Introduction: How to Make Automatic 12V Battery Charger Simple at Home

this i my video test. i'm from Vietnam

and this my video test circuit ( this working)

Step 1: Circuit and

what you need.

1 - diode zener 15v

1 - diode

1 - relay 5v

1 - tip41 transittor

2 - ressitor 220 ohm

1 - ressitor 1k

Step 2: Make a PCB

here is PCB i make by PROTEUS 8.4

you can download file .PDF and file Projest

Danh sách linh kiện:

" D1 " mk dùng diode thường.

" D2 " mk dùng diode zener 15v.

" R1." mk dùng điện trở 1K ohm.

" R2 " mk dùng điện trở 270 ohm.

" C1" mk dùng tụ hóa 100uf 50v.

" J3 + J2 " nó nằm gần nhau, đây là chỗ mk nối ra led chỉ thị. ( connector to led )

" J4 " là đầu ra acquy (OUT).

" J1 " là đầu vào (12V in)

Don't like it . You are charging at too high a rate and will destroy the battery . A 12 Volt battery is full at 12.5 Volts . To push current in at 15 Volts is battery murder.
