Why Choose Lithium Inverter Storage Systems over Lead Acid

May 27, 2024June 12, 2024 By lithiuminverter

Why are lithium batteries better than lead-acid?

Lithium batteries outperform lead-acid batteries in several key areas, making them the preferred choice for many modern applications. Here’s a breakdown of the advantages:

Energy Density: Energy density refers to how much energy a battery can store in a given amount of space (volume) or weight. It’s a measure of how efficient the battery is at packing a punch.

Here’s how lithium and lead-acid batteries compare:

Lithium Ion Batteries:

High Energy Density: Lithium-ion batteries boast a much higher energy density, typically ranging from 250 to 670 Wh/L (Watt-hours per Liter). This means a lithium-ion battery can store a significant amount of energy in a relatively small and lightweight package.

Lead-Acid Batteries:

Lower Energy Density: Lead-acid batteries, in contrast, have a much lower energy density, typically in the range of 30 to 50 Wh/L. This translates to needing a larger and heavier battery to store the same amount of energy as a lithium-ion battery.

Portability: Since lithium-ion batteries store more energy in a smaller space, they’re perfect for powering portable electronics like laptops, phones, and cameras.

Electric Vehicles: The high energy density allows electric vehicles equipped with lithium-ion batteries to travel longer distances on a single charge compared to those using lead-acid batteries.

Weight: For the same amount of energy storage, lithium batteries weigh considerably less than lead-acid batteries. This makes them ideal for applications where weight is a major concern, like electric vehicles and portable electronics.

Charging Speed: Charging speed is a big advantage for lithium batteries over lead-acid batteries. Here’s a breakdown of why:

Lithium-ion Batteries:

Faster Charging: Lithium-ion batteries can generally accept a higher charge rate compared to lead-acid batteries. This means they can reach a full charge much quicker. Think hours for lithium-ion batteries compared to potentially 8 hours or more for lead-acid.
Lithium Chemistry: The internal chemistry of lithium-ion batteries allows for faster movement of ions during charging, leading to quicker energy intake.

Lead-Acid Batteries:

Slower Charging: Lead-acid batteries require a slower and more controlled charging process. Forcing a faster charge can damage the battery and shorten its lifespan.
Crystallization Risk: During rapid charging, lead sulfate crystals can form on the lead plates within the battery. This can hinder its ability to store energy effectively.

Here’s what faster charging with lithium-ion batteries means in practical terms:

Convenience: You can recharge your phone or laptop in a shorter amount of time, keeping you connected and productive.
Electric Vehicles: Electric vehicles with lithium-ion batteries can be refueled (charged) much faster than those with lead-acid batteries, reducing downtime at charging stations.

Some additional points to consider:

Specific charging times can vary depending on the size and capacity of the battery, as well as the charger’s capabilities.
While lithium-ion batteries can handle faster charging, some manufacturers recommend slower charging rates to maximize battery life.

Lifespan: Lithium batteries typically have a longer lifespan than lead-acid batteries. They can go through more charge cycles before needing replacement.
Depth of Discharge: Lithium batteries deliver a higher percentage of their stored energy compared to lead-acid batteries. You get more usable power out of a lithium battery before needing a recharge.
Constant Power Delivery: Lithium batteries maintain a more consistent voltage output throughout their discharge cycle. Lead-acid batteries tend to weaken as they discharge.

There are some downsides to consider though. Lithium batteries are generally more expensive upfront than lead-acid batteries. Also, they require special care and handling to ensure safety.

Overall, lithium batteries offer superior performance in most applications. Their higher upfront cost can be offset by their longer lifespan and improved efficiency.

Lithium Batteries are Now Cheaper than Tubular Batteries

Lithium Batteries are Now Cheaper than Tubular Batteries, Lead-acid and lithium batteries are two of the most common types of batteries today.

They have different advantages and disadvantages, so the best type of battery for you will depend on your specific needs.

The Benefits of Replacing Gensets with Lithium-based Battery ESS

Lead-acid batteries are typically less expensive than lithium batteries.

However, the cost of lithium batteries has been declining in recent years, and they are becoming more affordable.

The lead Acid battery comes with a C20 capacity, and Lithium Battery comes with a C1 or C3 capacity.

So there is no match between Lead Acid and Lithium battery as per capacity at discharge level.

As Tubular Lead Acid battery is the most acceptable battery in Inverter, UPS and solar System applications .

So it’s imperative to compare these two technologies and give the proper perspective to the consumer.

So to run the higher load, like 1000 Watt for 12-volt Inverter/UPS or solar PCU application, draws 83 Amp from the lead Acid battery.

Hence, the 200Ah Tubular battery becomes a 60 Ah battery, if the 83 aamp current is drawn.

So we just need 70 Ah lithium battery to get the more back up compare to 200 Ah Tubular battery.

So if we compare the cost of Lithium LifePo4 battery and Tubular lead Acid battery of these two sizes.

