| 6V lead Acid battery charger circuit |
I recently repaired a emergency lamp which was 3years old and I was amazed that the 6V Lead Acid Battery was in a good shape , not overcharged not over heated and have a great performance .The customer said he never changed the battery since he brought it .I was amazed by the simplicity of the charging circuit then I decided to redraw the charging circuit .And here is the circuit diagram I came up with.

Part list -
J1 - 2pin connector to connect the Battery
J2 - 2pin connector for 12vdc input
R1 - 5ohm 3W> Ceramic resistor
D1,D2,D4,D5 - 1N4001 Diodes
Q1 - 9012 PNP Transistor
D3,D6 - LED indicatiors (Charging /Charged)
R4 - 330ohm 0.25w resistor
R3,R2 - 1.5K 0.25w resistor
C1 - 100uf /16v Electrolytic capacitor
Feedback
Mr.Lahiru from Sri Lanka have successfully built the 6V Lead Acid Battery Charger Circuit on a dot board and stated that it works perfectly .Here is his circuit -
