AGM VS. Lithium-ion Batteries: Which Is Better?

What Is an AGM Battery?

What Is an AGM Battery? Definition and How It Works

AGM batteries, also known as absorbed glass mat batteries, belong to the family of lead-acid batteries in which the electrolyte is absorbed in a glass fibre mat separated between the plates of the battery, which is a fundamental shift from the traditional lead-acid batteries where routine checking is not required, and the battery does not operate with the worries of any spills or leakage for the battery.

AGM Batteries are made in such a way that they produce energy by bringing together lead dioxide and sulfuric acid, creating a chemical interaction that fuels their working. Due to the structure made of fibreglass mats, the electrolyte, and therefore the batteries, are safer and more durable than traditional batteries will be the case. Their sealed structure becomes the best solution for activities where reliability and long-term operation are important parameters: off-grid solar schemes, marine applications, and contingency power for critical systems.

Another remarkable characteristic of AGM batteries is their capacity for large power bursts, i.e., starting current, which makes them useful for a broad range of starting and other systems of vehicles. Only because of their low energy density in relation to other modern options is their employment in high-capacity situations restricted. AGM battery's self-discharge values remain relatively low, enabling the devices to be used as standby power for a long time.

Pros of AGM Batteries

• No Maintenance Required: AGM batteries do not call for water replacement, as do conventional lead-acid batteries. In other words, maintenance requirements are considerably lower.

• No Capacity Leak: AGM batteries can be installed in a wide range of positions due to their sealed capacity, which prevents any leaking.

• Rapid Discharge: An AGM battery can easily provide vehicles and equipment needing to start up in quick intervals with short periods of high energy.

• AGM Batteries vs Others: Another advantage of AGM batteries is that compared with lithium-ion batteries, a lower price is implemented, which is useful for specific commitments.

• High Energy Retention: AGM batteries are suitable for standby and backup applications as they have an impressive capacity to retain charge when not in use, as well.

Cons of AGM Batteries

AGM batteries can appear to have a downside when it comes to discharging current.

• Ample Space Required: It is clear to many users that AGM batteries take a significant amount of Space and weight to be stored due to their specific energy intensity to width ratio. Thus, their capacity is limited. In comparison to lithium-ion batteries, they are less energy efficient and less densely packed.

• Expensive To Use: AGM batteries serve as the cheaper option; however, when it comes to regularly using them, costs go through the roof as they are expensive. When it comes to frequent charge cycles, their lifetime expectancy is around three to five years.

• Heavyweight: Campers and such can face challenges with mobile usage of AGM batteries as their overall lead content is extremely high, making them considerably heavy.

• Limited depth of discharge: When AGM batteries are deeply discharged and whenever it happens, their lifespan increases and performance efficiency decreases.

• Have a slow charging rate: In time-oriented practices, AGM batteries are inefficient in charging compared to lithium-ion batteries, which are slow.

AGM Batteries are affordable and more robust but are not efficient or long-lasting. So, if your application needs foldable energy and spill-free use, AGM batteries are ideal for you since they are cheap. Still, if one is trying to decide between AGM or lithium batteries, considering the shortcomings of AGM is pivotal.

We have been using AGM batteries for decades now, and even though lithium batteries have advanced features, they remain popular as starter and marine batteries. Our collective understanding of their features or marketplace equips us to adeptly make smart choices. By comprehensively understanding the advantages and disadvantages of AGM batteries, a consumer can decide whether AGM batteries do their job or not.

What Is a Lithium-ion Battery?

What Is a Lithium-ion Battery? Definition and Working Principles

Battery-type lithium-ion made headway into the market due to its advanced technology. For the sake of simplicity, during the charging and discharging process, these batteries allow lithium ions to transfer between the anode and cathode. When combined with lightweight construction and dense energy, the end result creates an effective energy delivery system, which is crucial for portable devices.

Lithium-ion batteries are used in many devices and systems, such as smartphones, laptops, electric cars, and even power packs. The recent developments brought about by chemistry, such as LiFePO4 (Lithium Iron Phosphate), have made them safer, longer-lasting, and even more reliable than before. Their development and robustness of construction allow for their large-scale use — from miniature hearing devices to wide-range grid energy storage systems.

Lithium-ion batteries work by lithium ions moving between the anode and the cathode through a conductive electrolyte through conductive materials for quick energy transfer while the design is sealed for security and durability. Additionally, Lithium-ion batteries are less than or as optimal as lead-acid batteries because the former can work in extreme temperatures.

Advantages of Lithium-ion Batteries

• High energy density: Lithium-ion batteries can be contained in small and lightweight structures that allow the storage of high power because of dense cellular design; thus, if portable applications are concerned, then these batteries are ideal.

• Long lifespan: These batteries, with an estimated longevity of a decade or more, ensure that the initial investment is sound as there will be no issues for a number of years.

• Fast charging: Lithium-ion can be charged rapidly and does not generate high electrical temperatures, which means that the downtimes will be significantly lowered as compared to conventional batteries like AGM.

Disadvantages of Lithium-ion Batteries

• Costs more in the first place: The upfront investment in lithium-ion batteries is more expensive than in AGM batteries. However, in the long term, these more expensive batteries tend to last longer, and the cost is recovered.

The only metric that lithium-ion batteries don't perform as well as AGM in is cost, but given their longevity, the initial cost of investment more than compensates for it. From our perspective, they are a great investment. However, the cost could still, without a doubt, raise eyebrows.

• Sensitive to temperature: Some applications require protection systems in both extremely hot and cold temperatures; when both temperature extremes are reached, performance may decrease.

• Difficult to recycle: A battery's composition determines its recycling process, and these batteries have a rather complex chemical makeup, which makes them disadvantageous for the environment if not properly handled.

• Risk of thermal runaway: Occasionally, when batteries are mistreated or there are defects in the manufacturing process, the batteries tend to overheat. But with today's designs and advancements, a myriad of solutions have been introduced to help these people handle this problem on their own.

• Includes backup self-discharge: Lithium-ion backup power is a great solution for many dedicated applications; as opposed to older technologies, these batteries lose minimal charge when left unused.

In comparison with AGM and lithium-ion batteries, lithium-ion batteries are the best option for almost all contemporary power requirements. If usage is frequent and mobile reliable, then the slightly higher cost is offset by the high energy density, efficiency and long-term life of the battery. They are likely to remain dominant in the energy storage market due to their versatility across different industries.
