Gel Battery

What is Gel Battery ?


A gel battery is a valve regulated, maintenance free, lead acid battery.  Gel batteries are extremely robust and versatile. These type of batteries produce few fumes and can be used in places without much

How does a gel battery work?

A gel battery s a valve regulated, lead acid battery in which a pre-determined quantity of an electrolyte, together with sulphuric acid is combined with silica fumes.

This chemical reaction results in an immobile, gel like mass giving these batteries their name.

The gel batteries are virtually maintenance free as they uses one-way open valves that allow the internal gasses to recombine into water, hence removing any need to check to top up distilled water or monitor water level.

Gel batteries are extremely robust and versatile. They are safe to be installed in places where ventilation is limited, due to fact that they have a very low (virtually zero) gas/fumes production, which means you can even install the batteries inside your home.

Carefully select the right charge controller for your gel batteries

Special consideration should be given when selecting chargers for gel batteries as they get charged at lower voltages. Overvoltage can lead to failure and reduced performance.

Sometimes the term GEL cell is commonly referred to sealed, maintenance free batteries and marked as a setting on charge controllers.

This can be confusing and may lead to the wrong selection of chargers or incorrect settings while charging.

In case of using other charging methods like alternators, proper regulators must be installed to keep control over charging voltage. General charging voltage range of batteries is 14.0 volts to 14.2 volts, and float voltage range 13.1 volts to 13.3 volts.

Advantages of Gel batteries

Gel Batteries are becoming increasingly popular for solar systems due to the following reasons:

Best suited for Deep cycle applications and their life is generally in the 500 to 5000 cycles range

Maintenance free

Spill proof

Minimal corrosion therefore compatible with sensitive electronic equipment

Rugged and vibration-resistant

Very safe as less risk of sulphuric acid burns

Lowest cost-per-month (cost / months of life)

Lowest cost-per-cycle (cost / life cycles)
