What is a 12V Gel Battery?

A Gel battery or also called GEL VRLA (Valve Regulated Lead Acid) battery is simply a lead-acid battery in which the electrolyte has been immobilised using thixotropic silica gel in order to recombine hydrogen and oxygen. It has a sealed construction with pressure release valves to prevent gases from escaping. The use of silica gel to immobilize the acid is what gives its name – Gel Battery.

What is GEL Battery Technology?

Because the electrolyte is no longer in a fluid state, due to being gellified into a finely textured thixotropic silica gel, the gases produced at the plates are not free to form bubbles and rise to the top surface. Instead, they are trapped in the immobilised silica gel matrix and forced to travel to the opposite poles by the pressure gradient produced when on charge. In a free liquid, this would be impossible.

A 12V gel battery is a type of rechargeable battery that uses gel electrolyte instead of liquid electrolyte. The gel electrolyte is made by adding a gelling agent to the electrolyte solution, which makes it thicker and more viscous. This helps to prevent leakage and spillage, making gel batteries safer and more convenient to use than traditional liquid electrolyte batteries. Gel batteries are often used in applications where high reliability and long service life are important, such as in standby power systems, solar power systems, and electric vehicles. They are also commonly used in marine and recreational vehicle applications due to their ability to withstand vibration and shock. As the name suggests, a 12V gel battery has a nominal voltage of 12 volts, which makes it suitable for use in many different types of devices and equipment.

Designed by Dr Wieland Rusch of Germany – Manufactured with precision and pride in India. We manufacture the complete Tubular Gel batteries, lead plates, gel electrolyte, and all its components in house ensuring a high level of quality without having to depend on outside vendors.

12V Gel Cell Battery uses & applications: 12V deep cycle Gel Batteries are suitable for Solar battery backup, UPS & Inverter systems, Switchgear & controls, Banks, Insurance & Office power backup, Traffic management systems

Microtex Eternia deep cycle gel battery 12v – valve-regulated (VRLA) with high power density using thixotropic silica gel are available in a wide range in 12V monoblocks from 100Ah to 200Ah. VRLA 12v GEL Battery with longer cycle life for the UPS & Inverter industry from Microtex are sealed maintenance-free batteries and come with assured quality. Microtex incorporates battery research and design from years of its own experience and that of reputed European Battery Scientists. Microtex 12v GEL battery series – delivers trouble-free performance with an ultra-long life on float applications. They are supplied in factory charged condition ready for use.

What is VRLA Battery?

VRLA stands for Valve Regulated Lead Acid battery. It is a characteristic of a 12V GEL Battery.

What is the advantage of a gel battery? 12V Gel Battery vs lead acid

12V Gel batteries are sealed maintenance-free batteries. Microtex offers this with Tubular Plate Technology. Tubular plates are very robust in construction. Unlike a flat plate, the tubular plate will not shed in the service life of the battery. Read all about tubular plate technology in our blog pages.

Lead-acid referred to here usually means flooded lead-acid batteries. Flooded batteries require topping up periodically. Gel batteries are sealed & require no topping up. Having a design life of over 15 years, they offer the best value for money.

What are the benefits of using a 12V Gel Battery?

A 12V gel battery is a type of rechargeable battery that uses a gel electrolyte instead of a liquid one. Some potential benefits of using a 12V gel battery include:

  • Longer lifespan: Gel batteries tend to have a longer lifespan than traditional lead-acid batteries, making them a more cost-effective option in the long run.
  • Maintenance-free: Gel batteries require little to no maintenance, as they do not need to be topped off with water or checked for acid leaks like traditional lead-acid batteries.
  • High discharge rates: Gel batteries are capable of providing high discharge rates, making them suitable for use in high-current applications.
  • Safe and environmentally friendly: Gel batteries are sealed and spill-proof, reducing the risk of acid spills or leaks. They also do not emit harmful gases during charging or discharging, making them a safer and more environmentally friendly option compared to traditional lead-acid batteries.
  • Overall, if you’re looking for a reliable and low-maintenance battery option for your 12V system, a gel battery may be worth considering.

How much does a 12V Gel Battery cost, and how do I know if it's good quality?

The price for a 12V Gel Battery can vary depending on the brand and specifications. However, when it comes to determining if a battery is of good quality, there are several factors to consider.

These include the battery’s capacity, durability, maintenance requirements, and warranty. It is also important to look for batteries that meet & conform with tests and certifications by reputable organizations such as Underwriters Laboratories (UL) or the International Electrotechnical Commission (IEC). Additionally, reading reviews and checking ratings from other customers who have used the same brand or model can give you an idea of its performance and reliability. Ultimately, investing in a high-quality battery may cost more upfront but can save you money in the long run by providing better performance and lasting longer.

What precautions should be taken when using these batteries or any other type of battery that has been designed to last longer than conventional ones (e.g., deep cycle 12V gel battery)?

When using batteries designed to last longer than conventional ones, such as deep cycle batteries, it is important to take certain precautions. Here are a few tips to keep in mind:

  • Read and follow the manufacturer’s instructions carefully: Different types of batteries may have specific requirements for charging, discharging, and maintaining proper use.
  • Use the right charger: Make sure you use a charger that is specifically designed for your type of battery.
  • Check the voltage regularly: Overcharging or undercharging can damage the battery, so it’s important to check the voltage regularly to ensure that it remains within the recommended range.
  • Store the battery properly: Keep batteries in a cool, dry place away from direct sunlight or heat sources.
  • Dispose of batteries properly: When it’s time to replace your battery, be sure to dispose of it properly according to local regulations.

How long does a 12V gel battery last?

To determine how long a 12V gel battery will last, several factors need to be taken into consideration, such as the capacity of the battery in amp-hours, the load being placed on the battery, and the charging system being used. Generally speaking, a 12V gel battery with a capacity of 100 amp-hours can provide power for around 8-12 hours, depending on the load being placed on it. However, this is just an estimate and actual performance may vary depending on the specific conditions and use case. It is important to properly maintain and charge your battery to ensure optimal performance and longevity.

Battery Mistakes All 12V Gel battery Owners Need To Avoid!

How to restore 12v gel battery? How to revive 12v gel battery?

Do not mix new batteries with old batteries

12V Gel Battery reconditioning: often reconditioning an old 12V Gel battery can become quite a costly affair if you keep replacing dead batteries one by one; even the new battery will drain out rapidly as the old batteries tend to draw more out of the new one. 

12V Gel battery replacement: It is best to have an expert from the company visit you to have a thorough inspection of the 12V Gel batteries after a complete charge, compare the cell voltage, specific gravity to decide the state of charge & whether in needs to be replaced at all.

Avoid any sort of battery additives or desulfation methods

How to recondition 12V Gel batteries? 12V Gel Batteries are electro-chemical devices. All chemicals have a half-life period beyond which regeneration with chemical battery additives or desulfators for batteries have little effect, if any, temporary. 

The normal mode of failure at end of life of 12V Gel batteries are usually due to the decomposition of the positive plate and or grid corrosion. Desulfators cannot repair corroded grids. Once the positive plate decomposes, there is no magic or chemical in the world that will rejuvenate the battery. CdSO4 has been used, to give the battery a shot of adrenaline, but is highly toxic & causes problems in the recycling stream.
