The charge current for Gel batteries should be around 20% of the battery’s 20-hour rate for both Bulk and Absorption charge phases. In situations where charge times are not limited, such as in grid-connected backup applications, a charge rate of 10% is acceptable.
From this all follows the main rule for charging a gel battery: in no case should the charge voltage be exceeded. The norm here, as for conventional car batteries, is 14.4 V. The maximum is -14.5 V. If you charge the battery and apply more voltage to it than indicated, this will lead to the electrolyte peeling off the lead plates.
Only charge AGM or GEL batteries using a genuine and reliable temperature-sensing voltage-regulated charger. Never use a constant current charger without voltage regulation! Charging Current or Amps is the flow of electricity. Every battery can only store, deliver or receive a certain amount of electricity. Voltage is electrical pressure.
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.
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.
GEL batteries maintain absorption charge voltage at no more than 2.35 +/- .5 volts per cell and float voltage at no more than 2.25 volts per cell at 25°C/77°F. AGM batteries maintain absorption charge voltage at no more than 2.45 +/- .5 volts per cell and float voltage at no more than 2.27 volts per cell at 25°C/77°F.
