6V Gel Cell Charger Circuit

6V


This is the diagram of 6V Gel Cell charger. The schema is using NE555 timer as oscillator and TPI31T switching transistor. The schematic diagram designed by Tony Van Roon.

Parts List:
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 = 100nF
C2 = 100nF
D1 = 1N4001
T1 = TIP31A, B, C (or equivalent)
U1 = Timer IC NE555V (or equivalent)
S1 = Toggle switch, ON-OFF
* Resistors type are carbon, 1/4 watt, 5% tolerance, unless otherwise indicated.
