What is a Gel Battery?

A gel battery is a valve-regulated, maintenance-free lead acid battery. Gel batteries are highly durable and versatile. These batteries have few emissions and can be utilized in locations with limited ventilation.

What Is A Gel Battery Used For?

Gel cells are often found in cell phones, camcorders, motorcycles, and ships. It’s also used in high-end automobiles. Because of its low maintenance aspect, users do not have to add water to the battery every now and then to maintain proper electrolyte levels.

How Does A Gel Battery Work?

The electrolyte in a gel battery is a thick, heavy gel. The lead plates are submerged in the gel.

When the battery is charging, the gel becomes electrically charged and when the battery is discharging, the gel loses its charge.

The gelling agent used in making this battery is silica fume.

Advantages and Disadvantages of Gel Batteries

Advantages Of Gel Batteries

  • Maintenance free.
  • Flexible installation.
  • Longer lifespan in extreme weather.
  • Long standby life.
  • Longer shelf life.
  • High rate performance.

Maintenance free

The main advantage of using a gel battery is that it is maintenance-free. You don’t have to add water to it every now and then like you would with other types of lead acid batteries.

Additionally, it doesn’t require as much ventilation as other types of batteries, making it ideal for use in locations with limited ventilation.

Flexible installation

Another advantage of a gel battery is that it can be installed in a variety of positions. This flexibility makes it ideal for use in applications where space is limited.

Longer lifespan in extreme weather

Gel batteries also have a longer lifespan than other types of batteries when used in extreme temperatures.

This makes them ideal for use in applications where the temperature is frequently below freezing or above 100 degrees Fahrenheit.

Long standby life

Gel batteries also have a long standby life, meaning they can hold a charge for extended periods of time without being used.

This makes them ideal for use in applications where the battery will not be used for extended periods of time, such as emergency backup power.

Longer shelf life

Gel batteries also have a longer shelf life than other types of batteries, meaning they can be stored for extended periods of time without losing their charge.

This makes them ideal for use in applications where the battery will not be used for extended periods of time, such as emergency backup power.

High rate performance

Finally, gel batteries have a high rate performance, meaning they can discharge and recharge at a higher rate than other types of batteries.

This makes them ideal for use in applications where the battery will be used frequently and needs to be able to hold a charge for extended periods of time.

Disadvantages Of Gel Batteries

  • High initial cost.
  • In case of overcharging water cannot be refilled.
  • Special chargers and regulators are required.
  • Hot temperatures can affect them

High initial cost

Gel batteries cost considerably more than other types of lead acid batteries. This high initial cost can be a barrier to entry for some applications.

In case of overcharging water cannot be refilled

If a gel battery is overcharged, the electrolyte will boil off and the battery will be damaged. Once this happens, the battery cannot be refilled with water and must be replaced.

Special chargers and regulators are required

Gel batteries require special chargers and regulators that are designed to charge them properly.

These chargers and regulators can be expensive and may not be available for all applications.

Hot temperatures can affect them

Finally, hot temperatures can affect gel batteries, causing the electrolyte to evaporate and the battery to be damaged.

This can be a problem in applications where the temperature is frequently above 100 degrees Fahrenheit.

How To Charge A Gel Battery

You can charge a gel battery by using a float charger, which is a type of charger that is specifically designed for use with gel batteries.

You can also charge a gel battery by using a standard lead-acid battery charger, but you will need to set the charger to the gel setting before connecting it to the battery.

How To Discharge A Gel Battery

I recommend discharging a battery to no lower than 50% DOD, with a maximum of 80%. If you discharge the battery to 50% of its capacity instead of 100%, it will generate 40 percent more amperes over the life of the battery.

How to desulfate a gel battery

Filler caps must be removed from the batteries. They should then go through a thorough examination, culminating with a cross-check of the water liquid electrolyte level. If required, distilled water should be added.

After this, you must charge the battery at 10 amps for 24 hours while measuring the voltage. If the voltage doesn’t rise above 12.6 volts, then the battery is sulfated and must be replaced.

Agm Gel Battery

What is an AGM Battery?

Absorbent Glass Mat car batteries (AGM) were developed in the 1970s as a maintenance-free, spill-proof alternative to flooded lead-acid batteries.

AGM batteries use an absorbent glass mat (AGM) separator between the positive and negative plates that absorbs and contains the electrolyte.

This design prevents the escape of electrolyte from the battery, even if it is damaged, making AGM batteries leak-proof and spill-proof.

AGM batteries are also sealed, meaning they can be used in any orientation without leaking or spilling.

This makes them ideal for use in applications where the battery may be subject to vibration or movement, such as in a car or boat.

FAQs

Which is better AGM or gel battery?

AGM batteries allow for quicker charging and improved performance under heavy-load conditions because they have a lower internal resistance. AGM Batteries will most likely outperform GEL in cooler climates and be less expensive as a reliable power source.

Can an agm battery be fully discharged?

Batteries that are designed to be utilized for extended periods of time (deep cycle A.G.M.) can only be discharged down to 50%, whereas the lead acid battery may be discharged to 80%. As a result, each charge of the lead acid battery allows appliances to operate for longer amounts of time.

Can agm battery be mounted on its side?

Yes, both AGM and gel batteries can be mounted on their side. However, the should not be mounted upside down as this can damage the battery.
