Otherwise, you can apply the constant voltage charging method (at 14.4V). Regardless, charge a gel battery slowly and steadily, continuously monitor the charging process for charge and temperature to prevent overcharging, and use desulfation mode if the battery has no charge left. Follow the manufacturer’s precise instructions, if provided.
To determine the voltage the gel cell charger circuit needs to produce, multiply the number of cells in your battery by 2.3, then add 5 volts to account for circuit losses. For instance, to charge a 12-volt battery, you'll need a 19-volt unregulated IC supply.
When, at a voltage of 14.4 V, the charge current drops to 0.1-0.3 A, the gel battery can be considered fully charged. In the event that the charger is manually controlled, it is advisable not to miss this moment so that the recharge does not go. Automatic chargers will turn off the charge on their own.
Gel cell batteries function differently during charging. Once a full charge is reached, the circuit changes over from constant current mode to a constant voltage mode. This changeover from constant current to constant voltage is crucial for gel cell batteries to prevent overcharging. A gel-cell battery is quite similar to a contemporary automobile battery.
The indicators should not be higher than indicated in paragraphs 4 and 5. When, at a voltage of 14.4 V, the charge current drops to 0.1-0.3 A, the gel battery can be considered fully charged. In the event that the charger is manually controlled, it is advisable not to miss this moment so that the recharge does not go.
Typical gel-cell batteries have voltage specs ranging from 2 to 24 volts. The Ah (Amp-Hours) rating relates to the quantity of current which could be supplied by the battery within a length of time. For instance, a battery may be specified with 2 volts and 30 Ah. Gel-cell batteries are available with voltage specs that may vary from 2 to 24 volts and in Ah capacities which range from 1.2 to 120 Ah.
