What is a Gel Battery? Why Should It Be Used?

Gel batteries are a type of rechargeable battery that uses gel electrolyte to provide power and offers excellent performance. The electrolyte in these batteries is in a gelled form and is denser than the liquid electrolyte. Gel batteries are generally used in closed systems and are resistant to vibration. So, what are the advantages of gel batteries and why should they be used?

One of its most important advantages is that its acid content is in gel form. This feature allows the battery to operate in any position. Whether vertical, horizontal or sideways, gel batteries have a much lower risk of acid leakage than those powered by liquid electrolyte. This means gel batteries are safer.

Additionally, the longer lifespan of gel batteries is also a notable advantage. Since gel electrolyte does not evaporate as does liquid electrolyte, the life of the battery may be longer. In this way, gel batteries require less maintenance and need to be replaced less frequently.

It has deep discharge properties. This means the battery can store energy more effectively and operate at low voltage for long periods of time. This feature makes them preferred in applications such as solar energy systems.

What is the difference between gel batteries and other battery types?

Gel batteries use a substance in gel form as the electrolyte. This gel is a mixture between acidic electrolyte and sulfuric acid and acts as a buffer by filling the distance between the electrolyte and the plates. This structure ensures that the battery is vibration resistant and leak-proof.

First of all, it should be noted that this type of batteries has a significant advantage in terms of safety. Gel batteries are safer than liquid electrolyte batteries because they contain acidic electrolyte. There is no risk of spills or leaks as with liquid electrolyte batteries, making gel batteries a better option.

Additionally, gel batteries have high discharge rates and deep discharge tolerance. That is, they can respond quickly to intense energy demands and retain their original capacity even after being completely discharged. Thanks to these features, gel batteries are widely used in applications such as marinas and caravans.

It offers low maintenance requirements. You do not need to periodically check the electrolyte level or add additional electrolyte, as in liquid electrolyte batteries. This shows that gel batteries are a user-friendly and practical option.

How long do gel batteries last?

These batteries are especially widely used in applications such as solar energy systems, wind turbines and backup power supplies. So, how long do gel batteries last?

They typically have a longer life than traditional lead-acid batteries. Generally, when well maintained and used correctly, gel batteries can last 5 to 7 years or more. However, many factors can affect the lifespan of gel batteries.

An important factor affecting the life of this type of batteries is the conditions of use. Constantly leaving the battery fully charged or overdischarging it may shorten its life. Additionally, temperature also has a big impact on gel batteries. High temperatures can increase the internal resistance of the battery and thus reduce its lifespan. Low temperatures may negatively affect the performance of the battery.

Regular maintenance is also important. Simple maintenance such as cleaning the terminals, checking water levels and refilling when necessary can extend the life of the battery. Additionally, early detection and resolution of problems such as overcharging, deep discharge or vibration is important.

Another factor to keep in mind is that the lifespan of gel batteries may vary depending on the brand and quality. Choosing a quality gel battery is important to achieve a longer lifespan. Therefore, it is important to choose a high-quality gel battery produced by a reliable manufacturer.
