Gel Cell Battery Charger Circuit

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.

Gel cell battery charger circuit.

It can charge any size of the gel cell batteries with the charging current 300ma 650ma and 1 3a. This is a gel cell battery charger circuit using lm317. As the battery terminal voltage starts to reach the float charging range the led will begin to light. The following scheme diagram is the battery charger circuit for 6v gel cell battery type only.

Begins the charge period at 240ma and at full charge switches automatically to a float condition trickle charge of 12ma read more. The led should be lit. Next attached the output to the gel cell battery to be charged. R1 22 ohm 1w r2 270 ohm r3 220 ohm r4 715 ohm 1 r5 3 57k 1 r6 1 40k 1 r7 1 47k 1 c1 0 1uf ceramic c2 0 1uf read more.

While the circuit is running the led indicates. It can extend the life of the gel cell battery. 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 circuit can charge gel cell battery with reverse current and overcharging protection.

1 16 of over 1 000 results for gel cell battery charger best seller in powersports battery chargers. 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. The circuit in figure 1 was designed specifically for 12 volt gel cells. Above diagram is the schematic of 6v gel cell battery charger.

Because it is a lower voltage charging adjust the voltage of 13 4v. After the chip detects the voltage leveling off or when 4 1 2 hours has elapsed. 4 5 out of 5 stars 3 035. This 12 volt gel cell battery charger.

To use the charger connect your wall wart to the input and plug it in. Simple 12 volt gel cell battery charger circuit constructed by using few easily available components. If the battery needs a fair amount of charging the led will go out. 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.
