Battery types used in cars and other vehicles include lead-acid batteries. They are also used in many other applications such as UPS systems, solar power systems, and more. 

Lead acid batteries have a number of advantages over other types of batteries, including their low cost and high energy density. However, lead acid batteries also have a number of disadvantages, one of which is their relatively short lifespan. 

There are a number of ways to increase the life span of a lead acid battery, including proper charging, maintenance, and storage. In this article, we will discuss how to increase lead acid battery life.

How Many Times Can a Lead Acid Battery Be Recharged?

How Many Times Can a Lead Acid Battery Be Recharged

A lead acid battery is a type of rechargeable battery that has been around for over 150 years. Despite their age, lead acid batteries are still used in a variety of applications, including cars, trucks, and boats. 

Lead acid batteries are made up of two lead plates immersed in a sulfuric acid solution. During discharge, the sulfuric acid reacts with the lead plates to form lead sulfate. Battery recharge converts lead sulfate back into acid and leads after it has been discharged.

This process can be repeated many times, but eventually, the lead plates will start to degrade. The number of times a lead acid battery can be recharged before it needs to be replaced depends on a number of factors, including the type of battery, the depth of discharge, and the charging method.

Lead Acid Battery Life Calculator

A lead acid battery life calculator can be a useful tool to help estimate how long your lead acid battery will last. There are a few factors to consider when using a lead acid battery life calculator, including the type of lead acid battery you have, the temperature, and the discharge rate.

The type of lead acid battery is important to consider because there are two main types of lead acid batteries: Flooded and sealed. The flooded type is typically used in cars and trucks, while the sealed type is often used in marine applications. 

The temperature is also an important factor to consider because higher temperatures will shorten the life of your lead acid battery. Finally, the discharge rate is also an important factor because faster discharge rates will also shorten the life of your lead acid battery.

How to Bring a Dead Lead Acid Battery Back to Life?

How to Bring a Dead Lead Acid Battery Back to Life

Ensure that the lead acid battery is truly dead by checking for a voltage reading of 12.6 volts or less with a voltmeter. If the voltage reading is above 12.6 volts, the battery may only be low on charge and can be revived with a simple charging procedure. 

To revive a lead acid battery, first, clean the terminals and check the electrolyte level. If necessary, add distilled water to bring the electrolyte level up to the fill line. Once the terminals are clean and the electrolyte level is correct, charge the battery using a slow charger overnight. 

Do not overcharge the battery, as this can damage it beyond repair. Once charged, test the battery using a load tester to ensure that it is holding a charge. If necessary, repeat the charging process until the lead acid battery is revived and functioning properly.


In conclusion, by following the steps above on how to increase lead acid battery life, batteries will be able to provide power for a longer period of time. Increasing the lifespan of batteries helps to save money and resources. Additionally, it is important to properly dispose of batteries at the end of their lifespan to prevent environmental contamination.


Q1. Why is My Lead Acid Battery Draining So Fast?

An undercharge. Battery damage can occur either if a battery is overcharged or undercharged. Leaving the charger on until the battery is fully charged will cause it to drain more quickly.

Q2. What Damages Lead Acid Battery Cause?

Leaving a lead acid battery “dead” for an extended period of time can result in the battery’s life being compromised. Lead acid batteries should not be discharged below 30% or they could be damaged.

Q3. How Long Will a Lead Acid Battery Last If Not Used?

An SLA battery should never be left unused for more than six months without being recharged. Keep batteries dry and cool. When kept at mild temperatures, a battery can generally last six months to a year.
