Gel battery

The Benefits of a Gel Battery

Gel batteries use silica gel to suspend the battery’s electrolyte, eliminating the spilling that plagues wet cell lead-acid batteries. They are also resistant to vibrations that harm wet cells, making them a great choice for items such as four-wheelers.

These batteries are less sensitive to overcharging than flooded lead-acid batteries, but they still need to be charged slowly and low. They also require one-way safety valves to vent internal gases and recombine back into water.


The most obvious drawback to gel batteries is their high price. This is mainly due to the fact that they are more difficult and time-consuming to manufacture than traditional lead acid batteries, as they must be fully charged before being used. This can add up to a significant amount of extra money for the average consumer, which is one of the main reasons why some people are hesitant to switch to a gel battery.

Additionally, gel batteries have to be charged at a lower voltage than regular lead-acid batteries. This is done to prevent overvoltage, which can damage the battery and decrease its lifespan. While these are some major drawbacks to gel batteries, they do offer a number of benefits that can offset these limitations.

They are great for long-term power applications that require a consistent flow of energy and can withstand heat conditions. They are often found in golf carts, marine applications, and uninterruptible power supplies (UPS). Additionally, they can be used in smaller spaces where ventilation is limited. They are also suitable for emergency use, such as in the event of a power outage. Because they are sealed, they are safe from spillage and do not require maintenance or testing like flooded batteries. Additionally, they are less susceptible to corrosion. This makes them an excellent choice for off-grid solar systems.

Longer Lifespan

The thixotropic gel electrolytes used in Gel batteries make them leak-proof and resistant to the effects of extreme temperatures. As such, they can be safely used in any environment and Gel battery require less maintenance than traditional lead-acid batteries. In fact, they have four-times the lifespan of a lead battery when adequately charged.

Moreover, Gel batteries have a longer cycle life and higher efficiency than flooded or AGM alternatives. This is mainly due to their thicker plates which allow them to store more energy per unit volume. As such, they are better suited for deep cycling applications.

However, it is important to note that GEL cells should only be used with chargers that support a constant voltage charging cycle. Leaving them on a taper charger can cause the electrolytes to form voids, leading to failure and reducing their performance.

Furthermore, the water levels in a Gel battery should be checked regularly to ensure that there is enough moisture inside to prevent drying out. This is especially important for emergency kits as it will keep the battery ready for when needed. In addition, the battery should be inspected for corrosion. Corrosion could indicate that the battery is leaking and will need to be replaced immediately.

Less Risk of Leakage

Gel batteries do not leak and offer a lot of resistance to vibration. They are also much more stable, so they do not have the same decline in voltage that flooded batteries experience. This means they are ideal for power wheelchairs and other transportation equipment.

The reason for this is that they are made of a mixture of Jell-O like acid that reduces the movement of the acid inside the battery. This makes the battery more resilient to vibration and heat variations, which can damage wet cell batteries. They are also less likely to suffer from sulfation, which is the process of the battery losing its ability to hold a charge.

Another great benefit of gel batteries is that they produce minimal fumes, making them more suitable for use start-stop car battery in restricted ventilated spaces. Additionally, they can be tipped over or even dropped without the risk of leaking acids. This makes them safer to handle, and it also helps to prolong the life of the battery.

However, gel batteries require a special charger that is compatible with them. They need to be charged at a constant voltage so that the electrolytes do not liquefy. They are also more susceptible to high voltage spikes than other batteries, so they should not be left on the charger for too long. This could result in voids within the electrolyte and reduce the lifespan of the battery.

Environmentally Friendly

A gel electrolyte is used to replace the free flowing acid of a traditional lead battery. This mixture of Jell-O like acid is sealed in a battery container during production, which makes it maintenance-free. Gel batteries can be used in a variety of environments without the need for regular topping up with distilled water, making them very useful in marine trolling applications or solar power electricity storage systems.

Gel batteries produce very little gas and fumes during use, so they can be installed in places with limited ventilation such as residential homes. They are also much safer than conventional lead-acid batteries as they don’t contain any corrosive materials.

Due to their solid build, Gel batteries are resistant to vibration and impact, so they perform well in a range of applications including four-wheelers. They are also able to withstand deep discharges, so they will provide consistent power throughout the cycle.

Due to their safety and low maintenance requirements, Gel batteries are ideal for a wide range of applications including solar energy storage, electric vehicles, marine trolling, and RVs. They are even used to provide backup power for computers and ventilators in health facilities. When used with smart chargers, they can be charged at a lower rate than traditional lead-acid batteries to reduce the risk of overvoltage. A good quality Gel battery can last up to 15 years when properly maintained.
