Gel Cell Battery Charger Circuit

As the battery terminal voltage starts to reach the float charging range the led will begin to light.

Gel cell battery charger circuit. This circuit can charge gel cell battery with reverse current and overcharging protection. 4 5 out of 5 stars 3 035. Place the battery on the gel cell battery charger by following the manufacturer s instructions for insertion. It can extend the life of the gel cell battery.

Because it is a lower voltage charging adjust the voltage of 13 4v. While the circuit is running the led indicates. This 12 volt gel cell battery charger. This is a gel cell battery charger circuit using lm317.

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. Simple 12 volt gel cell battery charger circuit constructed by using few easily available components. 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.

If the battery needs a fair amount of charging the led will go out. When a discharged gel cell is connected the charger goes into a fast charge mode at a fixed rate of 400 ma. Above diagram is the schematic of 6v gel cell battery charger. 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.

It can charge any size of the gel cell batteries with the charging current 300ma 650ma and 1 3a. 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. Begins the charge period at 240ma and at full charge switches automatically to a float condition trickle charge of 12ma read more. Next attached the output to the gel cell battery to be charged.

After the chip detects the voltage leveling off or when 4 1 2 hours has elapsed. The following scheme diagram is the battery charger circuit for 6v gel cell battery type only. Noco genius1 1 amp fully automatic smart charger 6v and 12v battery charger battery maintainer and battery desulfator with temperature compensation. The led should be lit.

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.
