Gel Cell Battery Charging Requirements

Charging an agm battery.

Gel cell battery charging requirements.

Provided that the charging source is regulated at the proper float voltage the battery will establish its own current level and will be maintained in a fully charged condition. The constant current charge rate is regulated to keep the battery from overheating then the charger switches to float charge. A gel battery can be kept for extended periods of time on a float charge. The gel cell battery excels in slow discharge rates and slightly higher ambient operating temperatures.

When attempting to charge a gel battery with a lead acid charger you must ensure the peak charging voltage does not exceed 14 7 volts which would result in dried non conductive gel. A gel battery compatible smart battery charger is best for charging a gel cell battery. Step 1 attach the lead acid battery charger to your gel cell battery connecting the red cable to the positive terminal and the black cable to the negative terminal. In this mode the battery is connected to a constant voltage source of 2 25 to 2 30 volts per cell 13 5 to 13 8 volts for a 12 volt battery at 20 c.

The battery charger being used to recharge the battery s must be. The peak charging voltage for gel batteries is 14 1 or 14 4 volts which is lower than a wet or agm type battery needs for a full charge. Due to its design an agm. Gel batteries generally require a specific charge profile and a gel specific or gel selectable or gel suitable charger is called for.

A valve regulated lead acid vrla battery commonly known as a sealed lead acid sla battery is a type of lead acid battery characterized by a limited amount of electrolyte starved electrolyte absorbed in a plate separator or formed into a gel. Proportioning of the negative and positive plates so that oxygen recombination is facilitated within the cell. Since gel batteries never spill they are sometimes referred to as non spillable batteries dry cell batteries or maintenance free gel batteries. In this video we highlight the differences in bulk absorb and float charging agm flooded and gel deep cycle batteries.

One big issue with gel batteries that must be addressing is the gel charge profile. The batteries are often used in motorcycles wheelchairs and radio communications. And the presence of a.
