Sealed Agm Battery Is Not A Gel Battery

  　   What is the difference between AGM and gel battery?

  　　Both types of batteries are sealed, and valve-regulated batteries can be used in any position. The difference lies in the way the electrolyte is fixed. In the case of the newer AGM (absorbent glass mat) of the two technologies, the electrolyte is absorbed by a glass fiber separator that acts like a sponge. In a gel-type battery, the liquid electrolyte becomes a gel immediately after filling the battery. Gel batteries use different types of non-absorbent separators. Due to this design, the gel battery cannot provide the same power as the AGM battery of the same physical size. For example, a 12V 100AH ​​AGM battery, and in the case of the same size, a gel battery can only reach 84AH.

  　　Sealed AGM Battery (absorbent glass mat) is a specially designed glass mat for wicking battery electrolyte between battery plates. The AGM battery only contains enough liquid so that the pad is wetted by the electrolyte, and if the AGM battery is damaged, there is no free liquid leakage.

  　　The gel cell battery contains a silica-type gel in which an electrolyte is suspended. This thick paste-like material allows electrons to flow between the plates, but if the casing is broken, it will not leak in the gel battery.

  　　Generally, AGM batteries are mistaken for gel batteries. Both batteries have similar characteristics. For example, they do not sprinkle water, can be installed in any location, have a low self-discharge rate, can be used safely in limited ventilated areas, and can be safely transported by air or ground without special treatment.

  　　When a large number of amperes may be required, AGM batteries are preferred. In most cases, charging can be done by using a high-quality standard battery charger. If most AGM batteries do not discharge more than 60% between charges and/or are fully charged every 3-6 months, the life expectancy (measured in cycle life or years) is still excellent.

  　　Gel batteries cannot provide the same power as AGM batteries of the same physical size. However, Gel Cell has an excellent performance in terms of slow discharge speed and slightly higher operating temperature, as well as excellent deep cycle capability. Gel battery batteries are considered Sealed Deep Cycle Battery due to their structure. One of the major problems that gel batteries must solve is the charging characteristics. Gel batteries must be charged correctly, otherwise, the batteries may fail prematurely. For the maximum charging current limit, please refer to the specification table. It is strongly recommended to use a gel battery charger.