We realize the Lithium battery price of 70 Ah is lesser than Tubular battery price of 200 Ah

So we have to compare Lithium batteries Vs Tubular Lead Acid batteries.

https://suvastika.com/lithium-battery-is-cheaper-than-tubular-battery-in-ups-inverter-usage/#:~:text=So%2C%20if%20we%20compare%20the,battery%20price%20of%20200%20Ah.&text=One%20must%20understand%20the%20backup,Acid%20batteries%20are%20obsolete%20today.

Lithium Batteries are Now Cheaper than Tubular Batteries

One must understand the backup time calculations done on Peukert’s Law for Lead Acid batteries is obsolete today.

So far, the manufacturers and dealer distributors have not made any chart that Tubular Lead Acid battery performance at higher Loads discharge.

Weight and volume

Lead-acid batteries are no comparison as a 200 Ah Tubular battery is 60 kg and a 70 Ah lithium battery of 12.8 v is not even 6 kg in weight.

Energy density

Lithium batteries have a higher energy density than lead-acid batteries. Lithium batteries can store more energy in a given volume or weight.

Charging time

Lithium batteries can be charged in 2 hours, and Tubular batteries take a minimum of 15 hours to be completely charged.

So Lithium batteries can give five times back up in a day if there are intermittent power cuts.

Where as the tubular batteries will not be able to give two times back up in a day.

Cycle life

Lithium batteries have four times the life of tubular batteries. the Lithium battery comes with a Digital Warranty of 3 years.

Operating temperature range

Lithium batteries have a narrower operating temperature range than lead-acid batteries. This means that lithium batteries are less tolerant of extreme temperatures.

Safety

Lead-acid batteries are less safe than lithium batteries. This is because lead-acid batteries can release lead fumes when charged or discharged for any home or office, which should be avoided as Lead has been banned in most areas.

We have kept the provision in our few models for Tubular and Lithium LifePO4 batteries. The user can select which battery to install as per his knowledge and understanding.

Tubular batteries Vs Lithium Baterries

Lithium Batteries are Now Cheaper than Tubular Batteries

Maintenance Tubular lead acid battery needs distilled water topping once in 3 to 6 months, which is such a big headache for the user to get the distilled water and refill in time. After the refill, the acid comes out on the floor, which destroys the marble floor also.

Overall

Lithium batteries have several advantages over lead-acid batteries, including higher energy density, longer cycle life, and faster charging time. However, lithium batteries are also more expensive and have a narrower operating temperature range. The best type of battery for you will depend on your specific needs and budget.

Here are some additional considerations when choosing between lead-acid and lithium batteries:

Application: If you need a battery for a high-performance application, such as to run higher loads like fridges, geysers Airconditioners, Laser printers, CNC Machinery, microwave ovens, Coffee machines etc., but if you want to run small loads of house like fans LEd lights and TV etc. than the Lead Acid can be a choice but refilling the water and space taken is a big challenge.
Price Point: if one sees all these benefits and comparisons, one can realize that a Lithium battery LifePO4 is cheaper than a Tubular lead Acid battery.
Operating environment: A lithium battery is a better choice if you live in an area with extreme temperatures. Lead-acid batteries are not as tolerant of extreme temperatures. They need ATC features in the UPS.

Typically, local Lithium battery banks lack a Battery Management System (BMS). As a result, the lithium battery cells become unbalanced and can lead to battery bank failure, which can be disastrous.

We will be adding a Wi-Fi feature to our lithium battery bank, along with the optional GPS, for remote monitoring. This will ensure that battery swapping is a smooth process and customers are aware of its status. The seller can also track the battery’s place and status for better after-sale service issues. Lithium battery is an important area of technology where the focus is to develop the BMS (Battery Management System) that defines the life and the best output of the Lithium cells.

We have created new technologies in this field and are continuously filing patents in this area. More and more technology patents are emerging as we are sure to capture the E-Vehicle market in the next 2 to 5 years by using our Lithium battery technology.

The major challenge faced by the electric vehicle industry is lithium batteries and their charging techniques. We are working on manufacturing Lithium lifP04 batteries In-house, for which In-house BMS and In-house manufacturing capabilities are being created. Also working on high-capacity battery banks is the future for the high-capacity UPS and big Solar Projects.

We have already filed patents for the same. Lithium battery technology is bringing the revolution in the Heavy duty UPS (3Phase) as it will replace the Heavy Duty 3-Phase Generators because the cost of running it, is much cheaper and it can be easily maintained without getting the oil refueling and maintenance.

Faster charging: Lithium batteries recharge much faster than SLA batteries, minimizing downtime after a power cut. This is crucial for situations where you rely heavily on backup power.
Lower maintenance: Unlike SLA batteries, lithium batteries require minimal maintenance. You won’t need to worry about topping up water or checking acid levels.

