Characteristics of GEL batteries

Gel batteries are one of the most used types of batteries thanks to their excellent performance and advantages compared to other types of batteries. Gel batteries are characterized by being made with a gelled electrolyte and are totally sealed so they do not release any type of liquid in the event of the battery overturning. They are mostly intended for small and medium-sized solar installations that need a long-term battery. Gel batteries are characterized by their deep discharge cycles as they can reach up to 800 life cycles.

In AutoSolar you can find different types of gel batteries such as: 6V GEL batteries , 12V GEL batteries , 24V GEL batteries , 48V GEL batteries . GEL batteries belong to the lead acid family and their great difference from these is the state of the electrolyte, which in the case at hand is much more gelled, as its name indicates, and is less harmful. This implies greater resistance to vibrations and high temperatures as well as less evaporation than in conventional lead acid batteries. It’s all about the batteriesmost effective on the market with excellent functionality, being the most used for photovoltaic solar installations.

Common uses of GEL Batteries

Gel batteries have a good value for money , they are a little more expensive than conventional lead acid batteries but this is compensated by their high guarantee of operation and durability. GEL batteries are indicated for isolated installations or for uses where the role of the batteries is essential. They are one of the most demanded products for solar installations since they do not require maintenance and it is not necessary to regularly check the levels of acid inside them.

It is recommended that you keep the Gel battery in its natural position, that is, with the terminals facing up to extend its useful life and achieve maximum efficiency.

Questions and answers of GEL batteries vs. AGM batteries

Does a GEL or an AGM battery last longer?

An AGM battery is a sealed battery with the electrolyte absorbed in fiberglass separators. Inside there is liquid sulfuric acid soaked in the fiberglass of the separator. While a GEL battery has an electrolyte that is silica gel and the separator material is the same as in an AGM, fiberglass.

What advantages does a GEL battery have over an AGM?

GEL batteries charge more quickly, if stored, maintain a charge longer, have greater reliability in partial states of charge (PSOC), better performance at low temperatures and have a greater current delivery capacity.

Which one has more durability?

Normally, a GEL battery lasts longer than an AGM battery, and, although it depends on the brand and model, it can be said that it has a 30% longer life in number of cycles. For certain very intensive applications (golf carts, electric vehicles, etc.) the choice of GEL is almost mandatory.

Can they be installed in any position?

Both can be placed in any position, lying down or on their side, and function correctly, although it is recommended that they be placed in their natural position to maximize their useful life and promote correct operation.

Is a special charger necessary?

We will need a charger or regulator that allows the selection of the type of battery, nowadays, all allow between the choice between flooded (open lead-acid), sealed (AGM), and GEL. AGM and GEL batteries have lower charge voltages than lead acid batteries, and choosing a higher charge curve than necessary can swell them and cause premature failure, and they should not be equalized.

What are the usual applications of an AGM or GEL batteries?

AGM batteries are normally used for UPS systems, telecommunications, UPS, medical and alarm systems, scales, medium-low demand solar systems, start-stop vehicle starting, boats, caravans. While GEL batteries should be used for telecommunications systems, railway beacons, caravans, boats, wheelchairs, electric scooters, scooters, etc. For the photovoltaic sector, both batteries are equally valid.

GEL battery warranty

GEL batteries have a two-year manufacturer’s warranty from the time of purchase of the GEL battery and provided that the use of the GEL battery has been correct and the manufacturer’s specifications have been followed. Among the most important specifications, it stands out that GEL batteries should not be connected in parallel , since parallel connection weakens the useful life of solar batteries and irreparably reduces their efficiency.

Advantages of GEL Batteries

In AutoSolar you can find GEL Batteries with the best characteristics of reputable brands in the international market. You can purchase batteries with the best guarantee and confidence and with unique advantages. They are characterized by being maintenance free and much cleaner than conventional ones since they are free of lead and possible acid liquid spills are avoided. Their self-discharge rate is minimal and they can retain 80% of their charge after six months without using it.

Configuration of the charging stages of the different battery models (Lead-Acid, AGM and GEL)

Below we are going to show the standardized charging voltages of the different charging phases of the different battery models ( lead acid , AGM and GEL). The charging voltages can be found in the technical sheets depending on the manufacturer and the battery technology, it is always advisable to check these charging voltages to ensure proper operation. Charging batteries with incorrect voltages leads to a rapid loss of useful life, it is very important to reach 100% charge and never overcharge the battery, for this we must adjust the different stages of charge depending on the type of technology ( lead acid , AGM or GEL).

As can be seen in the table, the AGM and GEL battery models do not have an equalization charge stage.
