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.
This is a gel cell battery charger circuit using lm317.
This circuit requires a regulated 10v dc front end capable of supplying 2 amps electric current you should build this kind of power supply first.
Begins the charge period at 240ma and at full charge switches automatically to a float condition trickle charge of 12ma read more.
Noco genius1 1 amp fully automatic smart charger 6v and 12v battery charger battery maintainer and battery desulfator with temperature compensation.
To use the charger connect your wall wart to the input and plug it in.
The circuit in figure 1 was designed specifically for 12 volt gel cells.
While the circuit is running the led indicates.
Step 2 turn on the charger and charge the battery until the voltage on the terminal reaches 2 40 to 2 45 volts per battery cell 14 4 to 14 7 volts on a 12 volt battery at 58 degrees fahrenheit 20 degrees celsius.
When a discharged gel cell is connected the charger goes into a fast charge mode at a fixed rate of 400 ma.
We know a gel cell battery is a vrla valve regulated lead acid battery with a gelified electrolyte and this type of batteries are maintenance free batteries.
After the chip detects the voltage leveling off or when 4 1 2 hours has elapsed.
This 12 volt gel cell battery charger.
Because it is a lower voltage charging adjust the voltage of 13 4v.
It can extend the life of the gel cell battery.
This circuit can charge gel cell battery with reverse current and overcharging protection.
Above diagram is the schematic of 6v gel cell battery charger.
If the battery needs a fair amount of charging the led will go out.