Advantages and Disadvantages Li Battery vs Tubular Battery

The Lifespan of Lithium vs. Lead Acid: A Comparative Study

Tubular Lead Acid Battery: Tubular lead acid batteries, while a popular choice for inverter systems, come with some drawbacks compared to newer lithium battery technology, These batteries typically have a lifespan of 2-3 years. Their capacity degrades with each charge/discharge cycle, and deep discharges significantly shorten their life.

Lifespan: 2-3 years or 300-500 cycles (depending on factors like depth of discharge)
Disadvantages:
- Shorter lifespan compared to lithium batteries, requiring more frequent replacements and higher overall costs.
- Higher capacity degradation with each cycle leads to a faster decline in performance.
- Limited depth of discharge (around 50%) to maintain lifespan, reducing usable backup power.

Limited Depth of Discharge: Deep discharging (below 50%) can significantly shorten a tubular battery’s lifespan. This limits the usable capacity of the battery during an outage.
Slower charging: Tubular batteries take longer to recharge than lithium batteries, increasing downtime after a power cut.

Maintenance requirements: Unlike lithium batteries, tubular batteries require regular maintenance, such as topping up with distilled water and cleaning the terminals. Neglecting this maintenance can lead to reduced performance and a shorter lifespan.

Weight and size: Tubular batteries are much heavier and bulkier than lithium batteries for the same energy storage capacity. This can be a disadvantage for space-constrained applications.

Environmental impact: Lead is a toxic material, and improper disposal of tubular batteries can pose environmental hazards. Additionally, they vent hydrogen gas during operation, which requires proper ventilation.

Temperature: Extreme temperatures (hot or cold) can accelerate capacity degradation and reduce lifespan for both battery types.

Charging habits: Using fast charging constantly or keeping the battery at very high or low charge levels can reduce lifespan for both types.

The Lifespan of Lithium vs. Lead Acid: A Comparative Study

Overall:

A lithium inverter paired with a lithium battery will provide significantly longer backup power and overall system life compared to a setup using a tubular lead acid battery.

Here are some additional points to consider:

Lithium Battery Cycles:

Lithium battery cycles refer to the complete process of discharging a lithium battery, and then recharging it back to full capacity. This cycle repeats throughout the battery’s lifespan, but with each cycle, the battery’s capacity to hold a charge gradually decreases. Here’s a breakdown of key points about lithium battery cycles:
Impact on lifespan: The number of cycles a lithium battery can endure significantly impacts its lifespan. Most lithium batteries used in inverters and electronic devices are rated for 300 to 500 cycles before dropping below 80% of their original capacity.
Depth of discharge: The depth of discharge (DOD) refers to how much of a battery’s capacity is used before recharging. Shorter discharge cycles (using less of the capacity) contribute to a longer lifespan. For example, discharging a battery to 50% and then recharging it counts as half a cycle.

Factors affecting cycles: Several factors can influence the number of cycles a lithium battery experiences:

Depth of discharge: As mentioned earlier, shallower discharges contribute to more cycles.
Temperature: Extreme temperatures, both hot and cold, can accelerate capacity degradation and reduce cycle life.
Charging habits: Constantly using fast charging or keeping the battery at very high or low charge levels can also reduce cycles.

The Lifespan of Lithium vs. Lead Acid: A Comparative Study Here are some things to consider to maximize the number of cycles in your lithium battery:

Avoid full discharges: Try not to completely drain your battery before recharging. Ideally, stay between 20% and 80% charge level for most cycles.

Use proper chargers: Always use the charger recommended by the manufacturer to avoid damaging the battery.

Maintain moderate temperatures: Avoid exposing your battery to extreme heat or cold.

Shallow discharges preferred: Whenever possible, perform shorter discharge cycles and recharge more frequently.

By following these practices, you can optimize the number of cycles your lithium battery goes through and extend its overall lifespan.

Depth of Discharge: Lithium batteries can be discharged deeper (around 80%) without harming their capacity, unlike tubular batteries which are limited to around 50% depth of discharge.

Maintenance: Lithium batteries require minimal maintenance, while tubular batteries need regular topping up of distilled water.

Key Takeaways lithium batteries offer a significantly longer lifespan compared to lead-acid batteries, making them a more cost-effective choice in the long run. Lithium batteries can be discharged deeper without impacting their lifespan as much as lead-acid batteries, providing more usable backup power. Both lithium and lead-acid batteries benefit from practices that minimize the depth of discharge, avoid extreme temperatures, and use proper charging methods.

The Lifespan of Lithium vs. Lead Acid: A Comparative StudyIn conclusion, while the inverter itself might have a similar lifespan regardless of the battery type, the choice of battery significantly impacts the overall system’s life expectancy and performance. Lithium batteries offer a clear advantage in terms of lifespan and reliability.https://suvastika.com/lithium-inbuilt-battery-ess-2500/
