteries

The chemicals inside a battery get increasingly unbalanced as time goes on. Sulfate coatings on lead-acid batteries can build up over time, lowering the battery's total capacity and, in some situations, rendering it unusable. Equalization is a typical procedure used to avoid and remove sulfate buildup. It is a technique where you let your battery overcharge to give it that "push."

Experts recommend equalizing your batteries once a month to once or twice a year, depending on how frequently your battery is used to maintain a healthy battery and avoid sulfate residues.


The Bottom Line

So, now you know all about lead acid battery lifespan and how to increase lead acid battery life.

Lead-acid battery technology has been around for almost a century and is still in use today to power various appliances. When choosing a battery, make sure it's the right kind for the job at hand. Use the methods listed above to properly care for your lead acid batteries, and they will always be ready when you need them. With Brava Batteries, there is not much to worry about because we have got you covered with the most suitable batteries including high-quality lead-acid batteries for all your needs with constant professional support.
