12V18AH GEL BATTERY

A gel battery, also known as a gel cell battery, is a type of valve-regulated lead-acid (VRLA) battery. It is designed to be maintenance-free and offers a higher level of safety compared to traditional flooded lead-acid batteries. Gel batteries are commonly used in applications where deep cycling and reliable power storage are required, such as in renewable energy systems, electric vehicles, telecommunications, and uninterruptible power supplies (UPS).

The main characteristic of a gel battery is the use of a gel electrolyte, which is a thick, jelly-like substance composed of a sulfuric acid solution mixed with silica fume. The gel electrolyte immobilizes the electrolyte within the battery, preventing it from spilling even if the battery is tipped or damaged. This design makes gel batteries spill-proof, leak-proof, and resistant to vibration.

The gel electrolyte also has the advantage of providing a more uniform distribution of the electrolyte within the battery, reducing stratification. Stratification occurs when the acid concentration is higher at the bottom of the battery and lower at the top, which can result in reduced battery performance. The gel electrolyte helps to minimize this effect and improves the battery's overall performance and longevity.

Gel batteries are known for their deep cycling capabilities, which means they can discharge a high percentage of their capacity while maintaining a long service life. They have a lower self-discharge rate compared to flooded lead-acid batteries, retaining their charge for longer periods when not in use. Gel batteries also exhibit good tolerance to high temperatures, making them suitable for use in harsh or extreme environments.

It's important to note that gel batteries require specific charging parameters and should be charged using chargers designed for gel batteries or with charging algorithms that are compatible with gel cell technology. Improper charging can lead to reduced battery life or even damage.

Overall, gel batteries provide a reliable and durable energy storage solution, particularly in applications that demand deep cycling, safety, and maintenance-free operation.
