How Long Does Lead Acid Battery Last

How Long Does Lead Acid Battery Last?

A lead acid battery is a common type of energy storage battery used in homes and businesses. Lead acid batteries are usually made up of lead and acid, with lead being the main component. The lead acid battery is used to store energy and power various appliances.

Lead acid batteries can last anywhere from 5 to 8 years, but they will slowly lose their ability to hold a charge over time. Also, lead acid batteries need to be replaced every 8 to 10 years. This will vary depending on the type of lead acid battery, the environment it’s stored in, and the usage.

How long does it take for a lead acid battery to expire? Although lead-acid batteries are meant to last 5-8 years, but after 3-4 years of exploit. The truth is that they are already reaching the end of their lifespan, and many people believe that they have not deteriorated as much in recent years, and that they are even less durable in winter. Other significant variables influencing the quality of the product, rather than just objective facts of existence, are not as good as before.

Are lead-acid batteries really becoming less reliable? How long does a typical battery have to live? To do so, we must first understand a premise and discover how to define the battery’s life.

1. The number of charging and discharging cycles a battery can endure is its life.

While “life” is a notion of time, the quantity of cycles undergone by lead-acid batteries to more precisely define it is a idea of time specifically associated with lead-acid batteries. For example, if a battery product has a rating of 400 to 600 cycles, it indicates that the battery’s life cycle may be completed in the range of charge and discharge cycles indicated.

There are two points to note here.

First, because of the complexity of the actual use of the battery environment, the actual number of cycles of charging and discharging may not reach the nominal value.

Second, the number of cycles refers to the number of complete cycles, not the number of charges. It is the process of the battery going from zero charge to full charge (or vice versa) that is a cycle. For example, assuming the vehicle is fully charged with 50% charge remaining, it would only be considered 0.5 cycles.

The battery’s life is supposed to be longer as the number of charge/discharge cycles increases. Even if we restrict the number of times per week that a battery is used, it is impossible to say when a battery will reach its maximum capacity.

2. How long does a new battery last?

Generally speaking, a 12V lead-acid battery is designed to have a float life of 5-8 years, but in actual use, it is common to see complete obsolescence in 1-2 years. Just like the cycle life mentioned above, any lead-acid battery (including deep cycle and sealed lead acid battery) always escapes the cycle of early retirement in use. This is more than 140 years since the invention of lead-acid batteries, the world’s most recognized worldwide problem—lead-acid batteries “irreversible sulfide”, is that it leads to a substantial reduction in battery life, and make the battery early retirement.

Can we slow the aging of batteries now that we know who is responsible for causing lead-acid batteries to shrink in life? Obviously, if you avoid the following situations frequently, a group of high-quality batteries may typically last for around 3 years, such as charging with low quality or overcharging or undercharging on the street fast charging or emergency brake to stop.

It can be seen that the service life of the battery is not only the concern of the battery itself, but also related to its use conditions, environment, user habits, etc.

As a result, in addition to purchasing appropriate battery products, we should learn to pay attention to the upkeep of the battery, as opposed to lithium-ion batteries, since lead-acid batteries are regularly charged and discharged under unprotected circumstances.

How to prolong lead acid battery life

Lead acid batteries are a common fixture in homes and businesses, and for a good reason—they’re reliable and long-lasting. However, like all batteries, lead acid batteries will eventually wear out. Here are some tips to help you prolong battery life:

— Always charge your lead acid battery fully before use. This will ensure that the battery is at its most powerful.

— Discharge the battery gradually by running it down to 50% capacity and then recharging it back up to full power. This will help to prevent damage and increase the battery’s lifespan.

— Keep the battery clean – alcohol can be used to remove tar, oil, and corrosion from the plates.

— If you notice any signs of wear or tear, replace your battery immediately.

Frequently Asked Questions

What are the common lead acid battery types?

There are three main types of lead acid batteries: valve-regulated lead acid, flooded cell, and sealed gel.

Each type of battery has its own pros and cons that you must take into account when deciding which one to use for your needs.

Valve-regulated lead acid batteries have the advantages of low maintenance costs and longer runtime than other batteries. Flooded cell batteries tend to be cheaper and last longer than sealed gel batteries, but they require periodic charging.

How long does a typical lead acid battery last?

A lead acid battery typically lasts for between three and six years. To extend the life of your battery, charge it at a lower voltage, keep it cool, and store it properly.

What should I do if my lead acid battery starts to emit an odor or smoke?

If you’re experiencing any of the following symptoms, it means that your lead acid battery is close to going bad and needs to be serviced as soon as possible.

– You notice an increase in smells or vibration levels.

– The battery starts emitting an unpleasant odor or smoke.

– The battery’s life is nearing the end.

How can I tell if my lead acid battery needs to be replaced?

Most lead acid batteries have a lifespan of around 10 years, but this could vary depending on the type and condition of the battery. To check the batteries’ lifespan, first make sure you’re charging them at the correct voltage (which is typically 12 volts). If the battery does not hold a charge or starts to discharge slowly, it may be time for a new lead acid battery to be installed.

It is important to regularly check your lead acid battery’s voltage (how much electricity it can hold), oil level, water level and color. Checking these levels will help you determine when the battery needs to be serviced or replaced.

Is it safe to charge a Lead Acid Battery in your car?

Lead acid batteries are not recommended for charging in a car, as batteries of this type are not designed to be charged deep down. This means that you should only charge them using a trickle charging method. Additionally, never let a lead acid battery discharge completely. Doing so can damage it and lead to a fire.


Lead acid batteries are a significant part of many devices and are used to power a wide range of appliances. By understanding how long lead acid batteries last and the cost of replacement, you can make smart choices about how to use and maintain your battery. Plus, by following a few simple tips, you can prolong the life of your lead acid battery. So what are you waiting for? Check out our blog for more information on lead acid batteries!
